• Co-creation and Problem Posing

  Tsuruta Hiroki, Tamaki Hisashi

  現在の大学では、「産学官連携」、「文理融合」、「異分野共創」など、異なるものが相互に関係する状態を表す言葉に触れることが多い。しかし、「連携」、「融合」、「共創」という言葉の意味の違いや「異分野共創」と具体的にどんな関係があるのか等についてはよく分からない。神戸大学では、“知と人を創る「異分野共創研究教育グローバル拠点」を目指す”ことがビジョンの中で掲げられている。異分野共創とは大学や企業などのセクション、さまざまな学問分野など、分野を超えて交流し、新しいモノやコトを創造していくことを指す。異分野共創という言葉をスローガンとして取り扱うだけではなく、その概念を十分に理解し、実際の取り組みに落とし込むことによって新しい価値を生み出していくことが大学に求められていることである。本論文では、問題解決における「問題認識」を題材にして「共創」という概念、そして学問が交わる異分野共創の場である学際領域とは何かを考え、大学の研究や教育に対する影響について論じてみる。

• Novel Process Noise Model for GNSS Kalman Filter Based on Sensitivity Analysis of Covariance with Poor Satellite Geometry

  Yoji Takayama, Takateru Urakubo, Hisashi Tamaki

  One of the great unsolved GNSS problems is inaccuracy in urban canyons due to Non-Line-Of-Sight (NLOS) signal reception. Owing to several studies about the NLOS signal rejection method, almost all NLOS signals can be excluded from the calculation of the position. However, such precise NLOS rejection would make satellite geometry poor, especially in dense urban environments. This paper points out, through numerical simulations and theoretical analysis, that poor satellite geometry leads to unintentional performance degradation of the Kalman filter with a conventional technique to prevent filter divergence. The conventional technique is to bump up process noise covariance, and causes unnecessary inflation of estimation-error covariance when satellite geometry is poor. We propose a novel choice of process noise covariance based on satellite geometry that can reduce such unnecessary inflation. Numerical and experimental results demonstrate that performance improvement can be achieved by the choice of process noise covariance even for a poor satellite geometry.

  The DC microgrid system is one of hopeful candidate of the community-level power systems including renewable energy sources. This paper proposes an abstract system model of DC microgrid systems for fast and accurate simulation toward long-term virtual experiment of the DC microgrid system. We constructed the abstract system model based on the specification of the DC microgrid system. Experimental results show that the simulation results are valid comparing with the real measured data.

• 車車間通信における車種と遮蔽を考慮した車載機普及方針の一検討

  TAKAKI Yumi, MINAMI Hiroaki, OHTA Chikara, TAMAKI Hisashi

  Recent years have seen a great deal of research into Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communications, which will contribute to advances in driving support systems. In contrast to V2I communications, V2V communications offer the advantage of not requiring infrastructure, but introduction of such systems is not expected to be effective unless there is sufficient penetration by On-Board Units (OBUs). For that reason, it is essential to determine what extent of penetration should be encouraged in the initial stage in order to attain effectiveness. Therefore, we focus on the fact that even though Large Vehicles (LVs) such as large commercial freight carriers are large and tall, and are obstacles blocking V2V communications from the viewpoint of Small Vehicles (SVs), antennas on LVs could also be used to relay communications, thereby facilitating the success of such systems.
    This paper presents experiment s simulating traffic environment s consisting of mixed LVs and SVs, and examined how data V2V communication distribution rates varied with changes of the percentage of vehicles equipped with OBUs. Through the simulation experiments, by causing actively penetrate LVs, it revealed that the reception rate of SVs can be improved, and clarified some guidelines for policies that could encourage wider usage.

• 二次元通信システムにおける定在波を考慮した入力点選択型給電方式に関する研究

  TESHIMA Kosuke, MATSUDA Takasha, ZHANG Bing, INAMOTO Tsutomu, TAKAKI Yumi, OHTA Chikara, TAMAKI Hisashi

  二次元通信システムとは,シート状通信媒体を用いた通信システムであり,シート内にマイクロ波を閉じ込めて伝搬させることでシート上の端末に限定した通信と給電を同時に実現することをねらっている.しかし,二次元通信システムにおける給電には課題がある.シンクノードからシートに入力されたマイクロ波は反射によって定在波を形成する.このため受信電力が弱くなるヌル点が複数形成され,このヌル点上の端末への給電効率は低くなる.そこで本論文では,入力点の位置に応じてヌル点の位置も変化することに着目し,複数の入力点を適切に切り換えることによって複数端末に対し総給電量を減らすように給電を行う入力点選択型給電方式を提案する.また,どの入力点からどれだけの期間,どのような順番で給電すると給電量を最小化できるかという給電量最小化問題として定式化する.この問題を解くためには,ある入力点から一定時間給電後のセンサノードのキャパシタ電圧を知る必要がある.本論文では,具体的なセンサノードのインピーダンスや受信電力を知ることなく,センサノードのキャパシタ電圧の推移から一定時間給電後のセンサノードのキャパシタ電圧を推定する方法も併せて検討する.例題において,提案方式が従来の一つの入力点を使った給電方式に比べて給電時間を87.6%減らすことができ,一点入力では十分な給電が不可能な例においても提案方式によって十分な給電が可能であることが示された.

• 客獲得数向上のためのタクシー車両配車問題のモデル化と目標エリア決定ルールの構成

  OHARA Makoto, TAMAKI Hisashi

  This paper presents a way to acquire effective rule-sets for realizing the suitable distribution of cruising taxicabs based on a decentralized autonomous manner. As a result of the revision of Road Transportation Law, a taxi business have been saturated by new entries, and rookie drivers particularly have a lot of difficulty in finding passengers, because of the lack of the knowledge or experiences. Here, it is desired and effective for less-experienced drivers to design a support system which suggests potential destinations for finding passengers. As for the problem of distributing cruising taxicabs, there are many uncertainties caused by incomplete observations, e.g. locations of passengers as well as other taxicabs. Due to these uncertainties, it is impossible to distribute taxicabs optimally, e.g., by a certain centralized control. This paper proposes a decentralized and autonomous framework for distributing cruising taxicabs by adopting priority-based rules, which calculate the priorities of areas, which are to be adjusted according to the situations of each taxicab. Through some computational simulations, the effectiveness and the potential of the proposed method are confirmed.

• Reinforcement Learning for Dynamic Environment: Study on Adaptation by Partially Enlarging of the Calibration of State and Action Spaces

  Nagayoshi Masato, Murao Hajime, Tamaki Hisashi

  In general, it is not easy to put Reinforcement Learning into practical use. Our approach mainly deals with the problem of designing state and action spaces. Recently, we have proposed a co-construction method of state and action spaces. In this paper, we propose a detection method of environmental changes and a co-construction method by partially enlarging of the calibration of state and action spaces to adapt dynamic environment. In addition, the validity of the proposed method is confirmed through computational experiments using a so-called "path plannning problem" under dynamic environment.

• A Reinforcement Learning System with Switching Controllers for Continuous Action Space

  Nagayoshi Masato, Murao Hajime, Tamaki Hisashi

  In general, it is not easy to put Reinforcement Learning (RL) into practical use. This difficulty includes a problem of designing reasonable state and action spaces of an agent, i.e., satisfying two requirements in trade-off: to reduce the search space for making a learning process be fast and to keep the characteristics of the search space for seeking better strategies.
  In this paper, in order to overcome the above difficulty, we propose a RL system with switching controllers to mimic a process of a infant's motor development and a switching way to adjust the search space adaptively by referring to an entropy or a number of learning time.

• Deterministic Moel for Reactive Scheduling – Schedule Multiplexing Approach –

  SUGIKAWA Satoshi, SUWA Haruhiko, TAMAKI Hisashi

  This study proposes a new decision-making model based on static optimization from the objective standpoint that we evaluate dynamics of reactive scheduling activity. We first define a object corresponding to a event such as job/task processing and disruption, that can be represented on a time table, and then introduce a partial schedule after the occurrence time of each object. Under the assumption that information about each object is utilized after its occurrence time point, the whole schedule of a given problem can be composed by some partial schedule which does not overlap each other. The process of partial schedules composition is called schedule multiplexing in this study. Based on schedule multiplexing, we define a static reactive scheduling problem minimizing a scheduling frequency together with primal function of the job completion times, and we also formulate a mixed integer programming for that problem. The feasible solution of the problem provides the necessity minimum number of partial schedules for a given predictable events. The validity and applicability of the proposed model are demonstrated through some computational experiments.

• A Design of Dynamic Programming for Elevator Operation Problems and Increasing Its Efficiency by Reducing State Transition Models

  Tsutomu Inamoto, Hisashi Tamaki, Hajime Murao

  In the present paper, a dynamic programming (DP) approach for elevator operation problems is reported, in which two kinds of the design of DP algorithms are introduced. One (Value Iteration; VI) is rather naive imple-mentation of DP concept to the problems, and the other (Dynamic Programming on Reduced Models; DPRM) isan improved version in computational efficiency by reducing the accuracy of the utilized state transition model. The basic idea of this reduction is as follows: it is expected that dropping some situational-inputs, which rep-resent the possible causes for each state transition, with low occurring probabilities may reduce the size of the state transition model without losing the essence of a system's behavior.
  In computational illustrations, the VI and the DPRM are applied to two types of the problems of small sized, and it is observed that the computational time required in applying the DPRM is much less than that in applying the VI for each problem, while the results obtained by both methods are almost equal with respect to not only averaged but also maximum waiting time over passengers. Furthermore, the optimal and quasi-optimal plicies obtained by the VI and DPRM are compared with an existing elevator allocation rule (Call Dispatching; CD), and the results show both policies are statistically better than the CD.

• A Study on State-Space Filter for Reinforcement Learning

  NAGAYOSHI, Masato, MURAO, Hajime, TAMAKI, Hisashi

  Reinforcement Learning (RL) attracts much attention as a technique of realizing computational intelligence such as adaptive and autonomous decentralized systems. However, in general, it is not easy to put RL into practical use. This difficulty includes a problem of designing a reasonable state space of an agent, i.e., satisfying two requirements in trade-off: to reduce the search space for making a learning process be fast and to keep the characteristics of the search space for seeking better strategies. In this paper, in order to overcome the above difficulty, we propse a concept of a “state space filtering", and a method to adjust the search space adaptively by referring to an entropy. Then, through computational experiments by using a robot navigation problem with continuous state space, the validity and the potential of the proposed method have been comfirmed.

• Acquisition of Elevator Operation Rules by Using Genetics-Based Machine Learning

  INAMOTO Tsutomu, TAMAKI Hisashi, MURAO Hajime

  In this paper, we show an approach to acquire a rule which is capable of achieving effective elevator services. The allocation of elevators to hall calls is taken as the decision variable and the Pitt approach of a Genetics-Based Machine Learning (GBML) method is designed according to the representation and the characteristics of the problem. We use a rule architecture in which a combination of some measures is directly encoded as a unit-rule and an elevator allocation procedure is represented as a rule set composed of some unit-rules. Five measures are developed based on the results of the preliminary experiment and it is shown that the rule as the weighted summation of the measures (called WS) is more effective than a conventional elevator allocation rule. In computational experiments, the up-peak, down-peak and two-way traffic patterns are considered and three rule sets are acquired by applying the GBML method. Based on the results, we can confirm that the GBML method can acquire some unit-rules appropriate for the targeting traffic patterns, and we can mention that, for some presumed traffic patterns, the possibility of constructing an effective rule set by combining some specific rule sets.

• Formal Modeling of Reactive Scheduling Problems

  Sugikawa Satoshi, Imoto Takayuki, Tamaki Hisashi

  One of the important factors in building scheduling models is how well they can manage uncertainties in the dynamic manufacturing environment. Reactive scheduling, which is recognized as a practical approach to solve this problem, aims to cope with unexpected events by promptly revising or regenerating the existing schedule. However, the previous works on reactive scheduling had addressed neither its generic model nor framework. This paper proposes a formal model for reactive scheduling problems to build the problem-solving framework of the reactive approach. We first define the problem of reactive scheduling which consists of two sub problems-a schedule generation problem and a when-to-schedule problem, on the basis of a snapshot. Secondly, by using these problems, we provide a kind of taxonomy which is capable of classification of the previous reactive scheduling techniques based on the proposed framework. Finally, we demonstrate the applicability of the proposed model by some examples of classification and computational experiments.

• Expressway Traffic Simulation Using Hierarchical Autonomous Decentralized Model

  MATSUMOTO Takuya, TAMAKI Hisashi, MURAO Hajime, KITAMURA Shinzo, MAEDA Kazuo

  Recently, as performance of computers improves, it is possible to simulate larger-scale and more detailed traffic flows. In this paper, a road traffic system is modeled as a hierarchical autonomous decentralized system by constructing three kinds of the model which correspond to roads, vehicles and drivers respectively. By modeling the vehicles and drivers separately, it is possible to consider independently a physical dynamics of the system and issues related to information and decision makings. By comparing the results of simulation using the proposed model with those obtained by the Underwood model, the validity of the proposed model has been confirmed. Moreover, the typical phenomenon in actual traffic flows in sag has been also observed in the simulation. Finally, as an example of the utilization of the simulation model, the effects of the introduction of speed limit on traffic flows have been examined.

  In this paper, we deal with an extended class of flexible shop scheduling problems, and consider a solution under the condition in which information on jobs to be processed may not be given beforehand, i.e., under the framework of real-time scheduling. To realize a solution, we apply such a method where jobs are to be dispatched by applying a set of rules (a rule-set), and propose an approach in which rule-sets are generated and improved by using the genetics-based machine learning technique. Through some computational experiments, the effectiveness and the potential of the proposed approach are investigated.

  In this paper, we discuss fast training of a support vector machine for pattern classification by extracting training data around the class boundaries, and then compare performance of the support vector machine with that of a fuzzy classifier with ellipsoidal regions. First, we discuss the architecture and the training method of the support vector machine. Then, we discuss how to extract boundary data from the training data. Next, we summarize the architecture of the fuzzy classifier and discuss a feature extraction method using a two-layer neural network. Finally, we compare performance of the support vector machine with the fuzzy classifier combined with the two-layer neural network for several benchmark data sets and demonstrate the effectiveness of the fast training method.

• A Co-evolutionary Genetic Algorithm for Finding Solution Candidates and Their Genetic Expressions

  MURAO Hajime, YAMAMOTO Akio, TAMAKI Hisashi, KITAMURA Shinzo

  This paper introduces a co-evolutionary approach to Genetic Algorithms (GAs) for exploring not only solution candidates but also their genetic expressions. Two GAs cooperate each other; one explores the arrangement of genes while the other explores the attributes of genes. The genetic expression of a solution candidate is determined by a couple of individuals from the two GAs, therefore it is not modified directly but modified through genetic operations on the individuals. This improves the intrinsic difficulty of GAs that the genetic expressions of solution candidates should be determined beforehand so that unknown better schemata will have the shorter expressions. According to the schemata theorem, the shorter expressions are rather robust to the destruction by the genetic operations and will cause an exponentially increasing number of the solution candidates containing the schemata with the short expressions in successive generations. Two typical ways of determining genetic expressions of the solution candidates from the arrangement and the attributes of genes are formalized and discussed in terms of the length of the expressions for the schemata. They are applied to the 3-bit deceptive problems introduced by D.E. Goldberg which are well-known by that the efficiency of the genetic expression can be controlled by the fitness evaluation procedure. As a result of computer simulations, the proposed method showed a better performance than the simple GA. The efficiency of the proposed method, especially from the view point of adaptive search of the genetic expression, is also discussed.

• A Robust Fuzzy Classifier with Ellipsoidal Regions

  EGUCHI Takashi, TAMAKI Hisashi, ABE Shigeo

  In this paper, we discuss a robust training method for a fuzzy classifier with ellipsoidal regions. First, we define a fuzzy rule for each class. Next, we determine the weight for each training datum Dy the two-stage method in order to suppress the effect of outliers. Then, using these weights, we calculate the center and covariance matrix of the ellipsoidal region for each class and tune the Fuzzy rules. After tuning, to further improve generalization ability, we tune fuzzy rules between two classes using the training data in the class boundary. We demonstrate the effectiveness of our method using four benchmark data sets.

• A Genetic Algorithm Approach to Optimization Problems with Uncertainties

  TAMAKI Hisashi, ARAI Toshihiko, ABE Shigeo

  In this paper, we propose a method of optimum seeking in an uncertain environment by extending the conventional genetic algorithms (GA). The key point of our approach is to evaluate an individual not directly by an objective value of a corresponding solution currently observed, but by accumulating values which have been observed at preceding generations. Finally, we confirm the effectiveness of our extended GA through some computaitional experiments using simple function optimization problems.

• Introduction of a State Feedback Structure for Adjusting Priority Rules in Production Scheduling

  TAMAKI Hisashi, OCHI Michiari, ARAKI Mituhiko

  This paper proposes a method of generating and selecting rules for adjusting the priorities of jobs by using a genetics-based machine learning (GBML) technique, where a state feedback structure is newly introduced. In applying the GBML, we use the Pitts approaches, where the set of rules (rule-set) are represented symbolically as an individual of genetic algorithms, and the fitness of an individual is calculated based on the makespan of the schedule generated by using the rule-set. As for a rule representation, we consider several attributes and status of a job in order to calculate its priority as a weighted sum of these attributes. We actually carried out computational experiments to simple problems with an intree-type precedence relation, which indicate that the method of applying the GBML is effective for finding and selecting good rule-sets.

• Parallel Machine Scheduling Problem with a Non-Regular Objective Function:Minimizing the Sum of Earliness and Tardiness Penalties

  TAMAKI Hisashi, SUGIMOTO Tatsuhiko, ARAKI Mituhiko

  In this paper, we study identical parallel machine scheduling problems with a non-regular objective function, i.e., with the sum of earliness and tardiness penalties. We adopt the decomposition approach, where an original problem is decomposed into three kinds of sub-problems: to determine the assignment of jobs to machines, the sequence of jobs on each machine, and the start time of each job. Then, we construct solution methods of each sub-problems by composing new heuristic procedures as well as adopting meta-heuristic algorithms. Finally, this paper shows the good properties concerning the optimality of the proposed methods by both theoretical and empirical ways.

• A Genetic Solution for the Traveling Salesman Problem by Means of a Thermodynamical Selection Rule

  MAEKAWA Keiji, MORI Naoki, TAMAKI Hisashi, KITA Hajime, NISHIKAWA Yoshikazu

  For successful applications of the genetic algorithm, there are two important points to be considered. The first point is the design of the fitness landscape introduced by the representation of the solution as a chromosome and searching operations such as crossover and mutation. The second is control of the convergence brought about by the selection operation. In the conventional implementation of GA, these two points are mutually dependent, i.e., a suitable selection pressure varies largely depending on, e.g., the crossover operator. Hence, it requires much trial-and-error effort to find a nice configuration of GA. In the present paper, the authors apply a novel selection rule, the Thermodynamical Genetic Algorithm (TDGA) proposed by Mori et al. to the traveling salesman problem (TSP), and propose an adaptive annealing schedule of the temperature in TDGA. Computer simulation with several crossover operators for TSP shows that TDGA reduces the mutual dependency between the fitness landscape and the convergence process. Furthermore, TDGA is applied to a hybrid algorithm which combines GA with the 2-opt method, a local search technique. The effectiveness of the TDGA in the hybrid approach is also confirmed through a comparison with other methods for solving the TSP.

• Application of Search Methods to Scheduling Problem in Plastics Forming Plant : A Binary Representation Approach

  TAMAKI Hisashi, HASEGAWA Yoshisige, KOZASA Junji, ARAKI Mituhiko

  In this paper, a scheduling problem in a plastics forming plant is studied. This problem basically belongs to the class of unrelated parallel machine problems, but includes several restrictions which originate from the necessity to use auxiliary equipment. Thus it can be regarded as an example of complex scheduling problems arising in industries. The paper presents a new scope for the study of practical scheduling problems by proposing a method to solve them without relying upon dispatching rules. First, we transform the scheduling problem to a mathematical programming problem, and represent feasible schedules by binary strings. This formulation enables to use the search methods (such as simulated annealing methods, genetic algorithms, etc.). We actually coded several search methods and carried out computational experiments for the problems of practical size. Results indicate that our methods can give satisfactory solutions to the considered scheduling problem.

• A Method for the Traveling Salesman Problem Based on the Genetic Algorithm

  MAEKAWA Keiji, TAMAKI Hisashi, KITA Hajime, NISHIKAWA Yoshikazu

  The genetic algorithm (GA) is an optimization technique simulating the process of natural evolution, and it has been successfully applied to several optimization problems which are difficult to solve exactly by conventional methods. This paper proposes a new method for solving the traveling salesman problem (TSP) based on the GA. In applications of GA to TSP proposed so far, a coding where the chromosome represents a list of cities arrayed in the visiting order has been mainly used. However, in such a coding, we have to devise a crossover operator that keeps each chromosome to be a permutation, and it inevitably causes a difficulty in inheritance of tour characteristics.
  The present paper proposes a new method in which a genetic coding represents edges of the tour, and a crossover operator exchanges the edges of the parent tours. The effectiveness of the proposed method is confirmed through several computational experiments, including a comparison with another typical method. Furthermore, the paper proposes an algorithm which combines GA with the 2-opt method, a local search technique. The effectiveness of this algorithm is also confirmed through a comparison with other methods for solving the TSP.

• Generation of a Set of Pareto-Optimal Solutions by Genetic Algorithms

  TAMAKI Hisashi, MORI Masakatsu, ARAKI Mituhiko

  In this paper, a method of applying the Genetic Algorithm (GA) to multi-criteria optimization problems is proposed. First, the reproduction operator in GA is made so that the selection is performed in parallel according to each criterion and, at the same time, the Pareto-optimal solutions are always reproduced if such appear in the population. Then, through computational experiments, it is shown that not only one of the Pareto-optimal solutions of a problem but a set of such solutions is obtained by a single run of the proposed method.

• Solution of the Job-shop Scheduling Problem with Consideration of In-process Buffer Capacity

  TAMAKI Hisashi, NISHIKAWA Yoshikazu

  Recently, as the diversification of demand and the progress of production technology result in a wider variety of products, the necessity of scheduling and inventory control is increasing. This paper deals with methods of solution for a job-shop scheduling problem considering the capacities of in-process buffers. To this problem, the authors have proposed three kinds of ways of modeling the problem, i. e., a disjunctive graph (DGR) model, a timed Petri net (TPN) model and a Gantt chart (GTC) model. The present paper proposes several methods of solution based on these models. First, to the DGR model, a conventional algorithm, e. g., a branch-and-bound method, for the ordinary job-shop scheduling problem is applied. Second, to the TPN model, a simulation-based algorithm on TPN, i. e., an algorithm to obtain an optimal schedule among non-delayed schedules by using the branch-and-bound method is proposed. Further, the TPN model is extended to be fit for the problem in repetitive production processes. Third, to the GTC model, both an algorithm to obtain an optimal schedule by using the branch-and-bound method and an algorithm to obtain an approximately optimal schedule by using the list-scheduling method are proposed. Finally, results of several computational experiments are presented, in which the effects of buffers on schedule are investigated numerically.

• Modeling of Job-shop Scheduling Problem with In-process Buffer Capacity

  TAMAKI Hisashi, NISHIKAWA Yoshikazu

  In recent years, as the diversification of demand and the progress of production technology have brought about a wider variety of products, the necessity of scheduling and inventory control is increasing. This paper deals with a job-shop scheduling problem with consideration of the capacities of in-process buffers, and proposes three kinds of methods of modeling the problem. First, the problem is formulated mathematically into a mixed integer programming (MIP) problem, and referring to the MIP, a way of modeling the problem into a disjunctive graph, is presented. Once the problem with in-process buffers is represented by the disjunctive graph, it can be solved effectively by using a conventional algorithm. e. g., a branch-and-bound method, for the ordinary job-shop scheduling problem. Second, the problem is described by another type of the MIP and is modeled using an extended timed Petri net which is useful as a tool for various kinds of simulation. Third, the problem is modeled by using a Gantt chart which is often used to represent a schedule graphically. This model is suitable for developing heuristic methods of scheduling.

• A Study on Management of ContentID/Cache Location based on Estimation of Content Popularity for In-network Guidance

  ONIZUKA Takaki, KATAOKA Naomi, TAKAKI Yumi, OHTA Chikara, TAMAKI Hisashi

  Circulation of large-size contents like high-definition video leads to increasing content server load and core network traffic. Content oriented network (CON), which is expected to realize efficient content distribution, is vigorously studied as a future Internet. A Mapping Server with Cache-location Resolution (MSCR) has been proposed, which provides functions to resolve content ID and not only content sever location but also prospective cache locations in order to effectively utilize in-network caches by guiding content requests to content cache locations. Its performance is, however, evaluated only under assumption that content popularity is time-invariant. In this paper, we verify the effectiveness of MSCR under more realistic assumption where content popularity is time-variant. VPCL (Variable Prospective Cache Location) is also proposed, which varies the number of stored cache locations for each content according to its estimated popularity, so that ineffective query guidance is reduced. Simulation results show that MSCR is effective even in the case of time-variant content popularity and VPCL reduces unexpected query guidance.

  An emergency vehicle such as an ambulance and a police-car needs to travel to a destination as quickly as possible. As a field of ITS (Intelligent Transport Systems), there is a lot of research on systems to support drive of emergency vehicles. Performance of such systems, however, has not been evaluated enough especially in urban environment. In this paper, we focus on the situation that an ambulance goes to a hospital via a traffic accident site in urban, and in this situation, we evaluate the effectiveness of emergency vehicle drive support based on vehicle-to-vehicle communications. We consider two types of schemes: in one scheme, an emergency vehicle broadcasts information on its location and velocity to prompt neighboring vehicles to avoid slowing down, changing lane, and entering intersection; in another scheme, an emergency vehicle floods information on its path to drive to prompt other vehicles to avoid using the path. Through simulation results, we confirm that the latter scheme shortens traveling time of an ambulance by 10.4% compared with the case of no support.

• A study on cache suppression control according to content popularity for in-network guidance

  KAWABATA Hiroki, ONIZUKA Takaki, TAKAKI Yumi, OHTA Chikara, TAMAKI Hisashi

  In recent years, the popularity of large contents such as high-definition video and music is increasing content server loads and the amount of traffic on backbone networks. When a user obtains a content, he/she needs to resolve the content name (ID) as well as content server location. To mitigate the above problem, we have already proposed, a Mapping Server with Cache-location Resolution (MSCR), which resolves prospective cache locations (PCLs) close to the requesting user, and comfirmed the efficiency by some simulations. In this paper, we introduce an improved version of MSCR, named MSCR with Cache Suppression (MSCR/CS) which suppresses excess cache duplication of high popularity contents in a netowrk in order to increase the variety of content caches that enable users to obtain a content within the network.

• A Study on Transmission Power Control for Improvement of Throughput in Wireless LAN Access Networks

  NISHIUE Toshiki, TAKAKI Yumi, OHTA Chikara, TAMAKI Hisashi

  Internet is being transformed to "Internet of Things" to accommodate many things. In this study, we focus on IEEE802.11 as wireless access networks for IoT. In recent years, IEEE802.11APs (Access Points) using a same channel are often deployed near to each other. Such situation leads to "exposed terminal problem," where a terminal misses an opportunity of successful transmission due to unnecessary carrier sense to transmission by another terminal which belongs to a different AP. In this paper, we verify the effectiveness of transmission power control for uplink in order to mitigate exposed terminal problem. We analyze a simple model, and further perform packet-level simulations in more practical scenarios. As results, we confirm that transmission power control enhances uplink throughput.

• An Efficient Flooding Scheme for V2V Communications Considering Intersections of Urban Area

  CAO Ke, KINOSHITA Atsushi, TAKAKI Yumi, OHTA Chikara, TAMAKI Hisashi

  In Vehicle-to-Vehicle (V2V) communications, broadcast is expected to disseminate information t0 locations beyond the transmission range of individual nodes. However, due to shadowing of buildings in urban area, the V2V communications at an intersection is unreliable. Thus it is difficult to disseminate information to all directions at an intersection. In addition, most of existing protocols need to use digital map which is costly and hard to update frequently. In this paper, we proposed an efficient flooding scheme for V2V communications in urban environment without digital map. We identify intersection by the difference of theoretical RSSI (Received Signal Strength Indicator) value and real RSSI value. The larger difference means larger shadowing of obstacles. We give the higher precedence to the vehicles in different street and the vehicles in further distance to sender. Simulation results show that this scheme achieves a higher reception ratio and a shorter delivery time than existing broadcast protocols.

• Proposal of Detour Multipath Routing Protocol in Wireless Sensor Networks for Data Gathering

  FUJITA Keisuke, TAKAKI Yumi, OHTA Chikara, TAMAKI Hisashi

  In battery-powered wireless sensor networks (WSNs), system lifetime is strongly affected by drain of nodes' batteries. In severe environments such as disaster scenarios, WSNs also need to be tolerant to failure or loss of nodes due to external factors. The aim of this paper is to increase data collection ratio by enhancing tolerance to nodes' failure or loss while keeping system lifetime as long as possible in data-gathering WSNs. In this paper, we propose not only a detour multipath data gathering protocol called "Side Trip (ST)" scheme to enhance regional node-failure tolerance but also an improved version of ST called "Side Trip Network Coding (STNC)" scheme which utilizes network coding to reduce redundant packets without affecting the system lifetime significantly. In datagathering WSNs, nodes further away from sink node tend to have less relayed packets. In ST scheme, then, a node establishes another detour path which partially traces on nodes same hop away from the sink in order to increase the tolerance to geographically-correlated node-failure. In STNC, redundant packets from different source nodes are network-coded into an encoded packet in order to reduce redundant packets. By comparison of ST, STNC, and SMRP which is an existing multipath protocol by means of a self-developed simulator, it is shown that STNC and ST enhance tolerance for node failure compared with SMRP without significant influence to system lifetime.

• Performance Evaluation of V2V Information Dissemination Schemes by Network Simulations Considering Urban Area

  KINOSHITA Atsushi, CAO Ke, TAKAKI Yumi, OHTA Chikara, TAMAKI Hisashi

  Recently, there have been an increase in research into VANETs (Vehicular Ad-hoc NETworks)communications, and various flooding schemes have been proposed for information dissemination in VANETs. These flooding protocols, however, were often evaluated under unrealistic conditions such as small-scale, line-of-sight, and static mobility environment. In this study, we evaluate how the performance of some well-known flooding schemes are affected according to whether vehicles are mobile or static and whether buildings exist or not. Simulation results show that these factors strongly affect the performance of flooding schemes.

• Improvement and Evaluation of Rate Adaptation based on Average Fade Region Duration Estimation for IEEE802.11

  MISHIMA Chie, ROSLAN Irda, INAMOTO Tsutomu, TAKAKI Yumi, OHTA Chikara, TAMAKI Hisashi

  Most rate adaptation schemes for IEEE802.11 such as ARF and AMARF decide to increase the data rate when the count-based success threshold of sequential frames is successfully transmitted. Unfortunately, ARF and AMARF do not work well if the terminals are not greedy to send messages and if the message length is vanable. We have proposed an RA scheme, which we call MARFFE (Multi-rate Auto Rate Fallback with average Fade region duration Estimation), it uses time-based success thresholds instead of the count-based one. In this manuscnpt, we improve MARFFE to promptly adapt changing environment, and evaluate MARFEE, AMARF, and ARF to confirm the effectiveness of MARFFE

• Performance Evaluation of Distributed User Association based on User Utility in Wireless Networks

  IWAMI Takahiro, INAMOTO Tsutomu, TAKAKI Yumi, YAMORI Kyoko, OHTA Chikara, TAMAKI Hisashi

  In recent, public WLANs based on IEEE802.11 standard are widely deployed. In an environment that several APs (Access Points) are available, a UTE (User Terminal Equipment) needs to choose an AP to associate. In such a case, the UTE associates with the AP with the strongest RSSI (Received Signal Strength Indicator). This simple and conventional scheme, however, may make the UTE choose a heavily loaded AP even though there is any unloaded AP. Thus, it possibly leads to inefficient network utilization. Then, so far, more sophisticate schemes for AP association and/or user guidance have been proposed. To the best of our knowledge, however, these existing schemes do not take into account of individual difference among UTEs with respect to user utility, physical data rate, traffic characteristics such as traffic demand and packet length. In this paper, we propose a distributed user association control considering such diversity of UTEs. Through our numerical simulations, we confirm that our distributed control scheme can improve user utility.

• A Study in Input-selection-based Power Supply Method Considering Standing Wave for Two-Dimentional Communication System

  TESHIMA Kosuke, MATSUDA Takashi, ZHANG Bing, INAMOTO Tsutomu, TAKAKI Yumi, OHTA Chikara, TAMAKI Hisashi

  Two-dimensional (2D) communication system is a novel communication system which utilizes surface of a sheet as a communication medium. 2D communication systems provides wireless power supply as well as high-speed data transmission to sensor devices. Standing wave, however, appears in a 2D communication sheets due to reflection of the microwave at the edges. As a result, over the sheet, there are some null points where a sensor node can receive little power. Therefore, in this paper, we propose a power supply scheme, called "multi-input scheme," which switches multiple power input points adequately in order to reduce total power supply. This scheme leverages the fact that different power input points forms different standing wave. In case of multiple input points, an important issue is which input point is selected and how long it is powered since to shorten power supply period leads to save power consumption. To do so, we formulate this as a minimization problem. Numerical results show that the proposal scheme can shorten power supply period compared to a conventional single-input scheme.

• A Study on Content/Location Mapping for In-network Guidance

  KAWABATA Hiroki, HASHIMOTO Kensuke, TAKAKI Yumi, OHTA Chikara, TAMAKI Hisashi

  Breadcrumbs (BC) scheme has been proposed for content distribution in next-generation networks. In BC scheme, when a user obtains a content via networks, first, by using Mapping Server (MS), he/she needs to resolve a location of a server which stores the content and then issues a query toward the server. If the query encounters a corresponding BC on the way to the server, it is guided along the BC trail toward a cache which may store the content. If the query heads toward a prospective cache initially instead of the server, it is expected that the server load and traffic of core-networks can be reduced. In this paper, we study a MS to resolve cache-locations in addition to server-locations, which we call "MSCR: Mapping Server with Cache-location Resolution." Simulation results show that MSCR can suppress server-load and traffic of core-network compared with MS.

• Performance Evaluation of Flooding Protocols in VANETs Considering Shadowing

  MURAKAMI Hiroaki, TAKAKI Yumi, OHTA Chikara, TAMAKI Hisashi

  In recent years, with the fast development in ad-hoc wireless communications and vehicular technology, it is expected that VANETs (Vehicular Ad-Hoc Networks) will be realized. VANETs enable vehicles to easily collect and disseminate emergency information in short time. In urban areas, corner-lots at intersections are often occupied by buildings. In general, radio signal remarkably decreases when turning a corner from a LoS (line-of-sight) onto a NLoS (non-line-of-sight) street at an intersection. Therefore, emergency information is not disseminated efficiently into NLoS streets. In past studies on ITS, only small-scale simulations were executed and shadowing due to buildings were not taken into account. In this research, we try to run large-scale simulations of flooding protocols to disseminate emergency information, in which influence of shadowing is considered.

• A Study on Estimation of Session-based Throughput in IEEE802.11 Wireless Access Network

  IWAMI Takahiro, TAKAKI Yumi, OHTA Chikara, TAMAKI Hisashi

  In recent years, public wireless local area networks (WLANs) access points (APs) using IEEE802.11 have been widely deployed. A wireless terminal may associate with an appropriate IEEE802.11 AP if it can predict throughput of up-link and down-link. In this study, we propose a simple method to estimate up-link and down-link throughput of IEEE802.11 AP service. By comparing results of simulations and those of the method, we have confirmed that the method can estimation the up-link and down-link throughput on session basis accurately.

Besides, the work scheduling problem contains so many parameters concerning the demands of workers as well as the conditions on works. Then, a way of parameter identification adopting mathematical programming approach is designed. Finally, through some computational experiments using practical examples, the effectiveness and the potential of the proposed approach are investigated.

  In case of considering human-machine systems such as robots, vehicles, etc., it is needed to take care of not only human intelligence but also human skill. Then, in order to assist or support human for certain operations, the skill-level of the human should be taken into account. This study aims at developing a framework of practical decision support systems, where racing kart driving is taken as an example of human-machine systems concerning both intelligence and skill. In this paper, as a preliminary step, the problem of racing kart driving is formally represented, and the basic framework for on assistance of drivers' skill is investigated.

• Proposal of Rate Adaptation Scheme based on Average Fade Region Duration for IEEE 802.11

  MISHIMA Chie, TAKAKI Yumi, OHTA Chikara, TAMAKI Hisashi

  In IEEE802.11a/b/g/n, which are widely used as wireless LAN standards, multiple modulation rates are available. Then adaptive modulation schemes for IEEE802.11 wireless LAN has been studied in order to select an adequate modulation rate according to channel condition. ARF, which is known as a practical adaptive modulation scheme, has two drawbacks: 1) unnecessary and undesirable rate decrease due to frame collisions, and 2) low following capability to fluctuation of channel condition. In this paper, we propose a novel adaptive modulation scheme based on CARA, named CARA-FE, which estimates adequate timing for rate increase by learning average rate region duration. Simulation results show that CARA-FE achieves higher throughput than existing schemes, ARF, AMARF, and CARA.

• Study on Load Balancing Handover Considering Mobility Information for Multi-band Wireless Access Systems

  TANAKA Daiki, TAKAKI Yumi, OHTA Chikara, TAMAKI Hisashi

  In recent years, terminals using multi-band wireless access systems are spreading because diverse wireless access systems are available. In this paper, we clarify the impact of terminal's mobility on channel capacity in an environment where a multi-band wireless system is available. Furthermore we investigate the effect of a load balancing handover based on channel capacity considering terminal's mobility. To doing so, we define a channel model, channel capacity model, channel allocation model, and user utility model. Our simulation results show that the capacity-based access point selection with load balancing handover considering terminal's mobility achieves higher user utility than the access point selection without load balancing handover.

• Proposal of Hop-aware In-network Query Induction Scheme for Contents Cache

  HASHIMOTO Kensuke, TAKAKI Yumi, OHTA Chikara, TAMAKI Hisashi

  As a scheme for content distribution in next-generation networks, Breadcrumbs (BC) scheme, in which query induction information is stored in routers on the path which the corresponding content is delivered, has been proposed. In BC scheme, a query is diverted once toward the node which recently retrieves the content. As a result, the query possibly pass the near source, which causes a loss of opportunity to shorten content acquisition time. Therefore, in this paper, we propose Hop-aware Breadcrumbs (HA-BC) scheme, in which a query induction information includes latest content acquisition node, which enables a query to be diverted toward closer node, the latest content acquisition node or the server node. We also show some simulation results to compare HA-BC and BC scheme. From simulation results, we confirm that HA-BC shortens content acquisition time compared with BC.

• Macrocell batch resource allocation for a co-channel macrocell/femtocell network

  AFOLABI Akindele Segun, OHTA Chikara, TAMAKI Hisashi

  This research work proposes an interference mitigation strategy that adjusts the maximum transmit power of femtocell base stations so as to reduce the aggregate cross-tier interference received by nearby macrocell users. Most of the existing research works considered resource allocation and interference avoidance separately but in this work, both are investigated together. A resource block allocation strategy which ensures that each user served by the macrocell or femtocell base station receives a fair share of the resource blocks available in the serving cell is discussed in this work. In the case of femtocell, a non-linear optimization model is developed to maximize the total cell throughput. The optimisation process comprises of two parts, channel allocation and power allocation, which are treated separately. Simulation results show that the proposed scheme can increase considerably the average macrocell throughput in an interference-prone multilayer wireless network as the case of macro-femto cellular networks.

• A Total Dominant Pruning-based Scheme with Passive ACK and Active NACK for Reliable Broadcasting in MANETs

  DIAO Yiyuan, TAKAKI Yumi, OHTA Chikara, TAMAKI Hisashi

  Flooding is one of the most fundamental operations in mobile ad-hoc networks; however, pure flooding suffers from the problems of excessive redundancy, contention and collisions, which are referred to as "Broadcast Strom Problem." The objective, to reduce broadcast redundancy while still providing high delivery ratio, is a major challenge in MANETs. In this paper, we propose two schemes based-on Total Dominant Pruning with application of Passive ACK and Active NACK to provide reliable broadcast in MANETs. Further we show simulation results on delivery ratio and dissemination delay in Rayleigh fading environment in order to verify the effectiveness of the proposed schemes.

• Transmission power control to aim at equalization received SINR in wireless multi-hop networks

  WATANABE Shunsuke, TAKAKI Yumi, OHTA Chikara, TAMAKI Hisashi

  TPC(Transmission Power Control) has a great potential to improve the throughput of high-density multi-hop wireless network. TPC has a different kind of hidden terminal problem and various solutions are proposed for the problem. We assume an 802.11 single-channel environment and any control packets such as RTS/CTS are not used. We focus on the fact that interference at receiving nodes varies according to the transmission power in such environment, and propese the a novel TPC called EqPC(Equalized Power Control) which aims at equalization received SINR.

• Comparison of Interference Reduction Schemes by Femto Base Stations to Macro Cell Users

  TANABE Yuya, AFOLABI Akindele Segun, OHTA Chikara, TAMAKI Hisashi, TANAKA Yoshizo, YAMAMOTO Takashi, OKADA Yoji

  In 3GPP TR25.820, three kinds of approaches, access control, bandwidth control, and power control, to reduce interference from femtocell to macrocell are examined. Further, five types of configurations as combinations of these approaches are also discussed. The relative effectiveness among these configurations are, however, not clear since they are not compared in the same scenario enough. Therefore, at the beginning in this paper, under the simple scenario where one femto-cell exists in one macro-cell, we compare Shannon capacities of the following three configurations: 1) Open Access, Co-channel, and Fixed Power, 2) CSG (Closed Subscriber Group), Dedicated Channel, and Fixed Power, 3) CSG, Co-channel, and Adaptive Transmission Power. We also investigate conditions that transmission power control is effective.

• User Selection Algorithm Considering Reliability of CSIT for MU-MIMO Systems Using Zero-Forcing Beamforming

  YAMABAYASHI Jun, OHTA Chikara, TAMAKI Hisashi, KANEKO Megumi, HAYASHI Kazunori

  This paper proposes a user selection algorithm for multi-user multiple input multiple output (MU-MIMO) system using Zero-Forcing Beamforming (ZFBF). A base station (BS) employs the channel response between antennas of the BS and those of mobile stations (MS) for adjusting transmission weights. The BS gets the channel response by, for example, receiving feedbacks from MSs. Because the channel response varies over time, it involves the error margin and cannot be reliable as time passes by. When responses of channels with the error margin are used for selecting users and adjusting transmission weights by the BS, qualities of channels reduce as orthogonality of channels is lost and the interference between users increases. When MSs frequently give feedbacks of the channel response to the BS, the overhead in the uplink control increases. In this paper we proposed a user selection algorithm which employs a metric representing reliability of the channel response for balancing the sum rate capacity with the feedback frequency. The simulation results display that the proposed algorithm achieves larger sum rate capacity with lower feedback frequency than a conventional algorithm.

• 2302 The Straight-Ahead System for Electric Wheelchairs on Slopes II

  OHARA Makoto, TAMAKI Hisashi, NAGAYOSHI Masato, HASHIZUME Tsutomu

  Crossing slopes, electric wheelchairs deviate from their straight course under the influence of gravity. In order to keep traveling directions of the electric wheelchairs on slopes, the users must frequently operate input devices. This is a severe problem for the users who operate electric wheelchairs by switches. The switching devices are less smooth than the joysticks on veering. This research aims at reducing the operation strain on the slopes, and presents a system that guides the electric wheelchairs to run straight-ahead by only one operation. The proposed system has a feedforward controller and a feedback controller on the basis of posture angles of the electric wheelchairs. We mounted a prototype system on a ready-made electric wheelchair, and made a learning experiment on the system in a simulated environment.

• A Study on An Acquisition Method for Action-Less Rule Sets by means of Its Application to Job-shop Scheduling Problems

  Inamoto Tsutomu, Matsumoto Takuya, Ohta Chikara, Tamaki Hisashi, Murao Hajime

  本稿では，後件部を持たない単位ルールからなるルールベース獲得手法の初等的な調査結果を報告する．このルールベースはエレベータ運行計画問題を対象として考案したものであり，ある時点でとることが可能な各決定に関して所与の指標を計算し，その組合せと適合する単位ルールがルールベースに含まれる場合に，対応する決定を選択する．含まれない場合，何らかのデフォルトルールにしたがって決定を選択する．このような設計から，決定が離散的であるさまざまなリアクティブスケジューリング問題へ適用できると考えられる．その一例としてジョブショップスケジューリング問題をとりあげ，獲得されるルールの有効性などを調査する．

• 3A2 AN APPROACH USING GENETICS-BASED MACHINE LEARNING TO COMPLEMENTING LEGACY RULES FOR THE ELEVATOR OPERATION :

  Inamoto Tsutomu, Ohta Chikara, Tamaki Hisashi, Murao Hajime

  In this paper, an approach using a Genetic-Based Machine Learning (GBML) method to acquire rule sets which complement legacy rules for the elevator operation is shown. A rule set is designed to be comprised of unit-rules, each of which encodes an elevator's augmented attribute vector and matches an arbitrary elevator which has such attributes. The GBML method is built in the Pittsburgh-style and tailored for acquiring such rules sets. In computer illustrations, the effectiveness of acquired rule sets is displayed as for three traffic patterns.

• 1209 The Straight-Ahead System for Electric Wheelchair on a Slope

  OHARA Makoto, TAMAKI Hisashi, NAGAYOSHI Masato, HASHIZUME Tsutomu, OMORI Kiyohiro

  This paper presents an approach which assist users for driving electric wheelchairs to go straight ahead on slopes, in order to reduce their strains of operations by switches while crossing on a slope. The users who cannot control joysticks due to some kind of physical disabilities, have to use input devices of the simple switch type. It causes one of the crucial problems on crossing slope, where the users have to operate switches more frequently than joysticks so that the wheelchair should go straight. On this approach, the straight-ahead system controls input voltages of left and right motors by reading the yaw angle of the wheelchair. We make a prototype system with simple feedback control. Through the experiments with the prototype system, the effectiveness and the applicability of the proposed system have been confirmed.

• ハイブリッド・アプローチによる最適化 : 数理計画モデルをベースとしたフレキシブルショップ・スケジューリングを例として

  玉置 久, 榊原 一紀

  線形計画や整数計画の分野において,最先端のアルゴリズムを実装した数理計画パッケージの性能は,ここ数年飛躍的に向上している.とは言え,現実規模の問題にそのまま最適化アルゴリズムあるいは数理計画パッケージを適用して解を求めるには,まだまだ限界のあることも事実である.このような状況において,ヒューリスティクスと数理計画法をハイブリッドする形での解法構成が効果的であると考えられる.本稿では,問題の分散構造とハイブリッド解法の形態を概観するとともに,フレキシブルショップ・スケジューリング問題を例として取り上げ,混合整数計画モデルに基づくハイブリッド解法の一例を紹介する.

• 2B2 HIERARCHICAL APPROACH WITH INFORMATIONAL FEEDBACK FOR PICKUP AND DELIVERY PROBLEMS(Technical session 2B: Vehicle scheduling and communication) :

  Sakakibara Kazutoshi, Noishiki Manabu, Watanabe Shinya, Nishikawa Ikuko, Tamaki Hisashi

  This paper discusses meta heuristic approaches for the transportation problems in the logistic systems, the elevator systems and so on. Most of these problems include assignment of each customer to a certain vehicle and routing of each vehicle, and a hierarchical approach is widely applied, in which the assignment and the routing are searched alternatively. In this paper, we form the hierarchical solution for the pickup and delivery problem as a general model of practical transportation problems. Here, in implementing the hierarchical approach, an informational feedback is newly introduced, so that not only objective values but also a part of decisions themselves should be utilized for making a neighborhood search more efficient. The influence of frequency of feedback is numerically evaluated, and the effectiveness and the possibility of the hierarchical approach with feedback are examined through a series of computational experiments.

• 3-A-2 MATHEMATICAL MODELING AND HYBRID SOLUTION FOR A CLASS OF FLEXIBLE SHOP SCHEDULING PROBLEMS :

  Sakakibara Kazutoshi, Tamaki Hisashi, Murao Hajime, Kitamura Shinzo

  In this paper, we consider an extended class of flexible shop scheduling problems. First, we translate the problem into a mathematical programming formula, i.e., a mixed-integer programming problem. This makes it possible to apply standard packages of mixed integer programming solvers, and while lots of computational time is required in general, to obtain the optimal schedule. Then, in order to seek such schedules as close to the optimal, we compose a hybrid approach in which an integer programming method and a genetic algorithm are combined. Through some computational experiments, the effectiveness and the potential of the proposed approach are examined.

  To cope with recent globalization of economy and diversified customers' request, enterprises have required to estimate the change of customers' preference immediately and draw up the effective business strategies in order to overcome the competitors in the market. However, it is not easy to predict the customer's and competitors' behavior, both of which are most important to determine the effective strategies. In the presence, many enterprises analyze the behavior of the customers by the conventional statistical methods and reflects the results to own strategies. In this research, we try to realize a demand chain simulation system that can analyze and support to plan the business strategies based on the research on the biological manufacturing systems. As the first step of the research, we develop a prototype system of demand chain simulator for soft drink business through vending machines. The simulation results suggest that the simulation system can be applicable to the real market.


• A Study on Systematic Analysis on Sustainable Cycle-Oriented Social System

  Many studies have been conducted in order to develop a sustainable cycle-oriented social system. Those studies focused on top-down processes, based on the belief that strong restrictions such as laws are effective. We consider this belief to be suspect and that it is desirable to form a social system from the bottom up while retaining creativity and diversity in the decision making process of not only manufactures but also consumers. In order to analyze and attain a sustainable society by focusing on the above viewpoints, four new approaches are proposed : complexity, value creation, indirect control method and latent function. At first, we discuss the nature of a cycle-oriented social system by using the abstract rewriting system on multisets (ARMS) and we found that a system which has a high level of giving great complexity dose not last for very long and there is an appropriate complexity level for sustainable society. Second, we focus on the consumer's value creation to form the sustainable society and showed a method to help the consumers to do the value creation. Third, we established an Indirect Control Method for control the behavior of the sustainable social system using the agent-based simulation. In this study, we shows some examples of Indirect Control Method and verify the validity of Indirect Control Method. Forth, we formulate the degree of Latent Function, so as to evaluate artifact' future comprehensively and concretely. We perform questionnaire surveys about drink containers, in order to determine the weights of the coefficients of the formula.

  進化的計算では,コード化/交叉の設計および世代交代モデルの設計が基本となり,前者は形質遺伝という視点,後者は多様性維持という視点が重要である.本年度は,過去2年間の実績を踏まえて,工学的応用可能性を意識しつつ研究を進め,下記の点において大きな研究成果を得た. (1)コード化/交叉の設計: 巡回セールスマン問題(Traveling Salesman Problem:TSP)を対象に枝交換交叉(Edge Assembly Crossover)を考案し,1万都市規模の問題Pの最適解を効率よく見いだすことに成功した.また,ジョブショップスケジューリング問題(Job Shop Scheduling Problem)を対象にIntermachine Job-based Order Crossoverを考案し,ベンチマークFT10×10,FT20×5に適用して,最適解を非常に高い確率で見いだすことに成功した.さらに,関数最適化を対象に正規分布交叉(Normal Distribution Crossover)を考案し,従来法と比べて,多峰性関数に対して頑健な性能を示すことを確認した. (2)多様性維持に優れた世代交代モデルについて: 多様性維持に優れた世代交代モデルとして提案したMGG(Minimal Generation Gap)について,最小騙し問題を用いてその有用性を解析した. (3)工学的設計問題への応用: 進化的計算の工学的設計問題への応用として,レンズ設計,並列機械スケジューリング,VLSIフロアプラン設計,プリント基板設計への適用を試み,有用性を確認した.特に,レンズ設計においては,従来の最適化手法では設計が不可能とされていた3枚以上のレンズ系の設計自動化に成功した.本研究の成果は100年以上の歴史のある光学設計の分野にブレークスルーをもたらすものと産業界からも高く評価されている.
