• Environmental challenge of vehicle dispatching in marine container drayage

  Etsuko Nishimura, Stratos Papadimitriou, Koichi Shintani, Akio Imai

  Abstract In marine container drayage (CD), which refers to the transport of goods over a short distance, empty containers (ECs) are required to be transported long distances between a terminal and a shipper/consignee by conventional transportation. This causes truck traffic congestion in harbor districts that increases CO₂ emissions (CO₂EM). This study addresses the vehicle dispatch problem with respect to the environmental impact of marine CD, considering the tractor dwell time is long at the customer site due to cumbersome container loading/unloading (L/U). We model this problem as an extended version of the vehicle routing problem with precedence constraints to minimize the total CO₂ weighted travel distance. To improve CD operation in long L/U time, we propose a new practice for CD operations. Additionally, we develop a mixed integer programing model (MIP) for the new practice representation, and propose a Simulated Annealing (SA) based heuristic approach to solving the new practice instance. By implementing our proposed new operation, in a long L/U time, the CO₂EM, EC move and number of tractors required can also be reduced by allowing uncoupled tractor move.

• Economic benefits of deploying foldable containers: Reducing bunker and container management costs in a multi-port shipping network

  Koichi SHINTANI, Etsuko NISHIMURA, Akio IMAI

  This study seeks to explore the effectiveness of employing foldable containers (FLDs) in liner shipping to reduce relocation and the empty containers and bunker costs (BCs) associated with ship operations. This resolves a minimum-cost multi-commodity network flow problem by optimizing container fleet size and empty container relocation in a multi-port shipping service network. Port handling time and sailing speed provided by obtained optimal solutions enable the determination of ship BCs as a secondary step. The numerical experiments demonstrate the comparative effect of FLDs against standard ones on the reduction of the costs of empty containers and containership bunker oil.

• Impact of Partitioning Arrangements and Rush-hour Traffic on Quay Space Utilization

  西村 悦子, 天野 慎太郎, 今井 昭夫

  In order to use the quay space efficiently, we address various cases of partitioning arrangement in a given quay space operated by multiple units of one-berth, one unit of multiple-berth, and multiple units of medium and small sizes consisted of one or more berths. In this paper, we investigate the impact of partitioning arrangements and rush-hour traffic on quay space utilization. From the computational results, the arrangements operated by one units of large-size and multiple units of medium-size outperform those done by the others, in most cases. However, it is clear that total service times depend on ship arrival pattern, ship service distribution and rush-hour traffic.

  The efficiency of a container transport system primarily depends on the ship scheduling, which is regarded as a complex dynamic application. Therefore, this paper is concerned to ship stowage problem while satisfying the ship safety in her voyage at a number of ports-of-call, which obviously determines the economic performance of the liner shipping companies. When the ship goes to multiple ports-of-call, the stowage problem has been considered at each port in her routine. The problem is formulated as a mixed integer programming and a heuristic is developed to solve it.

• An investigation into effectiveness of container arrangements on optimizing a containership stowage plan

  Nguyen Thanh Thuy, Etsuko Nishimura, Akio Imai

  Container is a standard in worldwide transportation method, which is capable of being moved by sea, road or rail with relative simplicity. Due to the continuously increasing container trade, many container terminals as well as liner shipping companies are presently frustrating to shorten the turnaround time of a ship for financial savings. Therefore, any methods to improve the containership stowage process would be significant. This paper examines the effectiveness of container arrangements in order to evaluate how to optimize the stowage plan, which was established at the present port and associated with the unloading plan at next port. The efficient of the ship stowage plan is evaluated by the minimum number of rehandled container required and the maximum value of ship stability obtained during to trip from the present port to the next port. The genetic algorithm is employed as a heuristic for the approximately optimized solutions and the validation of the proposed approach is performed with some computational experiments.

• Determining containership loading problem on the basis of an adopted number of handling cranes

  Nguyen Thanh Thuy, Etsuko Nishimura, Akio Imai

  Faster turnaround time of vessels is one of paramount factors in a container terminal for assuring competitive advantage in the shipping industry, which can be achieved by efficient handling process of vessels, especially the associated loading plan in the loading sequence. This paper deals with the ship loading problem regarding to the number of cranes to be used in a loading process while keeping reasonable ship stability. In order to preserve the ship stability, some heavier containers may be stowed at the bottom of ship holds. When those containers are stacked below others on a yard container block which are withdrawn later, it may required a number of rehandles when they are retrieved from the blocks. The efficient of loading process is evaluated by the minimum number of container rehandles required. To solve this problem, a mix integer programming is formulated. The genetic algorithm, which is widely applied for a plenty of practical mathematical programming, is employed as a heuristic for the nearly optimized solutions and a wide variety of numerical experiments was made where solutions by this problem are useful and applicable in practice.

• A genetic algorithm based approach to constructing container shipping networks with empty container repositioning among calling ports

  Koichi Shintani, Akio Imai, Etsuko Nishimura

  This paper addresses the design of container liner shipping service networks by explicitly taking into account empty container repositioning and container fleet size. Two key and interrelated issues of deployments of ships and containers are usually treated separately by most existing studies on shipping network design. In this paper, both issues are considered simultaneously. The problem is formulated as a two-stage problem: the upper-problem being formulated as a Knapsack problem and the lower-problem as a Flow problem. A genetic algorithm based heuristic is developed for the problem. Through a number of numerical experiments that were conducted it was shown that the problem considering empty container repositioning provides a more insightful solution than the one without.

• Estimating containership handling times in a container terminal

  Etsuko Nishimura, Akio Imai, Bai Zhao, Hitoshi Kaneko

  Port charges in Japan have been consistently higher than those in other major hubs over several years. Part of the increased costs is the result of overcapitalization to the port for the relatively small cargo volume. For terminal efficiency, we have already investigated the dynamic berth allocation in a multi-user terminal, where the handling time of a ship is assumed to depend on its quay location and container stock location. However, the time is given in the berth allocation model without considering sophisticated operational aspects in the terminal. In this study, we construct models that estimate the ship handling time.

• An analysis on vehicle speed in urban streets by using the traffic information

  IMAI AKIO, OKAYAMA MASATO, NISHIMURA ETSUKO, ITO YASUHISA

  従来より、配送ルート決定のための取引先間の旅行時間を簡便に推定できる方法について検討した研究があり、重回帰モデルによって旅行時間に影響を与える要因について考察している。
  一般に、旅行時間は交通量の違いによる走行速度の変化によって影響を受けると考えられるが、重回帰分析のような簡便なモデルに対して速度変化を変数に取り入れることは非常に困難である。
  そのため、既往の研究では、速度変動による旅行時間の影響を「朝」、「昼」、「夕方」といった時間帯で代用している。しかしながら、その妥当性について検討していない。
  そこで本研究では、道路交通情報より得られた所要時間を用いて、交通量変動に代替するものとして時間帯や曜日、週変動などを考え、それらと走行速度の変動との関係について分析する。
  分析の結果、道路の種類や時間帯によって走行速度への影響は大きく、週や曜日による影響

  本研究の目的は，折りたたみコンテナ(以下，折りコンと呼ぶ)の導入が空コンテナの回送を減らすだけでなく，コンテナ船の燃料油費を低減させるかどうかを数理的手法により検証することである．折りコンとは，空荷のときに折りたたむことができ，それら一定個数を高さ方向に結束すると，元のコンテナ1個と同一寸法となるコンテナのことである．現在のところ，折りコンは市場において本格的導入にはいたっていない． コンテナ船の運航からの観点で折りコン導入のメリットを考えた場合，一度に複数の空コンを荷役できるので，港での荷役時間を短縮できる見込みがあるところにある．その荷役時間の短縮分は，航海時間へ転換でき，減速運航さらには燃料油費の低減に寄与する．世界中を行き来するすべてのコンテナ船にこの減速効果がもたらされればその効果は甚大である．このことより，折りコンの経済性を評価するにあたり，コンテナ船の燃料油費の低減効果も加味する必要がある． 当該年度では，大陸間の海上コンテナ輸送における空コンテナ流動モデルを構築した．そのモデルは，①標準コンテナ(以下，標準コンと呼ぶ)のみ，②標準コンと折りコンの混同使用，③折りコンのみ，の3通りのコンテナ保有構成を想定する．最適化計算により，最適コンテナフローを決定する．本研究では，上述のモデルを用いた数値実験によって求まった最適解(コンテナフロー)を解析し，各港で荷役されるコンテナ数から荷役時間を求め，さらに平均速力と燃料油費を算出し，①～③を比較する． 数値実験の結果，②が他のフリート構成よりもコンテナ管理費用と燃料油費の合計費用を最も小さくする可能性があることがわかった．

  To be advanced the decision making of container terminal operation, the system development is often focused on. The terminal location, terminal configuration and resource behavior complicate decision making. This study focuses on containers arriving from the land side to a marine container terminal as one of resources, we developed a mathematical model to evaluate the terminal layout with container-to-yard arrangement. By treating containers as a group and arranging time unit, it is possible to represent relatively simple mathematical formulation. From the computational results, this study analyzes the effect on service time by terminal configuration, ship arrival pattern, and external truck arrival pattern, number of container handled etc.

  Most merchandized cargo traffic of the world trade is sea-borne and air-borne with efficient use of containers. The global economy is so complex that trade is in most cases imbalanced, resulting in an enormous volume of empty container repositioning. Due to sea- and air-containers with design features fitting to their transportation modes, each type of container is repositioned by its own transportation mode. Assuming special sea- and air-container concepts with folding function, both of which can be repositioned by any of both transportation modes for empty repositioning cost saving; this study established an evaluation system to examine how this kind of the so-called hybrid empty container repositioning concept works out.

  This study examined the economic viability of the hybrid containers. The problem was separated into two container management problems, namely, foldable containers and combinable containers, due to their complicated model structure. They were formulated as a mixed integer programming model and an analytical model. This study found that, under certain conditions, foldable containers and combinable containers can significantly reduce the empty container repositioning cost and the container fleet cost, respectively. However, modeling the problem of hybrid containers remains critical to achieve real benefits in using hybrid containers.

  Some of the major overseas airports adopt the peak-load pricing for the tariff airlines pay. Due to this pricing concept, airline demands of using an airport do not likely intensify during a specific period of time. As far as the seaport is concerned, most of the calling ships tend to call at a port (container terminal) during a specific time mainly due to the cargo owners' preference. Introducing the pricing concept for the port like the airport, this study has developed an optimal berth scheduling optimization model to minimize the total turnaround time of calling ships by spreading the calling demands over the predetermined planning horizon.

  Containerships are getting larger and larger, involves the handling equipment requires advanced technology in marine container terminals. As one of some ideas, multiple types of handling equipment are often operated in a specific terminal. In this project, we propose the way to operate multiple types of handling equipment simultaneously at a specific terminal and also to find the situation effectively being operated. To be concrete, we investigated terminals that multiple types of equipment have already operated in order to find features of those terminals and machinery characteristics. After that, we developed the mathematical model with parameters and constraints such as terminal configuration and container block layout. In order to find effectively feasible solutions of the model, we developed the algorithm by using metaheuristics. From computational results, it is clear that one type of equipment outperforms multiple types of equipment, in small size problem with optimal solution.

  Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Young Scientists (B), Grant-in-Aid for Young Scientists (B), Kobe University, 2011 - 2012

  As the containerships have become larger, the container terminals in foreign counties come up with various ideas to make the layout in order to be smoothly operated. There are many rectangular container terminals in the world. However, there are also polygonal terminals in foreign counties. In the rectangular terminal, one aisle between container blocks is located in same interval as others along the quay length, and the size of one container block is also same as others. In the polygonal terminal, the aisle between container blocks located and the size of container block are dependent on the shape and the region and so on. Therefore, this study proposes the algorithm for optimizingthe aisle location between container blocks and the container arrangement in yard area with a shape given in advance.

  We focus on how detail the model is expressed and what kind of method the type of handling equipment is considered in order to estimate the handling times spent for ship berthing and quay crane working. For the container storage arrangement, we relax some constraints, and develop the algorithm for solve the problem. For the estimation of handling time, we develop the model to simulate the terminal by handling equipments, and also develop the multiple regression model to estimate the handling time by using parameters and handling time obtained at numerical experiments. From the numerical results of storage arrangement with handling time data by machine type, it is clear that most suitable type of handling equipment depends on port congestion.

  1.研究目的 超大型船が規模の経済性を発揮するには、少数のハブ港のみを寄港すると予想され、ハブでの荷役貨物量は膨大になる。これに対処するために、最新のターミナルでは自動化・無人化のシステムが導入されているが、現在ソフト面で重要視されるのは、文書の電子化、情報の共有化のみであり、マシンの動きやヤード内コンテナ配置における意思決定には自動化が進んでおらず、人間の経験に依存している。そこで本研究では、超大型船対応港湾において取扱いの中心であるトランシップ貨物を対象に、コンテナ配置計画サポートシステムを構築する。 2.研究結果 (1)モデル化の範囲の同定:コンテナの重量区分、最終仕向け地別、コンテナ自体のサイズ・種類別で配置計画は実施され、現状においては荷主の過去の利用実績から各種情報を予測し、システムにはあくまでオペレータによって決定した位置情報の管理コンピュータソフトウエアに依存している。超大型コンテナ船対応のターミナルではトランシップ貨物が多く占め、従来型では輸出入コンテナが主となる。両者で大きく異なるのが、貨物の到着のタイミングであり、本問題では超大型船の到着として扱うことができる。(2)コンテナ配置の最適化における評価尺度の同定:調査結果を元に、モデルはコンテナ重量区分と仕向け地によるコンテナグループ単位で意思決定するもの(モデルA)、フィーダー船ごとに意思決定するもの(モデルB)を考案した。(3)コンテナ配置問題のモデル化:まずモデルAをRTGの移動距離最小化問題として扱うことにし、モデルBでは全対象船舶の荷役時間最小化として扱った。(4)数値実験の実施と計算結果:まず前者について、学会発表等を通して意見交換を行った結果、研究論文としてみたときに制約が複雑すぎて、今後の発展が期待しにくいとの意見があったため、見方を変えた後者モデルを検討した。両者とも、超大型船のみを優先にしてコンテナ配置位置を決めれば、フィーダー船へのサービスが低下するが、モデルで設定した評価指標および提案した解法を用いれば、フィーダー船の作業時間等延長も抑えられることがわかった。(5)関連研究:ターミナル規模が大きくなるほど、配置計画は複雑になる。また超大型船が寄港するターミナルはマルチユーザ方式が現実的であるため、マルチユーザターミナルの利用実態についても研究成果をまとめた。この結果も本間題の今後の発展に利用できるものである。
