Transportation problem is an optimization problem. In general, it was studied under random or uncertain condition. Considering the recent complexity, it is not enough to make should be a perfect transportation plan only based on. Usually, there is not only uncertainty but also randomness in many systems. In this paper, the aim is to investigate a transportation problem under uncertain and rando…
The approach assumes a basic knowledge of programming, equivalent to that presented in computer programming. This knowledge is needed to understand how sequences required for software are built and how the book incorporates them in subroutines to make larger routines and, finally, to make a complete system. The book provides basic information for a programmer entering the software field. It wil…
Container terminals are essential intermodal interfaces in the global transportation network. Efficient container handling at terminals is important in reducing transportation costs and keeping shipping schedules. In this paper, we study the storage space allocation problem in the storage yards of terminals. This problem is related to all the resources in terminal operations, including quay …
The enormous potential of combined transport (rail-road) makes rail the main alternative to the transport of freight by road in the Europe. Unfortunately, the European railway network is strongly fragmented, having different bottleneck points. This paper presents research that centers on the transhipment tasks in the Port Bou terminal. This terminal is a bottleneck point because of the differen…
Yard planning is essential for efficient operations in container terminals, especially for ports with limited storage space. To improve the utilisation of space and the efficiency of container handling in a terminal, operators require flexible yard space planning strategies to manage job workloads and yard-to-berth transportation costs. In previous studies, the inter-related decision making pro…
This study is motivated by the practice of large iron and steel companies, which have steady and heavy demands for bulk raw materials such as iron ore, coal, limestone and so on. These materials are usually transported to a bulk cargo terminal by ships (or to a station by trains). Once discharged, they are moved to and stored in bulk material stock yard, waiting for retrieval for production use…
A methodology is proposed to determine the storage location of an arriving export container considering its weight. We consider the con®guration of the container stack and the weight distribution of containers in the yard-bay. A dynamic programming model is formulated to determine the storage location to minimize the number of relocation movements expected for the loading operation. We also de…

This paper studies a storage yard management problem in a transshipment hub where the loading and unloading activities are both heavy and concentrated. In order to reduce the number of reshuffles, which helps to reduce the vessel turnaround time, the port operator uses the consignment strategy to group export and transshipment containers according to their destination vessel. To reduce the pote…
This paper provides an integrated solution for two common processes in a container seaport: namely, the Berth Allocation Process (BAP) and the Crane Scheduling Process (QCSP). These are formulated through a Bi-Level Programming (BLP) approach, which is used to characterize the highly interrelated relationships between the two processes and simultaneously, identify an integrated solution for bot…
This paper addresses two coordination problems that exist in the waterborne transport in large seaports, the long time of stay of inland vessels and insufficient terminal and quay crane planning with respect to their sailing schedules. A novel coordination model is proposed and tackled using logic-based Benders decomposition and Large NeighborhoodSearch. In addition, a closed-loop perspective i…
In today’s highly competitive global environment, companies are forced to compete on price and delivery speed. Global logistics transportation presents some special challenges and issues for business organizations, and these issues differ from those posed by domestic logistics transportation. This study considers road transportation problems between two countries. A mixed-integer programming …
Seaports are exposed to various uncertain disasters caused by natural or human factors, which have multi-dimensional impacts on the economy. Retrofit appears as one of the effective mitigation methods to protect the seaport network and to reduce the post-disaster loss in the port management engineering. The post-disaster loss is quantified by replacement or repair cost of the structural damage …
Today’s managers are turning to the functions of the supply chain to improve margins and gain competitive advantage. The explosion of the Internet and other e-business technologies has made real-time, online communication throughout the entire supply chain a reality. Electronic supply chain management (eSCM) is a reference to the supply chain that is structured via electronic technology-enabl…
Examines the interdependence between facility location, transportation and inventory issues in a distribution network design problem. Management of inventories, determination of transportation policy, and location of plants and distribution centers are normally carried out by different groups of people in an organization. These activities interact, however, when the transportation is used to re…
This paper studies a yard storage allocation problem in a transshipment hub where there is a great number of loading and unloading activities. The primary challenge is to efficiently shift containers between the vessels and the storage area so that reshuffling and traffic congestion is minimized. In particular, to reduce reshuffling, a consignment strategy is used. This strategy groups unloaded…

Unlike the prevalent optimization techniques, this paper proposes an integrated approach which considers both quantitative and qualitative facto…
Berth planning plays an important role in improving the efficiency of a container terminal. This study focuses on the berth template problem (BTP), which determines the berthing windows of the calling ships within a planning horizon (e.g. a week) in a cyclical way. As a mid-term tactical decision problem, BTP provides the decision support for a terminal operator to negotiate the contracts with …
