Unified heuristics to solve routing problem of reverse logistics in sustainab…

A reverse logistics problem, motivated by many real-life applications, is examined where bottles/cans in which products are delivered from a processing depot to customers in one period are available for return to the depot in the following period. The picked-up bottles/cans need to be adjusted in the place of delivery load. This problem is termed as simultaneous delivery and pick-up problem wit…

Quay crane scheduling in container terminals

The problem of scheduling identical quay cranes moving along a common linear rail to handle containers for a ship is studied. The ship has a number of container-stacking compartments called bays, and only one quay crane can work on a bay at the same time. The objective of the scheduling problem is to find the work schedule for each quay crane which minimizes the ship’s stay time in port. Find…

Optimal collaborative transportation service trading in B2B e-commerce logistics

This paper investigates a less-than-truckload carrier collaboration decision-making problem in the e-commerce logistics network. E-commerce less-than-truckload carrier collaboration problem considers multiple logistics service providers (LSPs) forming a collaborative alliance in an e-commerce logistics network. They share their transportation requests and vehicle capabilities to maximise the to…

Integrated Storage Space Allocation and Ship Scheduling Problem in Bulk Cargo…

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…

Hybrid Estimation of Distribution Algorithm for the Quay Crane Scheduling Pro…

The competitiveness of a container terminal is highly conditioned by the time that container vessels spend on it. The proper scheduling of the quay cranes can reduce this time and allows a container terminal to be more attractive to shipping companies. The goal of the Quay Crane Scheduling Problem (QCSP) is to minimize the handling time of the available quay cranes when performing the tasks of …

Heuristic estimation of container stacking and reshuffling operations under t…

This paper addresses a highly researched area, the reshuffling problem in ports, using a newparadigm-modified containership service order in light of credit risk assessment. Container stacking and reshuffling operations can cause ship delays and additional risk. In deep-sea terminals, outbound containers are tightly stacked according to the retrieval sequence. Due to lack of space, terminals st…

An optimization model for storage yard management in transshipment hubs

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…

A general purpose Lagrangian heuristic applied to the train loading problem

In this paper we face the train loading problem (TLP) at seaport terminals by proposing a general purpose Lagrangian heuristic. The TLP consists of assigning import containers to the trains departing from the terminal, maximizing the utilization of trains, minimizing the distance travelled by containers from their locations in the storage area to the wagons, as well as the number of needed unpr…

A simulation based decision support system for logistics management

tThis paper deals with designing and developing a Decision Support System (DSS) that will be able tomanage the flow of goods and the business transactions between a port and a dry port. An integrated DSSarchitecture is proposed and specified and the main components are designed on the basis of simulationand optimization modules. In order to show the use and implementation of the DSS, this work …

A critical-shaking neighborhood search for the yard allocation problem

The yard allocation problem (YAP) is a real-life resource allocation problem faced by the Port of Singapore Authority (PSA). As the problem is NP-hard, we propose an effective meta-heuristic procedure, named critical-shaking neighborhood search. Extensive experiments have shown that the new method can produce higher quality solutions in a much shorter time, as compared with other meta-heuris…

A continuous berth template design model with multiple wharfs

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 …

A heuristic algorithm for yard truck scheduling and storage allocation problems

The yard truck scheduling and the storage allocation are two important decision problems affecting the efficiency of container terminal operations. This paper proposes a novel approach that integrates these two problems into a whole. The objective is to minimize the weighted sum of total delay of requests and the total travel time of yard trucks. Due to the intractability of the proposed proble…

Network design in supply chain management

The distribution function in a supply chain is an important internal service function for any firm, and has been increasingly recognized as playing a strategic role in achieving competitive advantage. This paper proposes improving the distribution function of the supply chain by employing hub‐and‐spoke network designs. Such designs have proven to be effective with third party logistics carr…

A heuristic rule for relocating blocks

One of the most important objectives of the storage and pickup operations in block stacking systems is to minimize the number of relocations during the pickup operation. This study suggests two methods for determining the locations of relocated blocks. First, a branch-and-bound (B&B) algorithm is suggested. Next, a decision rule is proposed by using an estimator for an expected number of additi…

Research into container reshuffling and stacking problems in container termin…

Container stacking and reshuffling are important issues in the management of operations in a container terminal. Minimizing the number of reshuffles can increase productivity of the yard cranes and the efficiency of the terminal. In this research, the authors improve the existing static reshuffling model, develop five effective heuristics, and analyze the performance of these algorithms. A disc…

Sea container terminals: new technologies and OR models

Owing to a rapid growth in world trade and a large increase in the flow of containerized goods, sea container terminals play a vital role in globe-spanning supply chains. Container terminals should be able to handle large ships, with large call sizes within the shortest time possible, and at competitive rates. In response, terminal operators, shipping lines and port authorities are investing in…
