This paper presents a holistic analysis for the network design problem of the intermodal liner shipping system. Existing methods for liner shipping network design mainly deal with port-to-port demand. However, most of the demand has inland origins and/or destinations. Thus, it is necessary to cope with inland origin-destination (OD) pairs involving a change in transport mode from inland transpo...
The aim of the study was to analyze scientific views on definition liner shipping at various stages its development. For this, literary sources for more than a hundred years research this issue were analyzed. analysis emphasizes lack systemic studies and approach concept in question. As result study, development are presented main characteristic features given, boundaries established. resulting...
We solve an important problem for the liner shipping industry called the Liner Shipping Fleet Repositioning Problem (LSFRP). The LSFRP poses a large financial burden on liner shipping firms. During repositioning, vessels are moved between services in a liner shipping network. Shippers wish to reposition vessels as cheaply as possible without disrupting the cargo flows of the network. The LSFRP ...
Late Acceptance Hill Climbing (LAHC) has been shown to be an effective local search method for several types of optimization problems, such as on certain types of scheduling problems as well as the traveling salesman problem. We apply LAHC to a central problem in the liner shipping industry, the Liner Shipping Fleet Repositioning Problem (LSFRP). The LSFRP involves the movement of vessels betwe...
The Liner Shipping Fleet Repositioning Problem (LSFRP) poses a large financial burden on liner shipping firms. During repositioning, vessels are moved between services in a liner shipping network. The LSFRP is characterized by chains of interacting activities, many of which have costs that are a function of their duration; for example, sailing slowly between two ports is cheaper than sailing qu...
Concerning the implementation of marketing philosophies and policies in shipping companies no extensive research has been made up to now. This article presents the application of marketing philosophies and policies to the companies, which are activated in merchant (tramp and liner) and passenger shipping. The emphasis is given to the merchant shipping companies due to the fact that the passenge...
We solve the liner shipping fleet repositioning problem (LSFRP), a key problem in the liner shipping industry, using a hybrid reactive tabu search and simulated annealing algorithm in combination with novel local search neighborhoods. Liner carriers reposition vessels between services in order to add, remove or modify services in their network. Repositioning vessels costs between hundreds of th...
Taking into account increasing volumes of the international seaborne trade, liner shipping companies have to ensure efficiency of their operations in order to remain competitive. The bunker consumption cost constitutes a substantial portion of the total vessel operating cost and directly affects revenues of liner shipping companies. “Slow steaming” became a common strategy among ocean carriers ...
We will gives an overview of several decision problem encountered in liner shipping. We will cover problems on the strategic, tactical and operational planning levels as well as problems that can be considered at two planning levels simultaneously. Furthermore, we will shortly discuss some related problems in terminals, geographical bottlenecks for container ships and provide an overview of ope...
A classification scheme for routing and scheduling problems in liner shipping is developed and subsequently used to classify existing literature on the subject. Based on the classification the articles are grouped, and the main characteristics of each group and article are described. The grouping may serve as a catalyst towards developing a model or a group of models that covers the main proble...
