Abstract

A container ship is a vessel designed to carry containers and is now the main mode of sea freight in commercial ports. It is an integral part of world trade. Upon arrival at a seaport, the container ship stays inactive at the dock for the duration of loading and unloading operations. Handling operators at the port terminal are provided with a schedule showing the dates of loading and unloading of containers, as well as their locations in the container ship. An optimal location for a container in a container ship is very important for companies because this operation reduces transport costs. In this work, the authors propose an approach to solve the container placement problem through the description of a decision model that allows solving and optimizing the available storage space on a container ship. The objective of this work is to find the best location for all types of containers in the container ship based on the multi-criteria methods Electre III (elimination and choice expressing reality); in this contribution, four criteria are used: the container destination, the container weight, the departure date of a container, and the container type.

The Container Ship Loading Problem

For many years, container loading has been a real problem in the maritime environment.

The handling of import or export containers leads to a lot of unnecessary movement or a reshuffling, consisting of unstacking several containers to reach a specific container placed under the bay.

Figure 1 shows the retrieval of a container from the middle of the bay, to retrieve container B, it is necessary to first remove container C, then retrieve container B and finally put container C back in the row. So, actions 1 2 and 5 6 are unnecessary displacements.

So, the problem that arises is how to determine the best storage of any containers to minimize unnecessary movements.
