Abstract
The marine container terminal is operated by various types of handling equipment. The relevant terminal layout is suitable to the equipment type. We focus on the type of handling equipment assigned to the terminals in the world. We consider the effect of equipment type and layout on the container arrangement. The differences among equipment types are following: (1) the service time depends on the path location for yard trailer or straddle carrier movement, (2) the total capacity of container storage is determined by the size and mobility for equipment. Therefore, we set two objective functions as minimizing the total service time and minimizing the space utilization to this problem. We obtain the solution set consisted by multiple non-dominated solutions. In order to compare among types of handling equipment, we find the true Pareto set from the combined set by the solutions obtained in the terminal which each equipment type is assigned. We find which equipment type does the non-dominated solution included in the true Pareto obtains from. From the computational results, the non-dominated solutions included in the true Pareto set are independent on the ship arrival pattern and the pattern of ship berthing locations, those are more solutions obtained by RTG. And among them, the service levels with around half of solutions obtained by RTG are equal to those with solutions obtained by RMG. However, there is a little solution obtained by SC in the true Pareto set.
