Research on storage space allocation model of containers in container yard based on mixture storage

With the development of containerization, the requirement for operations optimization in container terminals has become prevalent and necessary. How to improve the efficiency of container yard and yard handling system is really an important subject for container terminals to tackle with. In this paper, a systematic method of container yard is proposed in order to solve both storage space allocation problem and yard crane scheduling problem. Based on mixture storage status of container yard, a mix-integer programming model, which considers various constraints related to operations of yard cranes and storage space allocation rules of yard blocks, is developed. Finally, numerical experiments are conduced to valid this model.
