A Zero-blockage based Scheduling for Import Containers Pickup Operations at Container Terminal Yards

Abstract

In container terminals (CTs), containers are stacked above each other due to the limited yard area space used for storing the containers. External trucks usually submit appointment requests to pick up their import containers from the CT. However, some containers are not on the top stack and are blocked by other containers when trucks arrive at the terminal yard. Resolving this blockage requires relocating all containers above the targeted container. This non-value-added operation reduces the yard crane utilization and increases the service of external trucks. This paper studies the appointment scheduling for picking up containers, considering the container stacking sequence in the yard. We propose a scheduling method for container pickup appointments to avoid container blockages. An IP model is developed to minimize shifting appointment times for picking up import containers from its preferable pickup time windows. The performance of the developed model is investigated by solving some numerical instances. In addition, further analyses are performed to study the effect of container blocking on appointment scheduling.
