Mixed-Integer Linear Programming Model for the Simultaneous Unloading and Loading Processes in a Maritime Port

This paper discusses the jointly quay crane and yard truck scheduling problems (QCYTSP) with unloading and loading containers from/to vessel(s) in the same time. Yard trucks transport the containers to/from yard locations with all containers that are homogeneous. We propose a mixed integer linear programming model to solve the scheduling problem. We consider in this study, the quay crane interference, containers precedence and safety margin. The main objective is to minimize the total completion time of the vessels.
