摘要

The port operational plan which is optimized before the vessel arrives tends to be disrupted by some uncertainties. And the pre-arranged scheduling plan will be not optimal or even infeasible. In this paper, we focus on the integrated berth and quay crane allocation under disruption. First, an initial allocation model is formulated without taking account of the disruption. Second, a simulation-based strategy is proposed to deal with disruptions. Vessels' berthing times and berthing positions are constrained within stable modes which are extracted through multiple disruption simulations. Under these constraints, a mixed integer linear programming model is presented to solve the integrated berth and quay crane allocation problem. Furthermore, an efficient method is presented to determine the specific quay cranes which serve a vessel. Additionally, four experimental scenarios are designed and conducted on several test instances to validate the performance of the proposed strategy. This strategy proves to be viable. It not only better maintains the stability of the initial scheduling plan but also prevents excessive use of port resources.
