Recovery Berth Allocation And Quay Crane Assignment Considering Transshipment In Container Terminals

In container terminals,operators normally form an initial plan for berth allocation before the arrival of incoming vessels.However,during the real operations,unforeseen incidents(e.g.,delays,equipment breakdowns)happen frequently,which hinder the implementation of initial plans.In response to disruptions,terminal operators usually employ an experience-based strategy for berth allocation recovery.However,this practice may not work well in challenging situations,especially when extensive transshipment operations need to be conducted,and the berthing for mother and feeder vessels should be coordinated.This paper studies the disruption recovery problem for berth allocation in transshipment terminals,and develops decision support tools for terminal operators.A mixed integer linear programming model is developed to adjust the original plan with the objective of minimizing recovery cost caused by deviations from the original plan.Quay crane assignment decision is also taken into account during disruption recovery.Transshipment connections between correlated feeder and mother vessels are also considered specifically in order to reduce the missing of transshipment connection opportunities.A heuristic method based on Squeaky Wheel Optimization is devised to find nearoptimal solutions within short computational times.Extensive numerical experiments validate the effectiveness and efficiency of the proposed solution method,and show the practical benefit from incorporating transshipment consideration when rescheduling berth allocation.In addition to recovery strategy,proactive strategy is also an important part of disruption management in container terminals.Therefore,this paper explores the proactive berth allocation problem in order to minimize the cost of original schedule and the expectation of recovery cost under different disruption scenarios simultaneously.Thus,the robust berth allocation model is formulated and computational experiments are designed to verify the effectiveness of the proposed model.In conclusion,this paper explores the disruption management in container terminals from reactive and proactive perspective based on the identification of disruption factors,aiming to provide reasonable and effective decision-making strategies for container terminals in response to disruption.
