MULTI-OBJECTIVE OPTIMIZATION FOR SIMULTANEOUS BERTH ALLOCATION AND CRANE SCHEDULING PROBLEM
Port management is often faced with many challenging problems that require the decision makers to consider numerous issues all at a time. Involvement of multiple parties in the activities associated with container terminal operations makes the port management problem even more complex. The presence of such complications necessitates the use of a decision support tool.
In this study, we propose a decision support tool for the simultaneous berth allocation and crane scheduling problem considering two objectives that needs to be satisfied. We first extend the literature by better reflecting practical considerations. We then formulate this problem by bi-objective integer programming namely, the objectives of minimizing the total service time and cost of crane setups. To solve the problem we follow an epsilon-constraint method based solution algorithm to acquire the nondominated berth-crane assignments and schedules as Pareto optimal frontier. The decision makers may use the obtained optimal Pareto frontier as a decision-aid tool. With this multi-solution approach, decision maker is offered the flexibility of adjusting the balance within conflicting objectives.
