作为集装箱港口非常重要的资源,泊位和岸桥的合理分派与调度可以提高集装箱港口的作业效率。集装箱港口泊位和岸桥的集成分配问题,是为到达集装箱港口的船舶安排最佳停靠泊位、停靠时间与作业岸桥数。考虑连续泊位的泊位分配,以最小化偏离偏好泊位的泊位数和船舶在港停留时间为目标,建立基于偏好泊位的泊位和岸桥集成分配问题的0-1混合整数规划模型;研究船舶停靠不同偏好泊位对港口运营成本、岸桥作业成本的影响,分析偏好泊位惩罚成本的设置给船舶到港时间与离港时间带来的影响。通过仿真分析,得到考虑偏好泊位的泊位和岸桥集成分派计划,拓宽了泊位分配的研究,为港口运营提供了泊位分配的管理建议。
As the most important resources in port,berths and quay-cranes that are optimally allocated and scheduled can improve the operate efficiency of container port. The berth-crane allocation problem is to arrange the best berthing position,dwelling time and the numbers of operating quay cranes for vessels calling for services in the container port. Considering the continuous berth allocation problem,a model of 0- 1 mixed integer linear programming of berth-cranes allocated was proposed based on preference berthing position. The goal of the model is to minimize the differences between the preferences berthing position and berthing position and the length of the stay time in the terminal for all vessels. The impacts of port operating costs and quay-cranes operating costs caused by vessel berthing in differ preference berthing position,the time of vessel arriving and departing by differ preference berthing position penalties were investigated. Through simulation analysis,a scheme of berth-crane integrate allocation based on the preference berthing position was developed.Our work broadens the research area of berth allocation and prosides managerialt recommendations for port operation in berth allocation.
