为解决集装箱班轮运输的舱位分配优化问题,运用收益管理和市场细分理论,根据客户的异质性将集装箱班轮运输市场细分为普通客户市场和加急客户市场,利用Prob函数和NORMINV函数计算出多港挂靠航线某航次各航段上加急客户市场应预留的舱位数量以及可以接受普通客户订舱的舱位数量。在此基础上,建立了包含空箱调运问题的舱位分配随机规划模型,设计了相应的算法,算例分析显示了该模型及算法的有效性。
To optimization of slot allocation of container liner shipping the theories of revenue management and market segmentation is applied. The container liner shipping market is divided into general customer segment and rush customer segment according to its heterogeneous aspect. The Prob function and NORMINV function are employed to obtain the amount of preserved slots for each part of the multi-ports route for the rush customer segment and the necessary amount of slots needed for general customer segment. With the priciple, a random programming model for the container slot allocation with the allocation and transport of empty containers is established and its relevant algorithm is designed. Example analysis shows the effectiveness of the model and of the algorithm.
