基于收益管理的班轮联盟舱位互换与分配优化

运用收益管理原理方法,研究了联盟条件下班轮公司舱位互换与分配问题,构建了综合考虑班轮联盟多条航线、不同种类和不同尺寸的集装箱等因素的舱位互换与分配随机优化共赢模型,运用机会约束方法加以求解,算例分析验证了模型和算法的适用性和有效性,结果表明舱位互换与分配优化可以明显地提高班轮联盟的总收益,联盟内舱位互换与分配数量及其总收益与合同客户需求量呈负相关、与现货市场需求量呈正相关,从而可为班轮公司制定舱位互换与分配策略提供科学的决策参考.

Optimization of slot mutual exchange and allocation based on revenue management in liner alliance

Based on the principle and practice of revenue management, this paper studied the slot mutual exchange and allocation problem in liner alliances. A win-win slot mutual exchange and allocation stochastic programming model was established with regard to the factors of multi-routes operated by the liner alliance, as well as the different size and different type of containers. Then, the chance constraint approach was employed to solve the problem. The result of numerical example shows that the established model and its algorithm are feasible and effective. It illustrates that the optimization of slot mutual exchange and allocation could improve the total revenue in liner alliances significantly. Furthermore, it also indicates that the amount of slot mutual exchange and allocation as well as the total revenue are negative to the quantities of contract customer demand and positive to the quantities of demand on spot market. Therefore, it could provide a scientific decision reference on slot mutual exchange and allocation for liners.
