在集装箱海铁联运运营管理中,随机需求环境下集装箱海铁联运的动态定价是影响联运经营人的经营效益和竞争力的重要决策因素.基于收益管理理论,结合集装箱海铁联运的经营和组织特点,以协议销售和自由销售的差异化定价为切入点,分两阶段建立了单起讫点间集装箱海铁联运动态定价和箱位分配综合优化模型.第一阶段为基于协议销售的箱位分配模型,第二阶段为基于自由销售的动态定价模型.针对箱位分配模型的随机特征和动态定价模型统计量的误差特性,分别运用机会约束和稳健优化方法求解.通过算例验证了上述模型与算法的适用性和有效性.
Dynamic pricing problem under uncertain conditions has significant impacts on the benefit and competitiveness of a Muhimodal Transport Operator (MTO). Based on revenue management theory and features of container sea-rail intermodal transport, this paper established a two-stage optimal model which integrated dynamic pricing and slot allocation on single orlgin-destination line. The first stage was proposed by considering long-term slot allocation in contract market, and the second stage was proposed by considering the dynamic pricing in free market. Due to the demand uncertainty and the statistic error characteristic, the method of chance constrained programming and a robust optimization model were employd to solve the models respectively. The simulation results have shown that the models and algorithms are feasible and effective.
