两种不同承诺时间下运输服务供应链决策

由于需求的不确定性，托运人的承诺时间会对运输服务供应链的决策产生影响. 因此，本文考虑在延迟承诺和提前承诺两种承诺时间下，基于运价分别为外部定价和承运人定价两种情况，建立了运输服务供应链中承运人的运输价格和托运人的托运量优化决策模型，并分别对延迟承诺和提前承诺、整体决策和单独决策时的优化结果进行比较分析，从而为运输服务供应链决策提供有效的参考价值. 通过研究得出，整体决策时运输服务供应链的收益总是大于单独决策时的收益；承运人的运价也对托运人的承诺时间产生影响，在不同的运价下，提早承诺和延迟承诺的优越性不同.

Decision Making in Transportation Service Supply Chain under Two Different Commitment Times

The supplier’s commitment time always influence the decision of the transportation service supply chain when the actual demand is unknown. Considering a delayed commitment and an early commitment, this paper presents decision models to determine the carrier’s transport price and the shipper’s transportation quantity under exogenous price and carrier pricing. The optimal results are compared between the overall decision-making and individual decision-making, delayed commitment and early commitment. It provides references for transportation service supply chain decision-making. It is shown that the profits of the transportation service supply chain under overall decision-making are larger than that under individual decision-making. It also finds that the carrier’s transport price affects the supplier’s commitment time, and the superiority is different between a delayed commitment and an early commitment under different transportation price.
