考虑供应能力不确定性的物流服务供应链协调

为解决供应能力不确定下物流服务供应链协调问题,考虑了由单个物流服务提供商与单个物流服务集成商构成两级供应链,分别研究了固定需求与随机需求下具有供应能力随机性的集中协调与分散协调的决策模型,提出了一种补偿契约机制可实现物流服务供应链系统协调,且固定需求与随机需求下补偿契约的参数相同。契约参数值与需求大小无关,与价格、成本和供应能力不确性有关,并通过算例验证了补偿契约协调的有效性。

Coordination of Logistics Service Supply Chain under Uncertain Supply Capacity

Focusing on the coordinating problem of logistics service supply chain under uncertain supply capacity,this paper offers a study of the two-echelon supply chain consisting of a single logistics service integrator and a single logistics service provider.The study covers the supply chain centralized and decentralized decision model with stochastic supply capacity under deterministic and stochastic demand.It proposes that a pay-back contract can coordinate logistics service supply chain,and the parameters of such contract are the same under deterministic and stochastic demand,which is independent of demand but depends on the price,cost,and the uncertainty of supply capacity.A numerical experiment is presented to illustrate the availability of logistics service supply chain coordination with pay back contract.
