基于Credit期权的集群式供应链采购模型及算法分析

集群式供应链是以产业集群为运作平台的供应链系统。本文先在单供应商-单采购商采购模型的基础上，建立了多供应商-多采购商的集群式供应链分散式采购模型。在模型中通过采用柔性周期和Credit期权策略，构建了适合多频次、小批量、柔性、信任等特征的集群式供应链多供应商-多采购商Credit期权联合采购模型，并设计出针对模型的Enumeration算法。最后，通过算例分析了集群供应链Credit期权联合采购模型有效性。

Cluster Supply Chain Replenishment Model and Algorithm with Credit Option

Cluster supply chain is a system operating on the platform of industrial cluster. In this paper, a multi-vendor multi-buyer decentralized replenishment model is explored based on the single-vendor single-buyer model at first. Then by incorporating the policy of flexible ordering intervals and credit option, a multi-vendor multi-buyer joint replenishment model is proposed with credit option which will meet the purchasing features of high frequency, small batch, flexibility and dependence nicely in the cluster supply chain, and the corresponding enumeration algorithm is provided. Lastly, by numerical analyses, the efficiency of the joint replenishment is rerified. According to the sensitive analyses, how holding cost and ordering intervals affect the optimal delayed payment period as well as the cost is also studied.
