基于援助合同的供应链应急管理

研究由1个供应商和1个零售商组成的供应链,在供应商发生突发事件的情况下,零售商为供应商提供援助,以协调该供应链.建立了按时间顺序研究突发事件的两阶段模型,证明了可以协调供应链的援助合同应满足:零售商提供的援助数量对供应商恢复时间的偏导数为零售商订单拖欠成本的相反数,并且援助数量对供应商初始预防措施的偏导数为0.

Aid Contract-Based Disruption Management in Supply Chain

By taking a supply chain consisting of one supplier and one retailer as a research object,an aid contract offered by the retailer was used to coordinate the supply chain when the supplier is disrupted.Based on the time sequence of the disruption,a two-stage model was set up for the disruption.The research show that to coordinate the disrupted supply chain,the aid contract must satisfy the following conditions: the partial derivative of aid quantity offered by the retailer to the recovery time of the supplier is the opposite number of retailer's backorder cost,and the partial derivative of the aid quantity to the supplier's preventive measures is zero.
