需求随机偏差下带有主从零售商的供应链协调

研究了确定环境下带有主从零售商的供应链协调的基本模型,提出了应急环境下当需求偏差随机发生时集权和分权供应链的最优决策.证明了无论需求随机偏差存在与否都可以运用线性数量折扣合同使得供应链有效达到协调,并相应给出了最优批发单价、最优线性折扣率和转移支付的范围.最后对最优售价、最优总订货量和最优批发单价随需求偏差幅度及其概率的变化进行了仿真分析.

Supply chain coordination with dominant retailer and fringe retailer under the stochastic disruption of the demand

The basic model on the supply chain coordination with one dominant retailer and one fringe retailer is studied
under the deterministic environment, while the optimal policies in the integrated and decentralized supply chains are proposed when the demand disruption happens randomly under the emergency environment. It is proved that linear quantity discount contract can be used to coordinate supply chain efficiently whether the stochastic disruption of the demand exists or not. Correspondingly the optimal per-unit wholesale price, the optimal linear discount slope and the scope of transfer payment are given. Finally, it are simulated and analyzed that the optimal retail price, the optimal total order quantity and the optimal per-unit wholesale price change with the demand disruption magnitude and its probability.
