非对称信息下双渠道供应链应对突发事件协调模型

针对由制造商主导的双渠道供应链,引入双渠道价格敏感系数及竞争系数两个变量,假设零售商的成本信息为私有条件,研究在非对称信息下发生突发事件的双渠道供应链最优应对。研究结果表明,供应链的最优生产量、最优直销价格、批发价格和最优零售价格具有一定的鲁棒性。在非对称情形下,突发事件导致零售商成本在一定范围内扰动时,双渠道供应链的最优生产计划、销售计划可以保持不变。但当零售商的成本扰动超出了一定范围时,则需要通过协调才能使供应链重新达到平衡,实现对突发事件的有效应对。最后,通过数值仿真验证了研究结果。

Emergency Coordination Model for Dual Channel Supply Chain Under Asymmetric Information

The coordination problem of the manufacturer dual channel supply chain was analyzed. Introducing two variables of the dual channel price sensitive coefficient and the competition coefficient, and assuming that the retailer''s cost information is the private condition, the optimal response of a dual channel supply chain on unexpected events under asymmetric information was studied. The results show that the supply chain optimal production quantity, optimal selling price, wholesale price and optimal retail price have certain robustness. In the asymmetric information situation, the emergency causes the cost of the retailer to be disturbed in a certain range, and the optimal production plan of the double channel supply chain can be kept unchanged. But when the cost disturbance of the retailer exceeds a certain range, coordination is needed in order to make the supply chain rebalance and realize the effective response on the emergency. The conclusions in the paper were verified by numerical simulations.
