基于需求和生产成本偏差的Cournot竞争供应链协调

分析一个供应商和两个Cournot竞争零售商组成的供应链系统的协调问题.首先证明收益共享合约在稳定条件下能实现该供应链协调;当突发事件导致零售商面临的需求规模和供应商的生产成本同时与其预测值发生偏差时,为使供应链收益最大,提出了调整生产计划和零售价格的协调策略,进一步证明了改进的收益共享合约可协调需求和成本偏差的分权供应链;最后进行了数值实验.

SUPPLY CHAINS COORDINATION BASED ON DEMAND AND PRODUCTIOIN COSTS DISRUPTIONS WITH RETAILERS COURNOT COMPETITION

The coordination problem of a supply chain with one supplier and two Cournot competing retailers is analyzed. It is proved that a revenue sharing contract can be used to coordinate the supply chain under normal environment. When demand scale and costs were disrupted simultaneously in the planning horizon, a coordination mechanism about adjusting price and production quantity is proposed to maximize the profit of the supply chain. It is also proved that the improved revenue sharing contract can coordinate the supply chain when demands and costs are disrupted simultaneously. Finally, a numerical analysis is given.
