非对称信息下市场需求与生产成本同时发生扰动时的供应链决策

Supply Chain Decision with Asymmetric Information When Demand and Production Cost Disrupt Simultaneously

对由一个生产商和一个销售商组成的两级供应链模型,基于以生产商为主导的Stackelberg博弈,针对需求函数分别为线性和非线性的情形,研究非对称信息下市场需求和生产成本同时扰动的供应链最优决策。在市场规模不确定的条件下建立生产商与销售商的利润函数,根据两类扰动之间的关系分四种情况确定供应链中各因素及总利润的最佳表示形式。通过数值仿真试验讨论供应链中各因素随扰动及市场信息变化而变化的各种趋势和最优生产量在一定条件下的鲁棒性,并进一步说明非对称信息下两类扰动对供应链的影响。

Based on the supplier--leader Stackelberg game, optimal policies for a one--supplier --one--re- tailer supply chain with asymmetric information when demand and production cost disrupt simultaneously are studied with the assumption of line and nonline demand functions. First, the profit functions of suppli- er and retailer are given under asymmetric information. Then, the expressions are developed for optimal supply price, optimal retail price, optimal supplier profit, optimal retailer profit and total profit of supply chain. Finally, the some variation tendencies of the supply chain members with two disruptions via numer- ical simulation are discussed, and the robust of optimal production under some conditions is obtained. The results show that two disruptions have a strong influence on supply chain with asymmetric information.
