需求不确定下供应链间古诺博弈决策分析

Decision Analysis of the Cournot Game between Supply Chains under Uncertain Demand

通过引入区间数和心态指标将需求函数模糊化,研究了需求不确定下供应链间竞争的决策问题。首先,分别构建了分散-分散决策、集中-分散决策和集中-集中决策三种模式下的供应链间价格竞争模型;其次,分析了不同竞争模式下市场规模等变量对零售价格、顾客需求量和供应链利润的影响;最后,以两条供应链为例,进行算例分析,并在此基础上,进一步分析了心态指标、市场规模等变量对最终决策结果的影响。

According to the introduction of interval fuzzy numbers and attitude index to demand function,a decision problem about price competition between supply chains under uncertain demand is studied.Firstly,the decision model of price competition about decentralized-decentralized,centralized-decentralized,and centralizedcentralized models is constructed.Secondly,the impact of some related variables on retail price,customer demand and supply chain profit under the three competition models is analyzed.Finally,a numerical example for two supply chains is given and the influence of the attitude index,market size and other variables on the final decision results is analyzed.
