摘　　要：利用过度自信系数刻画零售商的过度自信行为,研究了由多个制造商和多个零售商构成的供应链网络均衡问题。借助变分不等式理论和互补理论,刻画了制造商和过度自信零售商的最优行为,构建了供应链网络均衡模型。解析分析了零售商的过度自信系数对其订购决策的影响。结果发现:随零售商过度自信系数增大,其产品均衡订购量增加且均衡订购价格升高;然后,借助数值算例验证了上述结论并讨论了过度自信系数对零售商的实际利润以及网络均衡模式的影响;最后,通过比较不同产品缺陷率情形下零售商的订购决策,分析了产品缺陷率对零售商订购决策以及网络均衡模式的影响。Overconfidence behavior of retailer is described by overconfidence coefficient, a supply chain network equilibrium problem which consisted of multiple manufacturers and multiple overconfident retailers was studied. Based on variational inequality theory and complementary theory, the optimal behaviors of manufacturers and overconfident retailers were modeled, and the supply chain network equilibrium pattern was established. The impact of overconfident behavior on the order decision of retailers was analyzed. The results show that： the retailers＇ equilibrium quantities and equilibrium prices increase with the overconfidence coefficient increasing. Then, numerical examples illustrate above conclusions and show the impact of overconfidence coefficients on retails＇ actual profit and network equilibrium. Finally, the effect of product defective rate on the retailer＇s ordering decision and network equilibrium model is analyzed by comparing the retailer＇s ordering decision with different product defective rate.
