随机需求下基于公平关切的供应链合作效率分析

An Efficiency Analysis of Supply Chain Cooperation Based on Equity Concern under Stochastic Demand

基于供应链成员公平关切心理,以供应链合作效率作为研究对象,以成员公平中性为基础,分别探讨仅零售商具有公平关切、仅制造商具有公平关切、制造商和零售商都具有公平关切3种情况下的供应链合作效率问题。研究结果表明:零售商或双方具有公平关切时,合作效率会在某些区间内降低,供应链成员可以通过合理地设计公平关切系数,提高合作效率。仅制造商关注公平时,合作效率随公平关切系数而增大,制造商在合理范围内可以考虑设置公平关切系数提高合作效率。

Based on the concern of supply chain members about fairness, the efficiency of supply chain cooperation is taken as the research object and the fairness and neutrality of members as the basis. The efficiency of supply chain cooperation in three cases is discussed: only retailers have equity concern, only manufacturers have equity concern, and both manufacturers and retailers have equity concern. The maximum utility in three cases is found by Stackelberg game among two - level supply chain members, and then the cooperative efficiency of the three cases is calculated on the basis of fair and neutral utility. The research results show that when retailers or both parties have equity concerns, the cooperation efficiency will decrease in some interval, and the supply chain members can improve the cooperation efficiency through reasonable design of equity concern factors. When manufacturers only pay attention to fairness, cooperation efficiency increases with equity concern factor, and manufacturers can consider setting equity concern factor to improve cooperation efficiency within a reasonable range.
