竞争回收平台双向公平关切下逆向供应链的决策分析

Decision Analysis of Reverse Supply Chain under Bidirectional Fairness Concerns of Competitive Recycling Platforms

基于单一再制造商和两个竞争回收平台构成的逆向供应链系统,引入回收平台的双向公平关切行为,建立公平中性情形、再制造商关注和不关注回收平台双向公平关切行为情形的3种定价决策模型,利用Stackelberg博弈理论分析各成员的均衡策略。研究表明:两回收平台的过度竞争行为对逆向供应链的运作不利;消费者对回收价格敏感程度的增加有利于系统成员利润及效用的提高;两回收平台的纵向公平关切行为能够增加其讨价还价能力,横向公平关切则反之;再制造商做决策时应该关注两回收平台的双向公平关切行为,这对提高废旧产品回收量、系统成员利润及效用均有利。

In this paper,a reverse supply chain system which consists of a single remanufacturer and two competitive recycling platforms is constructed,introducing bidirectional fairness concerns of the recycling platforms,and three different recycling price models are constructed under three different situations in which the members are neutral and the remanufacturer respectively considers as well as ignores recycling platforms’behavior of bidirectional fairness concerns.The equilibrium strategy of the members is analyzed by Stackelberg game theory.The results show that excessive competition between the two recycling platforms is unfavorable to the operation of the reverse supply chain;increasing the consumer sensitivity of collection price is favorable to improving the profit and utility of the members;vertical fairness concerns of the two recycling platforms can increase their bargaining power,while horizontal fairness concerns are the opposite;the remanufacturer should consider recycling platforms’behavior of bidirectional fairness concerns when making decisions,which is favorable to increasing the amount of recycling waste products,the profits and utilities of the members.
