文章研究了制造商/回收中心将新旧产品分开来销售,满足不同消费者需求,其中新产品经一级零售商售予一级需求市场,旧产品经二级零售商售予需求随机的二级需求市场的网络均衡问题.将闭环供应链网络均衡模型的求解问题转换为等价的变分不等式求解问题,并利用Nash均衡理论得到了整个闭环供应链达到均衡时的均衡条件,设计了求解该模型的投影收缩算法.结合算例对模型的合理性进行了验证,结果表明:适当提高废旧品的转化率、可再制造品占有率、可修复品占有率对网络整体及资源的循环利用都具有促进意义.
The article studies the manufacturer / recycling center to sell old and new products separately to meet the needs of different consumers. Among them, the new products are sold to the first-level demand market through the first-level retailers and the second-level retailers sell the old products to the second- The problem of network equilibrium in the demand market is solved.The problem of solving the equilibrium network model of closed-loop supply chain is transformed into the equivalent problem of variational inequality, and the equilibrium condition of the closed-loop supply chain is obtained by using Nash equilibrium theory. Projection Shrinkage Algorithm for the Model. The rationality of the model is verified with the examples. The results show that: the conversion rate of waste products, the share of remanufactured products, the share of repairable products, Has a positive meaning.
