【摘要】 研究了制造/再制造工厂通过分销/回收中心实体链和通过电子商务直销渠道,将其产品经由零售商/回收点销售给具有模糊需求的消费市场的双渠道闭环供应链网络均衡问题。利用模糊事件的可信性测度理论,推导了零售商/回收点的模糊销售量、存储量和缺货量的可信性分布以及其期望,建立了零售商的期望利润模型。通过变分不等式理论,刻画了不同决策者的最优行为,建立了具有模糊需求的双渠道闭环供应链网络均衡模型。设计了求解均衡解的修正投影算法,结合算例讨论了模糊需求对均衡解的影响。研究表明,制造/再制造工厂加入直销渠道会增加制造/再制造工厂、零售商/回收点及供应链的总期望利润,但会减小分销/回收中心的利润。更多还原

【Abstract】 A dual channel equilibrium model of a competitive closed-loop supply chain network is developed in this paper,in which both physical and electronic transactions.The retailers/recovery points are faced with fuzzy market demand.Based on the credibility measure of fuzzy event,the credibility distribution and the expected value of fuzzy sale and fuzzy inventory and fuzzy shortage at the retailer are derived,therefore the retailer’ s expected profit is constructed. With the help of variational inequality theory,the network structure of the closed-loop supply chain is identified and the dual channel equilibrium conditions are derived.The modified projection algorithm is designed for solving the equilibrium pattern.Finally,numerical examples are given to illustrate the impact of fuzzy mark demand on the equilibrium results.The profit of manufacture/remanufacturing firms,retailers/recovery points and supply chain are increased by adding a direct channel.However,the profit of distribution/recycling centers is decreased.更多还原
