随着循环经济的兴起,废弃物的回收、再利用逐渐得到重视,闭环供应链也由此成为研究重点.以变分不等式理论为基础,构造一个由制造商、零售商、消费者与回收公司构成的闭环供应链网络均衡模型.鉴于电子商务的迅速发展,模型考虑了网上交易形式,讨论了网络中各层决策者的独立行为及其相互作用,进而获得该系统达到均衡状态的条件.数值算例验证了该模型的有效性.
With the rise of circular economy, the recovery and reuse of waste have gradually been taken into consideration, and the closed-loop supply chain has become the focus of the study.On the basis of the variational inequality theory, a structure composed of manufacturers, retailers, consumers and recycling companies In view of the rapid development of e-commerce, the model considers the form of online transactions, and discusses the independent behavior and interaction of decision-makers at all levels in the network, and then obtains the condition that the system reaches an equilibrium state. The example shows the validity of the model.
