电子商务下全球闭环供应链超网络模型

A Model of Global Closed-loop Supply Chain Supernetwork Under Electronic Commerce

建立了一个由制造商、零售商、消费者与回收商构成的全球闭环供应链超网络均衡模型。回收商回收、处置废弃产品,并将生产出的新产品销售给零售商与消费者。模型中的交易方式包括传统交易与网上交易。考虑有多种交易货币,模型设定了不同货币对基础货币的增值率。首先对各层决策者的行为进行了研究,探讨了它们之间的相互作用,又运用变分不等式的相关知识,建立了一个有限维的变分不等式模型,得到了全球闭环供应链超网络达到均衡的条件。最后,算例分析证明了模型的有效性。

A global closed-loop supply chain supernetwork equilibrium model is developed, which is constructed by manufactures, retailers, consumers and recyclers. The recyclers reclaim and dismantle the discarded products, and sell the new commodity to the retailers and consumers. Different decision-makers transact in two ways, the traditional transactions and the electronic commerce transactions. The model sets the value-added rates for the different currencies because of the multy trading currencies. The behavior of the de- cision-makers and their independent behaviors are studied, and a finite-dimensional variational inequality formulation is established. The equilibrium conditions of global closed-loop supply chain supernetwork are derived. A numerical analysis on a test case illustrates the effectiveness of the model.
