Research on Closed-loop Supply Chain Network Equilibrium Model

Abstract

In order to study the problem which includes the manufacturer, two-stage distributors and the consumer market, a four-tier closed-loop supply chain network equilibrium model is developed, and the closed-loop supply chain network equilibrium are analyzed and the variational inequality models are established. And the modification projection method is to solve the model combining with specific examples. The result verified the validity of the model and method.
