Abstract: Based on the traditional reverse logistics network framework, a closed-loop supply chain supernetwork model of automobile industry was established which consisted of raw material suppliers, part suppliers, manufacturers, distributors, retailers and recyclers. And variation inequality formulation was used to describe independent behaviors of different decision-makers and interactive competitive behaviors among decision-makers so as to derive the equilibrium for each competitive member of supply chain and for the entire supply chain. Trade price and volume for different decision-makers in system were determined, effective logistic flow among supply chain members was promoted and uncertainty for the entire closed-loop supply chain was reduced. The scientific analysis was provided by proposed method to improve the benefit equilibrium and long-term stable development of entire closed-loop supply chain.

Key words: automobile industry, closed-loop supply chains, supernetwork, variation inequality formulation, equilibrium
