Research on Eco-Industrial Chain Network Equilibrium Problem Based on Variational Inequality
摘要
Abstract
The eco-industrial chain network equilibrium model is researched by using the theories of variational inequality in this paper.The eco-industrial chain imitates natural ecosystem by manners of materials circulation and patterns of competition and symbiosis between biological colonies to make different enterprises share re -sources and exchange by -products.Then, it can make by-products generated in the production process of up -stream firms become the raw material for the production of downstream firms in order to achieve the maximization of economic and environmental benefits for the enterprises and the whole eco -industrial park.According to the network structure of multi-product(main product, by-product and waste)and multi-level in eco-industrial chain network, we describe the optimizing behavior of the various decision -makers, derive the equilibrium conditions of the system with the corresponding economic interpretation , and establish the eco-industrial chain network equilib-rium model.Based on the existence of the solution of the related variational inequality under reasonable assump -tions, a numerical example is given to illustrate the rationality as well as the effectiveness of the model .关键词
