Research On Multi-period Closed-loop Supply Chain Network Equilibrium Models Considering Participants' Behaviors

At present,with the rapid increase in population,the rapid development of the social economy,and the rapid increase in the demand for human being products,it is accompanied by increased environmental pollution and problems.To alleviate the contradiction between demand and environmental pollu tion,all countries in the world have issued relevant laws and policies from the perspective of sustainable development to promote the sustainable development of the environment.The closed-loop supply chain is the perfect combination for the forwarding and reversing supply chain,which forms a closed-loop structure of resources.Therefore,the closed-loop supply chain could improve the sustainable development of resources.In practice,there are often member enterprises at the same level,and multiple upper-lower member enterprises,and multiple demand market in the supply chain,which form a complex structure of closed-loop supply chain network.Moreover,the behavior of enterprises is often multi-period and long-lasting,so it is a great meaning to research the multi-period closed-loop supply chain network equilibrium.Besides,a large number of behavior management sciences and behavioral economics have proved that the behavior of participants has a significant impact on the supply chain.Therefore,the re search considers the influence of the factor of participants' behaviors on the multi-period closed-loop supply chain network equilibrium,which not only helps to enrich and expand the theoretical research of the multi-period closed-loop supply chain network but also help improves sustainable development of multi-period closed-loop supply chain network,which could provide strategic guidance and management reference for decision-makers at all levels in the multi-period closed-loop supply chain network.By summarizing the current research situation,based on the existing research and combined with the actual market background,this dissertation aims to analyze the multi-period closed-loop supply chain network equilibrium from the perspective of participants' behaviors,which considers enterprises' sales effort behavior,enterprises' CSR behavior and consumers' preference for products(new product,remanufactured product).This paper studies the multi-period closed-loop supply chain network equilibrium under the conditions of enterprises' marketing efforts behavior,enterprises' CSR behavior,and consumers' preference for products.Meanwhile,using Nash non-cooperative games,Duality theory,Trade-off Theory,Space Price Equilibrium Model,and Variational Inequality,this paper constructs a multi-period closed-loop supply chain network equilibrium model considering the behavior of participants,and adopts the modified projection algorithm to solve the equilibrium model.Firstly,this paper considers the influence of enterprises' marketing efforts behavior on the multi-period closed-loop supply chain network equilibrium.Starting from the hypothesis of “rational broker”,in this dissertation the multi-period closed-loop supply chain network equilibrium model is built.Through numerical examples,the effects of manufacturers' marketing efforts behavior,retailers' marketing efforts behavior,and both manufacturers' and retailers' marketing efforts behavior on the multi-period closed-loop supply chain network are studied.Through the comparison and analysis of the results of the above three kinds of enterprises' marketing efforts behavior,the dissertation summarizes the influence of enterprises' marketing efforts behavior on the multi-period closed-loop supply chain network equilibrium.Secondly,the influence of enterprises' CSR behavior on multi-period closed-loop supply chain network equilibrium is considered.Starting from the assumption of “no-rational broker”,that is,the enterprises not only pursue pure-profit but also considers the interests of stakeholders and social welfare,the dissertation constructs the multi-period closed-loop supply chain network equilibrium model under the enterprises' CSR behavior.Through numerical examples,the effects of manufacturers' CSR behavior,retailers' CSR behavior,and manufacturers' and retailers' CSR behavior on the multi-period closed-loop supply chain network equilibrium are studied.Through the comparison and analysis of the results of the above three kinds of enterprises' CSR behavior,this dissertation summarizes the influence of enterprises' CSR behavior on the multi-period closed-loop supply chain network equilibrium.Thirdly,considering the influence of consumers' preference for products behavior on the multi-period closed-loop supply chain network equilibrium,this dissertation constructs the multi-period closed-loop supply chain network equilibrium model under the consumers' preference for products behavior.Through numerical examples,this paper study the influence of consumers' preference for products on multi-period closed-loop supply chain network equilibrium in multi-period fixed and no-fixed cases.Through the comparison and analysis of the results of the above two kinds of consumers' preference for products behavior on multi-period closed-loop supply chain network equilibrium,the influence of consumers' preference for products behavior on the multi-period closed-loop supply chain network equilibrium is explored.Finally,a multi-period closed-loop supply chain network in the mobile phone industry is selected as an example to study the multi-period closed-loop supply chain network equilibrium under the participants' behaviors.Through data collection and sorting,the empirical multi-period closed-loop supply chain network correlation function is fitted.Based on the existing models and algorithms,this dissertation analyzes the influence of enterprises' marketing efforts behavior,enterprises' CSR behavior,and consumers' preference for products behavior on the empirical multi-period closed-loop supply chain network equilibrium.It verifies the effectiveness of this model.At the same time,it also provides relevant management inspiration and decision-making suggestions.This dissertation also provides scientific management basis and decision-making reference for the managers of the node enterprises on this multi-period closed-loop supply chain network.
