Research On The Complexity Of Enterprise Dynamic Evolution Game In Supply Chain

With the increasing competition in the world and the development of science and technology, more and more enterprises begin to realize the importance of supply chain management. In this paper, several dynamic game models are given.The first chapter introduces the research background, significance and status of the complex dynamic phenomena in the supply chain.The second chapter mainly introduces some concepts and theories involved in the paper, including supply chain, game theory, system stability and chaos theory.In the third chapter, we consider a dual channel supply chain (CLSC),which is composed of one manufacturer and one retailer. We characterize the static and dynamic game models in a centralized and a decentralized dual channel supply chain. Then, we evaluates the influence of the degree of retail channel loyalty to pricing decision under the static model. Through numerical simulation, we analyzed the complex dynamic phenomena, such as the stability region, chaos, bifurcation diagram and the largest Lyapunov exponent diagram.Its find that, retail channel loyalty has a positive effect on the retail price and a inversus effect on the direct price; the retail price in decentralized supply chain is greater than centralized supply chain; the whole supply chain can get more profits under centralized decision.In the fourth chapter, we consider a multi-channel closed-loop supply chain consisting of two manufacturers and one retailer.We characterize the static and dynamic game models. The dynamic model is studied by using the stability region, bifurcation diagram and the maximum Lyapunov exponent. The results show that:the difference between direct selling price and retail price is small underthe manufacturer led, but it is big underretailer led; no matter the manufacturer led or retailer led, the direct channelcan make more profit of manufacturer thanrecycling channel; the manufacturer 1, manufacturer 2 and whole supply chain profits are improved under retailer led, retailer led can improve the overall supply chain efficiency.In the fifth chapter, the main content of this article is summarized and the direction of further research on this article is formulated.
