Research On Pricing Game Model Of Closed-loop Supply Chain

Based on the game theory,this paper investigates the closed-loop supply chain models by using the knowledge of game theory and chaos.The paper buildings and analyzes the optimal pricing of the different sales channels and the different recovery channels.And the main contents of this dissertation are given as follows:First,this paper analyzes the background,significance and current status of the dynamic game models in the closed-loop supply chain.Second,it systematically introduces some of the concepts and theoretical basis,including closed-loop supply chain,game theory,system stability and chaos theory.Third,the paper puts forward a pricing game model for closed loop supply chain composed of one manufacturer and one retailer.The dynamic game model based on the retailer domination in recycling decision-making is investigated.The complex dynamic behaviors of the dynamic model are studied by numerical simulation means such as stability domain figure,bifurcation diagram and the largest Lyapunov exponent diagram.The results indicate that adjustment speed too fast can induce the system entering into chaos in the dynamic repeated game.Fourth,this paper investigates a dual-channel closed loop supply chain,which is composed of one manufacturer and one retailer.The effects of reference price on the decision making are also studied.The influences of the channel parameter and the reference parameter to pricing decision under the static model are analyzed,and then the complex dynamic phenomena are studied through numerical simulation.The results show that the collection rate is proportional to the reference price and inversely proportion to the channel coefficients in a static model.Among the effectiveness value range of channel parameter θ and the reference factor,the profits of the manufacturer decrease with the increasing of the value range of channel parameter and the reference price factor,while the retailers’ profits are vice versa.Fifth,the paper establishes and analyzes the models of single-channel recycling and dual-channel recycling,which are based on the closed loop supply chain(CLSC)of manufacturer and retailer.Under the decentralized decision-making,the Stackberg model and NASH model are investigated in the models of single-channel recycling and dual-channel recycling,respectively.And then the optimal pricing and profit in different power-dominated rules are obtained.Meanwhile,under the same dominant model,the optimal price and profit of manufacturer and retailer under the single-channel recycling and the dual-channel recycling are studied.It’s found that whether it is the manufacturer-managed,retailer-managed or Nash model,the profits of retailers under the dual-channel recycle are higher than that under the single-channel recycle.Dual-channel recycling model is more advantageous to benign development and stable operation of closed-loop supply chain.Finally,the main content of this paper is summarized and research directions and the outlook are put forward in the future.
