Game Research On Closed-loop Supply Chain Pricing Of Construction Waste Recycling And Remanufacturing

The construction industry is one of the pillar industries in China.With the promotion of ecological civilization construction and green development,the reuse of construction waste has become an important research topic."More manufactured goods(Remanufactured products)" and "new product" coexistence and the Reverse supply chain(Reverse supply chain)is the main characteristic of marketization of construction waste recycling and mechanism.Improving the pricing mechanism of the participating entities is a prerequisite for.ensuring the stability of the closed-loop supply chain system,and can guarantee the profits of the participants in the closed-loop supply chain.It is of great significance for improving the efficiency of recycling of construction waste,reducing environmental pollution,and building a harmonious symbiosis between man and nature.On the basis of summarizing the research results in related fields at home and abroad,this paper uses supply chain theory,chaos and complexity theory to study the pricing and system stability of decision participants under the framework of game theory,and puts forward relevant suggestions and opinions to the participants according to the research conclusions.The main contents include:(1)By comparing the traditional construction waste management model and the advantages and disadvantages of the forward supply chain and the reverse supply chain and analyzing the benefits of the closed-loop supply chain,the paper points out the necessity of the closed-loop supply chain in the construction industry.Under the meta-scenario,the closed-loop supply chain system of construction waste recycling and remanufacturing discusses the complexity of the pricing and system stability of decision-making participants.(2)Constructed a system dynamic pricing game model under the "government-market"binary scenario,in which the prices of "new products" and "remanufactured products"in the market are different.The participants in system decision-making are all multi-period discrete games with their respective maximum profits as the goal,and the equilibrium strategy of the two situations is solved.(3)Through the case and numerical simulation,the problems of pricing and system stability in the multi-period decision-making of system decision-making participants under the "government-market" binary scenario are analyzed,and the impact of construction waste recovery rate on system profit.At the same time,the chaotic attractor and the initial value sensitivity in the chaotic state are also analyzed,and the delayed feedback control method is used to effectively control the chaotic state.
