Research Of Manufacturer's Decision In Replacement-subsidy Under The Regulations Of The Government

The idea of protecting ecological civilization and green sustainable development has been deeply rooted in the hearts of the people.Secondly,in our country is vigorously implementing extended producer responsibility system,the system emphasizes the manufacturing enterprises not only need to be responsible for the production of their products,but also require manufacturers responsible for processing of products scrap,so the closed-loop supply chain has been a hot research.This paper focuses on the study of how to improve the waste products in the closed loop supply chain.This paper designs a closed loop supply chain composed of manufacturers,recyclers,governments and consumers.Manufacturers not only produce new products,but also entrust third party recyclers to recycle waste products and use this to produce products.Manufacturers not only produce products,but also sell products.This paper subdivides products according to the characteristics of new products and remanufactured products,and establishes supply demand models respectively.In order to improve the recovery rate of waste products,the government's reward and punishment mechanism,subsidy mechanism,reward and punishment mechanism and subsidy mechanism are studied under the dual function of closed loop supply chain decision making.The effects of different mechanisms are compared and analyzed.First of all,this paper establishes the basic model of old and new closed loop supply chain,and subdivides new products and remanufactured products,and gets the following conclusions based on the analysis of model decision.Secondly,in order to improve the recycling of waste products and recycling rate,this paper studied the incentive mechanism,government subsidy mechanism,the incentive mechanism of supply chain model of closed-loop supply chain model,subsidy mechanism of supply chain model and incentive mechanism and subsidy mechanism of dual action are established.Through the model of decision analysis and comparison this paper draws the following conclusions: 1.The incentive mechanism for the recovery of waste products is very small effect,and indirect effect on incentive mechanism of waste products recycling,the incentive mechanism can't be applied to the retail price of the product,but the incentive mechanism can improve the recovery of waste products by affecting the manufacturer's profit;2.The subsidy mechanism plays a great role in the closed-loop supply chain.The subsidy mechanism affects the demand of products and the recovery and recovery rate of waste products by directly affecting the retail price of products.3.The effect of government double regulation on supply chain is independent,and it is the superposition of the effect of the two kinds of regulation methods.4.When the new product replaces the remanufactured product,and the remanufactured product cannot replace the new product,the price of the product under the dual regulation is equal to the price under the subsidy mechanism;When the manufacturer's subsidy rate to the consumer of remanufactured product is less than 0.5,the price is less than the mechanism of reward and punishment and the mechanism of no reward and punishment.When the manufacturer's subsidy rate to the consumer of remanufactured product is more than 0.5,the relationship of prices is opposite.Under the dual regulation,the demand for new products is equal to the demand of the product under the subsidy mechanism.When the manufacturer's subsidy to the consumer of remanufactured product is less than 0.5,it is larger than the demand of new product with reward and punishment mechanism and without regulation.When the manufacturer's subsidies for the consumer of remanufactured product are more than 0.5,the relationship of the demand of new product is opposite.Anyway,the demand of the remanufactured product is always larger than the demand of remanufactured product with reward and punishment mechanism and without regulation.When new products can replace remanufactured products,remanufacturing products can replace new products,and the replacement degree is the same,the price of new products under the double regulation is equal to the price under the subsidy mechanism,and larger than the price of new product under the mechanism of rewards and punishment and non-regulation.The relationship between the price of remanufactured products under the double regulation and under the reward-punishment mechanism or under non-regulation depends on the manufacturer's subsidy to consumers.The demand of new products under the double regulation is equal to the demand of the product under the mechanism of the subsidy and punishment,less than the demand of the products under the mechanism of reward and punishment and the non-regulated product.The demand of the remanufactured product is equal to the demand of the product under the subsidy mechanism,which is greater than the mechanism of reward and punishment and the production of reproduction under the regulation.The demand and recovery rate are the same.Finally,the model decision and analysis are verified by numerical simulation.
