Pricing Decision Models Of Closed-loop Supply Chain Under Different Conditions

The excessive waste and use of resources has led to serious lack of it,Now the development way of resource saving and environment friendly has become the inevitable choice of all countries.Therefore,in order to realize the reasonable allocation and use of the resources,the closed-loop supply chain has received the widespread attention.In real life,recycling of waste products and return makes the phenomena of the study of closed-loop supply chain model have more practical significance.According to the research background and research meaning of closed-loop supply chain,combined with a closed-loop supply chain research status at home and abroad.The main content of this paper is as follows.Fairness preference is introduced into a closed-loop supply chain.Then the sales effort and the recycling effort are introduced separately into the market demand function affected by the market price and the recovery function affected by the recycling price.Corresponding pricing decision models are established under two assumptions that only the manufacturer has fairness preference and only the retailer cares about the fairness.The influence of the preference coefficient on the decision-making strategy and system profit of supply chain is compared and analyzed.Analysis results show that the fairness preference behavior is an effective means to distribute the system profit of the closed-loop supply chain for the manufacturer and retailer.Meanwhile,the fairness preference in the closed-loop supply chain may lead to the loss of system profit and poor the social environmental condition,so facing fair preference reasonably becomes particularly important.Finally,we analysis some reached conclusions in this paper and give corresponding management by numerical simulation.Combining the return options and the return policy options,this paper construct a closed-loop supply chain model combining the traditional sales channel and the electronic channel.Under the condition of the return policy,having return options or not,we discuss the existence of the optional solution of the decision variables and get its optional solution.And then we analyze that the sensitivity coefficient of the return policy and the sensitive coefficient of return option affects the quantity of each decision.In the end,we verify the conclusion by a living example.
