Study On Update Strategy Of Closed Loop Supply Chain For Short Life Cycle Electronic Product

The acceleration of the short life cycle electronic product update not only leads to the instability of the market demand,but also makes it difficult for the enterprise to formulate the product update strategy.At present,the research on closed loop supply chain for short life cycle electronic products is just beginning,and its market demand prediction,update strategy and recovery strategy are relatively few.So the research is carried out in the paper.Market demand forecast for the short life cycle electronic product update stage.In this paper,we analyze product similarity feature weight and product similarity by fuzzy rough set and system similarity measure,and solve the problem of lack of prediction data by similarity and sales data of similar products.On the basis of the traditional BASS demand forecasting model,the consumer utility value is introduced to improve the accuracy of the demand forecast.Finally,the paper get the BASS market demand forecasting model for short life cycle electronic products by the product similarity and consumer utility.The analysis of the short life cycle electronic product update strategy and recovery strategy.In this paper,the best strategy of the supplier in the product update stage is discussed under the method of game theory,which are manufacturer led,retailer led,Nash equilibrium and centralized decision-making.Meanwhile,the optimal recovery strategy of manufacturers and retailers under different channel capacity is analyzed.Through the short life cycle electronic product renewal prediction model,this paper analyzes the market demand of E and F two laptops products update stage.Based on the results of demand forecasting,the optimal renewal policies of these two laptops under different channel capacity structure and the optimal recovery strategy under different recycling channels are analyzed.Based on the earnings of the manufacturers and retailers under different channel capacity structures,the profit interval between manufacturer and retailer under centralized decision is given.
