Research on Dual Channel Dynamic Pricing of Community Fresh Food Supply Chain from the Perspective of Competition
In view of the characteristics of perishability,freshness and loss of fresh food,the influence of time,price and freshness are considered on the demand of traditional channels and community fresh food e-commerce channels,as well as factors such as preservation cost and inventory cost.The dynamic equilibrium models of fresh food community food suppliers and retailers are established by using differential variational inequalities.Key findings are as follows:First,fresh food has a dynamic pricing cut-off point in its sales life cycle.Suppliers and retailers can adopt different pricing methods according to the dynamic quality change characteristics,so as to realize the improvement of profits;secondly,in the dual-channel fresh food supply chain,enterprises can control the fresh-keeping costs and inventory costs of fresh products based on big data and the characteristics of residents'online shopping,and make pricing decisions,inventory planning and allocation for products in differ-ent regions,thereby reducing the need for fresh food products.Loss and waste due to expired food.Finally,the dynamic price discount strategy of suppliers and retailers'respective channels is analyzed through numerical example simulation,which provides a basis for suppliers and retailers to make decisions.
