So the inventory management of fresh products is more important. Meanwhile some scholars launched studies on the inventory and sales of fresh products. The preliminary research results are as follows： Wee[1] construct an inventory model under some conditions that product’s life is subjected to double parameter weibull distribution. Wee and yu[2] found out how quantity discount affected the inventory strategies of retailers. Monahan[3] studied quantity discount problem from the perspective of suppliers. Tersine[4] studied the temporary price discount and presented OTOS（one time only sale）， then Tersine[5] also proposed a generalized EOQ model which was given temporary price discounts； 　　Currently in the study of inventory model on price discount decision， the demand rate is mostly assumed to be price-related functions without considering the effects of freshness on demand.
