Research On Inventory Control Strategy Of Fresh Products With Backorder Under The Multi Period

Along with the development of economic, people’s living standards are improved, They have more and more demand for fresh products that are rich in nutrients, at the same time they put forward more requirements on the price, quality, and distribution of fresh timely fast, high product freshness etc. Due to the features such as perishable, short freshness, fresh product logistics need special measures to administrate such as fast delivery, low temperature storage, which makes the fresh product logistics and inventory cost become greatly increased. it has a serious influence on fresh product sales profit. This article adopted in the inventory cycle, shortage of time decision variables such as selection, promotion price to explore fresh inventory optimization. This article main research content is as follows:First of all, based on the constant deterioration rate under two kinds of inventory control model, study of demand is constant and demand under uncertainty respectively, considering the case that the cost of capital used research models and shortage of deeplying supply rate is under a situation that the waiting time is decreasing, the optimal inventory strategy in a period of metamorphic.The purpose is to determine the optimal order times and design the best out of stock time, in order to get the maximum profit.Secondly, study the linear deterioration rate normally sold inventory control strategy, researching under the condition of linear deterioration rate, considering the cases that the cost of capital using and allowed out of stock and out of stock after decreasing supply rate for waiting time situations, in a period of metamorphic, the purpose of optimal inventory strategy is to determine the linear deterioration rate of optimal order times and get the best out of stock in time,in order to get the maximum profits, and sensitivity analysis of relevant factors.Finally, under the influence of price and fresh metamorphism in shortage, research on the basis of rate change with time after the best pricing strategy and the optimal order times. on the basis of previous model, demand is the function about the price and time, to establish model, to carry on the model, it is concluded that optimal order times and the best pricing strategy.This paper constructs the multiple models under the condition of multi cycle fresh product inventory model, and was used to solve the model that under each order times the shortage of time, for choosing the optimal order times and the shortage of time point selection, provides the theory basis of accurately, and the deterioration rate, the strength of customer repurchase, inventory holding cost, unit cost, unit cost sensitivity analysis, and the size of each factor’s influence on profit is analyzed, scheme provides a theoretical basis for the optimal inventory optimization and the optimization direction. Study at the same time when the price and fresh freshness affect demand for product pricing strategies under the condition of fresh profits, and provide the theoretical basis for the optimal pricing strategy.
