Perishable Goods Inventory Strategy Based On Time Varying Demand

Perishable goods are widespread in the daily life. With the change of time, if thestock is too much, the phenomenon such as decay, damage and devaluation will happen.If the stock is too little, it will lead to an increase in purchase costs and a loss of salesopportunities. At present, China’s market in a variety of perishable goods consumptionis increasing year by year. The life cycle of perishable goods is short and the seasonal isstrong. Therefore, strengthen the inventory management of perishable goods has a veryimportant significance to adjust the market supply and demand,provide a theoreticalbasis for the operation of enterprise and improve the enterprise competition ability inthe market.This paper first discussed the research background and significance, detailedanalyze the domestic and foreign scholars on the current situation of the perishablegoods inventory strategy.

Constructed the perishable goods inventory cost model based on thetwo modes of continuous and discrete demand. Finally, the inventory cost minimizationas the goal, to optimize the retailer’s out of stock point, and carried on the exampleanalysis and parameter sensitivity analysis.
