Inventory Optimization Model Of Perishable Product Considering The Technology Investment With Trade Credit

Perishable goods are widespread in the daily life,as the change of time,if too much inventory,the phenomenon such as decay,damaged,depreciation will happen;If too little inventory,will cause procurement costs increase,the loss of sales opportunities.At present,the market consumption of perishable goods is increasing year by year,in the perishable product's life cycle is short,the seasonally strong,thus to strengthen its easy metamorphic product inventory management to regulate market supply and demand,as to provide theoretical basis for enterprise operation,enhances the enterprise the market competitive ability and so on has the very vital significance.As the speeding up of global economic integration,the competition between enterprises is increasingly fierce.In order to adapt to the high-speed development of economy,improve their own competitiveness,enterprises usually adopt various methods to increase sales,expand market share.Among them,the delay in payment is one of the most common strategy.Supplier can provide deferred to stimulate retailers to increase the order quantity,retailers can also use deferred alleviate the pressure of the fund itself,extra investment profits.Delay in payment as a way of short-term commercial credit,has been widely exists in commercial activities.In this paper,on the basis of existing research,for deferred the perishable goods model made a further study.Mainly includes two points:first,introduce the preservation technology model.Preservation technology would increase the cost of the retailer on the one hand,on the other hand,will decrease the rate of the perishable goods corruption,can produce both positive and negative influence of retailers' profits.This paper will introduce a preservation technology model,under the consideration of deferred payment in the secondary and tertiary,the retailer's optimal fresh-keeping technology investment strategy.Second,consider consisting of a supplier and a retailer and secondary optimal inventory under the commercial credit of the perishable goods and by a customer,consisting of a supplier and a retailer and level 3 under the commercial credit of the perishable goods the optimal inventory policy.According to the trade credit period and product ordering cycle,the relationship between points and circumstances,retailers optimal inventory model is constructed,Through theoretical derivation,solving the retailer's optimal order cycle,the optimal investment strategy;Finally,through the numerical analysis of the theorem is verified in the article,and the parameter sensitivity analysis.
