Research On Optimal Retailer's Price And Inventory Decision Under Permitted Delay Of Payment

Delay payment is a popular way of short-term business loan, existing broadly in the business activity, particularly in the retail trade. Widely application of delay payment can make supplier to better understanding of the reputation condition of the retailer;Strengthen to the control of the retailer;reduce the cost of the supplier processing stock and cover up the price discrimination behavior more availably.Usually neglect the funds cost in the traditional retailer inventory decision research, there is a big gap between the optimal price and inventory decision of retailer and the realistic circumstances.Firstly, this dissertation put forward worthy of further research of four problems under this background,based on the review of a great lot related research papers:(1)When the delay payment is a temporary behavior, should the retailer need to adjust his nomal inventory decison?And how to make the optimal decision? (2)When the delay payment is conditional,how does the retailer make the optimal price and inventory decision? (3)When consider the retailer also give the delay payment to the customer, namely the two stages delay payment, how does the retailer make the optimal price and inventory decision? (4)How does the delay patment mechanism to carry out the stock coordination in the supply chain in the retailer dominated supply chain?Secondly, this dissertation set up the models or improve the existing models for the four realistic problem with mathematics method, using the inventory theory ,calculus, and probability theory etc. mathematics tool, solving these models, and finally give the optimal decision model of these problems.1) Set up the optimal price and inventory models under temporary delay payment. When the temproray delay payement existing one order cycle of retailer,this part give the choice principle and the optimal ordering model;when existing multi-order cycle,this part give the dynamic price and inventory decision model.2)Improving the existing model of coditional delay payment models,release the hypothesis under two kinds of conditions.One is the supplier give multi-cash discount point of delay payment,the other one is the retailer can partially delay payment.This part give the optimal inventory decision models under these two conditions and give the resolve algorithm. 3) Improving the existing model of two-stage delay payment models, release the hypothesis under two kinds of conditions. One is the supplier give full unit delay payment to the retailer,but the retailer give the partially delay payment to the customer.The other one is the delay payment which the retailer give to the customer can influence the customer demand.This part give the optimal inventory decision models under these two conditions and give the resolve algorithm.4) Considering the retailer dominated suppy chain, proved that delay payment can make the coordination of suppy chain when retailer participate to the decision of delay pay.Retailer can carry out the self interest but not to reduce the benefits of the supplier at the same time, This part also give the optimal inventory decision models under these situation and give the resolve algorithm.In a word, this dissertation replenished and improved the existing research of delay payment, set up four more effective decision models, have a certain theory and practice value. With related research continued, the hypothesises would be more close to the real world,the process of modeling and solving would be more complex,and the conclusion will be more applicable.
