Study On Several Kinds Of Models With Product Pricing And Inventory

The price directly affects product demand on the market, and the demand is one of the important bases for enterprises to make production and inventory planning. By making reasonable price and inventory decision enterprises can reduce their inventory cost and achieve their anticipate goal. Therefore, the study on product pricing and inventory has great significance.In this thesis, some of product pricing and inventory models under deterministic demand conditions are studied. The main contents are as follows:In Chapter 1, we firstly introduce the basic knowledge of the product pricing and inventory management. Then, the recent research on the product pricing and inventory models is briefly reviewed, and the main results of this thesis are summarized.In Chapter 2, a production-sale inventory model is established for deteriorating items with advance sales and spot sales over the finite planning time, in which demand rate is price-dependent, production rate is controlled by demand and order cancellation rate is constant. Then, for a given number of replenishment, the existence of the corresponding optimal replenishment policy is proved and an algorithm to find the optimal replenishment policy is provided. Finally, numerical examples and sensitivity analysis are shown to illustrate themodel.In Chapter 3, an inventory problem with advanced sales is discussed, in which demand rate is a quadratic function of time and linear decreasing function of price, advance cancellation cost is an increasing function of time. Then, the character of the model is analyzed and an algorithm to find the optimal replenishment policy is provided. Finally, a numerical example and sensitivity analysis are shown to illustrate the model.In Chapter 4, under the assumptions that the demand rate depends on price and inventory level, production rate is limited, and shortages are allowed with partial backlogging, a production-sale inventory model is established over the infinite planning time. Then, for a given price, the existence of the corresponding optimal replenishment policy is proved and the algorithm is given. Finally, a numerical example and sensitivity analysis are given to illustrate the model.Finally, the research work of this thesis is summarized, and some suggestions about further researches are given.
