Study On The Inventory Models Under Deterministic Demand

Inventory management is an important part of the supply chainmanagement, which is the key both to exert collaboration and to perform theintegrated management. With the development of economic globalization andtechnological progress, buyer's market has been formed, enterprise must realizelow cost operation based on the satisfaction of customers rapidly and effectively,and this is exactly the difficult problem that numerous enterprises face.Therefore, it is important to study the inventory for enterprises to reduce theinventory cost and improve the whole efficiency.This thesis does further research to the inventory problems underdeterministic demand, its main contents as follows:In Chapter 1, we firstly introduce the basic concept of supply chainmanagement. Then, we give the results of existed literatures and the purpose andsignificance of this thesis.In Chapter 2, the inventory-sate problem is considered, in whichreservation sale and reservations may cancel advance orders are included. Underthe assumptions that product demand is price-dependent and partialbackordering., the inventory and sale model is established by dynamic pricingapproach, in which time value of money is included. An approximate method isderived to find the optimal pricing, ordering quantity and maximize net profit.Numerical examples are presented. In Chapter 3, we study the inventory problem base on permissible delay inpayments. Base on price-depending demand and time-varying deterioration, thispaper studies the optimization of the buyer's profit by using strategy of delay inpayment. The model for optimizing the-cycle time and price is established andthe existence of its solution is analyzed. An approximate method is presented.Finally, several numerical examples are included.In Chapter 4, we study the production-sale inventory problem under limitedstorage capacity. The inventory model is established under the assumptions thatthe demand is linear and the-service level is restricted. The assemble cost,storage cost, shortage cost and postpone cost are considered, the optimal periodand production quantity can be determined and whether or not to lease thewarehouse can be choose according the actual situations. Numerical examplesare presented.Finally, the contents of the thesis are concluded and the further researchesare presented.
