Research On The Inventory Control, Incentive Strategy And Structure Efficiency Of Supply Chain

With the new states of the competing structure of market and the market status of members in a supply chain changed, and with the keeping continuous development of economics, the strategies of inventory control, incentive mechanism and inventory control of reverse logistic as well as the loss of structure efficiency of remanufacture supply chain are studied in this thesis. The contents are as follows:An introduction to this thesis is given in Chapter 1. The literatures review on the relative research fields is summed up in Chapter 2. The competitive and cooperative ordering models are presented by using game theory and methods in Chapter 3. Using the game theory and the information economics, the validity for this incentive mechanism to improve the overall operational benefit in a supply chain is proved in Chapter 4. Assuming product returned and the recovery product as"renew", inventory control models based on different recovery modes are presented in Chapter 5. The efficiency of the serial supply chains with remanufacture is discussed in Chapter 6. And the conclusion and some prospects are given in Chapter 7.There are five innovations in the thesis:1. The shortage time or lead-time is regarded as a decision-making variable and supplier shared shortage cost of the retailer is supposed. By using quantitative analysis and numerical examples, the effects of the shortage time or lead-time on the relative costs are compared when the retailer and supplier hold the different positionsin in the supply chain.2. EOQ and NEWSBOY models are introduced to reverse supply chain study, and the new models that the returned products can be sold immediately, can be sold time-delayed, and can be batch recovered are presented. The affection of returned products to inventory control is studied as well.3. The constraint coefficientα(α≥1) is introduced in the incentive model of two-level supply chain. When price is constant and demand is stochastic, the order strategy model of retailer based on incentive mechanism of suppliers is established. It is proved in theory that incentive mechanism implemented by suppliers will increase the whole supply chain benefits and the retailer's promotion is relative to value-adding of products in the whole supply chain.4. A new model on innovation, cooperation and competition between manufacturer and retailer is presented according to the relationship of input and output. The interreaction of innovative actions investment in manufacturer and retailer as well as the affection of the proportionλshared by manufacturer to sales strategy are discussed.5. The efficiency of reverse supply chain is studied quantitatively. The efficiency loss of the serial supply chain with remanufacture based on different decision structures is discussed.
