| Popis: | 95 Under the tendency of globalization, the businesses of supply chain cooperate to promote competitiveness. The most important things for management in supply chain are integrating manufacturers and retailers, reducing costs and increasing revenues efficiently. Due to the imperfection of supplier’s production processes, artificial negligence and the fault of carried process, the retailer receives items which included defective items. If the retailer sells the defective items to consumers, it would cause the consumers to complain and to request to return or indemnify, which is all-important to enterprise’s business. In addition, in order to decrease the inventory cost, the retailer will order fewer items. It will result in shortage and the partial consumers will probably buy what they need from other retailers. Therefore, it is important to decide the inventory quantity for enterprise’s business. Furthermore, the manufacturer often offers the retailer a trade credit to improve sales and reduce stocks. If the retailer orders with more quantity, the manufacturer will offer longer due date of delay payment. This thesis extends the integrated inventory models of Ho (2005) and establishes integrated retailer and manufacturer inventory models under permissible delay in payments. Chapter 1 involves the motivation and objective of this thesis. In this chapter, literature review about relative research papers is also included. Chapter 2 considers the defective items in retailer’s arrival order lot with partial backlogging. We establish an integrated retailer and manufacturer inventory model under permissible delay in payments. In Chapter 3, we extend model for Chapter 2, in which shortage is allowable and defective rate is considered as a random variable. We set up an integrated retailers and manufacturers inventory model under the effect of an order-size dependent trade credit. The necessary and sufficient conditions of the existence and uniqueness of the optimal solutions for the two models are shown. Numerical examples are provided to show the solution procedure and the sensitivity analyses of the optimal solution with respect to parameters of the systems are also carried out for understanding how parameter changes influence the optimal solution. Finally, Chapter 4 provides the conclusion of this thesis and future research directions are proposed. |
