In most of the literature dealing with vendor-buyer inventory problems are focuses on the joint inventory models. However, in many practical situations, the relationship between vendor and buyer might be the leader and the follower. In Game Theory, this relationship is called as non-cooperative situation. We attempt to investigate relationships between the vendor and the buyer utilizing two different approaches which are Stackelberg’s leader-follower game model and interactive cooperative game model. Three inventory models are presented to determine the optimal size of each shipment from the vendor to the buyer, the total number of shipments per lot from the vendor to the buyer, and the optimal product price. In this study, the vendor production process is assumed to deteriorate during processing and produce a certain number of defective items. Then, the mathematical models are derived and the solution procedures are established to find out the best solution. Finally, numerical examples are given to illustrate the developed models. Sensitivity analyses are also performed and discussed.
