Unlike the traditional integrated supplier–buyer coordination model, this research incorporates overlapped delivery and imperfect items into the production–distribution model. This model improves the observable fact that the system might experience shortage during the screening duration and also takes quantity discount into account. This approach has not been discussed in previous integrated su...

This study proposes a two-phase, algebraic approach to resolve the rotation cycle time and number of shipments for a multi-item, economic production quantity (EPQ) model with a random defective rate. A conventional method for solving a multi-item EPQ model is to use differential calculus and Hessian matrix equations on system cost function to prove convexity first and then derive an optimal pro...

This chapter focuses on the success and failure of international technology transfers. It shows that technology transfers are not correctly addressed by referring only to the contracting of a technology. This is a crucial question to any vendor of technology and any buyer of technology. In fact, by limiting the chapter to what seems a specific question, we will present an account of a larger de...

The allocation of cost savings is very important for the success of the joint relationship between the buyer and vendor in supply chain management. This paper develops integrated models with permissible delay in payments for determining the optimal replenishment time interval and replenishment frequency. In addition, the variant pricing strategy is employed to obtain both sides’ cost savings in...

In this paper, we consider the single vendor single buyer integrated production inventory problem. We relax the assumption of deterministic demand and assume that the lead time is varying lineraly with the lot size. The lead time is composed of a lot size-dependent run time and constant delay times such as moving, waiting and setup times. A solution procedure is suggested for solving the propos...

In this research, a coordination mechanism based on a credit period in a two echelon supply chain with one buyer and one supplier, is designed. The buyer is faced with uncertain demand by coping with normal distribution. Both lead time and ordering cost for receiving his order can be reduced at an added cost; in other words, they are controllable. The optimization models with and without integr...

This is a conceptual article dealing with the role of motivated reasoning in vendor selection. The authors argue that organizational buyers’ motivated reasoning, along with the task characteristics of perceived importance and familiarity, plays an important role in determining whether an open or a closed consideration will be used for vendor selection. Based on the relationship between motivate...

This article reviews literature on competitiveness of agricultural product and input markets. Although researchers in the United States and Europe emphasize different stages of the agricultural and food marketing system, their focus is similar: extent of buyer power, although both have largely ignored the sector supplying inputs to agriculture. The key conclusion is that there is little robust ...

In this paper we study the coordination of the two-echelon supply chain using credit and quantity discount options. We determine the retail price, order quantity for the buyer, and the setup frequency, credit period for the supplier in four different scenarios (with or without coordination and with or without credit option). And we suggest a policy that incorporates both quantity discount and c...

In this study, we investigate an integrated production-inventory system consisting of a single-vendor and single-buyer. The buyer manages its inventory level periodically at a certain period of time. We consider a fuzzy annual demand, imperfect production, inspection errors, partial backordering, and adjustable production rate in the proposed model. Additionally, it is assumed that the protecti...
