In supply chain management process, the firm select best supplier takes the competitive advantage to other companies. Thus, supplier selection is an important issue and with the multiple criteria decisionmaking approach, the supplier selection problem includes both tangible and intangible factors. This paper is aimed to present an integrated fuzzy and linear programming approach to the problem....

W study capacity reservation contracts between a high-tech manufacturer (supplier) and her oem customer (buyer). The supplier and the buyer are partners who enter a “design-win” agreement to develop the product, and who share the stochastic demand information. To encourage the supplier for more aggressive capacity expansion, the buyer reserves capacity upfront by paying a deductible fee. As cap...

In this paper, we highlight a number of problems arising with a commonly used supplier selection method: the weighted factor score method. We discuss the behavior of this method with respect to weighting, scaling issues, and relative scoring. Assuming that there is no convex dominance, we formally prove that with the same supplier selection method, we can make any supplier win by judiciously ch...

The University of Guelph requires all suppliers and subcontractors to adhere to the University of Guelph's Code of Ethical Conduct for Suppliers and Subcontractors [1]. In indicating their own compliance with the code, suppliers accept responsibility for ensuring that all immediate subcontractors in all their supply chains are also in compliance. The University of Guelph will engage in construc...

Supplier selection is the process by which firms identify, evaluate, and contract with suppliers. The supplier selection process deploys a tremendous amount of a firm’s financial resources. In return, firms expect significant benefits from contracting with suppliers offering high value. This article describes the typical steps of supplier selection processes: identifying suppliers, soliciting i...

This paper is focused on the coordination of order and production policy between buyers and suppliers in supply chains. When a buyer and a supplier of an item work independently, the buyer will place orders based on his economic order quantity (EOQ). However, the buyer’s EOQ may not lead to an optimal policy for the supplier. It can be shown that a cooperative batching policy can reduce total c...

We consider the order fulfillment process of a supplier producing a customized capital good, such as production equipment, commercial aircraft, medical devices, or defense systems. As common in these industries, prior to receiving a firm purchase order from the customer, the supplier receives a series of shared forecasts, which are called ‘soft orders’. Facing a stochastic internal manufacturin...

Supplier selection process has gained importance recently, since the cost of rawmaterials and component parts constitutes the main cost of a product and most of the firms have to spend considerable amount of their revenues on purchasing. Supplier selection is one of the most important decision making problems including both qualitative and quantitative factors to identify suppliers with the hig...

We study a single-product setting in which a firm can source from two suppliers, one that is unreliable and another that is reliable but more expensive. Suppliers are capacity-constrained, but the reliable supplier may possess volume flexibility. We prove that in the special case in which the reliable supplier has no flexibility and the unreliable supplier has infinite capacity, a risk-neutral ...
