There are many benefits for coordination of multiple suppliers when single supplier cannot satisfy buyer demands.  In addition, buyer needs to purchase multiple items in a real supply chain. So, a model that satisfies these requests has many advantages. We extend the existing approaches in the literature that assume all suppliers need to be put on a common replenishment cycle and each supplier ...

In today’s highly rival market, an effective supplier selection process is vital to the success of any manufacturing system. Selecting the appropriate supplier is always a difficult task because suppliers posses varied strengths and weaknesses that necessitate careful evaluations prior to suppliers’ ranking. This is a complex process with many subjective and objective factors to consider ...

Supplier selection is one of the most crucial activities performed by the organizations because of its strategic importance. A supplier selection problem is a multiobjective problem involving both quantitative and qualitative criteria. Over the years a number of quantitative approaches have been applied to supplier selection problems. Although the Analytic Hierarchy Process (AHP) has previously...

Considerable attention has been paid to relative power that decides the type of buyer-supplier relationship. However, most prior studies have limitations as they have focused only on one focal firm’s (buyer’s or supplier’s) perspective, failing to achieve a more balanced view from both sides of a buyer-supplier relationship. This study proposes a research framework by integrating both the buyer...

In this study, a two-echelon supplier-manufacturer system with finite production rate and lead time is proposed. It is assumed that shortage is not permitted and the lot size of manufacturer (second echelon) is m-factors of the lot size of supplier (first echelon) and supplier can supply the manufacturer’s lot size in several shipments in each cyc...

In this paper, we develop a procedure for selecting a supplier. Suppliers are characterized by their lead time, price and quality (random yield). Each purchased item is acceptable with a given probability and independent of the others. We assume the demands are deterministic with no set-up cost and backordering is allowed. For each supplier, an optimal ordering policy is developed. We prove the...

Robust supplier selection problem, in a scenario-based approach has been proposed, when the demand and exchange rates are subject to uncertainties. First, a deterministic multi-objective mixed integer linear programming is developed; then, the robust counterpart of the proposed mixed integer linear programming is presented using the recent extension in robust optimization theory. We discuss dec...

This paper presents an overview of the SAS® approach to supplier management, focusing on the use of SAS’ wellestablished optimization expertise to aid in selecting and evaluating suppliers. The supplier management solutions are explored individually and are shown in the context of a complete spectrum of SAS supply chain solutions.

Previous academic research on the expansion of dominant retailers such as Wal-Mart has looked at implications for incumbent retailers, consumers, and the local community. Little is known, however, about Wal-Mart’s influence on suppliers’ performance. Manufacturers suggest Wal-Mart uses its power to squeeze their profits. In this paper we study the validity of that claim. We investigate the unde...

The aim of this paper is to identify antecedents to supplier integration in China. A deductive approach was deployed by building on a qualitative pre-study and various strands of SCM literature. All in all, 14 hypotheses were derived and subsequently tested by drawing on an empirical sample collected from 88 manufacturing firms operating in China. The data was then analyzed using partial least ...
