Supplier selection has received extensive attention in supply chain management. Yahya et al. (J. Oper. Res. Soc. 50 (1999) 916-930) integrate a collaborative purchasing programme where one of the aims is to select suppliers. They illustrate a new approach based on the use of Saaty's analytic hierarchy process (AHP) method that was developed to assist in multi-criteria decision-making problems. In order to decide the total ranking of the suppliers, we compare the weighted sum of the selection number of rank vote, after determining the weights in a selected rank. This investigation presents a novel weighting procedure in place of AHP's paired comparison for selecting suppliers. It provides a simpler method than AHP that is called voting analytic hierarchy process, but which does not lose the systematic approach of deriving the weights to be used and for scoring the performance of suppliers.
