%X Decision making1 process is a huge and crucial activity that must be given high attention by decision makers and managers as it affects all business strategies in organizations. As a result of the rapid increasing and sustainable needs of organizations, relationship between organizations and suppliers has become essential to any business. In addition to all obstacles that will face the organization when poor decision is made. Decision makers and managers face challenges when they are about to select suppliers, for procurement of raw material and components for their manufacturing process. This paper presents a new hybrid model which combines Linear Weightage and Analytic Hierarchy Process (AHP) Models for supplier selection process. The final decision from this new approach will guarantee better decisions and provide a robust tool for assisting decision makers and managers to make the right decision and select the most suitable supplier. The proposed model has been applied in a real life example and finally ranking the supplier based on their scores obtained from this new approach. %K Analytical Hierarchy Process; Decision makers; Hybrid model; Linear weightage model; Supplier selection, Hierarchical systems; Managers; Mathematical models; Societies and institutions, Decision making %D 2010 %O cited By 1; Conference of World Congress on Engineering 2010, WCE 2010 ; Conference Date: 30 June 2010 Through 2 July 2010; Conference Code:85243 %J WCE 2010 - World Congress on Engineering 2010 %L scholars849 %C London %T The role of mathematical model in managerial decisions- with special reference to supplier selection %A P.D.D.
