Fuzzy Logic Approach For Medical Equipment Supplier Evaluation and Selection

Abstract

One of the most critical activities in the management of purchasing process is supplier selection which is a decision making activity characterized by being a multi-criteria based activity. This paper proposes a multi-criteria fuzzy based system to create a short listing of the most suitable suppliers. Only the members of this short listing would be allowed to request for offers in a tender. The proposed system uses three main criteria and twenty sub-criteria. Dataset collected from five different companies is used to validate the system against experts’ opinions. Results show the robustness of the proposed system in creating a short listing for the most suitable medical suppliers with an average error of 4.45 ± 4.06.
