EVALUATING THE SUPPLIERS BASED ON A HYBRID APPROACH OF EINSTEIN CHOQUET INTEGRAL AND PROMETHEE II WITH RESPECT TO SCOR METRICS (CASE STUDY: MEDICAL LABORATORY

Supplier evaluation is one of the most important activities in supply chain management which can effectively contribute to the organizational performance. In the same vein, evaluating the suppliers of healthcare services has great significance. This study aims to develop an approach for evaluating the suppliers of medical laboratory equipment based on the performance attributes of supply chain operations reference (SCOR) model by considering their performance in delivery, cost, and quality dimensions. The required data for this research has been collected by interviewing the professionals and distributing questionnaires among the medical laboratory experts working at the hospitals in district 12 of Tehran. In order to simulate the fuzzy mechanisms of human thinking, a group decision-making model has been developed by using the triangular intuitionistic fuzzy numbers and the experts' opinions have been aggregated and analyzed by utilizing a combination of performance ranking organization method for enrichment evaluation (PROMETHEE) II method and fuzzy Einstein Choquet Integral geometric operator. Also, by comparing the results obtained from the proposed approach with the results obtained from the simple PROMETHEE II method, the high accuracy of this approach has been confirmed.
