A supply chain is a network of facilities for procuring raw materials, transforming them into intermediate goods and then final products, and delivering them to customers through a distribution system. This paper presents an empirical investigation to measure the performance of a hospital based on the implementation of supply chain operations reference (SCOR) method. The proposed model of this paper considers five criteria including reliability, responsiveness, agility, costs and assets in one of Iranian hospitals and computes the performance of four important departments including dentistry, radiology, pharmacy and laboratory. The proposed model of this paper uses analytical hierarchy process to assign weights for all criteria to measure the overall performance. The result of this survey indicates that reliability is the most important factor in measuring the performance of medical centers.
