A fuzzy risk-assessment model for maintenance of medical devices based upon OWA operator

Medical equipment maintenance program for its association with the health care issue is of particular importance. Disregarding the maintenance program even in the general medical equipment such as sphygmomanometer can lead to incorrect diagnosis and prescription of treatment, and even fatal results. Unfortunately, the maintenance program based upon periodic inspection or a preset schedule, is insensitive to the type of equipment, operating environment, risk, etc. Which can lead to failure to achieve the expected result. On the other hand due to constraints in financing capacity, physical infrastructure and human resource capability, Prioritize of medical equipment maintenance program based upon the risk has high importance for health centers. In this paper we have introduced the application of Ordered Weighted Average operator for aggregation of different parameters for calculating of Risk priority number (RPN).
