Failure to define the indicators and sub-indicators for measuring the performance of Repair and Maintenance (R&M) activities is one of the significant problems in buildings. Evaluation of the R&M system in a building is one of the key factors to improving the quality of R&M steps. Therefore, to implement appropriate strategies, the criteria affecting on R&M system must be identified. Also, choosing the proper net policies is a strategic decision making problem that effectively reduces the cost and longevity of buildings. In this research, using the experts’ opinions and the Delphi method, the indicators and sub-indicators affecting on R&M system were identified, and those indicators were graded by using the decision tool. The existing buildings in Karaj city were then considered as a case study to evaluate the system. The results showed that the safety index has a highest grade according to the experts’ opinion, but by reviewing the results of case study, this rank was assigned to health criterion. Then, using the SWARA technic, the most critical policies affecting building R&M are identified among Emergency Maintenance (EM), Breakdown Maintenance, Corrective Maintenance (CM), Preventive Maintenance (PM), Predictive Maintenance (PdM), Total Productive Maintenance (TPM), Proactive maintenance. Using the VIKOR method and the results of both approaches showed that Corrective Maintenance (CM) and Breakdown Maintenance (BM) policies are the best for buildings’ R&M policies.
