Proper risk identification and management is inevitable for managers, especially in basic projects of the country. It is impossible to implement projects in a risk-free environment, and the consequences of the project will affect the project’s three main objectives (time, cost, quality) and usually impose costs for the project. Therefore, considering that the risks of a project are not eliminable but they are distributable, to optimize the objectives of a project, important and critical risks of the project should be identified and ranked, so that we can assign each risk to the employer or the contractors and monitor the consequences. Considering railways of Iran need for maintaining and repairing locomotives, this study introduces a fairly complete set of criteria (probability of occurrence, risk effect and probability of discovery) using multi-criteria decision-making technique and SAW method had been proposed to assess all important risks related to repair- maintenance depot of Mashhad Railway. In this regard, two questionnaires were sent to five experts of Mashhad railway and they evaluate and rank the identified risks through the SAW method, and finally, the risk of delay in construction (lack of comprehensive management system) identified as the most critical risk. Then the best response to the most critical risk was identified through the AHP model using the other questionnaire, which is “employing professional project managers and counselors familiar with management techniques.
