Abstract: 

Background and Objective: Organizations, manufacturing and nonmanufacturing companies, as well as development units are always associated with incidents and the need for proper risk assessment. The subway construction project is one of the operations, which often entails accidents given its nature and requires special attention. As indicated in the risk definition, risk is always associated with uncertainty. Accordingly, it should be noted that the implementation of risk assessment calculations should be consistent with the principles that could cover this uncertainty. One of the most prominent methods in risk calculation is the use of fuzzy logic that can provide an appropriate response, if accompanied by expert opinions, to estimate the probable risk of accidents.
Materials and Methods: In this study, first, the existing occupational hazards in the subway construction projects were identified. Then, the prioritization and ranking of the identified hazards were performed based on their degree of importance using the fuzzy hierarchical analysis. Finally, the ranking of the safety risks of the subway construction was accomplished by means of the fuzzy hierarchical analysis.
Results: Accrding to the results, the main risk factors of the underground operations included collapse during drilling, collision of machinery with manpower, shotcrete hazards, and leakage of surface water and groundwater.
Conclusion: The present study is the first attempt focusing on the development of a new model to calculate the probability of event incidence. Effective measures can be taken to reduce the risk of a project by eliminating the high risk factors.
