Major infrastructure projects are always at risk. The success of these projects depends on the proper management of these risks. Power plants are also one of the infrastructure projects that play a major role in economic development. Due to features such as uniqueness, complex technical and organizational processes, the need for special equipment, etc., these projects are associated with many uncertainties and risks, which often lead to significant deviations from the goals set for the project. Therefore, the basic requirements of these projects are effective risk management. Identifying and evaluating risk are among the most important steps in risk management. Failure to perform any of the steps will result in risk management and misleading the risk management team and waste of resources of the organization.
Therefore, In this paper, a hybrid model was proposed to assess the risk of power plants projects. At first, 34 risks were identified in four environmental, economic, social and technical sectors. Unlike other classic risk assessment methods that assess only two criteria for the probability of occurrence and severity of the effect, the identified risks are identified by using the failure mode and impact analysis in Fuzzy FMEA (Fuzzy FMEA) prioritization and critical risks. Then, to evaluate the impact of other criteria on the objectives of the project and to consider the interplay of these criteria with each other, the hierarchical structure of the topsis was used. The results show that the proposed model is appropriate for real-world issues in ambiguous and uncertain situations.
