Abstract
Introduction: Construction projects are one of the most important sectors of the economy of the country, which has a high capacity for job creation. Construction projects as part of a huge and strategic set of construction projects that unfortunately have a large share of work-related accidents due to the lack of attention to safety. One of the most important issues that can contribute to these events in construction projects is the weakness or lack of comprehensive and efficient risk management. The purpose of the present study was to identify and rank safety risks in construction projects with the combined approach of FUZZY FMEA and FUZZY TOPSIS
Materials and Methods: This study is descriptive-survey research in terms of purpose and terms of data collection The research was conducted by case study in the case of Qasrdaria town project in Mahmudabad city in 2015. Data collection was through a field study on the statistical population, including project managers, supervising and executive engineers, and building safety experts. The data were calculated in MATLAB and EXCEL software and the output of FUZZY FMEA and FUZZY TOPSIS methods were analyzed. This method for subsequent stages of risk assessment and risk control based on their priority, as well as cost savings.
Results: The identified risks were given to the building safety specialists in the form of a questionnaire. The most important risks extracted from the FUZZY T.O.P.S.I.S method were related to the colliding crane arm with the building and then slipping and falling off the people from the stair ramp. In the FUZZY F.M.E.A method, the risks associated with falling from the edge of the pit, slipping and falling off the stair ramp, as well as falling from the scaffolding and workstations are the highest.
Conclusion: The most important identified risks in the construction industry based on these two ways are as follows: falling off the edge of a pit, slipping and falling from a stair ramp falling from a scaffold, workstations, colliding of crane arm with the building and slipping and falling people from the stair ramp

Abstract
Introduction: Identifying occupational hazards and managing occupational safety and health risks has been the most important mission and responsibility of the health and safety management system in organizations and adopting coded plans to achieve this is the key to continuously improving this system and promoting it. The aim of the present study was to determine the optimal risk assessment methodology in development projects.
Materials and Methods: This was a descriptive-analytic research In this research, using previous research studies and collecting expert opinions, the most important criteria for selecting a specific risk assessment methodology, and then using one of the three most-used techniques is an important activity in the steel making industry and risk assessment. Then, the decision matrix is based on the strengths and weaknesses of the models. The prioritization of these three methods is done using the hierarchical analysis decision method.
Results: In this paper, five key factors, the degree of application in identifying hazards, usability in different stages of risk assessment, reliability, ease of use, and training needs and costs, are identified as the most important criteria for choosing a risk assessment technique and the FMEA method was considered as the best Risk Assessment Method.
Conclusion: FMEA methodhas been introduced with regard to its capabilities as an optimal risk assessment method for contruction projects.
