Safety risk assessment and ranking in the construction projects with F.M.E.A and fuzzy T.O.P.S.I.S

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 are part of a huge and strategic set of civil engineering projects that unfortunately have a large share of work-related accidents due to 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. Methods: 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. This method for subsequent stages of risk assessment and risk control based on their priority, as well as cost savings. The cost and time of construction project implementation are applicable. This study is descriptive-survey research in terms of purpose and terms of data collection. Results: The identified risks were given to experts and experts in the field of building safety during the questionnaire. The most important risks extracted from the FUZZY T.O.P.S.I.S method are the impact of the crane arm on the building and the slipping and falling of the ramp. In the FUZZYF.M.E.A method, the risks associated with falling from the edge of the pit, slipping and falling from the staircase ramp, and falling from the scaffolding and workstations are highest. CONCLUSION: The major identified risks to the construction industry in two ways, including falling from the edge of a trench, slipping and falling from a staircase ramp and falling from a scaffold, workstations, crane arm colliding with the building and slipping and falling from There is a dirt road on the ramp.
