Risk is the possibility of the occurrence of an event outside of which every activity that is likely to be detrimental is carried out by humans. In the Nangarasong Steel Frame construction project in Flores district, there is uncertainty which will create a risk that can encourage the project and can affect the potential for work accidents. Uncertainty factors can cause risk in an activity that has an impact on decreasing labor productivity, risk of cost, time, and damage to design or technology. To reduce these adverse impacts, a risk management system is needed, which includes analysis, analysis, and monitoring of risks that may occur. Risk management makes an integrated effort to manage the risk of work accidents by using the FMEA (Failure Mode And Effect Analysis) method. All construction projects that may experience accident risks are identified and analyzed for the severity with FMEA, from the results of which the causes and impacts of the work accident risks will be sought. After knowing and the impact of the risk of work accidents, the next action on the risk of work accidents that result.

Construction projects in Iraq face many dangers that cause exceeding the estimated cost of the project and not completing the project on time, and since the risk management process in construction projects is of great importance in controlling and reducing the impact of risks in construction projects, so it is necessary to identify these risks and evaluate them correctly in order to increase accuracy and the health of the subsequent stages of the risk management process in construction projects. This paper aims to identify the most important risks in construction projects in Iraq and to conduct a qualitative assessment of the identified risks and arrange them according to their importance. The researcher adopted the questionnaire method as a tool to determine the risks and used the technique of probability and effect matrix to conduct the qualitative assessment of the identified risks. The study found that there are 48 risk factors that constitute the most dangerous factor in construction projects in Iraq, and 10 of the determining factors were within the high level of risk, and at the forefront of which was the inability of the owner to finance the project.

The paper aims at presenting the FMEA method based on the fuzzy technique, representing a new approach to the failure analysis and its effects on the observed system. The FMEA (Failure Mode and Effect Analysis) method has assigned the risks a coefficient i.e. a numerical indicator that very clearly defines the degree of risk. The risk is calculated as a mathematical function of RPN which depends on the effects S, probability O that some case will lead to a failure and to a probability that a failure D can not be detected before its effects are realized. RPN = S O D. The FMEA method, based on the fuzzy logic, makes a more reliable evaluation of the observed system failures possible.

This research is aimed at utilizing failure mode and effect analysis (FMEA) which is a reliability analysis method applicable to rotary injection pump design. In traditional FMEA, Risk Priority Number (RPN) ranking system is used to evaluate, the risk level of failures to rank failures and to prioritize actions. RPN is obtained by multiplying the scores of three risk factors like the Severity (S), Occurrence (O) and Detection (D) of each failure mode. RPN method can not emphasise the nature of the problem, which is multi-attributable and has a group of experts' opinions. Furthermore, attributes are subjective and have different importance levels. In this paper, a framework is proposed to overcome the shortcomings of the traditional method through the fuzzy set theory. Two case studies have been shown to demonstrate the methodology thus developed. It is illustrated a parallel between the results obtained by the traditional method and fuzzy logic for determining the RPNs. We expect that fuzzy FMEA model will assist FMEA team in assess and rank risks more precisely compared with risk assessment model of method.
