The failure mode and effects analysis (FMEA) is a widely used analytical technique that helps to identify and reduce the risks of failure in a system, component, or process. One important issue of FMEA is the determination of the risk priorities of failure modes. Risk ranking is produced in order to prioritize the focus on each of the failure modes that are identified. In this study, we applied...

Quadcopters are playing an increasingly important role in a variety of industries due to their numerous advantages over other types aircraft. Additionally, quadcopters susceptible damage, and repair can be costly. On the hand, today, reliability is recognized as critical design feature most industries. A device's one complex issues field engineering since it provides engineers with insight into...

Failure mode and effects analysis (FMEA) is awidely used engineering technique for designing, identifying and eliminating theknown and/or potential failures, problems, and errors and so on from system to other parts. The evaluating of FMEA parameters is challenging point because it’s importantfor managers to know the real risk in their systems. In this study,we used fuzzy TODIM for evaluating t...

Failure mode and effects analysis (FMEA) has been proven to be an effective methodology to improve system design reliability. However, the standard approach reveals some weaknesses when applied to wind turbine systems. The conventional criticality assessment method has been criticized as having many limitations such as the weighting of severity and detection factors. In this paper, we aim to ov...

In this study, we proposed a method to improve the safety level of control software (CSW) by managing CSW’s design information and analysis results, combining failure mode effects (FMEA) fault tree (FTA). Here, CSW is developed using structured methodology. upper stage development process, as input preliminary (data flow diagrams (DFDs) (CFDs)), causes undesirable events are clarified FMEA, cou...

The aim of this paper was the application of the failure mode and effects analysis (FMEA) approach to assess the risks for patients undergoing radiotherapy treatments performed by means of a helical tomotherapy unit. FMEA was applied to the preplanning imaging, volume determination, and treatment planning stages of the tomotherapy process and consisted of three steps: 1) identification of the i...

The purpose of all service institutions, including banks is to provide appropriate services for the customers' satisfaction. In fact, the key to the success of these organizations relates to the customer-orientation and focus on the quality of services. Since the organizations providing financial service, especially banks operate in an environment with indistinct products, their quality service...

The purpose of this study is to determine the type failures, causes, as well efforts and proposed actions that can be taken improve performance pneumatic system CNC milling machines. Failure Mode Effect Analysis (FMEA) method used find priority problems through Risk Priority Number (RPN) for components machine. results critical component analysis were a leakage occurs in valve component, which ...
