Failure mode and effects analysis (FMEA) is a widely used, powerful tool to identify assess potential failure modes in products make more reliable. Due the complexity of lack knowledge, FMEA involves many uncertainties practice. In previous studies, numerous modified methods based on fuzzy logic Dempster-Shafer (D-S) evidence theory have been employed address these uncertainties. These studies ...

BACKGROUND The aim of blood transfusion risk management is to improve the quality of blood products and to assure patient safety. We utilize failure mode and effect analysis (FMEA), a tool employed for evaluating risks and identifying preventive measures to reduce the risks in blood transfusion. STUDY DESIGN AND METHODS The failure modes and effects occurring throughout the whole process of b...

Abstract Failure mode and effect analysis (FMEA) is a systematic approach for identifying potential failures before they occur, with the intent to minimize the risk associated with them. It has been widely used in the various manufacturing industries as a solution to reliability problems. As the importance of the service sector is increasing, however, it has been recently extended to some appli...

Failure Mode Effect Analysis (FMEA) is one of user friendly and handy tool available in the hands of the process industries to identifying and eliminating the potential failures in systems, processes and designing. In this FMEA method prioritization of the failure modes are based on Risk Priority Number (RPN). This RPN can be calculated by multiplying the scores of various risk factors and cate...

Failure mode and effects analysis (FMEA) is a popular and useful approach applied to examine potential failures in different products, designs, processes, and services. As a vital index, the risk priority number (RPN) can determine the risk priorities of failure modes by some risk factors such as occurrence (O), severity (S), and detection (D). However, in FMEA, the traditional risk priority nu...
