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...

BACKGROUND A multidisciplinary and multi-institutional working group applied the Failure Mode and Effects Analysis (FMEA) approach to the actively scanned proton beam radiotherapy process implemented at CNAO (Centro Nazionale di Adroterapia Oncologica), aiming at preventing accidental exposures to the patient. METHODS FMEA was applied to the treatment planning stage and consisted of three ste...

PURPOSE To develop and implement a failure mode and effect analysis (FMEA)-based commissioning and quality assurance framework for dynamic multileaf collimator (DMLC) tumor tracking systems. METHODS A systematic failure mode and effect analysis was performed for a prototype real-time tumor tracking system that uses implanted electromagnetic transponders for tumor position monitoring and a DML...

Based on Boeing 737-900ER unscheduled removal data of pitot probe 0851HT-1 January, 2020 to November, 2021 found 14 for with one the defect is “pitot light on”. This indicate that there a problem component and can disrupt pilot delay aircraft. Knowing result failure identification type be aim this research. Analysis using Failure Mode Effect used identify modes, causes effects failure, severity...

Failure modes and e€ects analysis (FMEA) is a quality improvement and risk assessment tool commonly used in industry. It is a living document used to capture design and process failure information. However, the traditional FMEA has its limitations in terms of knowledge capture and reuse. In order to increase its e€ectiveness, much research has been carried out to ®nd an e€ective way to provide ...

FMEA has been used for several years and proved its efficiency for system’s risk analysis due to failures. Risk priority number found in FMEA is used to rank failure modes that may occur in a system. There are some guidelines in the literature to assign the values of FMEA components known as Severity, Occurrence and Detection. This paper propose a method to assign the value for occurrence in mo...

greater levels of complexity in tunnelling with tunnel boring machine (tbm) allow higher chances of failures that may increase the potential hazardous risks. this paper presents the results of a study on tbm reliability using risk analysis. machinery failure mode and effect analysis was applied to analyze the risks of a tbm using qs9000 and sae.j1739 recommendations. for this purpose, 48 failur...

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 ...

The Failures Modes and Effects Analysis (FMEA) method is applied to different activities in order improve production processes. Its operation allows analyze failure modes, describe their effects, identify causes design control systems. In addition assessing these factors, it contributes the formulation of various improvement actions; however, has an intrinsic weakness when comes prioritizing ac...
