FMEA is a useful tool that helps to find possible flaws in a system or element, mainly in the design phase. But it is a mere document that has no further ''direct'' use than the observation. Mapping all this knowledge into a Bayesian Network would make it possible to use the information in further ways, like software applications for maintenance. A good FMEA has the necessary features to build ...

The goal of quality and reliability systems is the same-to achieve customer satisfaction. Quality and reliability are synonymous. A system cannot be reliable if it does not have high quality. Likewise, a system cannot be of high quality if it is not reliable. The quality performance of a firm is often assessed by the reliability of the firm's equipment or machinery. If a system is unreliable, i...

An ontology for representing operating, safety and control procedures is proposed in this paper that supports diagnosis based on following these procedures and combining observed malfunctions with Failure Mode and Effects Analysis (FMEA) information. The procedure ontology is defined within interconnected components of the process plant, diagnostic analysis (where the FMEA is described) and pro...

background and objectives: surgical cancelation is a significant source of time and resource waste, patientsafety risk, and stress for patients and their families. in this study, a risk management-based approach is developed to prioritize factors contributing to surgical cancellation. methods: factors leading to surgical cancellation were comprehensively classified based on literature review.a...

Abstract: FMEA is one of the most used methods to support risk analysis in business processes. Nonetheless, this method has some limitations, including use only three decision criteria, whose weights are not considered. With objective adding new features FMEA, studies combine it with multicriteria methods. This study proposes a model based on and Fuzzy TOPSIS prioritization industrial productio...

Functional safety standards (ISO 26262, IEC 61508) require a safety life cycle which demands additional design and engineering tasks to be managed. This paper addresses how the existing FMEAs have to be extended and refocused to address and overview signal paths throughout the system. The safety standards require to classify signals with a SIL (Safety Integrity Level) and the higher the SIL the...

Failure Mode and Effects Analysis is widely used in engineering hardware systems to help in understanding the effects of potential failures and the faults that cause them to occur. The analysis is iterative leading to improvements in the design until the risks associated with potential failure modes are reduced to an acceptable level. Interest in applying the technique to software has increased...

Failure mode and effects analysis (FMEA) is a method based on teamwork to identify potential failures and problems in a system, design, process and service in order to remove them. The important part of this method is determining the risk priorities of failure modes using the risk priority number (RPN). However, this traditional RPN method has several shortcomings. Therefore, in this paper we p...

Health care failure modes and effects analysis (FMEA) is a widely used technique for assessing risk of patient injury by prospectively identifying and prioritizing potential system failures. In this study, we conducted in situ simulations at a major suburban hospital as a novel method to discover latent conditions and active failures and to prioritize these based on the potential severity of ri...

PURPOSE Failure modes and effects analysis (FMEA) as defined in TG-100 has become a popular concept throughout the radiotherapy community. This risk mitigation technique involves detailed process mapping, analysis, and ranking of potential errors by means of a subjective, ordinal scoring system. This study aims to reduce the subjectivity of FMEA severity scoring for IMRT delivery by providing q...
