Abstract

Failure Modes and Effects Analysis (FMEA) is a software application that mitigates environmental hazards during the design stage. Even though many companies use the current FMEA approach, it has several limitations and drawbacks. Risk is quantified using the Risk Priority Number (RPN), a function of incidence, severity, and detection difficulties. Measuring the intensity and complexity of identification is very personal; there is no standard scale. RPN is similarly a product of ordinal; hence, it is useless as a measure. This study discusses the drawbacks of the manual and FMEA approaches to machinability’s, such as inner diameter over and undersize, collar thickness, and depth oversize, which assesses risk based on cost and time. Life Expense PFMEA helps assess and select design choices to minimise a system's life cycle expense. The cost-based FMEA accounts for uncertainty in the following areas: detecting duration, repair moment, frequency, delay, unplanned downtime, and modelling complicated situations. A case study of a large-scale particle collider demonstrates the advantages of a proposed technique in projecting product lifecycle breakdown cost, quantifying risk, and scheduling preventative, planned maintenance, all to increase up-time.
