A Critical Review of the Literature on Reliability, Availability, and Maintainability Approaches for Complex Systems in Different Process Industries

Abstract

Industrial systems need to run smoothly and efficiently for as long as feasible to provide dependable performance in light of the rising demand for quality. Due to growing expenses, heightened competitiveness, and public expectations, it is imperative to assess these systems' performance while controlling the risk of possible malfunctions. Although it is unfeasible to achieve 100% failure-free operation in production, it is possible to minimize system failures in industrial systems that are repairable. This study examines the different aspects that affect system reliability and availability in process-based industries, with a focus on the Reliability, Availability, and Maintainability (RAM) approach. In addition to outlining procedures for performing RAM analysis, a review of RAM tools, techniques, and methodologies from the previous 20 years helps to clarify dependability and availability in complex process industry systems.
