Reliability, Availability and Maintainability Approaches for Complex Systems in Various Process Industries: A Critical Literature Review

Abstract

With increase in the demand and requirement of quality the industrial systems should work smoothly and efficiently for maximum possible time and should have infallible performance i.e. the reliable operation. Thus it is important to evaluate perfoWith increase in the demand and requirement of quality the industrial systems should work smoothly and efficiently for maximum possible time and should have infallible performance i.e. the reliable operation.
