Abstract

The worst impact of the pandemic is visible on the industrial sector which was brought to almost shutdown; especially many Indian MSMEs are on the brink of closing down due to huge financial losses. We are now living in a post pandemic world where each small resource matters a lot and whatever we are producing must be very reliable to its intended applications. All the Industries especially MSME around the globe are facing a lot of challenges to achieve better productivity and customer satisfaction due to increasing necessity and demand for more reliable products at minimal cost. This has redefined the importance of reliability engineering and its impact on product/service lifecycles of complex systems and their economics. In the recent past Reliability centered assessments proved itself as one of the most trustworthy strategies not just to prolong the life of complex industrial systems by critical analysis of its repairable & non-repairable sub-systems but also by highlighting the most critical subsystems behind majority of failures. In this article, the aim is to provide a comprehensive state of art roadmap for reliability analysis of complex repairable system which will cover not only the theoretical aspects of Reliability analysis but will be focusing on various system structures and their respective effects of reliability analysis. Later part of the article will discuss a stepwise methodology for effective outcomes which will prove as a guide for practicing reliability and maintenance engineers and decision makers.
