Development of a Framework and Criticality Analysis Model for the Implementation of Reliability Centered Maintenance

Abstract

Reliability Centered Maintenance (RCM) originated to optimize the maintenance process newlineof aircrafts in 1960s for the Boeing Company. RCM started with a comprehensive zerobased newlinereview of necessities of every component in its working context and rapidly it newlinebecame the cornerstone of present maintenance scenario. Today RCM has become one of newlinethe best strategies for maintenance around the globe. RCM is an organized procedure for newlinecreating and enhancing the maintenance necessities of a physical asset in its working newlinecontext to improve the intrinsic reliability by consistently consolidating the ideal use of newlinereactive, preventive, condition-based and proactive maintenance. newlineThe responsibilities of RCM have been expanded from the improvement of maintenance newlineactivities dependent on Failure Mode, Effects and Criticality Analysis (FMECA). newlineLiterature provides the different frameworks with different sets of elements of RCM. newlineMost of the frameworks are dependent on qualitative analysis of the system and newlineimplementation of RCM is limited to criticality analysis using conventional FMECA newlineonly. Applications of conventional FMECA have raised some significant issues for the newlinecriticality analysis. Therefore, there is a need to develop a framework and criticality newlineanalysis model for the implementation of RCM. The objectives of the thesis are: (i) newlineDevelopment of a framework for the implementation of RCM, (ii) Development of a newlinemodel for identification of criticality levels of subsystems/components of a system, and newline(iii) To propose an approach of FMECA for criticality analysis of different failure modes newlineof a system. To achieve the objective of the proposed research, this thesis includes the newlineseven chapters. Some of the salient features of these chapters are described as follows: newlineChapter 1 introduces the research motivation, objectives and methodology of the newlineresearch. The background and introduction of RCM also presented in this chapter. newlineIn chapter 2, comprehensive literature review of RCM is presented to identify the newlineevolution of RCM definitions and
