Design considerations of computer-aided RCM-based plant maintenance management system

Abstract

This chapter discusses the designing of computer-aided reliability-centered maintenance (RCM)-based plant for the maintenance of management system. The idea of integrating RCM process with the computerized maintenance management system (CMMS) is studied, because the maintenance strategies are dynamically changing throughout the plant lifecycle. The integrated solution is discussed in two folds: (1) information, where plant-design model is obtained from the plant-design environment while plant operational information is acquired from the operational systems and (2) process logic where hazard and operability study (HAZOP), failure mode and effects analysis (FMECA), and Fault Tree Analysis (FTA) are utilized to analyze and assess all failure types in quantitative manner while combined monte carlo, genetic algorithm, and weibull probability distribution functions (PDF) are employed to optimize the maintenance tasks. The activity and functional models of the enhanced RCM process are developed. Modifications to the different modules of CMMS are proposed.
