Summary of Content

This module aims to provide a comprehensive introduction to the theory and practice for Reliability Availability and Maintainability.


Basic reliability model and concepts: Introduction, histogram, probability density function, cumulative distribution function, Basic concepts of probability theory and distributions, Causes and types of failure. Definition of reliability, maintainability, availability, failure probability, reliability and hazard rate function, MTBF and MTTR, bath tub curve. Constant failure rate model: Exponential reliability function, failure modes, applications. Time dependent failure modes: Weibull distribution, normal distribution Reliability of systems: Serial configuration, parallel combination, combined serial- parallel systems. Maintainability: Analysis of downtime, repair -time distribution, stochastic point process, reliability under preventive maintenance Availability: Concepts and definitions, availability assessment , Optimal replacement decision models: Models for minimization of total cost, Models for minimization of downtime. Optimal Inspection decision models: Models for maximization of profit, Models for minimization of down time.

Learning Outcomes

On completion of this module the student should be able to:1. Apply the concepts of probability theory and distributions (AM1).2. Evaluate reliability and hazard rate function, MTBF and MTTR (AM1)3. Evaluate reliability maintainability and availability of a simple plant component and system (AM1, AM5). 4. Apply mathematical models for optimal replacement and inspection techniques (AM1, AM5)

Teaching / Learning Strategy

Class room lectures, seminars, guest lectures and case studies for exposure to process equipment maintenance. Tutorials will be used to reinforce the module material discussed during lecture sessions. It also serves as a platform of technical discussions to clarify any queries that arise from directed studies.
