Kapittel II.2: Markov Modelling for Repairable Systems


The aim of ageing management is to ensure safe and cost-effective use of technical equipment throughout the designed or possibly extended lifetime of the system. The purpose of this book is to be helpful in this work. BackgroundThe book is divided into three parts; one general part, the second focusing of the mathematics involved and the third discussing a number of applications.Part one consists of four chapters. In the first Eid, Lannoy & Procaccia are setting the foundation by discussing what ageing is. They present some physical aspects, why the topic is interesting to us and why reliability theory is a useful tool to improve the ageing management. Next Simola, in two sections, discusses what ageing management is and what methods are available to support this. Aspects relevant for ageing and information needs are described. She goes on to discuss, very generally, how to identify ageing components and effects. Further, Simola discusses the basic principles of reliability modelling of ageing, but without going into details of the mathematics. In chapter four Petterson first discusses data for identification of ageing phenomena; what should we look for and how. Bouzaiene-Marle follows with a discussion on how expert judgement can be used in ageing anticipation, and what should be considered in such process. ESReDAESReDA (European Safety Reliability & Data Association) is a European Association established in 1992 to promote research, application and training in Reliability, Availability, Maintainability and Safety (RAMS). The Association provides a forum for the exchange of information, data and current research on Safety and Reliability and a focus for specialist expertise. Editors: Lars Petterson and Kaisa Simola
