Asset health management system design

With the growing use of complex systems, there has been considerable interest in the development of systems which can diagnose failures and reduce asset maintenance downtime. Nowadays many complex systems have stringent requirements for safety, reliability, availability, maintainability and security e.g. aircraft, nuclear power plants and spacecraft [Soderholm, 2006]. The concept of Integrated Vehicle Health Management (IVHM) was first created by NASA and looks at complete health management solution and addresses infrastructure assets as well as moving vehicles. An IVHM System is made up of different building blocks such as sensors, fault diagnosis and prognosis systems and communication links. It needs to have a rigorous business case representing the diverse stakeholder requirements. This paper explains the context of asset health management and the factors that need to be considered in design and the conceptual IVHM Design System.
