Review on Verification and Validation technology in integrated health management system

Verification and Validation (V&V) technology has been identified as a key step in quantifying and building confidence before integrated health management (IHM) system deployment to inform about equipment or component's health status and to support operational and maintenance decisions. However, due to generally no rigorously universal methods and no statistically adequate data available, V&V technology remains a challenging open problem. The recent developments appeared in academic journals, conference proceedings and technical reports for V&V technology in IHM field are systematically reviewed in this paper, focusing on V&V definitions and standards, V&V metrics, and V&V methods as well as the future development trends and challenges of V&V technology.
