Reliability analysis and maintenance optimization based on advanced prognostics methodologies

Reliability measures the ability of a component or system performing its intended functions, and it is one of the most critical performance measures of engineering systems such as aircraft systems, manufacturing systems and wind power systems. Maintenance optimization aims to improve reliability and reduce the overall cost. In conventional reliability analysis, failure data are mainly analyzed using statistical methods, and reliability performance is estimated for component population rather than individual units. The availability of condition monitoring data, such as vibration and acoustic data, make it possible to obtain a far more accurate reliability prediction for individual components, and there's great potential to subsequently achieve more effective system reliability analysis and maintenance management.
