Reliability is a critical measure of performance of engineering systems such as spacecraft, telecommunication networks, transportation vehicles, petrochemical refineries, and nuclear reactors. Conventional reliability analysis methods are limited by its fundamental assumption that both the system and its components can be in one of only two possible states: working or failed and the statistical approach used to estimate the life of running equipment. This research program aims to develop multi-state reliability models and methods and condition based reliability analysis approaches for reliability enhancement of engineering systems.

可靠性是衡量航天器、电信网络、运输车辆、石化炼油厂和核反应堆等工程系统性能的重要指标。传统的可靠性分析方法受到其基本假设的限制，即系统及其部件都可以处于两种可能的状态之一：工作或故障，以及用于估计运行设备寿命的统计方法。本研究旨在发展多状态可靠性模型和方法以及基于条件的可靠性分析方法，以提高工程系统的可靠性。
