面 向 复 杂 系 统 健 康 评 估 的 若 干 思 考

With the increasing system complexity in various engineering applications，greater demands are being placed on the reliability and safety of these systems. A kind of more comprehensive requirement called“health”has been naturally put up beyond reliability and safety. Consequently，Prognostics and Health Management（PHM）for complex systems has naturally become a hotspot in systems engineering. Moreover，it has been applied in many areas，such as aerospace，machinery，and power electronics. This paper summarizes and proposes a framework for the health assessment of complex systems，which consists of four aspects：data acquisition，data processing，health assessment，and health prediction. At last，the prospect view of health assessment is presented，and a system-leveled open-source project，namely OpenHA（Open Health Assessment）is suggested.
