摘要: 为了对工程系统的运行和维修实施有效的管理,需要对系统关键性能指标进行定量评价和监控。通常,系统全局性能由一个多层级结构的指标体系所描述。层级结构的底层是一列可直接观测的参数或变量,中间层是合成的指标,顶层是服役质量指数或类似的术语(如健康指数)。为明确服役质量指数和性能评价指标体系的含义和用途,完成一个关于质量指数和指标体系的文献综述,并讨论与之相关的研究课题。研究发现,质量指数是一个或多个用于描述系统健康状态的全局的、综合的性能指标,导出质量指数的方法是多准则分析;指标体系和质量指数的主要用途包括性能评估、监控或监管、问题追踪和运维决策。不同于在线监控和故障诊断,基于质量指数的性能监测与追踪通常是周期地完成的,适合于复杂工程系统的整体性能监控和中长期管理。文中所述评的方法和典型案例对复杂工程系统的监管和运维管理具有借鉴作用和参考价值。

Abstract: To effectively manage operations and maintenance of engineered systems, the key performance indicators of the systems should be quantitatively evaluated and monitored. The systems' performances are usually described by a multi-level indicator framework. A set of directly measureable parameters or variables are located at its bottom, the aggregated indicators are in the middle-levels and the overall in-service quality indices or the like (e.g., health index) are at the top. To clarify the meaning and uses of quality indices and indicator framework, a literature review on them is carried out and relevant issues are discussed. It is found that the overall and comprehensive performance of a system is described by one or more quality indices, and the method to derive the quality indices is multi-criteria analysis. The main applications of the performance evaluation framework and quality indices include health evaluation, monitoring or regulation, issue tracking as well as operation and maintenance decisions. Different from condition monitoring and fault diagnosis, the quality-indices-based performance monitoring and tracking is usually conducted periodically and applicable for monitoring and controlling of overall performances of complex engineered systems as well as mid-long term management of the systems. The reviewed methods and typical case studies have reference meaning to the supervising, operation and maintenance management of complex engineered systems.
