摘要
系统状态评估是系统可靠性工程中的一个重要课题。针对系统状态评估的一般特点,基于评估对象各项指标和评估基准之间的广义权距离,提出了一种系统状态的评估方法。通过算例可看出,该方法可简便有效地对待评价的同类型多系统状态进行同时评估,克服了传统系统状态评估中的逐一系统评估的繁琐,为系统状态评估提供了一种新方法。
The assessment of systems＇ state is one of important problems in the systems reliability engineering. According to the general characteristic of systems＇ state assessment, this paper presented a method for assessing systems＇ state based on the generalized weighted distance between the values of evaluated systems＇ indices and their standard values. As may be seen in an illustrative example, this method can be used to assess conveniently the current state of several systems with the same style simultaneously, to overcome effectively the limitation of traditional methods in which only one system can be assessed in one time. And it can be looked as a new method for systems state assessment.
