性能指标是系统的重要质量指标,它的满足程度如何将直接影响系统运行的经济性和有效性。以前,对系统运行过程中普遍存在的功能退化问题没有给予足够的重视,本文针对这一状况,应用模糊集理论,将性能指标模糊化,对系统功能问题进行了初步探讨。重点研究了系统性能指标模糊概率的求解问题,给出了一种较为通用的分析处理方法,为系统功能退化问题的深入研究提供参考。
The performance index is an important quality index of the system, and how its satisfaction will directly affect the economy and effectiveness of the system operation. In the past, there was not enough attention paid to the function degeneration problem that existed in the operation of the system. In this paper, fuzzy sets theory was applied to obscure the performance indexes and the system function problems were discussed preliminarily. Focusing on the problem of solving the fuzzy probability of system performance index, a more general analysis and processing method is given, which provides a reference for the further study of system function degeneration.
