摘要
针对传统的二元逻辑无法定量描述单元部分失效对系统整体性能的影响的问题,采用模糊数运算方法,对部分失效条件下的NPP典型系统性能进行了定量计算;并将该方法与模糊综合评估方法进行了比较,后者需定量确定权重系数,增加了结果的不确定性,因此前者计算结果可信度更高.
The effect of components＇ partial failure on system performance can not be quantitatively calculated by traditional binary logic. Fuzzy logic calculation is used in the paper to calculate the effect of partial failure on system performance and is compared with the fuzzy comprehensive evaluation. The latter needs quantitative weigh and the uncertainty increases. Therefore the result of the former is more creditable.
