摘要
为了能在故障树分析中合理界定底事件的发生概率 ,本文对事件的模糊性进行了分类分析 ,并就事件概念的模糊性和相关数据的精确性 ,提出了三种可能的组合情况 。
In order to confirm the Event Probability during fault tree analysis( FTA), the classifying analysis of event fuzziness was made ,and three possible composite cases for the fuzziness of event comcept and the accuracy of relative data were advanced. Both the analysis method and the calculation formulas of Event Fuzzy Probability in different cases are also given out.
