Using the expression way of general event probability to fuzzy event probability, common method of probability can find fuzzy event period risk for fuzzy network planning.

对模糊型网络计划，计算模糊工期风险概率是利用模糊事件概率的普通事件概率表示方法，用常规的概率方法求解。

The importance of fuzzy distance can be obtained by extending the concept of structural importance of bottom event from probability space to fuzzy set, in the light of the concept of fuzzy distance.

利用模糊距离概念，将底事件结构重要度概念从概率空间推广到模糊集中，得到模糊距离重要度。
