【摘要】 简述了对故障树程序的移植和改进。这些改进是:增加了相关割集重要度计算、割集数大于某值的截断、最小割集故障率计算、相关割集的排队、最小割集故障率排队、以及当割集故障率小于某一值割集的再次截断等功能。计算结果表明,使用改进后的程序在给出同样结果的条件下可大大地节省计算时间。更多还原

【Abstract】 The transplanting and improvement of a fault iroo program are introduced. The main improvements are adding the calculation importance of interrelated cutets, cutting the number of cut-set when its value is greater than the given value, the failure probability of a minimum cut-set, queuinj of the interrelated cut-sets and recutting function when the failure probability of a cut-set is less than the threshold .The calculated results show that it would give the same results and the computing time would be greatly saved by us this improved program.更多还原
