【摘要】 根据建设工程的不确定性特征,针对不确定性网络计划,运用模糊理论建立了工序作业时间的模糊隶属函数;并由此计算出工序作业时间的模糊概率及模糊均值和方差,在求得总工期的分布函数之后,计算了在计划工期内完工概率和按照期望的完工概率下的持续时间;最后,运用PERT验证了新方法的正确性。更多还原

【Abstract】 Construction project has the character of uncertainty.This article built fuzzy membership Function for the duration times of the procedures in the uncertain network planning with fuzzy theory for the first time,then calculate the fuzzy possibility,average value and variance of every procedure,after calculate the distribution of the total duration,we can calculate possibility in the planned fulfill time and the fulfill time under planned possibility,at last using PERT validated the correctness of the new method.更多还原
