• The achievements achieved in the study are presented as follows : ( l ) to the distribution of construction duration of the pert network , even though every activity duration obeys normal distribution , it is failed to be proved to be in the obedience with normal distribution strictly . however , if there - are a lot of activities in a path of the pert network , for instance , more than 20 activities , without reference to the normal distributions - distribution or triangle distribution which activities duration obeys , the construction duration approximately obeys the normal distribution when the form of distribution is not partiality seriously
  通过本文的研究取得的新成果有： ( 1 )对pert网络施工工期的分布，即使每一活动持续时间服从正态分布，也不能证明其严格服从正态分布，但当pert网络线路上的活动较多时，如超过20项，不论活动持续时间服从正态分布、分布，还是三角分布，当偏态不十分明显时，则工期近似服从正态分布。
• By analyzing group of data , appropriate statistics , such as distribution and average of activity duration , distribution and average of project duration , etc were gained which can be used to determine a reasonable and executable schedule considering influence of random factors
  运用这些模型在计算机上进行仿真试验，得到一组工作时间参数的样本值，通过对这组样本值的统计分析，得到在随机因素影响下工作持续时间的变化趋势和平均值、项目工期的变化趋势和平均值等参数值，从而为科学地进行进度管理提供依据。
