  4. 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
