摘要
The original PERT technique assumes beta distribution for the activity durations. The developments of the past decades have partly refuted this concept; and many different distributions have been introduced. In our research, various distributions (uniform, triangular, beta) are applied in case of closed large-scale infrastructure projects. In this paper, the possible effects of these distributions on the project duration are investigated. It is shown that the use of different distributions with the same three-point estimation has a smaller effect on the project duration than a 10% difference in the values of the three-point estimation.
