摘要：

For a better estimation of the mean and variance of PERT activity time, we propose using one more subjectively estimable parameter. Two likelihood-ratiosare suggested and their error tolerance ranges are analyzed which provide the mean and variance with less errors than the PERT approximations. © 1990 Taylor & Francis Group, LLC.
