An approach to pert: application of dirichlet distribution

Abstract

In this paper the important role of the Dibichlet distribution for the Pert problem is motivated. With the help of an inequality for the Dibichlet distribution, the upper bound of the completion time will be given at prescribed probability level.

Keywords:
