Abstract
If the activity-completion-times of a project-network are random variables the project-completion-time is a random variable the distribution function of which is difficult to obtain. Thus, efforts have been made to determine bounds for the mean and bounding distribution functions for the distribution function of the project-completion-time some results of which are shortly surveyed. Then, a new approach using stochastic programming for a cost-oriented project scheduling model is presented. Generalizing a well-known Fulkerson-approach planned execution-times for the random activity-completion-times are computed where nonconformity with the actual realizations impose compensation costs (gains). Taking into consideration a prescribed project-completion-time constraint the expected costs for performing the activities ac-cording to the planned executions-times are minimized. A solution procedure is described which constructs a sequence of nonstochastic Fulkerson project scheduling models. It is demonstrated by means of an example.
