This research deals with new style to find project completion total time, the style is hybrid Bayesian network which is considered as expanded to probabilistic PERT networks, since both styles assuming that time is a random variable, the styles depend upon priority between activities, there is a frequent conditional relation between them, the accomplishing result depends upon the proceeding one and will influence to the next one, so we have to find the conditional distribution for each stage of project, and how to find the marginal function, to get expected time for it. There is a practical application made in “Mild industrial company/ the refrigerators projection factory ASHTAR Refrigerators No.9 is chooses for application.
