** (.):** For a generalized stochastic network schedule with a given multi-dimensional distribution of arcs passage time we propose the analytical- and simulation-based routines to calculate the probability of all critical paths, the distribution function and the first two moments of the project completion time. The routines are based on a specially constructed system of inequalities binding the task completion times.
