Statistical analyses for simulating schedule networks

This paper introduces the stochastic project scheduling simulation (SPSS) system and two additional useful statistical analysis tools. SPSS integrates CPM, PERT, and discrete event simulation (DES) scheduling methods into one system. It can generate a CPM-based deterministic schedule, a PERT-based probabilistic schedule, and a simulation-based stochastic schedule for the project under study. Two additional statistical analysis tools are added to assist users in determining the number of simulation runs needed for a given schedule network and testing the significance of difference between two independent simulation experiments.
