ProbSched is implemented in Microsoft Visio and is a shell for Stroboscope's simulation engine. It is entirely self-contained and learning and using ProbSched does not require any knowledge or use of Stroboscope directly. Probabilistic scheduling networks in ProbSched are built using custom drag-and-drop graphics that do not require any programming. The simulation of ProbSched models produces automatically (a) textual and graphical output to indicate the criticality of each activity, (b) statistics about the early and late times and floats of all activities, and (c) statistics about the overall project duration. It is also possible, if so desired, to augment ProbSched models with standardized easy-to-use Stroboscope statements that provide additional project control and statistics.

ProbSched is installed with Stroboscope and can be launched by selecting ProbSched from the Stroboscope program group.
