Network‐scheduling techniques are used extensively to determine a project's duration. Two of the most popular techniques are the critical path method (CPM) and the probabilistic evaluation and review technique (PERT). Only one of these techniques, PERT, includes a capability to evaluate the risk in the duration of a project. But, PERT has some inherent limitations which affect the user's ability to effectively evaluate risk or variability of project duration. Computer simulation is a way to overcome the limitations of CPM and PERT. This paper describes a method to simulate schedule networks using an existing simulation package called cyclone . The correspondence between a CPM network and a cyclone network is developed and an example of simulating a small network is presented. Computer output and recommended improvements are discussed.
