Hierarchical event graphs are an easy way to build special purpose simulators. At the lowest level, event graphs are created to represent particular components of the system being simulated; steps in a process flow, or hyper-events. These low-level graphs can then be viewed as different classes of vertices that make up the next higher level graph. A special purpose simulation toolkit is thus developed. Three very different types of hierarchical event-graph simulation toolkits are discussed in this article: a Petri net simulator that is used to teach the activity-scanning approach to simulation modeling; SIMAN and GPSS network simulators that are used to teach process interaction modeling and introduce these languages; and an industrial process simulator called QUALPLAN that is used for planning quality inspection systems.
