Describes AT&T Istel's WITNESS visual interactive simulator. WITNESS is a comprehensive discrete-event and continuous-process simulator. It is designed to allow a person who is knowledgeable about the process under study to rapidly, incrementally and accurately build, debug, validate, verify and exercise complex models. The benefits of using WITNESS are described and illustrated by explaining the steps required to build any WITNESS model and then, at a more advanced level, by creating a sample model.
