This paper provides simulation practitioners and consumers with a grounding in how discrete event simulation software works. Topics include discrete event systems; entities, resources, control elements and operations; simulation runs; entity states; entity lists; and entity list management. The implementation of these generic ideas in AutoMod, SLX, and Extend is described. The paper concludes with several examples of "why it matters" for modelers to know how their simulation software works, including coverage of SIMAN (Arena), ProModel, and GPSS/H as well as the other three tools.
