Abstract

Discrete-event simulation is often considered the method of last resort because of the excessive time needed to develop and debug models, as well as run experiments and analyze results. The Flexible Ada Simulation Tool (FAST), is designed to alleviate these problems through extensive use of Ada design methodology (Ada is a registered trademark of the U.S. Government, Ada Joint Program Office). Object-oriented design permits rapid expansion of language features, including interfaces to data base systems, statistical tools, and graphics packages. Ada exception handling greatly improves the user interface and debugging environment, while Ada tasking provides the user with control of the computer resources. How these features contribute to the reduction of major simulation bottlenecks is explored in this paper. The ease in which FAST has been extended to encompass all facets of computer simulation, from creating models to generating reports, is also demonstrated.
