Abstract

Simulation software is changing. Within the past several years, significant developments in simulation software have taken place: 1. New simulation languages have been developed. 2. New software packages have been developed for use in conjunction with simulation (for purposes other than building models, perse.) 3. New features have been added to existing languages. 4. Vendors new to the simulation community have marketed implementations of existing software packages. 5. Simulation environments, comprising integrated collections of simulation software tools have been built. As a consequence of these developments, those readers whose perceptions of simulation software are several years old should consider themselves out of date. Those readers whose perceptions are five or more years old should consider themselves extremely out of date. Furthermore, enormous amounts of time and energy are presently being expended on research and development of simulation software. Thus, we can expect dramatic changes to take place in the near future. Simulation software of the 1990's will be as far removed from present software as present software is removed from building models "from scratch" in languages such as Fortran. This paper, a tutorial, summarizes the present state of simulation software, identifies pressures for changes, and describes an emerging consensus on the major characteristics of simulation software of the future.
