Simulation in the next millennium

The paper looks into the future of simulation. The capabilities and features of simulation software of the future are hypothesized, focusing on the major aspects of their use. The features addressed include model building, visualization, output analysis and optimization, integration and the Internet. The discussion of simulation software in the future is closely related to the vision of future applications of simulation. Applications of simulation in the near term future are proposed using examples of advanced applications that are in conceptual stages at present. Applications of simulation in the long term future are also proposed, bordering on science fiction.
