Requirements for interactive simulation systems

Abstract

The evolution of computer hardware and operating systems has made feasible simulation research which benefits from the many advantages of computing in an interactive environment. A general discussion of modelling considerations and the features of discrete simulation systems is followed by a set of basic requirements for interactive simulation languages and monitors. Systems designed for simulation of particular classes of models are briefly contrasted with more general-purpose systems with respect to flexibility, efficiency, and interactive operation. The interactive capability of the language and the communicative function of the monitor emphasize the importance of coordinated design of these elements. To illustrate the principles presented, ceZZ-space modelling and a recently developed interactive ceZZ- space simulation system are discussed.
