Abstract

Reviews of previous work on visual interactive simulation, and on the interface between humans and computers were undertaken, the latter considering the physical and psychological aspects of the subject.
Two simulation projects carried out in association with Rolls-Royce Aero Engines and the British Steel Corporation are described in detail.

As a result of these projects and the review of previous studies, a major weakness in the technology of visual interactive simulation was identified: while the visual representation aids validation, verification, and experimentation, no facilities are provided to assist the analyst in the task of model construction. Simulation program generators are of proven use for non-interactive models, but a visual model requires a graphically oriented approach.

The main section describes the design and implementation of a substantial extension to the simulation software developed at Warwick. This allows the design and development of displays to be carried out 'on-line', while preserving the one-to-one correspondence between simulation entities and their visual representation. It is suggested that this has the potential to significantly reduce the elapsed time taken to develop visual simulation models, while increasing the involvement of the user (or sponsor) in the modelling process, especially when 'pre-defined' entity types are used to minimise the amount of model- specific coding required.

Finally, potential routes for the further development of visual interactive simulation are discussed, including the implementation of a 'simulation language' interpreter within the existing software. This would result in a system which was fully interactive, easing model development as well as experimentation.
