CASM—The Right Environment for Simulation

The modeller approaching discrete-event simulation has expected and received a high degree of computer support. The processing power simply to run a model and analyse the results would, of course, be taken for granted, but support has gone far beyond this in promoting the easier and speedier construction of models through specialized program structures, languages and lately program generators. Computer graphics capabilities of mini- and microcomputers have been exploited to secure a readier acceptance of simulation models and results. These support facilities constitute the computer environment within which the fortunate modeller works at present. What more could be expected?The work of an L.S.E. group of researchers is guided by a picture of an ideal environment for simulation modelling. We shall describe this picture and illustrate the progress made towards its implementation. Our principal intention is to promote discussion amongst simulation practitioners about their own ‘ideal’ of a computer support environment and the nature of deficiencies in the current systems.
