Visualization and simulation with the object oriented programming system Smalltalk-80H

An essential problem in implementing simulation techniques is the accuracy of the model. With the help of visualization techniques, a complex simulation model from the area of chemical production can be represented. This model can be controlled and altered interactively. Simulation and visualization can be described within object-orientated systems in a very natural way. Simulation and visualization have been implemented with the help of the Smalltalk-80-system and the Hypermedia-System with the name ‘The Analyst’ written in Smalltalk-80. This is used in the field of operations research at the Ciba-Geigy AG, Basel.
