What is less common is the use of computer graphics to assist the user in setting up simulation models, although for analogue block-orientated systems, the idea is nothing new. This paper concerns a project in which input graphics are applied to a discrete-event simulation language to supplement the conversational-mode input that is already a feature of the package.10.2312/eg.19821019
