GRAPHICAL DESCRIPTION AND A PROGRAM GENERATOR FOR QUEUING MODELS

The Queuing Model Generator (QMG), described in this article, is a module of the environment of the simulation language PASION. It contains a block-diagram editor which permits the user to define the structure of the model, and a program generator which generates the corresponding PASION code. This code is automatically translated to PASCAL. QMG is transparent, (i.e. the languages PASION and PASCAL are not visible for 'non-programmer' users.) However, if the user knows PASION or PASCAL, then he can work with the resulting code, creating more complex models. An application in flexible manufacturing systems design is described.
