Simulation modelling: A comparison of visual interactive and traditional approaches

Visual interactive simulation (VIS) is now an established operational research (OR) technique. While many successful applications of VIS have been reported in the literature, little has been published regarding an appropriate methodology for building a VIS model or of the differences between tackling a problem using VIS as opposed to traditional batch simulation modelling using a simulation language. This article describes the development of a VIS model for a problem where a batch simulation model already existed. An attempt is made to compare VIS modelling with batch simulation modelling with respect to both the modelling process and the resulting model. The usefulness of having an existing simulation model to work from in building in VIS model is also investigated.
