The purpose of this paper is to present a new conceptual framework for visual simulation modeling, the multifaceD coOnceptual fraMework for vIsual simulatioN mOdeling (DOMINO). The DOMINO provides both design and implementation guidance to furnish a broad range of support during the model development life cycle; enables the modeler to work under the object-oriented paradigm; guides the modeler in graphically structuring a visual simulation model at multiple levels of abstraction; enables the extraction of sufficient information from the modeler so that the model execution can be visualized; embodies a WYSIWYR (What You See Is What You Represent) philosophy and enables the modeler to represent a system as it is naturally perceived; among many other features
