An Introduction to Graph-Based Modeling Systems, Part I: Overview

Abstract
Attributed graphs are a widely used paradigm for representing management science models. Examples include vehicle routing, production planning, simulation and decision trees. With the proliferation of computer graphics, direct manipulation interfaces have been created for many of these models. Although such systems can facilitate modeling and analysis, they generally prove quite expensive to develop. Since all of these models can be represented using an attributed graph, one can exploit that commonality to develop tools and techniques to facilitate developing computer graphics interfaces for such models. This paper discusses the concept of such a graph-based modeling system (GBMS) and a prototype implementation (Networks) that facilitates the creation of computer graphics interfaces for models that can be represented as attributed graphs. This study is divided into two parts; part I presents an overall introduction to the concepts; part II will discuss these concepts in detail.
