A Systems Methodology for Structuring Framilies of Models at Multiple Levels of Resolution

This paper presents a methodology for structuring families of models expressed at multiple levels of resolution and integrating them into a coherent whole. The importance of such structuring for model reusability and interoperability has been well discussed by Davis [5]. Thismultiresolution methodology was demonstrated in a prototype application to a family of models from the US Army CECOM library. The approach is based on a research in modelling and simulation methodology that has been in process since the early 70's and which has produced a framework and supporting software environment to manage the complexity of large system modelling and simulation. In what follows, we shall rst review the basic framework and concepts underlying formal approaches to multiresolution model construction. This is followed by a discussion of the application and conclusions that are drawn from it.
