DEVS formalism: a framework for hierarchical model development

Abstract

A methodology is being developed to map hierarchical, modular discrete event models onto distributed simulator architectures. Concept developed for the first step of the methodology concerning model representation are discussed. The DEVS (Discrete Event System Specification) is extended to facilitate modular, hierarchical model specification. Procedures for top-down model development are expressed with the extended formalism and illustrated with a computer system model design.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
