Model Verification and Validation

Abstract

With respect to the permanent increasing importance and complexity of modeling and simulation applied for the analysis, synthesis and for training of (technical) systems, model verification, validation and accreditation (VV&A) becomes a more and more important issue.

At the begin, this presentation will summarize major demands and challenges for effective and efficient VV&A. Based on these requirements, we will present a methodological concept for introducing VV&A as part of the model development and life cycle process along which each modeling phase produces a specific intermediate result (such as a structured problem description, a conceptual model description, a formalised model description, an executable model or experimental data). Specific techniques are applied for verification and validation of these well-structured intermediate results.

This conceptual approach results from several research projects on discrete event simulation in which we have been involved over the past years. We will also present an implementation plan of the proposed VV&A concept and will conclude with an outlook towards the planned concrete prototypical realization and its application.
