Breadth-depth triangulation for validation of modeling and simulation of complex systems

Abstract

We give an approach for supporting validation for complex modeling and simulation. We present a means of characterizing methods, Breadth-Depth, which encompasses techniques ranging from simulation to unstructured human judgment. Based on this framework, we argue that a cost-effective method V&V of complex simulations is triangulation of simulation against breadth methods. We propose a specific instantiation of this approach, based on morphological analysis (MA). We describe a software tool to support MA-based breadth-depth triangulation.
