3 Methodology

Our methodology assumes that a simulation exists and is suspected to be correct. We propose a five-step approach for exploring the simulation for unexpected behaviors as shown in Fig. 1. Step 1 requires creating hypotheses, specifications, and boundary conditions for establishing baselines for determining if outcomes appear unexpected. Step 2 involves identifying outputs of interest; i.e. the outputs required to check the hypotheses, specifications, and boundary conditions identified in Step 1. Step 3 involves running the simulation. Step 4 involves collecting the outputs of interest identified in Step 2 from the simulation runs. Step 5 involves creating visual representations of the outputs of interest in order to provide a means for exploring the outcomes. These visualizations are compared against the V&V hypotheses, specifications, and boundary conditions from Step 1 to identify any suspicious behaviors. We use visualization techniques in the form of spatial plots and heat maps to conduct V&V on the simulation.
