Space Filling Designs for Modeling & Simulation Validation

System evaluations increasingly rely on modeling and simulation (M&S) to supplement live testing. Thus, it is crucial to thoroughly validate these M&S tools using rigorous data collection and analysis strategies. Space filling designs (SFD) are often the most effective and efficient way to collect data from the model and support a complete evaluation of the model’s behavior. This paper is a survey of the SFD literature with the narrative specifically geared towards M&S validation and some of the unique challenges encountered in test and evaluation.
