System-Level Validation through Post-Flight Reconstruction and Anchoring
Abstract
Describe the approach of using System Level Post-Flight Reconstruction (SPFR) as a Model and Simulation (M&S) Validation method for the Missile Defense Agency. Three interrelated but distinct processes that gather and evaluate evidence to determine, based on the simulation's intended use, the simulation's capabilities, limitations, and performance relative to the real-world objects it simulates are: - Verification: - Process of determining that a model implementation and its associated data accurately represent the developer's conceptual description and specifications - Validation: - Process of determining the degree to which a model and its associated data are an accurate representation of the real-world from the perspective of the intended uses of the model - Techniques are not limited to comparison of simulation results with test data. Among the other techniques employed are data validation, sensitivity analyses to evaluate input/output relationships, comparison with other models and simulations known (or assumed) to have validity in the operating range required (benchmarking), and the results of SME reviews of M&S outputs (face validation) One method of validation is anchoring - Accreditation: - The official certification that a model, simulation, or federation of models and simulations and its associated data are acceptable for use for a specific purpose.
