Summary | The Navy uses families of models of varying detail to analyze forces and operational concepts. The information gleaned in these model-supported studies helps shape what the future Navy will look like and how it will fight. The current practice in the higher-to-lower-fidelity sequence of modeling is to use point estimates of more focused higher-fidelity model outputs as the inputs for the broader lower-fidelity models. It is vitally important to understand how these lower-level model errors are propagated through the series of models and how the decisions are effected as a result. This research will review previous efforts related to propagating errors in hierarchical models, explore the effects of multiple approaches, and provide recommendations on extending and applying the methods-which will include uncertainty analysis, design of experiments, and meta-models. The research will be guided by application to the Anti-Submarine Warfare (ASW) mission area. |
