Abstract
The multi-fidelity methods assessed by the AVT-331 technical team are described in this chapter. A definition of what constitutes a multi-fidelity method is given, along with a unifying nomenclature. These elements are intended to be as consistent as possible within this chapter and across later chapters to facilitate reading and understanding of the presented results by a broad community. A taxonomy of multi-fidelity methods is proposed whereby nearly 20 multi-fidelity methods studied by the team are categorized into a much smaller set of method classes. The largest class is a set of multi-fidelity surrogate modeling approaches with various online adaptive sampling techniques. Each multi-fidelity method applied by AVT-331 is provided a suitable discussion in this chapter. Not all types of multi-fidelity methods of interest to this group are studied and applied to AVT-331 benchmarks, owing to time and resource constraints. However, a wide range of approaches are evaluated by AVT-331, experience which may be helpful to the NATO vehicle design community.
