Software Library for Explicit Uncertainty Modeling - Prototype Development Report
Abstract
An approach for automated uncertainty propagation through deterministic models is developed. The mathematical basis for uncertainty propagation based upon error analysis is derived. a modular, reusable, and universally applicable method of implementing the approach to software is presented, with examples in both Formula Translator (FORTRAN)-90 and C++. Verification techniques are developed and tested. The utility of the approach is demonstrated with an example uncertainty analysis. The example model was taken from the chemical and biological warfare hazard prediction simulation, Vapor, Liquid, and Solid Tracking (VLSTRACK). the methods for extending the approach with additional capability are outlined. The modules presented are applicable to many engineering simulations where uncertainty characterization is desired. Furthermore, the modules can be incorporated into existing codes without redevelopment. Applications include sensitivity analysis, systems architecture studies, and research investment planning.
