Title: Quantification of Uncertainties in Integrated Spacecraft System Models
Agency: NASA
Contract: NNX10CF64P
Award Amount: $99,996.00


The proposed effort is to investigate a novel uncertainty quantification (UQ) approach based on non-intrusive polynomial chaos (NIPC) for computationally efficient and accurate quantification of uncertainties in spacecraft system models within a multidisciplinary analysis and optimization (MAO) framework. The UQ approach will include the modeling of both inherent (probabilistic) and epistemic uncertainties and the propagation of these with NIPC. Comparisons between crude Monte-Carlo sampling will be made during validation of the approach. Software will be developed to implement the UQ approach in a generic way. With scalability in mind, this software will be utilized within a space system MAO framework containing many uncertain parameters. Also in Phase I, a simple graphical user interface will be created to implement the UQ approach. Both the software and UQ approach developed will be tested on a model spacecraft simulation problem with uncertainties. This proposed work will compliment M4 Engineering's expertise in developing modeling and simulation technologies that solve relevant demonstration applications. The researchers from Missouri S&T (RI) will guide the implementation of UQ methodology and contribute to the proposed effort with their experience and expertise in UQ in aerospace simulations.
