3MRA UNCERTAINTY AND SENSITIVITY ANALYSIS
Citation:
BABENDREIER, J. E. 3MRA UNCERTAINTY AND SENSITIVITY ANALYSIS. Presented at Science Advisory Board Review, Washington, DC, August 26 - 27, 2003.
Impact/Purpose:
The primary goals are to: (1) Construct a 400-node PC-based supercomputing cluster supporting Windows and Linux computer operating systems (i.e. SuperMUSE: Supercomputer for Model Uncertainty and Sensitivity Evaluation); (2) Develop platform-independent system software for the management of SuperMUSE and parallelization of EPA models and modeling systems for implementation on SuperMUSE (and other PC-based clusters); (3) Conduct uncertainty and sensitivity analyses of the 3MRA modeling system; (4) Develop advanced algorithmic software for advanced statistical sampling methods, and screening, localized, and global sensitivity analyses; and (5) Provide customer-oriented model applications for probabilistic risk assessment supporting quality assurance in multimedia decision-making.
Description:
This presentation discusses the Multimedia, Multipathway, Multireceptor Risk Assessment (3MRA) modeling system. The outline of the presentation is: modeling system overview - 3MRA versions; 3MRA version 1.0; national-scale assessment dimensionality; SuperMUSE: windows-based supercomputer; 3MRA ver1.x - UA/SA software tools; model evaluation approaches; 3MRA version 1.0 UA/SA plan; and example model output using version 1.x.
