# Decision-Grade Simulation ## Definition A simulation supplies predictions qualified by numerical, physical, and uncertainty assessment appropriate to a decision. The article connects this standard with stockpile stewardship and other consequential systems. ## Regional role Nuclear-stockpile requirements supplied a consequential setting for predictive computation. Verification addresses the implementation, validation compares the model with physical evidence, and uncertainty analysis qualifies the decision. The university research lineage connects national laboratories, UT methods, TACC computation, and experiments without treating a successful method in one domain as automatic validation in another. ## Relationships - **technical or institutional context:** [[wiki/Verification Validation and Uncertainty Quantification|Verification Validation and Uncertainty Quantification]]. - **technical or institutional context:** [[wiki/Predictive Science|Predictive Science]]. - **regional master router:** [[wiki/Austin Defense Technology|Austin Defense Technology]]. - **source article:** [[articles/How Austin Became a Different Kind of Defense Tech Epicenter|How Austin Became a Different Kind of Defense Tech Epicenter]]. - **civilian supplier and participation economy:** [[collections/The Civilian Intelligence Marketplace|The Civilian Intelligence Marketplace]]. - **intelligence architecture:** [[collections/Terrorism, Counterterrorism, and the Intelligence Environment|Terrorism, Counterterrorism, and the Intelligence Environment]]. ## Sources / Provenance - [[articles/How Austin Became a Different Kind of Defense Tech Epicenter#The Executable Loop|Austin defense-tech article — The Executable Loop]] — October 2026 revision; source for this entry’s regional role. - [Bryant McGill, The Austin Executable Loop](https://bryantmcgill.com/research/The+Austin+Executable+Loop) - [U.S. Department of Energy, Timeline of Events: 2008](https://www.energy.gov/lm/timeline-events-2008) ## Connected Austin capabilities [[wiki/Uncertainty Propagation|Uncertainty Propagation]], [[wiki/Nuclear Stockpile Stewardship|Nuclear Stockpile Stewardship]], [[wiki/Verification|Verification]], [[wiki/Verification Validation and Uncertainty Quantification|Verification Validation and Uncertainty Quantification]], [[wiki/Calibrated Simulation|Calibrated Simulation]], [[wiki/Trustworthy Simulation under Consequential Uncertainty|Trustworthy Simulation under Consequential Uncertainty]].
