Full title and description

ASME VVUQ 1-2022 — "Verification, Validation, and Uncertainty Quantification Terminology in Computational Modeling and Simulation". A short ASME standard that establishes a harmonized set of terms and definitions used across ASME VVUQ (Verification, Validation and Uncertainty Quantification) standards to improve clarity and consistency in documentation, reporting, and communication about computational models and simulations.

Abstract

This Standard provides a concise, harmonized glossary and explanatory notes for core VVUQ concepts (verification, validation, uncertainty quantification and related terms). It is intended to set common language and themes that connect the VVUQ community and to be used by ASME VVUQ subcommittees so that subsequent, domain-specific VVUQ standards use consistent terminology and definitions.

General information

Scope

Defines and harmonizes terminology used in verification, validation, and uncertainty quantification for computational models and simulations. The Standard clarifies the meaning of terms such as code verification, solution verification, model form uncertainty, epistemic and aleatory uncertainty, validation metrics, context of use, and model credibility. It is intended for use across domains and to serve as a reference for other ASME VVUQ standards and for practitioners reporting VVUQ evidence.

Key topics and requirements

• Harmonized definitions for verification, validation, and uncertainty quantification (VVUQ).
• Clarification of sub-terms: code verification, solution verification, model verification, and model validation.
• Definitions and distinctions for types and sources of uncertainty (epistemic vs. aleatoric; model-form, parameter, numerical, and experimental uncertainties).
• Concepts of context of use and model credibility as the organizing framework for VVUQ evidence.
• Guidance on validation metrics and their relationship to uncertainty quantification.
• Intent for consistent terminology across ASME VVUQ standards and for adaptation by discipline-specific subcommittees.

Typical use and users

Used by engineers, simulation analysts, model developers, validation experimentalists, regulators, standards committees, and researchers who need a consistent vocabulary for describing VVUQ activities and evidence. Typical workplaces include engineering design teams, research laboratories, software vendors, regulatory bodies (for regulated industries such as medical devices and nuclear), and academia.

Related standards

Closely related ASME VVUQ and V&V family documents such as ASME V&V 10 (Computational Solid Mechanics), V&V 20 (Computational Fluid Dynamics and Heat Transfer), V&V 40 (Assessing Credibility for Medical Devices), VVUQ 10.2 (Role of UQ in CSM), and other VVUQ series guides and supplements. It is also complementary to non‑ASME guidance on verification/validation and software/system V&V such as IEEE verification/validation guidance and discipline-specific regulatory guidance.
