本标准旨在扩展不确定度量化（UQ）在验证、确认和不确定度定量（VVUQ）中的重要作用，如图1.1-1所示。UQ在图中所示的“建模与仿真”和“物理实验”分支中发挥着重要作用，最终量化了生成“模拟输出”和“实验输出”的“模拟结果”和“试验结果”中的不确定性。ASME V&V 10-2019中提供了该图的详细描述。 与ASME V&V 10-2019的目的一致，开发ASME VVUQ 10.2的动机是需要计算实体力学（CSM）中的通用UQ语言和过程，特别是因为它可能与模型开发人员如何执行UQ以及他们随后如何传达结果、结论和决策建议有关- 制造商决策者可以是任何个人或代表机构，如审查小组，负责确定模型是否可用于其预期用途。决策者也可以是依靠模型预测来告知决策的客户。

The purpose of this Standard is to expand upon the important role of uncertainty quantification (UQ) in verification, validation, and uncertainty quantification (VVUQ), as outlined in Figure 1.1-1. UQ plays an important part in each of the "Modeling and Simulation" and "Physical Experimentation" branches illustrated in the figure, ultimately quantifying the uncertainties in the "Simulation Results" and "Experimental Results" generating the "Simulation Outputs" and "Experimental Outputs." A detailed description of this figure is provided in ASME V&V 10-2019. Consistent with the purpose of ASME V&V 10-2019, the motivation for developing ASME VVUQ 10.2 is the need for a common language and process of UQ in computational solid mechanics (CSM), particularly as it may relate to how model developers perform UQ as well as how they subsequently communicate results, conclusions, and recommendations to a decision-maker. A decision-maker may be any individual or representative body, such as a review panel, deemed responsible for determining if a model is acceptable for its intended uses. The decision-maker may also be a customer relying on model predictions to inform a decision.
