Probabilistic and Uncertainty Quantification Methods for Model Verification & Validation (Virtual Classroom)

Uncertainty quantification (UQ) methods are essential for designers, engineers, and scientists to make precise statements, as well as quantify numerically, the degree of confidence they have in their simulation-based decisions.

Quantifying the total uncertainty in a simulation will ensure decision-makers can measure the credibility of a prediction and proactively work to save time, allocate resources, and reduce the risk of inadequate safety, reliability, or performance of the system. Everyone has a model but it is challenging to communicate the approximations, assumptions, and uncertainties that exist in any model prediction. Utilizing a UQ framework will provide you with a consistent and proven way of using the uncertainty in model predictions to make risk informed decisions. 

This course explains the concepts and effective procedures used not only to predict uncertainties in a model, but to also mature your model and build trust in your organization by being able to communicate and document your findings. This systematic framework focuses on methods, approaches, and strategies for quantifying uncertainties in model predictions.

Apply what you learn! Probabilistic and UQ methods are presented in-depth followed by exercises to reinforce the material. Attendees will learn how to use the NESSUS probabilistic analysis software and will apply it throughout the course to gain experience in problem formulation and results interpretation and communication. 

By participating in this course, you will learn how to successfully:

• Identify potential uncertainties in models and data.
• Represent uncertainties in models and inputs.
• Explain how uncertainties impact model predictions.
• Select methods to efficiently propagate uncertainties in the models.
• Identify options to reduce uncertainties in the model predictions.
