Overview:
This four-day workshop will cover the applicability of Probabilistic Risk Assessment (PRA) to NASA programs/projects and activities, the current state-of-the-art of PRA methodology for aerospace applications, and its use in risk-informed decision-making. The workshop will be valuable to both program/project managers and PRA practitioners. It will begin with an introduction to PRA for managers, including its role in risk-informed decision-making. Following this introduction, there will be a discussion of the major concepts used in PRA. Several recently completed studies that have used PRA techniques to support decision-making will be presented. Additionally, the new NASA handbook entitled “Bayesian Inference for NASA Risk and Reliability Analysis” will be introduced.
Topics to be covered are:
PRA Overview and its Role in Decision-Making
The Concept of Probability and its Application in PRA
Logic-based Modeling Techniques and their Application to PRA
Simulation-based Modeling Techniques and their Application to PRA
PRA of a Preliminary Design Concept
Event Probabilities and Hardware Failure Models
Modeling of Uncertainties and Data Analysis
Modeling and Quantification of Dependent Failures
Human Reliability Analysis
Importance Measures and Risk Ranking and Their Applications
Uncertainty Propagation
Bayesian Inference Techniques
PRA Modeling Process
Physical and Phenomenological Models
Software Failure Modeling
Precursor Analysis
Objectives:
At the end of this course, participants will understand the fundamentals of PRA and its potential role in decision-making. This understanding is essential to meet the requirements of NPR 8705.5, Probabilistic Risk Assessment Procedures for NASA Programs and Projects; NPR 8715.3, NASA General Safety Program Requirements (System Safety Requirements); and NPR 8000.4, Integrated Agency Risk Management Procedural Requirement (draft revision).
