NASA’s Seventh Workshop for
Probabilistic Risk Assessment Methods
(PRAM-7)
 
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).
