e-PSM 216: Quantitative Risk Analysis

DURATION: 3 Days, 9AM-4PM

COURSE DESCRIPTION
This training course provides in depth knowledge on how to perform and understand a quantitative risk assessment with the help of Worked Examples. In this course the participant will learn about the key components of a QRA, the expected outcomes, and how to effectively perform and audit QRA studies.  The course will also cover Industry best practices and lessons learned.  Upon successful conclusion of the training course, participants should be prepared with the tools and skills to efficiently and effectively perform and evaluate a QRA.
