What Alumni Are Saying . . .

"Very good course - an excellent overview of the concerns and assumptions underlying this technique. Dr. Swain added real value. There's nothing better than getting the perspective of the master of the technique." - Jerry Bueck, Safety Analyst, Los Alamos National Laboratory

Course Description

In this course, you will learn qualitative and quantitative methods for assessing the ways human performance affects the reliability of complex systems. Upon completion, you will be able to perform a human reliability analysis (HRA), which is a necessary part of any complete probabilistic risk assessment.

First, you will learn to qualitatively identify errors, a valuable input to designing or improving systems for high reliability. You will then learn HRA procedures to assess the quantitative influence of human errors on system safety and productivity.

Essential analysis tools you will cover:

  • Performance shaping factors (PSFs)

  • Evaluation of written procedures

  • Human-machine system analysis

  • HRA event trees

  • Human performance data and models

  • Human error probability estimation

The course materials include:

  • Handbook of Human Reliability Analysis (NUREG/CR-1278, August 1983)

  • A Procedure for Conducting a Human Reliability Analysis (NUREG/CR-2254, May 1983)

  • Accident Sequence Evaluation Program (ASEP) Human Reliability Analysis Procedure (NUREG/CR-4772, October 1986)

  • A Manager's Guide to Reducing Human Errors (ACC, July 1990)

Also included is a 300-page handout, which is a compilation of (1) data tables from the Handbook, (2) descriptive information not found in the Handbook, and (3) new data and models from the ASEP Procedure. The handout material stands alone; you can use it to perform HRAs of any complex human-machine system.

You should attend this course if you are a:

  • Manager

  • Engineer

  • Technician

  • Analyst

concerned with improving human reliability in system design, plant operations, and plant safety. Analysts interested in assessing the quantitative impact of human errors on the reliability of complex systems should also attend.

Anyone interested in examining the risk posed by engineered systems will benefit from the course because the principles and techniques taught in the course apply to any type of complex engineered system. (Attendees should bring a scientific calculator to the course.)

Five reasons for you to attend:

  1. Your workers keep making mistakes, even though you tell them to be careful

  2. The course instructors developed the Technique for Human Error Rate Prediction (THERP) and have applied it to many practical situations in both the process and nuclear industries

  3. Human error dominates the probability of engineered system failures; you will learn what you need to know about HRA in this course

  4. You need to estimate the likelihood of human errors leading to defined accident scenarios

  5. You want a quick screening method to identify human errors that should be evaluated more thoroughly

Five benefits you will gain:

  1. You will be able to identify effective (often inexpensive) ways to improve worker performance

  2. You will be able to write more effective procedures based on a thorough task analysis

  3. You will be able to estimate the likelihood and importance of human errors that can lead to system failures

  4. You will be able to perform a detailed human reliability analysis

  5. Come away from the course with these valuable materials:

    • A copy of the comprehensive course notes

    • Solutions to the example problems

    • The extensive course materials listed in the course description

    • A certificate of completion

    • 3.1 CEUs, 3.1 COCs, 4.0 CMs (ABIH approval #02-964)
