Human Error Analysis for System Safety (HEASS)

Course Description

System safety analysis of engineered systems must often deal with the possibility of human error leading to adverse conditions.  Hence, human error probability evaluation is an important part of system safety analysis.  This course presents a summary of the methods and underlying theory for estimating human error probabilities.  The course begins with a discussion on human factors and its influence on human error possibility.  The various methods for estimating human error probabilities under different conditions are presented.  For each method, their background, underlying theory, advantages and disadvantages will be covered.  Typical human error probability values used in various industries will be provided.

Objectives: To familiarize class participants with the human error probability evaluation process.

Who Should Attend: Individuals who intend to enhance their understanding and capabilities in system safety analysis.
