ABSTRACT
This chapter considers the application of the human error risk management for engineering systems methodology for safety assessment studies. The application concerns the recurrent safety audits of a large organisation in the domain of railway transportation systems. A number of standpoints should be considered when studying a Human machine system (HMS), such as, definition of the goals of the HMS under study and/or development, concept and scope of the HMS under study and/or development, type of analysis to be performed, area of application, and indicators of safety level. Human error risk management for engineering systems must be supported by existing models and specific methods for performing each step of the procedure. A Human error risk management for engineering systems application requires considerable effort from the human factors specialists, for the collection of the relevant information and data. Technique for Human Error Rate Prediction is normally utilised in human reliability assessment to calculate probabilities of human errors associated with the performance of tasks.
