The book presents the development of a simulator for approaching human errors in complex operational frameworks (e.g., plant commissioning, Air traffic management etc.). The aim is to integrate the quantification capabilities of the so-called first-generation human reliability assessment (HRA) methods with a cognitive evaluation of the operator. The simulator allows analysing both error prevention and error recovery. It integrates cognitive human error analysis with standard hazard analysis methods (Hazop and event tree) by means of a semi static approach . The comparison between the results...
