Human centered modeling of incident scenarios

This paper presents the process employed in obtaining a conceptual model of human errors scenarios for the electrical power industry. The process is based on the analysis of the industry's reports on human and operational errors using the knowledge acquisition method KOD [C. Vogel, 1988]. This paper also presents the resulting incident scenario model and discusses how it is validated. This model is used to build a process control simulator with which it is possible to study the user behavior when dealing with safety critical situations. A cognitive model of the user behavior when working under critical situations is extracted from these models, to be incorporated into a method for the conception of user interfaces
