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
