Modelo conceitual de cenários de acidentes causados pelo erro humano em sistemas industriais críticos com foco na concepção de interfaces ergonômicas.

Abstract

This work is centred in the process of building a conceptual model of accident scenarios caused by the human error, and focuses on the conception of ergonomic interfaces. The conceived process was validated through a case study in the context of the electric sector, with a corpus extracted from an electricity distribution and transmission company. The model building essentially consists of knowledge extraction from company’s reports on accidents. In this particular case, the chosen corpus consists of a set of accidents that initiated by the human error during the interaction between operators and the supervision and control system in substations. As a result of the modelling process resulted: an ontology of the analyzed context, a categorization of the human error and an accident typology. The resulting model will allow the integration of the accidents situations knowledge in the process of human interface conception, for the studied context, whereas the case study specific model, will support the construction of an accident simulator for the company. This work fits into the research context of the human interface group GIHM - UFCG, whose main research subject is the extension of the Method for Conception of Ergonomic Interfaces - MCIE, in order to adjust it for the critical industrial systems context.
