Abstract

 

 The research model presented in this article, of control room operators’ work activities in an electric power system, includes an analysis of the main control room’s characteristics, the performance of the operators, and the influence of the environment on the operators’ efficiency. For the purpose of group ranking the most important aspects describing the risk factors, fuzzy numbers are used. The influence of all the experts on the final decision is based on their previous experience. Human system, control information system, and supporting system elements are used as assessment criteria. In the analysed control room, the major impact on the operators’ efficiency is the causes and effects of stress and the presentation of information. Display panels and control desks are crucial aspects of the control information system, as they affect the efficient presentation of information. In relation to the indoor environment, lighting conditions are identified as the most important. Based on the results obtained, we propose changes that decrease the risks by enabling better work positions for operators and the presentation of information on display panels and graphic screens.
