Análise de usabilidade nas consoles de operação de uma unidade de destilação de petróleo instalada em Manaus

Abstract

The man-machine interfaces are an important element of control processing units of oil. It is through them that the operating personnel keeps the process variables within the limits of safety and quality. Usability measures the ease with which an interface can be manipulated and the satisfaction in their use among other attributes. This study aims to evaluate the operating screens s usability attributes for a distillation unit of an oil refinery by measuring interface user s performance and subjective satisfaction in it s use. The evaluation of current system s usability level was accomplished through the application of standardized forms in operating personnel, engineering and maintenance involved in developing and operating the system in addition to measuring performance in the tasks execution. The survey identified the groups most affected by the current configuration of the interface and showed that the attributes of memorization and use efficiency were those with greater potential for improvement. Also as a result of this work, was identified some points that can be improved to increase performance in use and can increase the satisfaction of its users. Keywords: Usability, Security, Performance.
