Description
Summary:This paper deals with selected problems of human factors in the design of process control systems. The argument is that although there are already some legal obligations to take human factors into account, practical experience shows that this is not done adequately and sufficiently. Two types of human–machine interfaces are distinguished, i.e. the task interface and the interaction interface. The design philosophy of process engineers seems to aim at automating all safety critical functions, which is called into question based on the available ergonomics evidence. For the interaction interface examples are presented, showing a further substantial neglect of basic human factors principles, which in turn results in increased operator strain during system failures. It is argued that there is a demand for immediate action, i.e. for the application of existing human factors knowledge in process control system design, for a professional evaluation of human factors in process control systems, and for research on possibilities of using new technologies that assist the operator in controlling the process control system.
