MANUFACTURING HUMAN MACHINE INTERFACE DESIGN USING PLANT MODELS

The challenge today to improve SCADA (Supervisory Control And Data Acquisition) systems is to integrate concepts coming from cognitive science and results from automatic control. Ecological Interface Design proposes an original design methodology to facilitate human operator perception. In this paper, we propose an approach to apply such methodology on manufacturing Discrete Event System design. The methodology is based on plant modelling. This design methodology of plant model is closed to material structure of the plant and associates real time plant evolutions to meaning full information. The methodology is illustrated with an industrial example that shows advantages compared to a “classical” supervisory HMI based on controller inputs/outputs.
