Towards an intelligent editor of industrial control views, using rules for ergonomic design
Résumé
Many ergonomic problems must be taken into account while designing control and supervision views proposed to the operators in control rooms of automated production systems. Tools for solving these problems are proposed in this paper. The first one is SYNOP, an expert system for the static ergonomic evaluation of industrial control views. In its knowledge bases, this system uses ergonomic concepts of graphic information presentation, implemented with production rules.
The second tool is a module for assisting the design of supervision views. Its principle consists in building one or several synthetic overall views, starting with different subviews of related subsystems, and according to the abstraction levels. Indeed, operator evaluates the process at different abstraction levels according to the problem to be solved and uses knowledges corresponding to these levels for problem solving.
Finally, the evolution of SYNOP towards an “intelligent” editor of industrial control views is presented in the last part of the paper.
