Operators need to be able to act promptly on changing situations requiring remote actions to process plants. A formal development process is proposed to determine the minimum amount of information that needs to be presented at interfaces. The first stage...
This paper deals with a hierarchical and modular structure for real time control and monitoring of large discrete event systems. The first aspect of these works concerns the complexity of the physical process to be controlled: the whole process is split up into more simple subproblems. This splitting up procedure is recursive and stops when the resulting subprocesses are simple enough to be solved...
