Production systems for process control: Advances and experiences

Abstract Production systems are still regarded as one of the most important paradigms for solving complex tasks. However, in embedded control systems production systems have not yet been applied intensively. We identify open issues for production systems in process control by exemplary presenting two industrial fielded expert systems. We describe how these expert systems have been applied to process control, discuss lessons learned, and show how practical experience has influenced our own research activities. Finally we identify future research directions of general importance.
