WISCON. Teilthema: Wissensverarbeitung in dynamischen Prozessumgebungen Abschlussbericht

Abstract

The concept of knowledge-based process supervision and control is aimed at extending conventional process control systems by knowledge-based components. In case of a disturbance, the underlying complex dynamic process shall be brought back to its working regime by means of knowledge-based control measures. Compared to the current state of the art, the implementation of these ideas leads to a proper progress. The Leipzig project group of the joint project WICSON had focussed its investigations and development on five areas: (1) knowledge acquisition, (2) knowledge representation, (3) diagnosis, (4) simulation, and (5) therapy. The results have been partially integrated in the overall research and development project. Particular emphasis has been put on a knowledge-based approach to therapy control and its implementation. Therapy control is understood as an interacting team of modules for: (1) plan generation, (2) plan execution, and (3) constraint monitoring. The approach is based on innovative graph-theoretic concepts for plan generation by context-free graph gewriting and on a refined modal temporal logic for constraint checking and monitoring. There are several implementations ranging from knowledge acquisition and representation via simulation on a cluster of transputers to planning. The underlying languages are C++, Occam, Lisp (CLOS), and Quintus Prolog.
