Abstract

To generate a problem solving plan and/or a system control plan respectively in association with the contents of the problem and/or the system operation conditions, there are disposed element knowledge for storing therein problem solving methods and system control guidelines and harmonizing knowledge for selecting and/or modifying the element knowledge. Depending on the contents of the problem and/or the system operation conditions, selections and modifications are executed on the problem solving methods and system control guidelines so as to produce an optimal problem solving method and/or an optimal system control guideline. Even when the solving method, the problem solving condition, and system executing situation vary depending on a given problem solving condition and a given system executing situation, an appropriate solving plan can be proposed.
