Filed:

Apr 17, 1989

Appl. No.:

7/339535

Inventors:

David Paradies - Los Osos CA
Edison Tse - Los Altos CA
Gary M. Leo - Fairfax CA

Assignee:

DEL Partners L.P. - Palo Alto CA

International Classification:

G06F 1518

US Classification:

395 61

Abstract:

An expert control system for the real time management of an automated factor is disclosed. Variables within rule base trees of the expert control system are preferably restricted to taking on only four values, namely, true (T), false (F), indeterminate (I), and untested (U). Flexibility for responding to real time changes in the automated factory is provided by a command structure which allows the value of any arbitrary variable within a rule base tree to be changed from its current value to any one of the other three values.

International Classification:

G05F 1500

US Classification:

395 76

Abstract:

Knowledge bases are generated by a computer directly from flowcharts and logic trees. Only a few icons are used in the flowcharts so as to make the flowcharts easier to trace. Different colors are used to indicate the states of statements in the knowledge base. A simulator is provided to simulate knowledge base execution. The simulator displays the corresponding flowcharts and logic trees on the computer screen. The simulator shows which statement is being evaluated and provides various information useful for debugging and personnel training.
