Abstract

PURPOSE:To execute a processing close to the judge of a human being of a simple system constitution at a high speed by equipping a central processing circuit, knowledge-based memory and a frame retrieving circuit, etc., and using the two types of the knowledge based whose construction methods are different. CONSTITUTION:By setting two types 1 and 2 in which a condition and a cause go to be bidirectional as the form of the knowledge base, respective processes of intuition, experience, theory and squeezing are included as an estimating method. A diagnosis procedure is to go through steps to pursue a cause system by repeating condition cause(=condition) cause in the same way as the thought and judge of the human being. The judged value is included as the element of the knowledge base and a study is made easy by adjustment and confirmation with a simulation. Thus, by the hardware of a small size, which is only composed of a microcomputer 8 and simple exclusively used circuits 1-7, the total estimating process and the diagnosis procedure, which are miniaturized and resemble to the thought of the human being, can be completely executed at a high speed.
