Abstract
Abstract The knowledge of an expert user expressing the relationships between phenomena and a conclusion (a rule) is stored prior to the use of the device. Input data are applied to this knowledge in order to make an inference. The possibility of the conclusion is calculated, and the clearness of each phenomenon relative to the possibility of each conclusion is determined by the fuzzy inference device. The phenomena related to a single conclusion which have low static information amount or clearness are selectively eliminated. In this way the rule can be adjusted, the processing time can be reduced, and the reliability of the conclusion can be improved.
