    Patent number: 5208898
    Abstract: A knowledge processing system in which a grade representing a degree at which an event is satisfied or unsatisfied is obtained depending on a condition part represented in a form of a logical arithmetic expression including an expression of a fuzzy logic and on a grade of satisfaction of the condition part generates rules on assumption of unmeasurable events associated with states of the external field of the system so as to add the rules to the rules related to the unmeasurable events. Forecast of a value of a measurable event is more correctly achieved depending on grades of satisfaction of the unmeasurable events and grades of satisfaction of measurable events. A warning may also be issued according to the forecasted value.
