PRODUCTION-RULE FILTRATION MECHANISM AND INFERENCE ENGINE FOR EXPERT SYSTEM INCLUDING SAID MECHANISM

摘要

PURPOSE: To shorten the processing time. CONSTITUTION: In a production rule filtering mechanism 30 which is used for discriminating a single or a plurality of rules the conditions of which are met on a deduced fact in the continuous inference cycle of production rules, a sorting system for ordering the conditions of rules in accordance with a sorting standard is actuated only when the number of facts meeting a certain condition of a certain rule is multiplied or divided by an adjustable coefficient K between the current inference cycle and the inference cycle immediately before the sorting system is started about the rule so that the condition to be met can be expressed and the conditions of the rules can be verified based on the order for taking the conditions of rules into account.
