PURPOSE:To simplify the correction of a rule and to compile it to the set of the rule of a high quality by comparing and studying the difference quantity of a value of a result obtained by applying the rule to input information and its expected value and reducing the concept of the rule when it is necessary to correct the rule. CONSTITUTION:When information is inputted from an input device 7, a rule described in a 'condition part - execution part' format is applied to this input information and a controlled variable is derived by an inferring part 1. A correction deciding part 2 brings the controlled variable derived by the inferring part 1 and the expected value of a controlled variable when the rule is applied to the input information, to comparing operation, retrieves the rule to which the input information conforms, based on an error to the expected value of the controlled variable and obtains the rule to be corrected. As for this rule to be corrected, its concept is reduced and corrected by a correction rule generating apt 3, and this rule is rearranged in order from the rule scarcely having an unfavorable influence which follows up the correction by referring to a history data file by a correction rule selecting part 4 and outputted from an output device 8. In such a way, the rule can be compiled simply. |
