PURPOSE:To solve a compound problem such as trouble diagnosis including a restoration method and to build a multipurpose, high performance export system by executing the multistaged inference combined with backward inference and forward inference. CONSTITUTION:The titled system is provided with an inference part 1 to execute the forward inference, a backward inference part 2 to verify whether condition used by the forward inference part 1 holds or not, and a rule preservation part 3 to preserve rules in a IF-THEN format. The forward inference part 1 is composed of a presupposition preservation part 11 to preserve presupposition or the inference result just before the presupposition is obtained, a rule search part 12 to search rules that use the presupposition preserved in the presupposition preservation part 11 as one condition in a condition part out of the rule preservation part 3, and a rule execution part 13 to execute the searched rule, and a conclusion decision part 14 to decide whether the conclusion obtained through the execution is goal of inference.
