置。 In a fault diagnosis device that diagnoses a fault using data representing the cause-and-effect relationship between a fault cause and an observed event in a matrix, the dependent relationship between observed events is registered as data, and when the observed event is observed or an operator When input, the dependent relationship is searched, and when the establishment/non-establishment of the observed event or related observed event is clear from other observed events, it is determined that it will not be used for fault diagnosis, and the probability of the cause calculated by diagnosis is determined. The larger the observed event and the stronger the causal relationship with its cause, the higher the priority is given to questions to the operator or automatically entered, and when it is determined from the above judgment that it will not be used for fault diagnosis, if the observed event has already been observed, it will be ignored. A fault diagnosis device characterized in that it is configured to diagnose a fault and, if it has not been observed, lower the priority of questions or automatic input, or not to ask or input.
