<p>A technique in which a cause of an abnormality is presented when the abnormality occurs in a component mounting apparatus is provided. An arithmetic device creates a function of outputting a real value for each cause candidate of the abnormality with inputting the apparatus information by using apparatus information for specifying a frequency at which mounting of a component by a component mounting apparatus fails at least at a time when the abnormality occurs, and cause information for specifying the cause of the abnormality. When the abnormality newly occurs, the arithmetic device outputs the real value for each cause candidate of the abnormality by using a frequency at which mounting of the component by the component mounting apparatus fails at a time when the abnormality newly occurs, and the function, and presents the cause candidate largest in the real value as the cause of the abnormality.</p> |
