<p><P>PROBLEM TO BE SOLVED: To provide a failure analysis support device capable of efficient analysis of causes for a failure. <P>SOLUTION: In extracting a failure part, a range of the degree of abruptness one desires to extract is first designated (S21). As a method for designating the range, something abnormal more than a threshold value or not abnormal is designated. Ranges are divided in advance and a selection may be made out of them. Then, within the designated range, a pareto chart is created (S22). On the basis of the created pareto chart, a failure is extracted (S23) and its causes are analyzed (S24). <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
