PROBLEM TO BE SOLVED: To improve examination efficiency by detecting a failure having the same causing spot by a method other than retrieval by a key word.SOLUTION: In a failure information management device, a route of trouble propagation (referred to as the route) along a call relation between a phenomenon module and a cause module, the number of passing times through each module of the route ([module call frequency]), and the number of passing times through each call relation ([call frequency between modules]) are managed relative to each failure generated in the past, and a cause module is retrieved from a phenomenon module of a trouble phenomenon generated newly, based on the information. |
