FAILURE CAUSE IDENTIFYING PROGRAM, FAILURE CAUSE IDENTIFYING APPARATUS, AND FAILURE CAUSE IDENTIFYING METHOD

摘要

A failure cause identifying program that causes a computer to execute a process, the process includes extracting a first node related to a node indicating abnormality included in a plurality of nodes; identifying a first objective variable and a first explanatory variable of the first objective variable, the first objective variable being each of combinations of operation data of the first node and the first node; extracting, in a detection process performed by using the first explanatory variable, a second objective variable and a second explanatory variable of the second objective variable, the second objective variable being each of combinations of the operation data and the node indicating abnormality; determining a number of objective variables common to the second explanatory variable; and setting a priority order for locations of a cause of a failure, based on the number of objective variables.
