AFFECTION RANGE IDENTIFICATION PROGRAM, AFFECTION RANGE IDENTIFICATION METHOD, AND AFFECTION RANGE IDENTIFICATION DEVICE

摘要

To determine the difference of the level of possibility affected by a fault.SOLUTION: An affection range identification device 10 acquires fault occurrence information 3 indicating a first apparatus in which a fault occurs. Next, the affection range identification device 10 searches for a plurality of second apparatuses present within a first affection range 4 which has possibility affected by the fault, where the first apparatus is a starting point. Next, the affection range identification device 10 determines whether or not abnormality has occurred for each of the plurality of second apparatuses. Next, the affection range identification device 10 determines whether or not a third apparatus is present within second affection ranges 6a, 6b and 6c which have possibility affected by the fault, where the third apparatus in which the fault occurs is the starting point. Next, the affection range identification device 10 determines rank for each of the plurality of second apparatuses on the basis of a determination result concerning whether or not the third apparatus is present within the second affection ranges 6a, 6b and 6c. In addition, the affection range identification device 10 outputs rank information 7 which indicates the determined rank.SELECTED DRAWING: Figure 1
