FAILURE CLASSIFYING DEVICE, FAILURE CLASSIFYING METHOD, AND FAILURE CLASSIFYING PROGRAM

Provided are a failure classifying device, a failure classifying method, and a failure classifying program capable of specifying the causes of failures even when a controller does not generate an alarm. A failure classifying device includes: a failure unit acquiring unit that acquires a data set in which a failure unit of a machine is correlated with one or a plurality of constituent parts; a failure history acquiring unit that acquires a failure history including events of failures that occurred in the past and countermeasure parts; and a correlating unit that stores information on one or a plurality of events in correlation with the failure unit by matching the constituent part to the countermeasure part. 本发明提供即使在控制装置没有产生警报的情况下也能够确定故障的主要原因的故障分类装置、故障分类方法以及故障分类程序。故障分类装置(1)具备：故障单位取得部(12)，其取得将机器的故障单位与一个或多个结构部件对应起来的数据集；故障履历取得部(11)，其取得包括过去发生的故障的现象以及对策部件的故障履历；以及关联部(13)，其通过将结构部件与对策部件进行匹配，将1个或多个现象的信息与故障单位关联起来进行存储。
