PROBLEM TO BE SOLVED: To confirm how effective each component used for data processing has done. A tool execution unit 210 executes each of one or more parts used for data processing. The execution information acquisition unit 220 includes a number of machining operations, which is the number of machining processes executed by each of the one or more parts, and a discriminant number, which is the number of discrimination processes executed by each of the one or more components. To get. The service amount calculation unit 230 calculates the service amount of each of the one or more parts by using the processed number of each of the one or more parts and the discriminated number of each of the one or more parts. The service amount visualization unit 240 displays the service amount of each of the one or more parts on the display. [Selection diagram] Fig. 1
