The group determination unit 170 adds one dimension representing the difference in certainty to the number of dimensions representing the work area 330, and calculates the similarity between the two tasks using the multidimensional distance. Further, the storage device 140 stores a similarity table showing the similarity between two different work types 340, and the group determination unit 170 uses the similarity table of the work type 340 by using the similarity table stored in the storage device 140.
