PROBLEM TO BE SOLVED: To perform, regardless of replacement time, leveling on work of replacing an accommodation unit in use with a spare accommodation unit accommodating parts.SOLUTION: A management computer 60 sets the number of residual parts of a specific feeder 72 as the number of replacement time parts, which is the number of parts used for notifying a worker of replacement with a spare feeder 76, by using the total number of parts included in the specific feeder 72 and a predetermined change value differing from that of another feeder 72; and outputs replacement information on the set number of replacement time parts to a mounting apparatus 11. After that, the mounting apparatus 11 notifies a worker of notification information showing that the feeder 72 in use is to be replaced with the spare feeder 76, when the number of residual parts of the feeder 72 has reached the number of replacement time parts in the replacement information. Thereby, the numbers of replacement time parts used for replacement with spare feeders 76 by respective feeders 72 are different. Replacement time of a spare feeder 76 to be used for replacement in a certain work period is made to be hardly overlapped with replacement time of another spare feeder 76. |
