A combination of batch exchange carts 18 that includes all of the feeders 17 that supply components to be used in the post-changeover production from the multiple batch exchange units 18 prepared in preparation space 25 is decided based on the component information of feeders 17 loaded on batch exchange carts 18 used in the pre-changeover production and setup information of batch exchange carts 18 that can be used for exchange memorized in memory device 23 (component information of feeders 17 loaded on batch exchange carts 18 in preparation space 25), and then an operator is notified of the decided combination of batch exchange carts 18 by sound or by the display of a mobile terminal or display device 24 of production management computer 21. Here, in a case in which there are multiple combinations of batch exchange units 18 that include all of the feeders 17 to be used in the post-changeover production, the production cycle time may be calculated for each of the combinations, and an optimal combination that is the combination with the shortest cycle time may be decided and notified to an operator via sound or display.
