An object is to determine optimal board stopping positions while achieving both the avoidance of interference between two mounting heads and shortening of moving time in an electronic component mounting machine. There are provided a movement time calculation step (step S102) of calculating respective movement times in which first and second mounting heads move respectively in order to mount electronic components when a first printed circuit board is positioned in one set position of a first side and a second printed circuit board is positioned in one set position of a second side, an interference loss time calculation step (step S104) of calculating a waiting time which is a time in which, while one of the first and second mounting heads enters an interference area, the other waits to enter the interference area as an interference loss time based on a probability that, when one of the first and second mounting heads is anticipated to enter the interference area, the other is moving within the interference area, and based on a movement time in the interference area in which there is a likelihood that the first and second mounting heads which correspond to the respective first and second printed circuit boards which are each positioned in the same set positions as in the movement time calculation step will interfere with each other, and a stopping position determination step (step S106) of determining the first side set position and the second side set position which are selected from among all combinations as board stopping positions based on total movement times which are calculated for all of the combinations of the first side set position and the second side set position by the movement time calculation step and the interference loss time which is calculated by the interference loss time calculation step. |
