The management computer sets a production job having the largest production volume to a production job having the Nth largest production volume of multiple production jobs to reference jobs of N groups respectively (S130), and determines arrangement positions of tape feeders on a pallet so that the production time required for processing the reference job is reduced based on the reference job (S140). In addition, the management computer performs grouping to allocate remaining production jobs excluding the reference job from the multiple production jobs to one of the N groups (S150) and determines arrangement positions of the tape feeders on the pallet based on the remaining production jobs (S160). Since a production job having a large production volume occupies a large proportion of the total production time required for processing the production jobs in the group, the total production time can be reduced by the production job.
