Component mounting system

A component mounting system comprising:

• a component mounting machine configured to execute a mounting job taking out and mounting components supplied from a feeder mounted on any of multiple attachment target sections,
• the component mounting system for managing multiple mounting jobs to be executed by the component mounting machine, the component mounting system further comprising:
• an execution procedure determination section configured to obtain a sum value or a lowest value of a ratio of components used in common between previous and subsequent successive mounting jobs when the component mounting machine respectively executes the multiple mounting jobs in multiple assumed procedures, and determine the execution procedure of the multiple mounting jobs based on the sum value or the lowest value respectively obtained in the multiple procedures;
• and
• a job switching section configured to hold, in the attachment target section, a feeder accommodating a component common to a component used in the subsequent mounting job among components used in the previous mounting job when the previous and subsequent successive mounting jobs in the execution procedure determined by the execution procedure determination section are switched, and mount, on an empty attachment target section that is a attachment target section emptied among the multiple attachment target sections, a feeder accommodating a component not common to a component used in the previous mounting job among components used in the subsequent mounting job.
