Work plan management system and component mounting system

A work plan management system that manages a plan for setup work for producing a component mounted substrate with respect to a mounter that produces the component mounted substrate by mounting, onto a substrate, components supplied from a plurality of attached component supply devices into which a plurality of component storage members are loadable, the work plan management system comprising:

• a component replenishment management unit configured to manage a plan for component replenishment work, the component replenishment work being setup work that replenishes each of the plurality of component supply devices with a new component storage member;
• and
• an ancillary work management unit configured to manage a plan for a plurality of ancillary work performed during the production of the component mounted substrate, the ancillary work being setup work other than the component replenishment work, wherein
• the component replenishment management unit includes
• a component supply monitoring unit configured to monitor a supply status of the components in each of the plurality of component supply devices, and specifies, for each of the plurality of component supply devices, a replenishment possibility time window expressing a time window during which the component replenishment work is possible, and
• a replenishment target specifying unit configured to recognize an overlapping replenishment time window in which the replenishment possibility time windows overlap each other, and specify a component supply device for which the component replenishment work is possible within the overlapping replenishment time window as a component replenishment target device treated as a target of the component replenishment work, and
• the ancillary work management unit includes
• a work duration specifying unit configured to specify, for each of the plurality of ancillary work, a recommended work start time window expressing a time window in which the start of work is recommended, based on a work duration from a start until an end of each of the plurality of ancillary work, and
• a work start target specifying unit configured to specify, from among the plurality of ancillary work, ancillary work for which an earliest time of the overlapping replenishment time window is included in the recommended work start time window as start target work to be started within the overlapping replenishment time window.
