Component replenishment management system and component mounting system

A component replenishment management system that manages a replenishment of component storage members storing components with respect to each of a plurality of component supply devices attached to a mounter that mounts the components on a substrate to produce a mounted substrate, a plurality of the component storage members being loadable into each of the plurality of component supply devices, the component replenishment management system comprising:

• an acquisition unit configured to acquire a management start time expressing a start time of the management of the replenishment of the component storage members with respect to each of the plurality of component supply devices;
• a setting unit configured to set a specified period until a specified time after a predetermined specified length of time has elapsed from the management start time;
• a component supply monitoring unit configured to monitor a supply status of the components in each of the plurality of component supply devices, and specify, for each of the plurality of component supply devices, a replenishment possibility time at which a preceding component storage member used to supply the components from among the plurality of component storage members runs out of components and replenishment with a new component storage member becomes possible;
• and
• a replenishment target specifying unit configured to specify a component supply device whose replenishment possibility time is an earlier time than the specified time as a component replenishment target device targeted for replenishment with a new component storage member within the specified period.
