PROBLEM TO BE SOLVED: To give a notification of component shortage in consideration of arrangement, with respect to the replenishment of circuit component required for mounting on a substrate.SOLUTION: Based on a production schedule that defines the quantity of substrates per product type to be produced and the production sequence for the current and future production, the expected time of component shortage is calculated concerning each feeder 26 attached to a component supply section 6. Then, if the expected time of component shortage is later than the finish time of a production job in progress for production, and further the expected time notified as a component shortage time is before the finish time of the production job for the type of substrate in progress for production, judgment is made as to whether the type of the circuit component stored in the feeder 26 is to be used in the subsequent production job. If the foregoing component is to be used, component shortage is notified in the implementation stage of the production job of the types of substrates in progress for production. |
