PROBLEM TO BE SOLVED: To improve production efficiency by manufacturing a substrate preferentially using a term approaching member which is approaching a term of validity and by using the term approaching member before the expiration of the term of validity.SOLUTION: When a term approaching component which is approaching a term of validity is confirmed among components used in production of component mounting substrates, a lane LA in which a preferential substrate on which the term approaching component is mounted among substrates is transferred is determined as a preferential lane and mounting of a component to a substrate in the preferential lane LA is preferentially executed. Thus, the term approaching component which is approaching the term of validity is preferentially used and the term approaching component is used before the expiration of the term of validity. Consequently, disposal of a component due to the arrival of the expiration can be suppressed and production efficiency can be improved. |
