A numerical control apparatus that is a selection apparatus causes, when an automatic lathe that fabricates a workpiece from a bar is unable to fabricate a workpiece that is a fabrication target from a remaining material that is a remaining part of the bar being machined, the automatic lathe to select another workpiece that the automatic lathe is able to fabricate from the remaining material. The numerical control apparatus includes a selection unit to select, when there are a plurality of other workpieces that are able to be fabricated from the remaining material, a workpiece to be fabricated on the basis of a length of the remaining material and priority.
