The machine tool apparatus comprises: multiple work machine modules configured to sequentially perform a series of manufacturing-related operations on a workpiece; a robot configured to convey the workpiece between the multiple work machine modules; an individual information-providing device configured to provide an individual information to the workpiece conveyed into the multiple work machine modules and subjected to manufacturing-related operations; a storage device; and a control device configured to link the manufacturing history of manufacturing-related operations performed on the workpiece by the multiple work machine modules and store the information in the storage section, the workpiece being a workpiece to which the individual information was provided by the individual information-providing device.

A production schedule creating method includes: acquiring production sequence information including a production sequence for producing a plurality of models of products and preparation work sequence information including a sequence of arrangement work of arranging members corresponding to the plurality of models on arrangement means which is attached to production equipment so as to arrange the members that are used for production of the products; acquiring arrangement means information including production arrangement means information that is information of the arrangement means attached to the production equipment and equipment detached arrangement means information that is information of an equipment detached arrangement means that is not attached to the production equipment; optimizing a production schedule obtained after a time point of acquisition of the arrangement means information, based on the production sequence information, the preparation work sequence information, and the arrangement means information.
