Abstract
Method for providing manufacturing-related data in the large-scale production of manufactured objects, in particular, automobiles, includes a data collecting device assigned to each manufactured object, with manufacturing-related data being input into the data collecting device at least in a part of the manufacturing sections of the large-scale production, and with the data being transmitted at least partially by the corresponding data collecting device to one central device during manufacturing. Manufacturing-related data consequently are made centrally available in the central device and can be used for planning possibly required subsequent work. The planning of subsequent work consequently can be carried out when the manufactured object is still located in the manufacturing process. This considerably simplifies the planning of subsequent work and makes it possible to save time and lower costs.
