1. A production system comprising:
a production apparatus having
i) one or more production tools for manufacturing components, wherein parameters of the production tools include one or more of laser beam intensity, laser beam focus, bending tool used, throughput speed, feed speed, pulse ratio during pulsed operation, power, and energy, and
ii) one or more carriers or transport aids, or both carriers and transport aids, arranged and configured to transport the components between the production tools;
a controller arranged and configured to control the production apparatus on the basis of production data;
a locating system for localizing a mobile unit arranged or embodied on any one or more of the carriers, components, production tools, or transport aids, wherein the locating system is configured to
i) determine the position of the mobile unit,
ii) detect identification information stored on the mobile unit and to communicate the position data thus determined of the one or more of the carriers, components, production tools, and transport aids to the controller, or
iii) both i) and ii); and
a digital model of the production apparatus that provides a simulation of production sequences, wherein the simulation is based at least on the data of the locating system,
wherein the production system comprises a model library having simulated production sequences, actually implemented production sequences, or both simulated and actually implemented production sequences, wherein the controller is configured to compare the production sequence simulated in the digital model with the production sequences of the model library, and
wherein at least one production tool of the production apparatus comprises a loading zone for loading and unloading a carrier or transport aid, wherein the production system comprises an image recording unit configured to capture image information in the loading zone, and wherein the locating system comprises an image evaluation unit configured to determine a loaded or unloaded state of a carrier or transport aid using the image information.
