1. A system for performing work processes on workpieces, comprising:
at least two first process stations, each configured to perform a first work process on at least one workpiece with a first process duration;
at least one second process station configured to perform a second work process on the at least one workpiece with a second process duration, wherein the first process duration and the second process duration are of different lengths;
a transport surface on which the at least one workpiece are movable individually on transport units using electromagnetic drives, wherein the transport units are configured to take over the at least one workpiece from a first conveying device in a region of a takeover zone, subsequently feed the at least one workpiece to a first process station of the at least two first process stations and then to a second process station of the at least one second process stations, and transfer the at least one workpiece to a second conveying device in a region of a transfer zone;
transport paths for the transport units between the takeover region, the first and second process stations, and the transfer region, wherein the at least two first process stations are arranged one behind the other or one after the other with respect to the transport path of a transport unit when viewed in a transport direction of the transport units, wherein, between the takeover region and the transfer region, a travel route continuously free of process stations is formed for the transport units, a width of the travel route corresponding to at least the width of a transport unit; and
a control device configured to control the transport units, the control device being configured to control the transport units depending on an availability of free process stations to approach the first and second process stations with a view to a lowest possible total process duration of the at least one workpiece to be processed, taking into account any required order of performing the first and second work processes.
