An EDS production system includes a material supply section for supplying electric wires and terminals, an EDS fabrication section having identified machines for processing electric wires to prefabricate circuits employable to fabricate EDS products, covering work regions for cutting electric wires in lengths, for stripping cut wires of insulating covers over lengths at either wire end or both wire ends and for applying terminals to stripped wire ends, and a production control section for controlling quantities of circuits to be prefabricated by completion dates therefor in consideration of quantities of ordered EDS products to be completed within delivery terms thereof, a master controls data on specifications for the electric wires, a combination of masters control data on specifications for the performances and work regions of the identified machines, and a processor processes a combination of data from the respective masters and data from the production control section covering the circuit quantities and the completion dates, to have allotted, to the identified machines, fractions of an entirety of circuit fabrication work to be done within an arbitrary time section in a concerned term to provide necessary types of circuits in required quantities by specified completion dates.
