Abstract

In a system for preparing a wire harness production, a modified wiring pattern generator generates modified wire harness wiring pattern information related to at least one second pattern in which at least one of parts, electric circuits, and wirings of a first pattern including the parts, the electric circuits, and the wirings of a standard type vehicle is altered. A parts information storage stores parts specification information including specifications of the parts, the electric circuits and the wiring included in the second patterns. A simulator simulates whether each of the second patterns is practical while referring to the parts specification information. A sub wiring pattern modifier modifies at least one of first sub patterns constituting the first pattern to at least one of second sub patterns so as to constitute the second pattern judged as practical by the simulator. A jig arrangement pattern information generator generates jig arrangement pattern information related to jig arrangement patterns prepared by applying at least one sub jig arrangement pattern to each of a plurality of wire harness path patterns of the standard type vehicle included in wire harness path pattern information. Path decision information selects one wire harness path pattern among the plurality of wire harness path patterns. Alternation information indicates at least one of alternation portions altered from the first pattern. A jig arrangement pattern selector selects one jig arrangement pattern corresponding to the selected wire harness path pattern among the plurality of wire harness path patterns. A path plan generator generates a path plan by integrating the modified second sub pattern having the alternation portions which is indicated in the alternation information and the selected jig arrangement pattern.
