Abstract: Quickly and accurately identifying each process and their constraint relations
between each other from the complex wiring harness drawings is the basis for formulating process
routes. According to the knowledge of automotive wiring harness and the process characteristics
of wiring harness components, the model of harness process graph is established. Then the
algorithm for identifying processes automatically is researched, finally the relationship between
procedures by introducing the constraint matrix is described to lay a good foundation for harness
process planning and production scheduling.

Key words: automotive wiring harness, wire harness graph, identification process, constraint
matrix
