Abstract: Wire-harness pre-assembly is an important step in wire harness production. This
paper presents an automatic wire harness pre-assembly planning method by means of
summarizing engineering semantic constraints in wire harness technological design and
establishing assembly incidence graph. This method realizes planning wire harness pre-assembly
sequence through main-connector selection, largest subassembly extraction and engineering
semantic constraints detection without users’ alternation. The practical application examples show
that the automatic wire harness pre-assembly planning method presented in this paper is effective
and feasible, and it can solve the assembly sequence planning problem in large wire harness
graphs.
