Abstract: To realize rapid assembly process planning of complex product, concepts of assembly meta-connection and assembly meta-process, which were extended to assembly components and process tuples, were proposed based on analysis of assembly structure and process characteristics. Assembly meta-process and tuples were constructed by expressing their composition with object-oriented technology and analyzing attribute rule mapping of assembly meta-connection and assembly meta-process. To improve the efficiency of assembly process planning, a three-phase approach to implement assembly meta-process design and assembly process planning based on meta-process were presented. Validity of the proposed method was verified by the instance of assembly process design for a single-stage gear reducer and a prototype assembly process planning system module development.
