Assembly modeling for the integrated system of assembly sequences planning and DFA

Aiming at product assembly design and optimization in concurrent engineering, we present an integrated product assembly analysis system of assembly sequences planning (ASP) and design for assembly (DFA). The assembly modeling method suitable for this integrated system is studied. A more complete assembly model is designed. Apart from the assembly draft and liaisons diagram information, the assembly tree structure, parts parameters and liaisons parameters, etc., are also included in this assembly model. An example is given to illustrate the computerization of this modeling method.
