On the basis of analyzing and summarizing the research of the planning of assembly sequence made by scholars in the past, and by synthesizing the characteristics of methods of disassembly and preference constraint, a kind of new analytical method for assembly sequence has been discussed. Utilizing the information of product's assembly region and carrying out decomposition upon the product according to cut-set method of graph theory, this method establishes the constraint relation of geometrical preference, and then builds constraint relation of technological preference through the mode of man-computer interaction, finally the feasible assembly sequence of product is obtained. The plan of product's assembly sequence is achieved based on CAD under integration circumstance. Block-diagrams of generation algorithm of cut-set and of algorithm of assembly sequence plan were presented, and finally they were verified through living examples.
