英文摘要：

To realize disassembly complicated product＇s hierarchy, sequence planning with quick interpretative structural model and accurate determination of （ISM） is introduced into the description of complicated products, and a method of product disassembly sequence planning is put forward. With the analysis of component connection extraction and expression, component connection adjacency matrix and directed graph, product＇s component connection model is established on the basis of ISM. By calculating ISM connection reachability matrix, its directed graph is established and a product component structure depth＇s calculation and disassembly sequence planning method is given. Finally, the proposed method is illustrated and verified with an example of the door of dish-washing machine. The proposed planning method is effective in defining complicated product＇s structure hierarchy quickly, thus, the disassembly sequence can be generated.
