Abstract: To solve the problem of much bigger solution space existing in the theoretic Disassembly Sequence Planning (DSP) algorithm, an approach based on engineering semantic information to generate the disassembly sequence was put forward. According to this algorithm, by using the engineering information such as the assembly restrictions and disassembly intervention status, the generation and path reasoning of product disassembly sequence planning was implemented, and the disassembly sequence was removed which was impossible from engineering viewpoint, so that the solution space was reduced. The algorithm ensured the consistence with the actual engineering situation, and the practicability and the programmable capacity were greatly improved.

Key words: disassembly sequence planning, design for disassembly, engineering semantic information
