Product' s Level Construction Tree Model and the Method of Generating Disassembly Sequence

Disassembly sequence is the basis of disassembly and recycling and one of the key technologies of green product design. In order to get disassembly sequence, presenting the level construction tree model of product and defining restriction matrix, studied on generating of product's disassembly sequence, and providing rules of generating disassembly sequence, obtained the method of generating product's disassembly sequence. This method deal with the restrictions and limits of parts before disassembly, hence make disassembly more like the situation of the fact, limit the quantity of disassembly combinations, enhance the efficiency of disassembly and make disassembly more easier.
