Research on Modularization Disassembly Sequence Planning based on Interference Matrix

Disassembly sequence planning is one of the most important works in Product repair. It is very easily cause combinatorial explosion when we disassemble complex machinery product. In order to solve this problem, we put forward modularization disassembly. We construct a modularization disassembly model where the Hierarchy Structure Graph of product is created. Then, we establish an interference matrix on every gradation to record the relationship in product part, and we can get disassembly sequence on every gradation by simplifying the interference matrix. At last, we get whole disassembly sequence by lining up the disassembly sequence on every gradation. Finally, a case study is also given to show that the method is feasible and effective.
