Abstract Selective disassembly planning searches solutions to separate useful parts of a product to be reused or recycled at the end of the product life. An efficient method is essential for disassembly planning in the product recycling process to reduce the operation time and cost. This paper proposes an efficient method for selective disassembly sequence planning considering destructive operations. Different from the most existing methods that mainly consider the non-destructive disassembly, destructive disassembly operations are considered to improve the product recycling and operation efficiency. An efficient product representation approach and search algorithms are proposed to generate the optimal disassembly sequence plan. Multi-level constraint matrices based on products’ bill of materials are constructed to identify products’ structure to reduce the searching size of disassembly plans. An industrial mechanical arm is used in the case study to verify the proposed method.
