This article transforms the disassembly graph model into a disassembly matrix model, and plans the path of selective
disassembly by solving the matrix model.By conducting selective disassembly research on key components, a disassembly path is planned.
When disassembling key parts, the goal is clear and unnecessary disassembly steps are omitted, greatly shortening the disassembly time and
improving disassembly effi ciency.This article presents the results of this study through a case study, proving that the results can transform
complex component connection diagrams into matrices, and then plan the disassembly path of key components
