| In this paper,The LCA system flame,disassemble sequence,the base theory of disassemble are discussed deeply and systematically. Simultaneously,the probably of disassemble sequence produced automatically has been researched. The main content as follows:1. The application of Data House and Petri web has been analyzed. Finally,the application progress and method of Petri web in Green Design system has been searched.2. The product disassembly information has been analyzed. Part disassembly restrict matrix is used to whether a part can be disassembled.3. According to the part relation degree,we have get the sub-assembly clustering. Following,The problem of disassemble sequence combination explode can be resolved efficiency.4. The system of disassemble sequence produced automatically is studied rather perfectly. |
