Study on disassembly sequence decision making for products recycling and remanufacturing systems

The disassembly sequence decision-making for used products is extremely important for recycling and reuse of components. In order to calculate the analysis difficulty of disassembly path in deciding on the disassembly sequence of products, a decision-making model of product disassembly sequence with Fuzzy Reasoning Petri Nets (FRPN) is proposed. Combined with the matrix operation, a formalization reasoning algorithm is adopted to calculate the disassembly sequences. The result shows that the model of decision-making has strong parallel operation ability in the disassembly process sequence, and can make intelligent decisions based on the product information from each disassembly step. It also realize the automatic clustering identification and decrease the complexity of product disassembly.
