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 disassembly sequence of products, a decision-making model of product disassembly sequence with Fuzzy Reasoning Petri Nets (FRPN) is proposed. And then, combined fuzzy reasoning Petri nets with matrix operation, a reasoning algorithm of formalized is adopted to discuss the model of decision-making. Finally, an example is used to illustrate the applications of the proposed methodology. The result shows that the model of decision-making has strong parallel operation ability in the disassembly process sequence. The model can make intelligent decisions based on the product information from each disassembly step. It can also realize the automatic clustering identification and decrease the complexity of product disassembly.
