Abstract: The accelerating speed of product upgrading has led to an increasing number of end-of-life products. Proper disassembly and recovery of end-of-life products have become an important way to develop sustainable manufacturing. To solve the problem of disassembly planning of end-of-life products, the parts recovery evaluation is integrated into the decision-making process of the disassembly sequence and disassembly length. Comprehensively consider a number of evaluation indicators/criteria that affect the recovery efficiency of internal parts of end-of-life products and the interaction between these evaluation indicators/criteria to establish a parts recovery comprehensive evaluation model. Based on the parts recovery comprehensive evaluation model, a disassembly sequence and disassembly length integrated decision-making method is proposed, and the evaluation value of parts recovery efficiency is used to quickly determine feasible and high-quality disassembly sequence and disassembly length to maximize therecovery efficiency of end-of-life products. A power battery and randomly generated end-of-life products of different scales are applied to verify the feasibility, effectiveness of the proposed model and method. The computational results show that the advantages of the parts recovery comprehensive evaluation model and disassembly sequence and disassembly length integrated decision-making method in calculation efficiency will increase with the expansion of the scale of end-of-life products.
