ELV Recycling Management Practice: A Disassembly Mode Selection Using a Hybrid MCDM Approach

Abstract

To assist sustainability achievement of the Chinese vehicle industry, a 4R-based recycling procedure (re-use, recovery, re-manufacturing and material recycling) is constructed and end-of-life vehicle recycling (ELV) management practices are performed recently. The prerequisite of cost-effective 4R operations is the dismantling of ELVs, therefore, the appropriate disassembly mode employed is of great significance for recycling efficiency improvement. The disassembly mode selection subjected to multiple principles can be regarded as a multi-criteria decision-making problem, and we develop a hybrid fuzzy DANP-VIKOR approach to perform the recycling management practice through the disassembly mode selection. The fuzzy DANP method is employed to map the multiple criteria in terms of the vagueness and uncertainty, and the derived fuzzy weight vector is embedded into fuzzy VIKOR steps. To avoid loss of information, the fuzzy ranking technique based on degree of possibility concept is proposed to obtain the alternative ranking. A case study in a recycling plant demonstrates the effectiveness and robustness of the hybrid approach.
