Disassembly Reuse Part Selection for Recovery Rate and Cost with Lifetime Analysis

Abstract

The depletion of natural resources is a critical environmental issue, and the recovery, including reuse and recycling, of end-of-life assembled products is the key to reducing the use of natural resources. However, in order to reuse or recycle an assembled product, it is essential to consider the life expectancy or material type and the weight of the parts in the product. In addition, because the assembled products comprise various parts, manual disassembly is required, which entails high costs. To recover assembled products in an environmentally friendly and economical manner, part selection for disassembly is required. A part selection method is proposed with three selection types: reuse, recycling, and disposal. First, data-set preparation is addressed. Second, the method for selecting the disassembly parts using integer programming and the ϵ constraint method is explained. Finally, numerical experiments are conducted using the proposed part selection method with a computer as a case study. Lifetime changes of the parts/product are then analyzed.

Reference Overview on Design and Simulation of Green Supply Chain Management

“…However, several factors can prevent companies from disassembling, e.g. the petite size of the components, the lower economic value of the disassembled components, and the high difficulty level for component recycling or disassembly [49]. Thus, the economic factor in the disassembly process should also be considered [50].…”

End-of-Life Product Recovery Optimization of Disassembled Parts Based on Collaborative Decision-Making

“…Disassembly papers can be classified to papers with and without life cycle option. In other words, some studies like [10; 11] have considered life cycle option while [12] did not study the life cycle subject. The authors only focused on reduction of disassembly costs and solving the presented mathematical model with a metaheuristics algorithm.…”
