“…The processing techniques proposed in this paper are recycling and reusing. As noted by [28], these techniques are the best for computers. According to the [28], and the results of processing methods in the bill of materials (BOM) for a computer case study (48 usage months), It is observed that the #1 fan controller, #3 PCI board, #13 memory, and #14 motherboard have been selected for reuse due to their low reuse cost.…”

Factors considered in product design have a significant impact on future cost and sustainability. Some factors such as materials, dimensions, and tolerances are crucial in the design process of many products. At the macro scale, this can give rise to environmental effects and influence the reliability and sustainability of the product. In this research, a hybrid system dynamics simulation-optimization approach has been proposed for tolerance design. In this approach, first, the optimal values of tolerance and price are determined by conjoint analysis. These values are entered into a system dynamics model to evaluate the relationships among sustainability, reliability, and customer satisfaction. Then, the impact of tolerance and other factors of product design on sustainability, reliability, and customer satisfaction are investigated. This approach can help decision-makers better understand the trade-off between design factors, resilience, sustainability, and customer satisfaction and make more informed decisions. The proposed method is illustrated for computer assembly step by step. The results show that lower sustainability and higher customer satisfaction are directly associated with tighter tolerances. Besides, lower sustainability, higher reliability, and higher customer satisfaction are associated with lower quality of materials. The validity of the model was examined using a boundary-adequacy test.

“…In the context of environmental soundness and economic effectiveness in the production and operations management umbrella, studies conducted by Song et al (2018) and Hasegawa et al (2019) contributed largely in understanding the role of environment and economy in decisions related to improving performance in general. For one, Song et al (2018) referred to the theory on total factor productivity (TFP) to analyze the impact of fiscal decentralization and environmental regulation on assessing economic and environmental development in a region using a slacks-based measure model.…”

“…On the other hand, Hasegawa et al (2019) argued that the environmental impact of a life cycle option should be considered as equally important as the optimal cost for disassembly methods. Therefore, the authors looked into the life cycle option selection based on the multivalue circulation model with objective functions being on optimized cost and recycling rates.…”

“…However, assembled products, such as electronic products, are often disposed of as waste even when they retain some useful components and materials that can be recovered by reuse and recycling as the End-of-Life (EOL) stage [2]. Life cycle option selection involves the reuse, recycling, and disposal of each component by disassembly [3,4]. These options can prevent the wastage of virgin materials and GHG emissions by reutilizing the components.…”

The depletion of natural resources and global warming have increased in severity globally. In the industrial field, assembly products, such as electronic products, should be disassembled for recycling and reuse to deal with these problems. Reuse and recycling can contribute to reducing GreenHouse Gas (GHG) emissions and less depletion of natural resources since GHG emissions for virgin material production can be saved using reused components and recycled materials. However, each component of selling revenue and material-based GHG emissions depends on the country because of the different energy mixes of electrical power. Moreover, each collected component embedded in End-of-Life (EOL) products needs to be selected as a life cycle option based on its remaining life. The purpose of this study is to decide life cycle options such as reuse, recycling, and disposal of each component environmentally-friendly and economically in Korea and Japanese cases for computers. Firstly, selecting the life cycle option for each component was formulated by 0–1 integer programming with ε constraints. Next, GHG emissions, profits, and costs in Korea and Japan were estimated and analyzed for each component. Finally, Korean and Japanese cases were analyzed to obtain an economic value in the same material-based GHG saving rate with each component’s life cycle option selection by comparing each EOL product data. In the experiments, GHG recovery efficiency was higher in Japan 43 [g/Yen] than one in Korea 28 [g/Yen]. Therefore, it was better to retrieve and reutilize the components in Korea. However, if the maximum GHG recovery efficiency is desired, Japan is a better option.
