A modular design strategy considering sustainability and supplier selection

Abstract

To utilize the residual value, which remains an idle asset and disposed product based on the circular economy package, the definition or clarification of such a value and the development of a scheme for such a reutilization is essential. In addition, to facilitate an efficient utilization of the residual value, a product or its components needs to be designed considering its future reuse, remanufacturing, and upgrading. When companies monitor product usage using the Internet of things, they can make proposals to users of appropriate lifecycle options such as reuse, remanufacturing, and upgrading and such proposals are conductive to customer retention for these companies. Therefore, an ideal situation is one in which the product is appropriately modularly designed and its components will be reused in an upward product or another product family or be recycled at the end of life. A designer needs to consider resource efficiency not only in the reuse stage but also in the production and procurement stages. In addition, a company that designs and manufactures products needs to strive for the simultaneous attainment of cooperate social responsibility, higher profits, and higher user satisfaction. Therefore, proper supplier selection is necessary because products currently consist of many components and modules manufactured by various companies. This study proposes a modular design and a strategic evaluation method based on the viewpoint of supply chain management considering sustainability and supplier selection simultaneously. In particular, the proposed method evaluates the designed modular strategy from the perspectives of cost, environmental load in production and transportation, quality, and procurement lead time. As an evaluation, the proposed indicator evaluates the efficiencies of the candidate suppliers. This study applied the proposed method to the design problem of a laptop module and determined the more appropriate suppliers with respect to each destination.

Circular Economy and Internet of Things: Mapping Science of Case Studies in Manufacturing Industry

“…Inoue, M.; Yamada, S.; Miyajima, S.; et al [42] Proposes a modular design and a strategic evaluation method based on the viewpoint of supply chain management considering sustainability and supplier selection simultaneously. The proposed method evaluates the designed modular strategy from the perspectives of cost, environmental load in production and transportation, quality, and procurement lead time.…”

“…In addition, the Engineering, Manufacturing, and Mechanical knowledge domains are presented, for example, at the research of modular design and a strategic evaluation method considering sustainability and supplier selection [42], as observed at (a) clusters one (red) and (b) four (yellow); and at the investigation about the decision support model for economical material-based carbon recovery [43], as observed at (c) clusters one (red) and (d) three (blue). Regarding the Green and Sustainable Science knowledge domains, the subject of the studies are business models for re-distributed manufacture employing additive manufacturing [47], as observed at (e) clusters two (green) and (f) four (yellow), and other research is related to the usage-focused servitized business model [35], as observed at (g) cluster four (yellow).…”

“…The fifty-eight authors with the greatest total link strength were selected and distributed in eleven clusters as revealed in Figure 11. The groups that stand out are: (a) cluster one, which is represented by the group of Inoue et al [42], and (b) cluster two, which is represented by the group of Fisher et al [36].…”

A Method for Remanufacturing Process Planning and Control Using Loosely Coupled Systems

“…Similarly, Pandey et al have applied DSM in an effort to assess remanufacturability and incorporate this at the design stage [44]. In a recent effort, Inoue et al proposed a DSMbased design method focused on sustainability in which ensuring remanufacturability as a key focus [45].…”
