Approaches and Challenges in Product Disassembly Planning for Sustainability

Due to the vast variety of products and end-of-life uncertainties of used products, product disassembly remains as a challenging research area. This paper aims to address the gap between sustainable product development and product life cycle through optimizing disassembly in each stage of the product life cycle. Firstly, a comprehensive review on design concepts for product development and relevant disassembly planning methodologies at the different phases of a product life cycle, such as Design for Disassembly (DfD), product service system (PSS), disassembly sequence generation (DSG), and reconfigurable disassembly systems (RDS) is presented. Next, a conceptual framework that leverages on emerging technology driven by Industry 4.0 and product family approach to facilitate product disassembly planning for sustainability is proposed. Lastly, a short summary on different challenges presented as well as the respective future work are elaborated.
