Sparse principal component analysis based sustainability assessment of EOL ICT service infrastructures

摘要

Sustainable Design and Manufacturing (SDM) is becoming a more effective approach to solve sustainable (environmental, social and economic) problems. Information and Communication Technology (ICT) positively made business more efficient and less polluting, while negatively contributes to environmental impacts by releasing of Greenhouse Gases (GHG) and producing e-wastes. This paper will develop a quantitative method of sustainability assessment in all three dimensions based on Sparse Principal Component Analysis (SPCA). A prototype model of Sustainability Performance Assessment Tool (SPAT) that can be integrated with existing systems and software to aid in product and process decision making is developed and discussed in detail in this paper. A DSL modem is taken as a case study to demonstrate the sustainability assessment and prototype model.
