A hierarchic metric approach for integration of green issues in manufacturing: a paper recycling application

This paper presents a hierarchic framework for environmentally conscious design. The framework integrates both product designers and stakeholders to evaluate not only the product features but also its environmental burden. In evaluating the product's burden, a life cycle assessment of the product is conducted through input-output analysis so that a comprehensive inventory of the product's actions and reactions to the environment could be documented. The analytic hierarchy procedure (AHP) is used to develop priority indices for customer requirements to highlight key features that must be present in the product. Subsequently, the quality function deployment is used to match design requirements to customer requirements. A cost-effective design plan is then finally developed. This framework adopts a systemic approach and ensures that environmentally conscious products are designed and manufactured.
