Methodology for an integrated life cycle approach to design for environment

Abstract

To ensure that the economic and environmental impact over the entire product life cycle is taken into consideration during the design process, an integrated life cycle approach to Design for Environment (DfE) must be taken. In this paper, we describe the application of the product structure-based methodology for integrated life cycle analysis as a DfE decision-support tool. While maintaining an integrated perspective of the product life cycle, this methodology modularises the product life cycle model to the individual parts of the product structure; thus, allowing product designers to analyse the parts independently from the rest of the product system and enabling them to systematically evaluate the design alternatives. Using a case study on a dive torchlight, we demonstrate how through our proposed methodology, design alternatives for the product can be evaluated based on the life cycle eco-efficiency. ©(2014) Trans Tech Publications, Switzerland.
