Abstract: Life cycle assessment (LCA), as a quantitative assessment tool for environmental performance in green design, is used widely in decision-making of product design. However, apparently, it’s not sufficient to make final decision only depending on environmental assessment results for profit-directed organizations. The aim is to propose a methodology for integration of LCA and life cycle costing (LCC). A framework of integration of LCA and LCC is introduced. An inventory analysis algorithm based on matrix is designed to realize to take timing of effects into account in inventory analysis, and a mathematic model integrating environmental and economic performance is set up. Concurrent subspace optimization (CSSO) algorithm is applied to optimize this model so as to achieve the win-win goal of economic and environmental benefit, which provides a quantitative basis for the improvement of initial product design. A case study of type 4135G diesel engine demonstrates the validity of the proposed methodology.
