Abstract: To realize supply chain low-carbon design of multi-granularity complex product,the triangular fuzzy number method and Hamming distance closeness method were improved to transform the low-carbon needs of main responsibility for supply chain.Euclidean distance method and TOPSIS method were used to obtain the multi-granularity product utility and the factor of carbon footprint.The granularity level and life cycle of low-carbon design product were selected by carbon design performance.Based on constructing of the main contradiction matrix which described mapping relationship of low-carbon needs and design measures,the technical conflict was eliminated by engineering parameters and invention principles,and the suggestions of low-carbon design was put forward.Through the example of liquid crystal display,the versatility of low-carbon design was increased effectively with proposed method,and the uncertainty was reduced.
