Abstract: Aiming at the hop problem in case classification of low carbon product design which caused by dynamic product requirements,a case classification method of low carbon products design based on multidimensional association function was proposed to mine the transformation rules of cases classification.By analyzing the association feature in product lifecycle,an integrated quantitative method for carbon footprint and cost of consumed resource was established,and a low carbon product design case base was built.According to the calculation of similarity and frequency,the low carbon products design case base was reduced to obtain the classification case base.On this basis,the similarity calculation method based on multidimensional dependent function was built to achieve static classification.The extension dependent function for changed requirements was established to find dynamic influence caused by changing requirements.By taking low carbon design of LG series screw compressor(LG-6.7/10)as an example,the feasibility of proposed method was verified based on software platform such as Solidworks,VC++ and Access.
