3D矢量空间和最优最劣法在绿色产品设计决策方法中的应用OA北大核心CSTPCD

In order to solve the problem of lack of consideration of basic product attributes and lack of visual comparison methods in current green product design schemes,a multiple attribute decision-making method for green product design based on 3D vector space and Best Worst Method(BWM)was proposed.Firstly,the model is constructed as a 3D vector space through the three dimensions of function,exterior and sustainability for the basic attributes of green product design,and the lower-level attributes of each dimension was expanded.Secondly,BWM that in-corporates the interval method was used to obtain the weight distribution of the three dimensions and the lower-level attributes of each dimension.Then,the overall evaluation score of each alternative was obtained through the 3D vector space to realize the objective and scientific multi-attribute decision-making of green product design.Finally,the feasibility and effectiveness of the proposed method was verified by taking the green product design scheme of electric vehicles as an example.
