摘　　要：产品的设计方案优选是个复杂的多准则团队协同决策过程。为解决产品设计方案优选中多准则间的关联被忽视的问题,提出一种改进的Topsis方法模型,即通过Vague交叉熵建立起多准则下的单个专家评价结果模型,再应用证据推理理论融合各专家的冲突性的评价结果,得到各方案综合评价值,以判断出优解顺序。最后,以共享底盘开发的方案评价与选择作为实例验证了该方法的可行性与有效性。Optimization for product design plans is a classic multiple criteria group collaborative decision-making process with lots of uncertain factors involved.To solve the neglected problems between multi-criteria association during the selection of the product design schemes,this paper proposed an improved Topsis method,and established a single-expert-evaluation model under multi-criteria with Vague cross-entropy.Integrating evidential reasoning theory and conflicting evaluation results from different experts to get the comprehensive evaluation of the alternatives,to determine the optimum solution order.Finally,the assessment and selection of the share basis platform development verified the feasibility and validity of this method.
