摘　　要：为了将产品设计开发中选择备选方案和进行决策的过程有效地结合起来,提出一种基于设计理性的群体一致性产品方案决策方法.首先通过提取文本信息和数值信息将设计理性的设计意图转变成特征向量,并选取与设计问题相似性较高的设计意图对应的设计理性作为备选设计方案;然后决策者利用直觉模糊集对方案进行评价,计算个体和群体决策之间的相似度,采用一致性阈值衡量决策是否达到共识水平;最后通过广义诱导模糊有序加权平均算子,集结专家意见得到各方案的综合评价结果.以某型焊钳的钳臂设计为例,验证了文中方法准确性和有效性.In order to combine the process of alternatives obtaining with the process of decision making in product design and development, a method for product scheme decision making of group consensus based on design rationale is proposed. Firstly, through the extraction of text information and numerical information, the design intention can be transformed into feature vector, and the design rationale corresponding to the design intention with higher similarity of design problem is chosen as the alternative design scheme. Then, decision makers use intuitionistic fuzzy sets to evaluate the alternatives, calculate the similarity between individual and group decisions, and uses consistency thresholds to measure whether decisions reach consensus levels. Finally, the generalized inductive fuzzy ordered weighted averaging operator is used to aggregate the expert decisions, and the comprehensive evaluation results of these schemes are obtained. In the design of a certain type of welding clamp arm as an example was used to verify the accuracy and effectiveness of the proposed method.
