摘　　要：为了解决目前产品概念设计方案中系统层级结构考虑欠缺以及多属性之间无相互联系的问题,提出一种基于概念层次开发(Concept hierarchy development,CHD)的产品概念设计多属性决策方法。首先,通过CHD理论将各备选产品概念设计方案的图像划分为模块部件、角度视图、物理属性三个设计层次开发,构建每个层次开发中多属性准则之间的相似度比较矩阵。进而利用毕达哥拉斯模糊集(Pythagorean fuzzy sets,PFS)和前景理论(Prospect theory,PT)相结合的方法,得到各决策专家及设计准则的权重分配,从而实现客观合理的产品概念设计多属性决策。最后以响堂山佛像益智玩具的产品概念设计方案为例,验证了该方法的可行性和有效性。In order to solve the problem of poorly considering a system′s hierarchical structure in the current product conceptual design plan and the lack of interrelationship between multiple attributes, a multi-attribute decision-making method for product concept design based on concept hierarchy development(CHD) was proposed. Based on the CHD theory, the method divides the image of each candidate product′s conceptual design plan into three design levels: module component, angle view, and physical attribute.The similarity comparison matrix betweenmulti-attribute criteria at each level of development was constructed. The method of combining the Pythagorean fuzzy set(PFS) and theprospect theory(PT) was used to obtain the weight distribution of decision experts and attribute criteria and realize the objective and reasonable multi-attribute decision-making for product conceptual design. Finally, the feasibility and effectiveness of the method was verified by taking product conceptual design schemes of Xiangtangshan Buddha educational toys as example.
