Cultural and creative products are incredibly diverse that difficult to mass-produce and fail to meet market demands. The unique characteristics and the cultural and sales value of cultural and creative products must be highlighted through the application of multifunctional design. As a scientific approach, the Delphi method and fuzzy logic theory were applied to create a multiattribute DFuzzy decision model for cultural and creative product design. This model is intended to enable objective, quantitative auxiliary decision evaluation for product design, providing a reference for optimization of commodity production. Fuzzy logic is one of artificial intelligence (AI) technologies and quantifies the fuzzy semantics of human languages. The Delphi method enables group decision-making among experts, thus contributing to the scientific and objective nature of the DFuzzy model. The 16 Delphi experts invited to participate in this study were the chief executive officers in the cultural and creative industry, local cultural management commissioners, and domain knowledge professors, all of whom had at least 12 years of experience in cultural and creative industry development. The experts reached a consensus regarding 19 preliminary criteria identified through a three-round Delphi process. The four criteria suitable for the DFuzzy model were determined to be cultural images, innovation and creativity, customer demand, and city charm. The model was then applied to evaluate three cases, a multifunctional scale ruler, a toy robot, and an agricultural specialty product. Another consensus was then reached by the experts through a two-round Delphi process, and the four criteria were validated. Thus, the objective quantitative calculation function of the DFuzzy model was confirmed along with its applicability for auxiliary decision-making in cultural and creative product design and education.

文创产品种类繁多，难以批量生产，无法满足市场需求。必须通过多功能设计的应用，突出文化创意产品的独特性和文化和销售价值。作为一种科学方法，运用德尔菲法和模糊逻辑理论，建立了文创产品设计的多属性DFuzzy决策模型。该模型旨在为产品设计提供客观、定量的辅助决策评价，为优化商品生产提供参考。模糊逻辑是人工智能 (AI) 技术之一，可量化人类语言的模糊语义。Delphi 方法使专家之间的群体决策成为可能，从而有助于 DFuzzy 模型的科学性和客观性。受邀参与本次调研的16位德尔福专家分别是文化创意产业首席执行官、地方文化管理专员、领域知识教授，均拥有至少12年文化创意产业发展经验。专家们就通过三轮德尔福流程确定的 19 项初步标准达成了共识。适合DFuzzy模型的四个标准被确定为文化形象、创新创意、客户需求和城市魅力。然后将该模型应用于评估三个案例，多功能秤尺、玩具机器人和农业特产。然后专家们通过两轮德尔菲过程达成了另一个共识，并对四个标准进行了验证。从而证实了DFuzzy模型的客观量化计算功能及其在文创产品设计和教育辅助决策中的适用性。
