摘要/Abstract

摘要： 针对创新设计模糊前端的认知计算问题，从信息处理研究的角度，借助口语数据来表征团队设计认知信息，提出了设计认知复杂度分析及计算方法。从设计的过程、内容、团队和方法四个方面阐述设计认知行为的复杂特性，并以链接表结构化表达设计推理的过程及概念信息，结合熵信息和确定性信息理论来描述设计认知，在新定义的链接矩阵的基础上实现T-code解析算法分析，对设计认知推理的不同阶段、概念分布、关键概念等方面开展设计认知的复杂度、信息量和信息熵研究。以功能背包设计为实例，对比分析设计认知敛散过程与设计概念空间的布局特性，验证了此计算方法的有效性和可行性。

Abstract: Aiming at the cognition compuatation problems for fuzzy front end of innovation design, the information on design cognition was presented by the oral data and the complexity analysis and computation method were proposed through information processing. Firstly, the complexity of design cognition behaviors from four sides including the process, content, team and approach of design was elaborated. By structurally representing the data and information in the form of linkography, the description on design cognition was made through combination with DIT. Furthermore, the T-code parse algorithm was illustrated on the basis of the definition on the new link-matrix. The analyses of cognition complexity, the information amount and the information entropy were carried out for different stages of design reasoning, the concept distribution and the key concepts. Finally, by taking functional backpack design as an example, the layout characteristics of the design concept and the design processes of convergence and divergence were compared, the effectiveness and feasibility of the method were proved.

Key words: design cognition, complexity, linkography, deterministic information theory(DIT)
