中文摘要：

在客户协同产品开发模糊前端阶段,为提高创意知识获取的准确性,提出了一套基于模糊概念分析和模糊认知图的创意知识获取方法,其针对创意知识发散、多样等特点,结合模糊概念分析与本体理论对不同创意知识提出了考虑粒度的知识表达方法,解决了客户协同产品开发模糊前端阶段创意知识难以准确描述问题;针对创意知识模糊特点,提出了基于模糊认知图的创意知识模糊本体相似度度量方法,其度量值为是否应该获取该创意知识提供了量化依据.最后,通过实例,验证了该创意知识获取方法的准确性.

英文摘要：

In order to improve the accuracy of creative knowledge acquisition in fuzzy front end(FFE)ofcustomer collaborative product development,an acquisition method was proposed through combining thetheory of fuzzy formal concept analysis(FFCA)and Fuzzy Cognitive Map,etc..In terms of their divergent,novel,diversity,etc.characteristics,a knowledge representation method considering knowledge granularitywas put forward through combining FFCA and ontology theory,this method could be used to deal with therepresenting difficulty of creative knowledge acquisition in FFE.In terms of the fuzzy characteristic,a similaritymeasuring method of creative ontology was proposed also,whose result would provide effectivefoundation to decide whether the creative knowledge could be acquired or not.Finally,the effectiveness ofthis knowledge acquisition method was verified through an example.
