中文摘要：

针对包含模糊语义描述的半结构化客户需求信息（SCN）具有模糊性、不易处理性，以及难以转换成精确的产品功能要求（FRs）等特点，研究了SCN的表达与转换处理方法．提出了SCN的数学描述方法和SCN转换问题的形式化描述方法，建立了SCN转换体系结构，通过模糊语义分析、智能模糊推理、加权优化及去模糊化等四个处理步骤，实现了半结构化客户需求（SCN）到精确产品功能要求的转换．最后以应用案例说明了该方法的实用性．

英文摘要：

In view of the characteristics of semi-structured customer needs （SCNs） with fuzziness and difficulty to be processed and converted to precise product functional requirements （FRs） , an expressing and transforming approach for SCNs is studied. The mathematical description approach of SCNs and the formal description approach of SCN transforming problem are presented, and then the architecture of the SCN transformation is constructed. This architecture is composed of four steps：fuzzy semantic analyzing, intelligent fuzzy reason- ing, weighted optimizing, and defuzzification. Precise product functional requirements satisfying SCNs are out- putted at last. Finally, the practicability of the approach is illustrated by an application case.
