摘要：NFR determination of the software products is an important link in the requirement development. Considering the correlation and inter-dependence between FR and NFR of software, this paper puts forward a NFR system identification method of the software products based on the fuzzy-QFD model through constructing the FR-NFR correlation matrix of software. The model express correlation evaluation with the 7-level natural language, build the software FR-NFR correlation matrix, fuzzy the matrix vector by the trapezoidal fuzzy number, then calculate the relative importance and absolute importance of NFR, at last get the importance NFR by the NFR screening algorithm.
