Evaluation model for non-functional requirements intrustworthy software based on design structure matrix
基于设计结构矩阵的可信软件非功能需求评估模型

It is an important field to evaluate non-functional requirements NFRs quantitatively in trustworthy software TS. Based on the interdependent relations of NFRs inside the components, according to the design structure matrix, matrix shift and calculation, this paper presented the relative quantity of NFRs inside components, which helped to build the relational matrix between components and NFRs and to bring a calculation model of NFRs that had unified standard and estimated measure. And based on the model, it produced a decision method which could judge whether the NFRs accord with the anticipation of the software developers and user. At last, this paper demonstrated the rationality and validity of this model through a real case.
