软件质量度量元的理想取值区间反推技术

Technique to Deduce the Expected Ranges of Software Quality Metrics

针对软件质量度量元理想取值区间难以确定的问题，指出在推导一个度量元的理想取值区间时，应结合特定的（用户关心的）外部质量指标进行考虑，研究并提出了基于正交设计思想的度量元理想取值区间反推技术，该技术能够量化地给出度量元的理想取值区间，初步解决了度量元质量需求定义的问题。

： This paper aims at the problem of defining the expected ranges of metrics，points out that should not deduce the expected range of a metric separately，but also consider the issued outer quality indicator at the same time．It provides a technique，which is based on the idea of normal design，to deduce the expected ranges of software quality metrics．This technique can quantitatively give the expected ranges of metrics，primarily solve the problem mentioned above．
