摘要： 提供了一种面向过程非功能需求处理方法，通过量化需求领域信息实现；对非功能需求目标进行分析得到目标优化树，在目标优化树中加入领域信息产生设计分析图，然后对图中领域信息结点进行量化赋以特定的量值，权衡各量值来选择合适的解决方案，还提供了简便的方法来支持系统升级。

Abstract: The quantifying method proposed is process-oriented, it manages non-functional requirements using quantifying the domain information. A non-functional goal refinement tree is generated during the goal refinement process, and then the domain information is incorporated into the tree. After quantifying the domain node, the best solution is selected through the analysis of the value of many different domain nodes. This method also supports system change.

Key words: Non-functional requirements, Quantifying, Goal-refinement, Domain information
