This paper discusses an approach for the top-down composition of software architectures. First, an architecture is derived that addresses functional requirements only. This architecture contains a number of variability points which are next filled in to address quality concerns. The quality requirements and associated architectural solution fragments are captured in a so-called Feature-Solution (FS) graph. The solution fragments captured in this graph are used to iteratively compose an architecture driven by quality requirements. Our versatile composition technique allows for pre- and post-refinements, refinements that involve multiple variability points, and functionality extensions. In addition, the usage of the FS graph supports Aspect-Oriented Programming (AOP) at the architecture level.

软件体系结构对软件的稳定性、软件维护和软件演化等各方面的性能很重要。该文引入构件运算的方法描述体系结构，分析调用运算、协作运算和条件运算的相关性和构件的复杂度，综合体系结构的多方面因素，采取局部性能指标方案对体系结构的性能进行分析评估，利用最佳性能方法调整构件关系和体系结构性能指标，设计出最优性能的软件体系结构。
