中文摘要：

为了满足软件体系结构复杂性的预测和评价需求，通过抽取构件之间的连接，提出了基于复合关系的分层式软件体系结构，从而能够清晰、准确地表达构件之间的关系。在该结构基础上，提出了基于加权图的复杂性评价模型，并结合实例分析了模型的使用效果。模型能够准确地刻画系统结构及构件关系，而且能够较为客观地定量评估系统结构复杂性。它具有实现过程简单、通用性强等特点。

英文摘要：

In order to satisfy the requirements of predicting and evaluating complexity of software architecture, this paper presented composite relationships based and layered software architecture, which could exhibit the relationships between components explicitly and accurately, through the separate links between components. Based on the software architecture, pro- posed weighted graph based evaluation model for complexity, with an example to be analyzed and explained how to use the model. Moreover, the experiment indicates that the software architecture can reflect real structure and the evaluation model can quantitate complexity of software architecture. Finally, it can be concluded that the model owned the characteristics such as simplicity to process, strong universality.
