摘　　要：使用类型化的属性图及其图文法来直观而形式地刻画软件体系结构和体系结构风格,用图转换来刻画动态体系结构的重配置行为.基于这种刻画,构建了一个动态软件体系结构支撑环境.该环境一方面,通过一个基于图文法的编辑器来支持体系结构图模型的可视化构造和操纵;另一方面,基于内置运行时体系结构技术实现了体系结构图模型在具体系统中的物理实施,并使得图模型上的图转换操作可以自动映射到实际系统的动态重配置上.再加上一系列的辅助设施,形成了一个较为完整的基于图文法的动态软件体系结构支撑环境.In this paper, software architectures and architecture styles are modeled with attributed typed graphs and graph grammars respectively. Accordingly, dynamic reconfigurations of software architectures are modeled with graph transformations. Based on such a modeling, a supporting environment is constructed twofold. Firstly, the visual manipulation of the graphical representation of software architectures is supported with a graph grammarenabled editor. Secondly, the graphical architecture model is reified as a runtime software architecture object built into the physical running system, through which graph transformations of the architecture model is then naturally reflected as dynamic reconfigurations of the running system.
