基于B方法的体系结构描述语言的形式化研究

Research on formalism of architecture description language based on B method

通过分析B方法和软件体系结构描述语言ABC/ADL各自的特点,提出了一种两者结合的形式化方法。该方法利用B方法扩充的事件机制,定义软件体系结构描述语言的构件和连接子观察模型、行为规约和约束规约,并给出了规约实例,从而使得基于B方法的ABC/ADL能够形式化描述软件体系结构的结构和行为。

By analyzing the features of B method and software architecture description language ABC/ADL, this paper proposes a formal software method combining B method and ABC/ADL. The method utilizes the extended event mechanism of B method, defines components, connectors, behavior specification, behavior constraints and constraints instances of the Architecture description language ABC/ADL, and then makes the B method based ABC/ADL be able to formally describe the structure and behavior of the software architecture.
