Abstract

UML dynamic models are important for software analysis and design. Verifying UML dynamic models to find design errors earlier is a key issue for ensuring software quality. Because of the characteristics such as concurrency and hierarchy, model checking of UML Statecharts and collaboration diagrams faces the problem of state explosion. In this paper, UML Statecharts is firstly structurally expressed by hierarchical automata and its semantics for open systems is introduced. Then, the synchronization composition of objects in UML collaboration diagrams is expatiated, based on which the global system behaviors can be constructed. Based on hierarchical automata and simulation relation between semantics structures, the compositional rules for verifying concurrent object systems are proposed. It makes possible that the construction of global state space will be unnecessary in model checking of UML collaboration diagrams. The hierarchical structures of UML Statecharts are also brought into the compositional verification, which makes the model checking of implementation models can be carried out through replacing detailed components by abstract specifications.

UML动态模型的组合验证

UML动态模型对于软件分析和设计非常重要。验证UML动态模型以更早地发现设计错误是确保软件质量的关键问题。由于UML Statecharts和协作图的并发性和层次性等特点，模型检查面临着状态爆炸的问题。本文首先用层次自动机对UML状态图进行了结构化表达，并介绍了其在开放系统中的语义。然后，阐述了UML协作图中对象的同步组合，在此基础上构建全局系统行为。基于层次自动机和语义结构之间的仿真关系，提出了并发对象系统验证的组合规则。这使得全局状态空间的构造在UML协作图的模型检查中变得不必要。将UML Statecharts的层次结构引入到组合验证中，使得实现模型的模型检查可以通过用抽象的规范代替详细的组件来进行。
