摘要

面向对象建模有利于从不同的角度对对象行为进行建模,并在开发过程中对行为模型进行逐次细化。这就产生了行为模型的一致性问题。UML模型的形式化语义的缺失,以及在开发过程中使用行为模型的众多可能性,导致了许多不同一致性概念的兴起。在本文中,我们讨论了UML中行为模型的一致性问题,并提出了如何处理一致性问题的一般方法。根据该方法,将模型中与一致性相关的方面映射到一个语义域,在该语义域中可以制定精确的一致性测试。语义域的选择和一致性条件的定义可以用来构造不同的一致性概念。我们通过给出一个并发面向对象模型的具体一致性问题的示例来展示我们的方法的适用性。

A methodology for specifying and analyzing consistency of object-oriented behavioral models
Object-oriented modeling favors the modeling of object behavior from different viewpoints and the successive refinement of behavioral models in the development process. This gives rise to consistency problems of behavioral models. The absence of a formal semantics for UML models and the numerous possibilities of employing behavioral models within the development process lead to the rise of a number of different consistency notions. In this paper, we discuss the issue of consistency of behavioral models in the UML and present a general methodology how consistency problems can be dealt with. According to the methodology, those aspects of the models relevant to the consistency are mapped to a semantic domain in which precise consistency tests can be formulated. The choice of the semantic domain and the definition of consistency conditions can be used to construct different consistency notions. We show the applicability of our methodology by giving an example of a concrete consistency problem of concurrent object-oriented models.
