Model transformation is one of the most important parts of MDA,therefore,the research of the approach of model transformation is very important. To promote the development of the theory of MDA framework and explore the more effective model transformation mechanism, it does a more in-depth research for the approach of model transformation. Introduce the classification of finite state machine and the work principle of it, and use the theory of finite state machine to the model transformation, thus put forward the model transformation approaches based on finite state machine. Analyse and research the model transformation approaches based on finite state machine from the following several aspects in-depth,mainly including the definition of transformation metamodel,the finite state machine description at the model transformation and the state generation algorithm of enabled reverse operation. The approach in this paper for the model of a more obvious change status transformation between them provides a more convenient model transformation plan, at the same time for the other approach of model transformation has some reference value.%模型转换是MDA框架中最重要的组成部分之一,因此,对模型转换方法的研究非常重要.为了促进MDA框架理论的发展以及探索更有效的模型转换机制,文中对模型转换方法做了较深入的研究.文中通过对有限状态机的分类和有限状态机的工作原理的介绍,并把有限状态机的理论应用到模型转换中,从而提出了基于有限状态机的模型转换方法.文中从以下几个方面对基于有限状态机的模型转换方法进行了较深入的分析与研究,主要包括转换元模型的定义、模型转换中的有限状态机的描述和可逆向操作的状态生成算法.文中提出的方法为有着比较明显的状态变化的模型之间的相互转换提供了一种比较方便的模型转换实施方案,同时对其它模型转换方法也有一定的参考价值.
