基于MDA的MARTE模型形式化方法

摘要

For the reliability and predictability requirements of embedded systems, this paper proposed MDA-based method to formal describe MARTE, which was a modeling language for embedded systems. It established Object-Z metamodel, and defined model transformation relationship between MARTE metamodel and Object-Z metamodel. It also presented the specific process of semantic mapping and the syntax conversion between MARTE model and Object-Z model. The method supported the formal translation between MARTE model and Object-Z model, it was helpful to test and verify in the early stage of the software development.%针对嵌入式系统对可靠性和可预测性的要求,提出基于MDA对嵌入式系统的建模语言MARTE进行形式化描述的方法.建立Object-Z的元模型,定义了MARTE元模型与Object-Z元模型之间的模型转换关系,给出了MARTE模型到Object-Z模型的语义映射和语法转换的具体过程.该方法支持将MARTE模型形式化转换为Object-Z模型,有利于软件开发早期的检验和验证.
