基于模型的系统工程设计方法在TCAS中的应用

摘要

In order to solve the problems and defects of the conventional design in TCAS based on the depictions of documents, application of the model-based system engineering design method to TCAS was studied. This method used standard system modeling language SysML. By utilizing multi-views, described and analyzed the requirements of system, and veriifed the requirements through executing the model. The whole design process is requirement-based, testable and traceable, and realizes the transformation from experience design to requirements design.%针对传统空中交通防撞系统（TCAS）设计中基于文档描述的不足，采用基于模型的系统工程方法进行TCAS系统建模。在建模过程中使用SysML语言，通过多个视图来描述和分析系统需求，并通过模型的执行尽早验证需求。整个设计过程都是基于需求的，是可测试、可追溯的，是由经验研发向需求研发的转变。
