基于AADL的智能交通系统面向方面建模

摘要

为解决智能交通系统(intelligent transport systems,ITS)的传统建模方法中存在难以解决的复杂问题,如不能对横切关注点进行建模、难以分离软件系统的非功能特性等,研究基于体系结构分析与设计语言(architecture analysis and design language,AADL)扩展的面向方面的建模方法在ITS上的应用.基于AADL建立路边单元系统模型,生成系统功能代码,进行流分析测试.基于扩展的AADL描述系统非功能特性,生成方面代码.实例结果表明,该方法弥补了传统建模方法的不足.%To solve problems of traditional modeling methods for intelligent transport systems (ITS),such that they are unable to model the cross cutting concerns and separate the non-functional properties of the software system,an aspect oriented modeling method based on extension of analysis architecture and language (AADL)applied to ITS was researched.Based on AADL,the model of field system was established.System function code was generated.Flow latency analysis and testing was given.Based on extended AADL,the non-functional properties of the system were described.Aspect code was generated.A case study of setup planning was presented.Results verify the method makes up the deficiency of the traditional modeling method.
