介绍了面向对象建模技术,运用面向对象方法对城市轨道交通网络系统进行类的识别与定义,对城市轨道交通网络系统中类的关联、继承及聚集等关系进行分析,在此基础上分析了城市轨道交通网络系统中对象间交互关系,明确了交互行为.最后实现了面向对象的城市轨道交通网络系统的对象建模、动态建模和功能建模.
Introduced the object-oriented modeling technology, the use of object-oriented method of urban rail transit network system identification and definition of class, the urban rail transit network system in the class association, inheritance and aggregation and other relations were analyzed, based on this analysis The interactive relationship between objects in the urban rail transit network system is clarified and the interaction behavior is clarified.At last, object-oriented urban rail transit network system’s object modeling, dynamic modeling and function modeling are realized.
