铁路列车调度运行图输出系统中面向对象的软件设计模式

Oriented-objective Software Design Mode in Output System of Train-dispatching Diagram

当前,对于面向对象的软件设计模式是软件工程的重要研究课题之一。而基于铁路知识域的相应研究对于提高铁路系统软件的设计规范和复用性具有重要的意义。本文基于铁路列车调度运行图输出系统的研发基础上,建立了整个系统的面向对象的软件体系结构,同时析取区观察者模式,绘图环境模板模式,代理模式,策略模式四个软件设计模式。

Research on OO software design mode is one of the most important tasks in the area of software engineer now. And the corresponding research based on railway contributes to improving design criterion and re-usability of railway software. According to the experience of R & D of output system of train-dispatching diagram, this article builds oriented-objective structure of software system. At the same time, it puts forward four design modes: OBSERVER, TEMPLATE, PROXY, and STRATEGY.
