组件技术在虚拟试验仿真软件开发平台的应用

针对虚拟试验领域仿真软件可复用性差、维护难度高、开发周期长等缺点，利用组件技术设计并实现了一个仿真软件开发平台。平台基于“框架＋插件”的体系结构，设计了一套完整的组件接口规范和组件间的通信机制，并综合利用了工厂方法、发布订阅、单例、模板等多种设计模式，降低了模块之间耦合性，提高了代码的复用性。使用平台开发的仿真软件具有开发周期短、成本低、扩展性强、易升级维护等特点。

Application of Component Technology in Simulation Software Development Platform within Virtual Test Domains

There are obvious disadvantages with simulation software within virtual test domains, such as difficulty to reuse and maintain,long development periods and so on. A simulation software development platform,based on the techniques of software components, is built to overcome those shortcomings. A whole series of component interface, as well as communication mechanisms between components, are de- signed for the platform. Based on the framework and plug- in architecture, this platform fully utilizes sev- eral software design patterns, such as factory method pattern, publish-subscribe pattern, singleton pattern, template pattern and so on. The simulation software,which are built by that platform, have a lot of merits, such as much shorter development periods, relatively low cost, high scalability and easy to maintain and upgrade, etc.
