仿真模型的可重用性研究

针对目前建模与仿真的现状和特点，分析了解决仿真模型重用的关键技术－面向对象的分析与设计方法的基本原则和重要作用。指出了面向对象技术中的抽象、信息隐藏、多态和继承等基本原则是隐藏复杂性、提高代码重用性和标准化的基础。进一步给出了模型重用的分类和前提，并重点论证了模型分类、公有属性提取、结构与参数分离、数据与处理方法的封装和ＶＶ＆Ａ技术是实现仿真模型可重用性的技术步骤。

Research on Model Reusability in Simulation

Depending on the development situation of simulation & modeling, the key technology, which solves the reusability of simulation & modeling , is discussed. The essential principles of object oriented analysis and design method including conception abstract, information hiding, polymorphism and inheritance, which is the foundation of hiding the complexity, promoting the reusability and standardization of code, are analyzed. Furthermore, the catalog of model reusability and precondition of obtaining model reusability are given. Finally the technical approaches of obtaining modal reusability such as model categorization, public property summarization, isolation of parameter and structure, encapsulation of date and operation, VV&A are discussed.
