基于类库的化工过程模拟软件的系统设计

Chemical Process Simulation System Design Based on Class Library

化工过程模拟类库包含了模拟计算所需要的基本类 ,它的建立为化工软件资源的重用与共享提供了基础。如何在类库的基础上进行化工过程模拟软件的设计、开发也是体现面向对象思想的重要内容。本文首先设计开发了系统水平上的系统类 ,在此基础上给出了基于类库的化工过程模拟系统的设计方法。本文重点介绍基于类库模拟系统的系统结构 ,特别是众多对象的管理与调度方法。采用容器的方法进行对象管理 ,采用地址的方法进行对象调用 ,以系统类进行系统水平上的调度管理。应用结果表明 ,这种方法使得软件结构清晰合理 ,便于数据共享与功能扩充 ,能够充分发挥和体现面向对象思想在开发大型化工过程模拟系统中的优越性。

A class library for chemical process simulation possesses many elementary classes, which made it possible to develop a object oriented software.But how to design a software structure is another important aspect to realize the advantage of object oriented idea. At first, many classes for system were developed in this paper, owing to them, a method to design a chemical process simulation system based on class library was provided. And emphasis was put on system structure and administrating of objects. Using object containers to administrate objects, and using address of object to call them, made system structure clear, reasonable and flexible. It fully embodied the application of object oriented idea in development of large scale chemical process system.
