系统图形建模机制及其面向对象设计与实现

Graphical Modeling Framework in PSTSS and its Object-oriented Design and Implement

从过程仿真的基本概念出发，应用面向对象的观点和方法从一个新的角度研究了模型库系统及其设计与实现．主要讨论了过程仿真培训支持系统中最核心的部分——建模机制．从定义过程仿真中的模型入手，讨论了模型与图形建模机制的关系，详细论述了图形建模机制，并给出了其面向对象设计与实现．

Acording to the basic concept of Processing Simulation,the author has conduted researches on the models base system and its design and implement by using the object-oriented method from a new point of view.The contents of this paper are some of the most important parts of the researches,in which the modeling framework,being the heart of PSTSS,is particularly essential.Beginning from the given definition of model,this paper alss discusses the relation between all the models,Processing Simulation and the graphical modeling framework,gives a detailed account of the graphical modeling framework,and presents its design and implement in the object-oriented method.
