摘要

计算机动态建模与仿真中，人们最常用的用以辅助进行交流和讨论以及文档化相关成果与决策的分析、设计方法及表示法是信息流图（information flow diagram）。在前人研究的基础上，提出了一种改进的、更为完善的信息流图表示法。该表示法共包含三大类、九小类组成元素，基本能够完全覆盖计算机动态建模与仿真中所有种类的数学公式及其他模型表达方式。最后，以精馏塔的动态建模与仿真为例，详细说明了改进的信息流图的具体应用情况。事实证明，改进的信息流图不仅为相关工作人员提供了良好的沟通媒介，还使人们能够更加容易地从先前的仿真模型构建项目中复用需求和设计组件等，从而提高了仿真模型构建的效率和质量。

Abstract

While doing an engineering project

engineers always use standard analysis

design methods and notations to assist them to communicate

discuss and document the related results and decisions.In the computer dynamic simulation field

the most frequently used analysis

design method and notation is the information flow diagram.Based on the previous research

an improved

more perfect information flow diagram for modeling and simulation process was presented.Such notation contains three broad categories (variable

directed line segment and boundary) and nine small classes elements

which could completely cover all kinds of mathematical formulas and other model expression ways in the computer dynamic modeling and simulation process.Besides

common combination illustrations and corresponding numerical methods were also been introduced in this paper.And at the end of this paper

dynamic modeling and simulation process of a distillation column is used to illustrate the using process of such improved information flow diagram detailedly.Besides

a large number of applications of such information flow diagram in research issues and engineering projects proves that it could not only provides a perfect communication medium for the simulation related staffs

but also makes people to reuse requirements and design components from the previous simulation project more easily

which could greatly improves the efficiency of the modeling and simulation process and the quality of the simulation model consequently.
