摘要：
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. © All Rights Reserved.
