摘　　要：针对复杂系统符号定向图(SDG,Signal Directed Graph)定性建模存在的困难,提出一种改进型SDG定性建模方法。通过对目前存在的三种SDG定性建模方法进行比较,阐述了基于功能单元划分的符号定向图(F-SDG,SDG Based on Function Unit)方法起源于基于经验知识的SDG建模法,并对F-SDG建模法的理论基础进行概述;给出F-SDG建模方法的精确数学定义、模型描述图例以及具体建模步骤;以物资供应过程为例,进行F-SDG定性建模过程演示,最后,证实了F-SDG的可行性与实用性。This paper aimed at the occurring difficulty of SDG modeling in studying the complex system, put forward a improved SDG qualitative modeling method. Through comparing three existing SDG modeling methods,it is expatiated that the F-SDG modeling method is from SDG method based on experience knowledge,and summa- rized the theory base of F-SDG modeling method. The rigor math define, the model description legend and the modeling step of F-SDG modeling method is given. Taking the process of material supply as a example, F-SDG qualitative modeling process is demonstrated. Finally,it validates the feasibility and practicability of F-SDG modeling method.
