摘　　要：符号有向图(Signed Directed Graph,SDG)是一种定性描述过程系统故障与故障源之间因果关系的模型方法。对SDG的研究进展进行了全面总结,通过实例介绍了SDG定性模型,重点介绍了SDG半定量模型以及SDG在安全评价中的研究成果,最后对未来发展趋势进行了展望。Signed directed graph （SDG） is a modeling measure for qualitative description of causality between fault and fault source of the process systems. A summarization about SDG was researched and SDG qualitative model was introduced with a sample. Semi-quantitative model and research results in hazard assessment were especially introduced. Finally, the future of development direction of SDG was pointed out.
