| 中文摘要 | 介绍定性符号有向图(SDG)的建模思想———通过数学模型建立关联矩阵,再转化为图表示,并进行化简。总结了三条化简规则,阐述了如何通过实验,即灵敏度分析来形成关联矩阵的方法。在此基础上总结了定性SDG的建模步骤,并结合65 t/h锅炉系统的典型实例,研究建立其定性SDG模型问题。; Qualitative signed directed graph(SDG) model expresses the cause-effect relations among system variances,which is a significant tool to describe the conjunction relations of large-scale complex systems.The modeling idea is introduced,which is to construct conjunction matrix via mathematical model,then transform it to graph and simplify it.3 rules for simplifying the model are summarized,how to construct conjunction matrix through experimental approach,i.e.sensitivity analysis,is presented.Further,the approach of building qualitative SDG model is summarized,the modeling problem is researched with a typical instance of 65 t/h boiler.; 国家“863”计划项目(2003AA412310) |
