摘要
针对解释结构建模法需要通过求解可达矩阵以实现建模结构化,但可达矩阵的求解比较复杂的情况。证明了对于一类特殊的有向图即有向无环图(DAG),应用解释结构建模法无须求解可达矩阵亦可保证建模结构化的实现。提出了面向DAG的简化解释结构建模法(SISM),并给出其算法。在一定条件下,简化解释结构建模法还可以扩展到全体有向图。以SW移民工程风险分析认知影响图为例,说明了简化解释结构建模法的应用。
Interpretative Structural Modeling method requires calculating the reachability matrix to realize the structural modeling. However the reachability matrix is difficult to get. It is proved that there is no need to calculate the reachability matrix for a Directed Acyelie Graph （DAG）. The Simplified Interpretative Struetural Modeling method （SISM） for the DAG is proposed and an algorithm is presented. Under some conditions, SISM can be extended to the general Directed Graph. An example based on the SISM is given.
