因果关系图系统基模计算方法及其应用

Causality Graph Systems Archetypes Calculation Method and Its Application

因果关系图系统基模分析技术是管理问题动态性复杂分析的一个重要工具,掌握因果关系图中所包含的系统基模具有十分重要的意义。而目前通过因果关系图系统基模分析技术研究问题的实践过程不够严谨,一是所描述的基模并没有作严格的定义;二是只通过观察来判断因果关系图中所含的系统基模。本文通过构造与因果关系图一一对应的关联数字矩阵,用数字矩阵形式刻画因果关系图中各变量之间的因果链,再对三类常用的系统基模进行了严格的定义,然后通过对数字矩阵采用逐步缩小法和稀疏矩阵优化计算法计算出因果关系图的所有反馈环及反馈环特征,最终通过反馈环特征计算得出因果关系图三类常用的系统基模并给出算例。

It＇s an In order to manage the complex and dynamic analysis of the problcm,the causality graph systems archetypes analysis is an important tool.To grasp the causality graph contained in the system is very important.At present,through the causality graph systems archetypes analysis research questions the practice of the process is not precise enough,first described in the base model,and there is no strict definition;second only to determine the cause and effect relationships by observing the diagram contained in the systems archetypes.In this paper,structure and causality diagram associated with the one correspondence of the matrix,with digital matrix form diagram depicts the relationship between cause and effect chain of causation between the variables,and then on the three types of commonly used systems archetypes for a strict definition,and then right gradually narrow the digital matrix using sparse matrix optimization method and calculation method to calculate the relationship between cause and effect diagram of all feedback loops and feedback loop characteristics,the ultimate feedback loop through the features of the relationship between cause and effect diagram is calculated three commonly used systems archetypes and gives examples.
