约束变量

According to the system view ofdegradation and decomposition put forward above,the paper proposes a newSplit Reasoning Simulation for qualitative model algorithm called SRSQM,which implements the decomposing,reasoning and solving of qualitative models.In another word,it combines variable cluster and causality graph to decompose acomplex qualitative model into many componentsand constraintsamong those components.Through the qualitative reasoning of the componentsand globally propagating the results,the overall solutions can be achieved.

根据复杂系统的递阶分解的系统观点，本文提出一种新的定性模型分解推理仿真算法，称作SRSQM，实现对定性模型的分解推理求解，即对于一个复杂的定性决策模型，应用变量聚类和因果图相结合的方法，将复杂的定性模型分解成若干个单元及其单元之间的约束，通过对各个单元的定性推理以及将单元推理的结果进行全局传播和过滤，得到整个系统的全局解。
