摘要
研究定性仿真建模问题,由于复杂系统结构复杂,包含大量变量和约束,为建立系统的定性仿真模型,需要使用一种结构模型化分析方法来分析系统结构。为提高建模的准确性,以系统物理结构和功能中的因果关系为基础,提出了一种采用结构模型化分析方法辅助建立系统模型的理论。通过对系统要素间的因果关系进行定义,结合仿真目标,对系统要素间的因果关系进行分析,建立了系统的递阶结构模型。结合系统的物理结构与功能特性,建立了定性仿真模型。通过实例说明能快速分析系统要素间的关系,并建立系统的定性仿真模型,为进一步的模型分解与仿真奠定了基础。
For complex system including a large number of variables and constraints,the structure of system is very complex.In order to establish a qualitative simulation model of systems,a structural model analysis method must be used to analyze the system architecture.The theory that utilizes a structural model analysis method to help establish a system model was proposed,which is based on the causal relationship exits in the system physical structure and function.The causal relationship between system elements was defined and analyzed combined the simulation target.Then the hierarchical structure model was established.Finally,the qualitative simulation model was established based on this hierarchical structure model and combined system physical structure and function characteristics.An example illustrates that this method can quickly analyze the relationship between system elements and establish a qualitative simulation model of the system.This method is a foundation for further decomposition and simulation.
