大规模定性仿真模型的建立

针对当前已有的定性理论难以分析磊规模系统的缺陷，本文提出一种模型建立理论，对人们常识中的因果关系作了正式的定义，并以之为基础，以明确的仿真目标为指导，给出了系统概念实体识别和模型结构建立方法。

Setting up Large Scale Model for Qualitative Simulation

This article presents a theory of modeling to solve the problem of modeling for large scale systems that exists generally in current qualitative theories. In the article, the causality underlying people,s common sense is formalized , and with the guidance of explicit goal of simulation, the method of system individuals identification is given. The article also gives a method of setting up the structure model of systems. The method automatizes the process of modeling greatly and prepares for further work of model decomposition, model simplifi- cation and local simulation.
