系统工程的建模问题

摘要

建立系统模型解决实际问题是系统工程的重要研究课题之一，模型的可行性必须要有正确的理论依据和严密的推理过程来支持。本文介绍了一般的建模思路和建模应注意的问题，并通过分析一个实例的3种建模方法从正反两方面进行说明。%Establishing system model to solve practical problems is one of the important research tasks of the systems engineering. The feasibility of the model must be supported by correct theory foundation and rigorous reasoning. This article analyses three modeling methods for an example, then introduces normal thinking and noticed problems of modeling in correct and wrong view.
