Kevin抛砖引玉之“如何验证模型的有效性”

看到8楼的回答，想到了flexterm用户手册中的内容。
在FlexTerm Modeling Paradigm中有这么一段话：
A simulation is defined as, "a purposeful and often radical abstraction of a real life system which can be used to answer questions or solve problems. It contains only those elements of reality that are needed to answer the question or solve the problem." FlexTerm supports this ability by allowing you to define just those elements of a container terminal that are necessary to answer your question while everything else is abstracted. This means that the details of the abstracted portion are ignored or hidden from the model so the modeler can focus on the essential portions.
简单的说是，根据客户想要解决什么问题，就往哪个方向建模。
