数学模型及其在存货控制中的应用

用数学方法解决实际问题的关键在于将实际问题转化为数学问题,也就是要建立数学模型.本文简要阐述数学模型的概念,建模的方法步骤,并介绍了在存贮控制中两个常用的数学模型.

The key of solving practical problems with mathematical methods lies in how to change practical problems into mathematical problems;——that is to set up mathematical models.The article makes a brief exposition of the concept of mathematical models;the methods of setting up the mathematical models;and presents two usual mathematical models of storage control.
