一、数学模型概念及类型1.数学模型概念数学模型是对于现实世界的一个特定对象,一个特定目的,根据特有的内在规律,做出一些必要的假设,运用适当的数学工具,得到一个数学结构.简单地说:就是系统的某种特征的本质的数学表达式(或是用数学术语对部分现实世界的描述),即用数学式子(如函数、图形、代数方程、微分方程、积分方程、差分方程等)来描述(表述、模拟)所研究的客观对象或系统在某一方面的存在规律.
First, the concept and type of mathematical model 1. Mathematical model concept Mathematical model is a specific object of the real world, a specific purpose, according to the inherent inherent law, make some necessary assumptions, the use of appropriate mathematical tools to get a mathematical structure To put it in simple terms: the mathematical expression of the nature of a system (or a mathematical description of a part of the real world) of mathematics, that is, mathematical expressions (such as functions, graphs, algebraic equations, differential equations, integral equations , Difference equations, etc.) to describe (describe, simulate) the existence of an objective object or system in a certain way.
