说明：  层次分析法是对一些较复杂、较模糊的问题作出决策的简易方法，它特别适用于那些难于完全定量分析的问题。 层次分析法是一种将决策者对复杂系统的决策思维过程模型化、数量化的过程。应用这种方法，决策者通过将复杂问题分解为若干层次和若干因素，在各因素之间进行简单的比较和计算，就可以得出不同方案的权重，为最佳方案的选择提供依据，因此层次分析法常应用分析评价定性量化问题。(Analytic Hierarchy Process is an easy way for some of the more complex, the more obscure the issue of decision-making, it is particularly difficult for those who complete quantitative analysis of the problem. Analytic Hierarchy Process is a method of decision-makers of complex systems thinking process modeling, quantitative process. Application of this method, decision makers through the complex problem into several levels and a number of factors, among the factors that make simple comparisons and calculations, different scenarios can be drawn on the right weight, provide the basis for selecting the best solution, so Analytic Hierarchy Process is often used to quantify the problem of qualitative analysis and uation.)
