说明：  层次分析法，简称AHP，是指将与决策总是有关的元素分解成目标、准则、方案等层次，在此基础之上进行定性和定量分析的决策方法。该方法是美国运筹学家匹茨堡大学教授萨蒂于20世纪70年代初，在为美国国防部研究"根据各个工业部门对国家福利的贡献大小而进行电力分配"课题时，应用网络系统理论和多目标综合评价方法，提出的一种层次权重决策分析方法。该文件中包含了使用MATLAB来实现层次分析法的代码。
(Analytic hierarchy process (AHP) is a decision-making method that decomposes the elements that are always related to decision-making into objectives, criteria, schemes and other levels, on which qualitative and quantitative analysis are carried out. In the early 1970s, Sarti, a professor of the University of Pittsburgh, an American operational research scientist, applied the network system theory and the multi-objective comprehensive evaluation method to the research of "power distribution according to the contribution of various industrial sectors to the national welfare" for the US Department of defense, and proposed a hierarchical weight decision analysis method. This file contains the code of using MATLAB to realize AHP.)
