AHP层次分析法，matlab实现。层次分析法是将决策问题按总目标、各层子目标、评价准则直至具体的备投方案的顺序分解为不同的层次结构，然后得用求解判断矩阵特征向量的办法，求得每一层次的各元素对上一层次某元素的优先权重，最后再加权和的方法递阶归并各备择方案对总目标的最终权重，此最终权重最大者即为最优方案。(AHP analytic hierarchy process (AHP) and MATLAB implementation. AHP is a decision problem according to the general goal and sub goals, evaluation criteria of specific investment plans until the preparation of sequential decomposition into different hierarchy, then the judgment matrix eigenvector method is used to solve the weight of each element, the priority of each level to a level of an element, the recursive method and then merge the preparation of the final weight weighted alternatives to the overall goal, the ultimate maximum weight is the optimal solution. Here the so-called "priority" is a relative measure, it shows that the preparation of evaluation criteria or sub goal selection scheme in a relative measure of superior characteristics, degree of scale, and each sub goal for a relative measure of the)
