层次分析法C#代码

层次分析法AnaliticHierachyProcess(AHP)一、需求分析问题举例在海尔、新飞、容声和雪花四个牌号的电冰箱中选购一种。要考虑品牌的信誉、冰箱的功能、价格和耗电量。在泰山、杭州和承德三处选择一个旅游点。要考虑景点的景色、居住的环境、饮食的特色、交通便利和旅游的费用。在基础研究、应用研究和数学教育中选择一个领域申报科研课题。要考虑成果的贡献（实用价值、科学意义），可行性（难度、周期和经费）和人才培养。模型和方法层次结构模型的构造步骤一：确定层次结构，将决策的目标、考虑的因素（决策准则）和决策对象按它们之间的相互关系分为最高层、中间层和最低层，绘出层次结构图。最高层：决策的目的、要解决的问题。最低层：决策时的备选方案。中间层：考虑的因素、决策的准则。对于相邻的两层，称高层为目标层，低层为因素层。步骤二：通过相互比较，确定下一层各因素对上一层目标的影响的权重，将定性的判断定量化，即构造因素判断矩阵。步骤三：由矩阵的特征值确定判别的一致性；由相应的特征向量表示各因素的影响权重，计算权向量。步骤四：通过综合计算给出最底层（各方案）对最高层（总目标）影响的权重，权重最大的方案即为实现目标的最由选择。因素判断矩阵比较n个因素y=（y1,y2,…,yn）对目标z的影响.采用两两成对比较，用aij表示因素yi与因素yj对目标2的影响程度之比。通常用数字1~9及其倒数作为程度比较的标度，即九级标度法xi/xj相当较重要重要很重要绝对重要aij 1 3 57 92,4,6,8 居于上述两个相邻判断之间。当aij>1时，对目标Z来说xi比xj重要，其数值大小表示重要的程度。同时必有aji=1/aij1，对目标Z来说xj比xi不重要，其数值大小表示不重要的程度。称矩阵A=（aij）为因素判断矩阵。因为aij>0且aji=1/aij故称A=（aij）为正互反矩阵。例.选择旅游景点 2：目标，选择景点y：因素，决策准则y1费用，y2景色，y3居住，y4饮食，y5交通一致性与权向量如果aijajk=aiki,j,k=1,2,…,n，则称正互反矩阵A具有一致

性. 这表明对各个因素所作的两两比较是可传递的。一致性互正反矩阵A=(aij)具有性质：A的每一行(列)均为任意指定行(列)的正数倍数，因此rank(A)=1.A有特征值=n, 其余特征值均为零.则aij记A的对应特征值=n的特征向量为w=(w1w2，…，则aij=wiwj-1如果在目标2中n个因素y=(y1,y2,…,yn)所占比重分别为w=(w1w2，…,wn),则iwi=1,且因素判断矩阵为A=(wiwj-1)。因此，称一致性正互反矩阵A相应于特征值n的归一化特征向量为因素y=(y1,y2,…，yn)对目标z的权向量一致性检验与因素排序定理1:n阶正互反矩阵A是一致性的当且仅当其最大特征值为n.定理2:正互反矩阵具有模最大的正实数特征值1,其重数为1,且相应特征向量为正向量.定义一致性指标为刻画n阶正互反矩阵A=(aij)与一致性接近的程度，定义一致性指标(Consensusindex):CI=(1-n)/(n-1)有满意的一致性。CI=0,A有完全的一致性。CI接近于0,A有满意的一致性。n 12 34 567n 12 34 56789RI 00 0.580.90 1.121.2411.411.45当CR=CI/RI<0.1时，认为A有满意的一致性。wn)为因素.32此时取A的相应于1的归一化特征向量w=(w1w2，…，y=(y1,y2,…，yn)对目标z的权向量。由w=(w2，…，wn)分量wi的大小可以对因素的重要性排序。择校排名二、 使用的知识要点1.动态生成控件三、 主程序界面四、主要程序段动态生本控件，并加上相应所需要的方法:/初始化文本框
