層次分析法C#代碼

層次分析法AnaliticHierachyProcess(AHP)一、需求分析問題舉例在海爾、新飛、容聲和雪花四個牌號的電冰箱中選購一種。要考慮品牌的信譽(yù)、冰箱的功能、價格和耗電量。在泰山、杭州和承德三處選擇一個旅游點(diǎn)。要考慮景點(diǎn)的景色、居住的環(huán)境、飲食的特色、交通便利和旅游的費(fèi)用。在基礎(chǔ)研究、應(yīng)用研究和數(shù)學(xué)教育中選擇一個領(lǐng)域申報科研課題。要考慮成果的貢獻(xiàn)（實(shí)用價值、科學(xué)意義），可行性（難度、周期和經(jīng)費(fèi)）和人才培養(yǎng)。模型和方法層次結(jié)構(gòu)模型的構(gòu)造步驟一：確定層次結(jié)構(gòu)，將決策的目標(biāo)、考慮的因素（決策準(zhǔn)則）和決策對象按它們之間的相互關(guān)系分為最高層、中間層和最低層，繪出層次結(jié)構(gòu)圖。最高層：決策的目的、要解決的問題。最低層：決策時的備選方案。中間層：考慮的因素、決策的準(zhǔn)則。對于相鄰的兩層，稱高層為目標(biāo)層，低層為因素層。步驟二：通過相互比較，確定下一層各因素對上一層目標(biāo)的影響的權(quán)重，將定性的判斷定量化，即構(gòu)造因素判斷矩陣。步驟三：由矩陣的特征值確定判別的一致性；由相應(yīng)的特征向量表示各因素的影響權(quán)重，計算權(quán)向量。步驟四：通過綜合計算給出最底層（各方案）對最高層（總目標(biāo)）影響的權(quán)重，權(quán)重最大的方案即為實(shí)現(xiàn)目標(biāo)的最由選擇。因素判斷矩陣比較n個因素y=（y1,y2,…,yn）對目標(biāo)z的影響.采用兩兩成對比較，用aij表示因素yi與因素yj對目標(biāo)2的影響程度之比。通常用數(shù)字1~9及其倒數(shù)作為程度比較的標(biāo)度，即九級標(biāo)度法xi/xj相當(dāng)較重要重要很重要絕對重要aij 1 3 57 92,4,6,8 居于上述兩個相鄰判斷之間。當(dāng)aij>1時，對目標(biāo)Z來說xi比xj重要，其數(shù)值大小表示重要的程度。同時必有aji=1/aij1，對目標(biāo)Z來說xj比xi不重要，其數(shù)值大小表示不重要的程度。稱矩陣A=（aij）為因素判斷矩陣。因?yàn)閍ij>0且aji=1/aij故稱A=（aij）為正互反矩陣。例.選擇旅游景點(diǎn) 2：目標(biāo)，選擇景點(diǎn)y：因素，決策準(zhǔn)則y1費(fèi)用，y2景色，y3居住，y4飲食，y5交通一致性與權(quán)向量如果aijajk=aiki,j,k=1,2,…,n，則稱正互反矩陣A具有一致

性. 這表明對各個因素所作的兩兩比較是可傳遞的。一致性互正反矩陣A=(aij)具有性質(zhì)：A的每一行(列)均為任意指定行(列)的正數(shù)倍數(shù)，因此rank(A)=1.A有特征值=n, 其余特征值均為零.則aij記A的對應(yīng)特征值=n的特征向量為w=(w1w2，…，則aij=wiwj-1如果在目標(biāo)2中n個因素y=(y1,y2,…,yn)所占比重分別為w=(w1w2，…,wn),則iwi=1,且因素判斷矩陣為A=(wiwj-1)。因此，稱一致性正互反矩陣A相應(yīng)于特征值n的歸一化特征向量為因素y=(y1,y2,…，yn)對目標(biāo)z的權(quán)向量一致性檢驗(yàn)與因素排序定理1:n階正互反矩陣A是一致性的當(dāng)且僅當(dāng)其最大特征值為n.定理2:正互反矩陣具有模最大的正實(shí)數(shù)特征值1,其重數(shù)為1,且相應(yīng)特征向量為正向量.定義一致性指標(biāo)為刻畫n階正互反矩陣A=(aij)與一致性接近的程度，定義一致性指標(biāo)(Consensusindex):CI=(1-n)/(n-1)有滿意的一致性。CI=0,A有完全的一致性。CI接近于0,A有滿意的一致性。n 12 34 567n 12 34 56789RI 00 0.580.90 1.121.2411.411.45當(dāng)CR=CI/RI<0.1時，認(rèn)為A有滿意的一致性。wn)為因素.32此時取A的相應(yīng)于1的歸一化特征向量w=(w1w2，…，y=(y1,y2,…，yn)對目標(biāo)z的權(quán)向量。由w=(w2，…，wn)分量wi的大小可以對因素的重要性排序。擇校排名二、 使用的知識要點(diǎn)1.動態(tài)生成控件三、 主程序界面四、主要程序段動態(tài)生本控件，并加上相應(yīng)所需要的方法:/初始化文本框
