Every index factor proportion is taken into account . we also makesome precision analysis 對各項指標(biāo)的貢獻(xiàn)率進(jìn)行分析與計算,并做了精度分析,為科學(xué)選材提供了定量依據(jù)。
The evaluation index factor was calculated to get the comprehensive evaluation value of the platform and the value reflects the product platform capability 確定模型中各個指標(biāo)的評價因子,利用評價因子得到平臺綜合評價值,通過綜合評價值反映平臺的優(yōu)劣程度。
Two indexes was calculated to estimate the best bands union for color combination, one is optimum index factor ( oif, the sum of standard deviation divided by the sum of correlation coefficient . ), the other is the determinant of the co-variance matrix . it can be seen from the result that for color combination the original optimal bands were tm 4, 3, 7 and tm 4, 3, 5, the best mixed images were mnf1, br and ndvi 以協(xié)方差矩陣行列式值和最佳指數(shù)值(組合波段標(biāo)準(zhǔn)差之和除以相關(guān)系數(shù)之和)為評價標(biāo)準(zhǔn),得出對于tm原始波段而言,最佳的彩色合成組合是tm4、3、7和tm4、3、5;綜合幾種變換圖像的彩色合成的最佳組合是mnf1、br、ndvi。
Use the positive result of other countries for reference and analyse present situation of vip of china and take advantage of index factor to establish an evaluating index system of the vip . the system is provided with complex and fuzzy . so a fuzzy comprehensive evaluation model is put forward in the evaluation index system, and the analytic hierarchy process ( ahp ) is used to define the weight of different factors 本文研究了影響風(fēng)險投資項目評價各方面因素的基礎(chǔ)上,結(jié)合國內(nèi)外風(fēng)險投資項目評價體系已有的研究成果和我國風(fēng)險投資發(fā)展的現(xiàn)實狀況,利用指標(biāo)因素法建立了風(fēng)險投資項目評價指標(biāo)體系,針對指標(biāo)體系較為復(fù)雜、評價指標(biāo)具有模糊性的特點,提出了模糊綜合評價模型對其進(jìn)行綜合評價,并引入了層次分析法以確定各指標(biāo)權(quán)重。
Concretely, we separate its products into n series, which composed n strips non-crossed logistics, and then we find m factors that influence the logistics to build eigenvalue matrix of mxn . by the method of entropy weight, we get the weight of the influencing index factors and the value of entropy in each strip and the total entropy of the logistics system 具體來說是把該公司的產(chǎn)品分成n大系列,這n個系列就構(gòu)成了互不交叉的n條物流,找出影響物流的m個因素,建立mn的特征值矩陣,又利用熵權(quán)法求出影響因素指標(biāo)的權(quán)重,求出每條物流的熵值以及整個物流系統(tǒng)的熵,最終求出物流系統(tǒng)的有序度。
