【摘要】：在綜合評(píng)價(jià)過(guò)程中,Radar圖既可以進(jìn)行可視化定性分析,同時(shí)也具有定量分析的能力。針對(duì)傳統(tǒng)的Radar圖綜合評(píng)價(jià)方法進(jìn)行缺陷分析,并提出三條改進(jìn)思路:(1)采用Radar圖各指標(biāo)軸之間的夾角大小表示指標(biāo)的重要程度;(2)簡(jiǎn)化綜合評(píng)價(jià)函數(shù)為特征值分量的幾何均值法;(3)采用有序加權(quán)的Radar圖綜合評(píng)價(jià)方法。改進(jìn)后的Radar圖法評(píng)價(jià)結(jié)果不再受評(píng)價(jià)者主觀取向的影響,評(píng)價(jià)結(jié)果具有唯一性。實(shí)例表明Radar圖綜合評(píng)價(jià)方法具有可操作性和有效性。
[Abstract]:In the process of comprehensive evaluation, the radar map can be visually analyzed qualitatively and also has the ability of quantitative analysis. The defect analysis of the traditional comprehensive evaluation method of Radar diagram is carried out. Three improved ideas are put forward: (1) the degree of importance of the index is expressed by the size of the angle between the axes of the Radar diagram) the geometric mean method which simplifies the comprehensive evaluation function as the eigenvalue component is used to adopt the ordered weighted comprehensive evaluation square of the Radar diagram. The evaluation results of the improved Radar diagram method are no longer affected by the subjective orientation of the evaluators. The evaluation result is unique. The example shows that the comprehensive evaluation method of Radar diagram is operable and effective.
