【摘要】：在综合评价过程中,Radar图既可以进行可视化定性分析,同时也具有定量分析的能力。针对传统的Radar图综合评价方法进行缺陷分析,并提出三条改进思路:(1)采用Radar图各指标轴之间的夹角大小表示指标的重要程度;(2)简化综合评价函数为特征值分量的几何均值法;(3)采用有序加权的Radar图综合评价方法。改进后的Radar图法评价结果不再受评价者主观取向的影响,评价结果具有唯一性。实例表明Radar图综合评价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.
