针对传统的雷达图评价方法中特征向量面积和周长与评价指标的排序密切关联,造成评价结果的不确定性的问题,作者提出了改进雷达图评价方法.通过提取依赖于扇形图形的特征向量面积和周长,并构造评价向量和评价函数进行定量的综合评价,使评价结果具有唯一性,并通过算例验证了改进方法的有效性.

英文摘要：

Aiming at the problem of evaluation result uncertainty,which is caused by the fact that the characteristic vector of the traditional radar chart is closely related to the sequence of indices,this paper presents a new radar chart evaluation method.Unlike the traditional radar chart evaluation,the components（area and perimeter） of characteristic vector are extracted based on the calculation of fan section.Then the evaluation vector and evaluation function are constructed using the calculated characteristic vector to make a comprehensive evaluation.The evaluation of instances shows that the improved radar chart method is effective and the result is uniqueness.
