An Improvement Radar Chart Evaluation Method Based on Sorting Vector Method

为解决传统雷达图中指标权重设计不合理的问题,提出一种基于排序向量法改进雷达图的评估方法。提出基于排序向量法的指标权重计算方法,解决因指标归一化导致权重计算不合理的问题。根据上述得到的指标权重,绘制得到改进的雷达图,并通过计算指标的扇形面积和弧长来反映系统的效能和指标的均衡程度。通过加权和法和加权积法建立了改进雷图的评价模型。实例表明,所提评估方法合理可行。该研究能够进一步拓展雷达图法的应用领域,为系统评价理论与方法提供一种科学可行的技术手段。

To solve the problem of unreasonable design of index weight in the traditional radar chart,an improved radar chart evaluation method based on sorting vector method is proposed.Firstly,an index weight calculation method based on sorting vector method is proposed to solve the problem of unreasonable weight calculation caused by index normalization.Then,according to the index weight obtained above,the improved radar chart is drawn,and the sector area and arc length of the index are calculated to reflect the efficiency of the system and the balance degree of the index.Finally,the evaluation model of improved radar chart is established by weighted sum method and weighted integrated method.The example shows that the proposed evaluation method is reasonable and feasible.The research work can further expand the application field of radar chart method,and can provide a scientific and feasible technical means for system evaluation theory and method.
