摘要
目的探讨综合评价中指标权重的确定。方法 以某11个省会城市的大气监测数据为实例,将相似权法应用于属性综合评价系统对该11个城市的大气质量进行聚类和排序。结果 用相似权作为权重得到的评价结果与按Topsis法得到的评价结果基本一致。结论 应用相似权法的属性综合评价既充分利用样本信息又合理体现指标权重,因此评价结果客观合理。
Objective To explore a way of determining the weights of variables in synthetic evaluation. Methods Based on the attribute synthetic evaluation system, similarity weight was used to cluster and rank the atmospheric quality on 11 large cities. Results Realized the classification and ranking for the atmospheric quality of the cities given, the results were almost comparable to that achieved by Topsis evaluation. Conclusion The method of comprehensive assessment using similarity weight in the attribute synthetic evaluation system seemed to be objective and rational. Not only it embodied the weights of variables involved, but also exploiting the information presented by the sample.
