基于三角模糊数的地图质量语言评价研究

Research on Map Quality Linguistic Evaluation Based on Triangle Fuzzy Number

为提高地图质量评价的科学性,减弱由评价者带来的主观不确定性,根据地图质量语言评价模式,将语言评价转化为三角模糊数,再按模糊理论进行地图质量评价,不仅考虑了地图质量的不确定性,而且考虑了地图质量属性的重要性。实例评价结果表明,采用该方法能将定性评价转化为定量评价,评价结果更具客观性和说服力,能为地图质量评价提供参考。

In order to improve the scientificity of map quality evaluation,and reduce uncertainty caused by evaluator,we adopted triangle fuzzy number to evaluate map quality.In this method,the linguistic evaluation was transformed into triangule fuzzy number.The result shows that this method can make qualitative evaluation into quantitative evaluation,and the evaluation results are more persuasiveness.It not only considers the uncertainty of map quality,but also takes into account the importance of map quality attributes.This study can provide a reference method for map quality evaluation.
