| 摘 要： | 在数字地图产品的模糊综合评价中,各评价因素的权重常根据专家经验给定的,这样具有相当程度的主观性,给评价结果的可靠性带来影响.采用熵值与专家经验综合定权的方法,利用升岭形分布确定隶属函数的方法对某DLG产品质量进行了模糊综合评价.通过实例的对比分析,所提方法不仅克服了以往的经验确定权重人为因素的影响,而且减少了基于熵权法...

| Abstract: | The weight of every evaluation factor is always identified by expert’s experience in the field of fuzzy synthetic evaluation for DLG products,because of a certain level of subjectivity,it will have an affect on the reliability of the evaluation results.The paper adopt a synthetic weighting method of entropy weight and the expert’s experience,and make a fuzzy synthetic evaluation of a kind of DLG product quality by the method which subordinate function is determined by liters ridge distribution.After analysis of the example,not only can the proposed method overcome the influence of artificial factors determined by the former experience,but also can reduce the influence of large difference between facts and data relationship which index weight is totally determined by entropy weighting method.The evaluation result is more reliable. |
