摘要
针对专家评分法对较小分数差异对象的评价结果存在较大误差,提出了一种模糊灰色综合评价方法。该方法的实质是通过灰色隶属度算子U的作用,放大系统内各种信息的差异,并使相似信息得到压缩,同时,根据类别之间的隶属度信息确定类别权系数。应用结果表明,模糊灰色综合评价方法和专家评分方法相比更符合实际情况。
Aimed at the big difference in the evaluation result of expert grade, one kind of synthetical evaluation method of grey - fuzzy is put forward. The essential of the method magnifies the information difference of system by gray subjection degree arithmetic operatos U, compresses the resemble information, and ascertains regimentation fight coefficient according to subjection degree information at the same time. The result shows the synthetical evaluation method of grey - fuzzy more accords with the practical situation compared with expert grade.
