摘要
在节水灌溉方案优选中,文章采用基于变异系数权重的属性识别模型。该模型采用反映评价指标特征值之间差异性的参数——变异系数作为评价指标的权重,减小了权重确定的主观性,且模型求解方法简单实用。该模型含义明确、计算过程简单,能实现节水灌溉方式的排序,有一定的应用价值。
In the optimization of water saving irrigation modes, this paper adopts an attribute recognition model of comprehensive optimal scheme selection based on the variation coefficient weight. The model uses the parameters-variation coefficient which reflects the eigenvalue difference to represent the weight of the evaluation indexes, thus decreasing the subjectivity of weight determination. The solving method of the model is easy and practical because of its explicit meanings and simple computational process,and the model can produce a rank of the water saving irrigation modes, so it is worth applying in similar optimization.
