熵权属性识别模型综合评价灌溉管理模式
|
摘要
针对节水灌溉运行管理模式在优选过程中,各方案中指标的多属性特征,采用熵值法赋权与属性识别理论相结合,建立了熵权属性识别运行管理模式综合评价模型,通过计算各指标属性测度、灰色接近度和评分准则进行排序分析,选出最适宜模式。熵值赋权可减小因主观因素带来的误差,属性识别有效判别指标值属性测度,灰色接近度的计算从客观的角度判断了管理模式的等级。该模型评价思路清晰、便于计算,可为管理者在选用灌溉管理模式方面提供技术参考。
Aiming at the problem of multi-attribute characteristics of each scheme index in the optimization process of water saving irrigation operation and management mode,by combining the entropy method with the attribute recognition theory,a comprehensive evaluation model for the operation and management mode based on the entropy weight attribute recognition is established. Entropy weight can reduce the error caused by subjective factors,attribute identification can effectively identify the index value attribute measure,and the calculation of gray proximity can judge the level of management mode from an objective perspective. The model is clear in thinking and easy to calculate,and can provide technical reference for managers in model selection.
