| 摘 要： | 针对现有单项灌溉水质评价方法评价指标界限刚性量化的缺点,提出了基于熵权的物元可拓综合评价模型,将熵权系数法和物元可拓方法有机结合,不仅解决了灌溉水质单项指标评价结果的不确定性和不相容性问题,而且在确定指标权重时,引入熵权系数概念,克服了传统可拓评价方法在确定评价指标权重时的主观因素的影响。结果表明,该模型的评价结果与属性综合评价法及人工神经网络评价法的评价结果完全一致。从而验证了该模型的合理、简便和实用。

| Abstract: | In view of the uncertainty of indexes for evaluating water quality the entropy value theory is applied to combine with matter-element method to establish an entropy matter-element model.The coefficients of weight in this model are derived from the avail value of data reflecting the information entropy,by this method the problem of weight allocation can be avoided.The calculation result for an example is compared with those by integrated evaluating method and attribute recognition model.It indicates that the... |
