基于熵测度的四参数区间数的湖泊水质综合评价
|
摘要
针对湖泊水质影响因素指标值为四参数区间数的不确定性多属性决策问题,提出决策信息为四参数区间数的湖泊水质综合评价的距离熵模型。定义了四参数区间数距离熵测度的算法,利用多指标决策的逼近理想点法,通过计算各方案的正理想解之间的贴近度,根据正理想解之间贴近度的大小对各方案从优到劣进行排序。最后,将建立的距离熵模型应用到湖泊水质的综合评价中,结果体现了决策方法的合理性和可行性。
A distance entropy model for the comprehensive evaluation of lake water quality with the decision-making information of four parameter interval Numbers is proposed.In this paper, an algorithm for distance entropy measurement of four parameter interval Numbers is defined, and the nearness degree between positive and ideal solutions of each scheme is calculated by using the approach of ideal point method of multi-index decision making, and the schemes are sorted from the best to the worst according to the nearness degree between positive and ideal solutions.Finally, the distance entropy model is applied to the comprehensive evaluation of lake water quality, and the results show the rationality and feasibility of the decision-making method.
