摘要
将可拓评价基本方法与“三分而治”决策思想融合,引入序贯思想,构建可拓序贯三支决策模型,实现动态决策与挖掘优化指标的目的。首先,对数据进行标准化处理,计算属性的权重;其次,将可拓评价方法作为三支决策的评价准则,定义新的决策规则,阐释划分3个域的合理性;然后,根据属性权重得到多个粒度的序贯评价属性,进行多阶段三支决策,给出决策结果;最后,根据决策结果对引起样本划分变化的指标进行分析,并提出优化建议。将模型应用于水资源承载力分析领域,与熵权物元可拓决策模型进行对比。结果表明,运用可拓序贯三支决策模型与熵权物元可拓决策模型所得的评价结果基本一致,准确率达84.55%,验证了模型的有效性和实用性。
The basic method of extension evaluation and the"rule by three divisions"decision-making idea are integrated,and the sequential idea is introduced to construct an extension sequential three-way decision model and realize the purpose of dynamic decision-making and mining optimization indicators.Firstly,the data is standardized and the weight of attributes is calculated.The extension evaluation method is used as the evaluation criterion of the three-way decisions,new decision rules are defined,and the rationality of dividing the three domains is explained.Then,according to the attribute weight,the sequential evaluation attributes of multiple granularity are obtained,the multi-stage three-way decision is made,and the decision results are given.Finally,according to the decision-making results,the indicators that cause changes in sample division are analyzed,and optimization suggestions are put forward.The model was applied to the analysis of water resources carrying capacity,and compared with the entropy weight matter-element extension decision-making model.The results show that the evaluation results obtained by using the extension sequential three-way decision model and the entropy weight matter-element extension decision-making model are basically consistent,the accuracy rate reaches 84.55%,which verifies the validity and practicability of the model.
