摘要/Abstract

摘要： 三支决策粗糙集模型进行决策时，往往将数据集中在一个信息表中，从整体角度分析客观事物并对其进行决策。然而在多人决策这种情况中，不同的人由于其自身知识不同会对同一事物做出不同的决策，这体现了局部性认识与决策过程。为了能从整体和局部认识事物并做出合理的最终决策，提出了基于-粗糙集的三支决策模型，并给出了一个疑难杂症的医疗诊断过程中具体应用该模型的例子。

Abstract: When using the method of three-way decision, we will put all data into an information table, and analyze objective entities from a single perspective. However, in a case of multi-persondecision, different people will make different decisions to the same object according to their own knowledge, which reflects partial cognition and decision. This paper puts forward a model of three-way decision based on -rough sets to make a reasonable decision for an object from both whole and partial cognition. An example about a decision-making process of rare illness is given to explain the model in the last part
