主要从优势模糊粗糙集的角度讨论区间有序决策表的模糊近似分布约简。首先,详细分析了区间信息系统中对象间关于准则的赋值优势关系的计算。其次,基于决策类的向上并与向下并的模糊下近似,在区间有序决策表中定义了模糊下近似分布约简。通过引入条件属性的模糊重要度与模糊相对重要度,提出了一种计算模糊近似分布约简的启发式算法。最后,通过实例说明该算法能够得到区间有序决策表的模糊近似分布约简。
The fuzzy approximate distribution reduction of interval ordered decision table is mainly discussed from the perspective of dominant fuzzy sets. First of all, a detailed analysis of the inter-area information system on the criteria for assignment superiority calculation. Second, based on the decision-making class up and down-to-fuzzy approximations, fuzzy approximate distribution reduction is defined in the ordered ordered decision table. By introducing fuzzy importance and fuzzy relative importance of conditional attributes, a heuristic algorithm for computing fuzzy approximate distribution reduction is proposed. Finally, an example is given to show that this algorithm can get the fuzzy approximate distribution reduction of ordered ordered tables.
