以粗隶属函数为工具,给出一种粗集间相似度量的数值算式,并将粗集间的相似度量应用于一类决策条件与结论的匹配问题上。最后通过一个实际例子说明这种方法的合理性。
With the rough membership function as a tool, a numerical formula for the similarity measure between rough sets is given, and the similarity measure between rough sets is applied to the match between a type of decision conditions and conclusions. Finally, a practical example illustrates the rationality of this method.
