英语翻译In practice,this rule is very rarely verified.The essential characteristic of a multi-attribute problem is that there are several conflicts between attributes and the MMD risks become too poor and useless to aid the DM.Based on the psychological observation that people tend to simplify the multi-attribute complex problem,and to make their decision from a reduced subset of the most important attributes,we suggest the mixed data multi-attribute dominance for a reduced number of attributes MMDR.This dominance can be defined in the same way as the MMD,but should be verified in relation to the subset R of X attributes (seeZaras and Martel,1994).
