“…Knowledge representation and uncertainty measure are important issues in artificial intelligence [14,27,7,57,31]. A lot of methods have been presented, including intuitionistic fuzzy sets [16], Z-number [19], evidence theory [38], D numbers [25], evidential reasoning [58,24], complex evidence theory [45,46,47], which are applied in classification [28,52,23], information fusion [48,22], medical diagnosis [3,43], fault diagnosis [50], intrusion detection [32], reliability analysis [32], risk analysis and assessment [34,56,33,44,20], and decision making [42,11,12,8].…”
