“…An open issue is how to model and handle such kinds of uncertain information. To address this issue, a variety of theoretical methods has been exploited for multi-sensor data fusion, like the rough sets theory [ 16 , 17 ], fuzzy sets theory [ 18 , 19 , 20 , 21 , 22 ], evidence theory [ 23 , 24 , 25 ], Z numbers [ 26 , 27 ], and D numbers theory [ 28 , 29 , 30 ], evidential reasoning [ 31 , 32 , 33 , 34 ], and so on [ 35 , 36 , 37 , 38 ].…”
