[0036] Taking the wine dataset as an example, there are 3 wine varieties, 13 different attributes, and the resulting 45 BBAs are shown in Table 6. We need to identify the source of the sample by providing it and compare it with other methods to draw conclusions.

[0041]Table 2 shows the results of our use of four methods to determine the sample origin. It can be seen from Table 2 that the results caused by the classical D-S evidence theory rules are chaotic, which directly determines that the experimental results are completely b-type. This simple judgment is too absolute and does not consider the impact of high conflict factors on the experimental results. The Yagers method is also not satisfactory. First, it is clear that it focuses too much on mixed results (i.e. m(a,b,c)) to pinpoint the exact origin of the samples. Secondly, the support of the method for the b-type of the vari...
