Novel weighted fusion operators and unfusion operators of subjective logic
Hongwei Zhou, Jinhui Yuan, Yawen He · 2016
Our observation shows the limit of subjective logic that it treats equally the opinions and fails to operate them with their weights. To address this problem, we propose four novel operators including cumulative weighted fusion operator, averaging weighted fusion operator, cumulative weighted unfusion operator and cumulative weighted unfusion operator. These novel operators are capable of fusing or unfusing the opinions with their weights in a fair way. Furthermore, we present the justification of the novel operators with the mapping from the evidence space to the opinion space in this paper. At last, we discuss one application of our novel operators as the case study.
