证据合成 冲突证据 有效性 识别一致性
證據閤成 遲突證據 有效性 識彆一緻性
증거합성 충돌증거 유효성 식별일치성
evidence combination; conflicting evidence; effectiveness; recognition consistency
基于证据“可信度”和“确定性”,定义了证据“有效性”,提出了区分证据重要性的新方法,修正了原始证据模型;界定了焦元“有效信度容量”和“识别一致性”,阐明了分配证据冲突的依据,构建了分配系数计算公式,修改了证据合成规则.对比实验表明:改进的证据合成方法在处理高度冲突证据合成时,具有更好的收敛性和鲁棒性.
基于證據“可信度”和“確定性”,定義瞭證據“有效性”,提齣瞭區分證據重要性的新方法,脩正瞭原始證據模型;界定瞭焦元“有效信度容量”和“識彆一緻性”,闡明瞭分配證據遲突的依據,構建瞭分配繫數計算公式,脩改瞭證據閤成規則.對比實驗錶明:改進的證據閤成方法在處理高度遲突證據閤成時,具有更好的收斂性和魯棒性.

Based on the reliability and certainty of evidences, this paper defined the ettec~lveness oi evi- dences, proposed a new approach of distinguishing the evidences importance, revised the original evidences model. Meanwhile, this paper defined the effective reliability capacity and recognition consistency of focal elements, clarified the rule of allocating the evidences conflict, constructed the calculation formula of the allocation coefficient, modified the evidences combination rule. The comparing experiment demonstrates that the proposed evidences combination approach with the combination of highly conflicting evidences has better astringency and robustness when dealing
