摘要 针对 Dubois 模糊粗糙集、Radzikowska 模糊粗糙集、双论域上的模糊粗糙集,分别定义各自对应的模糊信任(似然)函数,证明模糊信任(似然)函数等于其对应的模糊集的下(上)近似质量,据此建立模糊决策表的证据推理模型.实例表明,该模型是行之有效的. Fuzzy belief function and fuzzy plausible function are defined on Dubois fuzzy rough sets, Radzikowska fuzzy rough sets and fuzzy rough sets over two universes respectively. Then the equation relation between fuzzy belief function and lower approximation quality is proved. Thus, a model for evidential reasoning in fuzzy decision table is proposed. An example shows that the model is effective.
