摘　　要：加权模糊逻辑的真值传播计算方法是应用加权模糊逻辑的关键 .本文将文献 [6]中提出的不确定性真值传播计算方法推广到加权模糊逻辑 ,给出加权模糊逻辑真值传播的计算方法 ,证明了所给方式满足的性质并对其合理性进行了说明 .文中所用方法描述了不确定问题求解领域中普遍存在的“加权逻辑与”和“加权逻辑或”的模糊逻辑关系 .The method to compute truth\|value propagation in weighted fuzzy logic is a key step to apply weight fuzzy logic. In this paper, a method to compute truth\|value propagation in fuzzy logic reasoning is extended to weighted fuzzy logic. Truth\|value propagation formulas in weighted fuzzy logic are given, their properties are proved and their reasonableness is stated. This method describes the fuzzy logic relationships among 'Weighted Logic And, Or' which generally exist in the field of uncertainty problem solving. A simple example is given to show the method proposed is superior to the exist method.
