A Method to Compute Truth-value Propagation in Weighted Fuzzy Logic
|
Abstract:
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.
