The compositional rulc of inference is IZadeh, 1973] as follows: Rule: If U is A then V is B Fact: U is A Conclusion: V is B where the conclusion expression is the composition operation: B'(y) = A'(x)-R(x, y) Here, R(x. y) is the chosen translation of the fuzzy implication. The composition operation is defined as B'(y)=A'(x)R(x,y)= sup min {A'(x), Rx,y)} (7.8) The compositional rulc of inference is IZadeh, 1973] as follows: Rule: If U is A then V is B Fact: U is A Conclusion: V is B where the conclusion expression is the composition operation: B'(y) = A'(x)-R(x, y) Here, R(x. y) is the chosen translation of the fuzzy implication.
