I study fuzzy logic and have an ambiguity. Assume, we have 3 variables: X, Y, Z, where Z = X / Y. To represent the variables we can use fuzzy sets very small, small, medium, big, very big. It's quite a routine to write rules for all the combination (5*5 = 25), so, I'd like to write only direct dependencies, like if X is very big, then Z is very big, if Y is very small, then Z is big.Q: is my understanding correct, and can I use aggregation process to mix those results (using centroid method)?
Aggregate not overlapping fuzzy sets
