I would like to combine the workflow of fuzzy membership and weighted overlay for a suitability analysis and would like to ask if this is "allowed" scientifically.
I have severeal criteria, some would first use Fuzzy Membership to get a membership value from 0-1, some other criteria do not use Fuzzy Membership before (they get a Value from 0-10 through another method).
Then I would standardize the fuzzy value...multiply it with 10, that all criteria have values from 0-10.
After that I wouldn't use "Fuzzy Overlay", but I would use "Weighted Sum" and weight all criteria.
Now my question is: Is this "allowed" to combine Fuzzy membership and Weighted Overlay, or do I have to use "fuzzy overlay" when I work with fuzzy memberships? I would use "Fuzzy Membership" just for the standardization.
