I can only speak for myself, but to my way of thinking, fuzzy logic is useful approximate method. Yager R.R., Kreinovich V., August 2000, Technical Report UTEP-CS-00-35, Universal Approximation Theorem for Uninorm-Based Fuzzy System Modelling (http://www.cs.utep.edu/vladik/2000/tr00-35.ps.gz) This method is safe in many applications. I work for Civil Engineering Department. I need tools, which is very reliable. Relation between probability theory and fuzzy logic is unclear. How to calculate reliability of structure with fuzzy and random parameters? (I know many papers about this topic but ...) How to measure the membership function? (I know many papers about this topic but ...) Which t-norm, s-norm we have to apply? The safety of structures has to be clear. Andrzej Pownuk --------------------------------------------- MSc.
