Similarity measurement of fuzzy entropies of respiratory sounds and risk measurement according to credibility distributions

In this paper, we have provided some definitions and theorems about fuzzy set, set operations, the uncertainty theory used in environments, credibility which exists on base of mathematical knowledge. Then, definition applications fuzzification, defuzzification, similarity, distribution were included diagnostic medicine. Sounds respiratory patients transferred to computer by recording converted into numerical data. particular, entropies, similarities, credibility.distributions., expected values sounds analyzed using fuzzification defuzzification methods analyze sound data via operations make sense uncertain As increased, changes entropy similarity measures observed. addition, a model for was created numbers supported diagnosis physician. Sound interpreted multipurpose decision methods. Respiratory shown be an indicator diagnosing with model.
