Fuzzy Preference Domains and Their Use for Selecting an Electronic Flight Bag for Flight Crews

A method for the multicriteria evaluation of alternatives based on preferences specified in fuzzy domains is proposed. The concept of fuzzy scales of the criteria and preference domains is formalized. An algorithm for the fuzzy ranking of alternatives is proposed. A free computer implementation of the fuzzy ranking algorithm is available on the portal ws-dss.com of web services for decision support systems. The capabilities of the ranking procedure based on the preferences specified in fuzzy domains are demonstrated using the important problem of selecting an electronic flight bag (EFB) for flight crews as an example.
