Reliability of combat aircraft: Incompletely structured problems and possibilities for their solution

Abstract

In the article are considered the incompletely structured problems emerging in the field of reliability of combat aircraft (fighter-bombers) in execution of given missions, and a manner of their solution is proposed. With respect to the reliability of the aircraft systems three characteristic cases have been analyzed: maximum range, maximum reliability in execution of mission, combat mission with utilization of armament. Insufficiently structured problems are outlined, and possible courses for their solutions are suggested. One of the possible solutions encompasses the division of the combat aircraft to systems vital for the flight security and systems vital for execution of mission. In the definition of significance of individual flight security systems the fuzzy logic is applied, rules of approximate reasoning are established, dephasing is worked out, and change of reliability parameters is suggested.
