Approximate reasoning algorithm for short term aircraft assignment

The problem considered in this paper is as follows: assign the available aircraft from a fleet to specific routes so that the aircraft are kept in normal operation as long as possible before going to the technical base, taking care that "higher quality" aircraft are assigned to "more important" routes. This paper develops a model for aircraft assignment that includes both numerical and linguistic information normally used by dispatchers. The developed model is tested on a real numerical example.
