. We use deficit functions (DF) to decompose an aviation schedule of aircraft flights into aircraft chains (routes) called … circulating along the airports of this set. The initial step in our approach is to find the minimal number of aircraft needed to … carry out the flight schedule. This is achieved by using the fleet size theorem based on a DF representation of an aircraft …

To keep load factors high while offering high frequency service, airlines tend to reduce the size of the aircraft they … congestion and delays are growing. Furthermore, demand for air transport is predicted to continue growing but aircraft size is … not. This paper aims to investigate and explain this phenomenon, the choice of relatively small aircraft. It seems that …
