Abstract:

The objective of optimization model is to minimize the airlines'fuel cost. Several factors are considered to confirm the optimal composition of airplane types and fleets and to achieve fuel conservation,such as flight frequency on each air route,traffic demand of certain airplane type,route restrictions with the airplane types and the available time of fleet. One mathematical programming model is introduced;meanwhile,the analysis and evaluation of the model applications are presented with example.

Key words: flight optimization, fuel conservation, integral programming
