Fuzzy assessment of performance of air transportation transfer system
The transfer system of passenger air transportation as part of the hub airport and the hub-forming airline is considered. The efficiency of the system is characterized by the level of its revenues from the transportation of transfer passengers with an optimally formed timetable. It is assumed that uncomfortable waiting times for a transfer can cause an outflow of passengers potentially ready to be transported through the hub formed by flights of certain airline, while minimizing the damage caused by the outflow of passengers allows optimization of the hub's timetable. The proposed model for assessing the effectiveness of the projected transfer system includes, as a key component, the timetable optimization task, which involves determining such moments of arrival and departure of flights in the hub that maximize revenues from transportation of transfer passengers taking into account capacity constrained of airport production complexes. Uncertainty in the initial data of the model, characteristic for the design stage of the transfer system, is presented in a fuzzy set form. The model can be used to support decision making on the economic efficiency and technical capacity of forming a transfer system based on certain airlines and airports, for solving timetable optimization tasks and creating a balanced fleet of technological resources at the hub airport, rational organization of its industrial complexes, operational resource management. Some examples of application of the proposed model are considered.
