Multiattribute Aircraft Choice for Airline Network

Abstract

Multiattribute decision-making methods were used to solve the problem of choosing aircraft size and the corresponding network composition. Prior to ranking, a model was developed to calculate flight frequencies offered to passengers according to available capacities at the highest possible level of service. Flight frequencies thus obtained were used as input data for the calculation of parameters on which the ranking was based. Aircraft of different capacities were ranked based on the following criteria: investments in fleet, average operating costs per passenger carried, percentage of airline services with one flight daily, average schedule delay per passenger, and the number of aircraft in the fleet. The considered alternatives were ranked using the permutational method taking into account only the order of importance of the previously mentioned criteria.
