Оптимізація транспортних потоків при організації міжнародних авіаційних перевезень

Abstract

Розроблено транспортну модель оптимізації плану міжнародних авіаційних перевезень, яка дозволяє раціонально розподіляти повітряні судна авіакомпанії за повітряними лініями. Реалізована у табличному процесорі MS Excel транспортна модель забезпечує мінімальну вартість виконання міжнародних авіаційних перевезень при існуючому попиті на авіаперевезення та обмеженій пасажиромісткості повітряного парку. When opening new international routes or changing demand for existing international air travel routes, airlines face the problem of redistributing transportation flows to minimize costs and increase competitiveness in the aviation market by reducing the cost of flights. The mathematical apparatus used to optimize transportation is based on linear programming models, in particular, their special class – the transport model. In carrying out the research, scientists focus on the optimal organization of passenger and cargo flows for maximum satisfaction of the demand for transportation, but do not take into account the complex assessment of passenger capacity and the cost of transportation by different types of aircrafts. The purpose of the research is to optimize transportation flows in the organization of international air transportation using a transport model in the MS Excel software by rationally distributing aircrafts on international air routes, taking into account the demand for transportation, the composition of the air fleet of the airline, its passenger capacity and the cost of the flight on a certain route. In the article the formalization of the problem of optimization of transportation flows in the organization of international air transportation in the form of a transport table is presented. An example of optimization of transportation flows in the organization of international air

transportation of the average Ukrainian airline, which has aircraft types B-737-200, B-737-300, B- 737-400, B-737-500 and performs flights on routes Kyiv-Athens, Kyiv-Ashgabat, Kyiv-Budapest,

Kyiv-Warsaw. The calculations take into account the passenger capacity of each type of aircraft in the provision of economy class services, the cost of the flight and the demand for transportation. The calculations carried out in the MS Excel software confirmed that to improve the organization of international air transportation it is advisable to use the proposed transport model, which allows to find the optimal distribution of aircraft on selected routes with a minimum cost of transportation, subject to the imposed restrictions on the volume of passenger traffic, the number and passenger capacity of the aircraft available. In the future, it is appropriate to consider the inverse problem: calculating the airline’s need for the number of aircraft of each type, taking into account the demand for air transportation.
