The complex computer-aided system of air transportation cost calculation (“Ecopol”)

 

An air transportation cost-effectiveness calculation is considered to be one of the milestones in airlines commercial activity. Calculation and comparison of the scheduled expenses with expected or actual income is meant to be a concept of the air transportation cost-effectiveness calculation. Economic result assessment profit or damage will be the result of these researches.

The objective of the air traffic operation expenses control is thought to be a reliable assessment of actual flight-connected expenses as well as monitoring the resources and means use. Assessment of exact consumption according to the aircraft types for each particular destination allows airline to improve the tariff and frequency policy and other components of aircrafts commercial operation with lower possible risk. Moreover, polytypic aircraft fleet might be used the most effectively.

The system is designed for the aircraft flights economic justification based on calculation and analysis of air passenger and cargo transportation prime cost for domestic and international airlines.

The system capabilities:

· Flights cost calculation based on different easily modified algorithms;

· Comparative flight computation for different passenger and cargo aircrafts;

· Comparative flight computation for different airline route;

· Air route optimization based on criteria of minimum distance and minimum consumption;

· Air route visualization on the Way Point (WP) level using a map of the world with plotted states borders, ATC zones and regions, airports, and other attributes;

· Dialog mode of formation and update of calculation algorithm for flight cost in the frame of a special purpose math editor;

·  Automatic calculation of airport dues and air navigation tariffs on the route for different states;

·  Fuel filling optimization on an air route with check of limitation for maximum take-off weight, maximum touchdown weight, maximum fuel mass, maximum cargo tonnage, maximum touchdown fuel mass;

· Calculation of the flight profitability in case of specified load and tariff for passengers and cargo transportation. Calculation of air tickets tariffs and cost for transportation of one unit of cargo for different levels of profitability;

·  Calculation of economic characteristics of the flights carried out based on flight assignment data base.

Output documents delivered by the system:

· Flight cost calculation (reduced and complete reports);

· Cartographical information from the selected calculated flights (airlines);

· Report about the flights carried out for an arbitrary period;

· Registers of aircrafts characteristics, air port dues (take-off, landing, parking, passenger, maintenance, unloading and loading works, etc.), air navigation for a territory over flight on the route, business trip and hotel cost for a crew, air routes, WP, ATC zones and regions borders, states, states borders, air ports, states currency courses, international time standard, etc.

    

The main system peculiarities are as follows.

An air route choice and calculations in the system are carried out in the MAP regime based on a map of the world with plotted parallels and meridians in cylindrical or conical projections, borders of states and airports, and other required cartographical information. The map is well within view and easily scaled on a random scale. To start calculations one has to choose a calculation mode and to indicate the airport of departure, intermediate air port and the airport of entry. A reduced flight report is displayed on a screen and filed. One can print the file in DOC or WINDOWS format.

The calculation algorithm correction and the main data assignment of the flight are carried out in the Math Editor regime in the frame of a math editor. The flight date and time, the passengers number in each airport of departure, the stopping time in intermediate airports, food cost for passengers of different classes and a crew, wind speed and direction on the flight route, etc. have to be included into the flight main data base. Data about an air route, the aircrafts characteristics, the airports dues, the fuel cost and other parameters dependent on the chosen route are taken automatically from the correspondent data bases. The calculation algorithms are summed from the operators sequence written in the language which is close to an ordinary math language. The calculation results are displayed on a screen near each operator. The regime is convenient in case of setting and formation of the flight arbitrary calculation algorithms for a certain airline because it has embedded regimes for an editor control (work with blocks, windows, and files) and the system for syntaxes mistakes analysis. This leads to mistakes localization inside the math editor and indicates a false operator.

The formation and correction data about the flights, WP, aircrafts type characteristics, the airports and air navigation dues, states, airports, the fuel cost in air ports, currency exchange courses, the crew subsistence money, etc. are carried out in the Data Base regime. In this regime all the main data base control mode are available: browsing, editing, deletion, retrieving, insertion, sorting, indexing, etc. A quite complete world data base of flight routes that can be easily developed is available in the system. These reference data can be accumulated and further used for calculations.

The automatic input of the currency exchange course and air routes are available in the system. Once calculated and input into the system routes are accumulated and automatically used further in case of repetitive calculations.

More than 40 different flight calculation models and the followed below aircraft types characteristics, data on more than 1000 routes, more than 4000 WP, more than 2200 air ports of more than 150 countries, airports dues and dues for over flight for airports of more than 160 countries, current currency exchange courses of 150 states, etc., have already been input into the system. The following aircrafts types characteristics are available in the system: Il-62, Tu-154, Tu-154, Tu -134, Tu -134, Yak‑ 42, Yak -42D, An-24, An-24RD, Yak-40, An-140-100, An-74-300, An-148, An-38-100, Il-76, An-26, L-410, Il-96-300, F-50, 737-300, B767-300ER, 747-200, B747-300, A-320-100, A310-200, A310-300, A319-100, A319-130, A320-110, A320-210, A320-230, A321-100, A330-200, A330-300, A340-200, A340-300, A340-300E, EMB-120, ERJ-135, ERJ-140, Embaer-170, Embraer-175, DC-8, DC-9, DC-10.
