The invention relates to computer technology, in particular to the optimization of passenger volumes

The decision to increase the profitability of passenger traffic is based on statistical data, which are characterized by the results of the passenger services that are performed during a specified time period, which may be either a calendar year or calendar season.

Statistics typically include the following indicators: the flight number, the name of the route, the number of flights made in each room for a specified period, the income attributable to each flight revenue per passenger-km, average revenue rate for the voyage, for each booking class, full revenue flight for a specified period, the employment rate of the seats on the flight, number of passengers carried (million passenger-kilometers, million Krasnokamenka etc.

Mapping the dynamics of changes in these indicators in their relationship allows a sufficient degree of probability to judge the potential of the exploited market structure of passenger traffic (income rate), about the effectiveness of the schedule (the correct placement of the sun), on the correct application of tariffs, etc.

Optimization of passenger volumes is for modern airline is ne of the aspects of administrative activity.

As a rule, any transportation company operating in a particular market, can be considered as a dynamic system.

In the General case, the input variables of this system are the price (rates, the average ticket price) and the quality of the product transportation.

The output coordinate system is the demand for this product. As can be seen from Fig.6, the control parameters of the system carrier - market rates and traffic volumes. It is these values, the company can accurately monitor.

To formalize the problem statement will use the guaranteed method for statistical estimation of parameters of processes and systems [1].

In accordance with this method, the worst, an unwanted demand functions that minimizes the risk of misinterpretation, is:

where is the price;

V - the volume of traffic in passenger-kilometres (RPK);

a, b - coefficients of the exponent.

In practice, the approximation of the original exponential function and its reduction to linear form (classic view demand functions):

In the sense of the ratio means the solvency of the market (the maximum price that may even passenger to pay); the ratio a/b has the meaning of capacity (capacity) market, see Fig.7.

the service provider b is defined as the ratio of the magnitude of the number of passazhirokilometrov, attributable to a particular flight, number of passengers aboard the aircraft, doing this flight (see[4], s-175), where table 2 shows an example of calculating specific values of the indices a; b to calculate the revenue rate of turnover of passengers on the Moscow - London.

Knowing the demand function, we can calculate the income from the sale of transportation, i.e. revenue:

Operating expenses, which transport company will incur when performing transportation, can be represented as follows:

where p - the cost of which is not dependent on flight;

q - specific costs from the flight.

Then the profit of the airline M from the executed transportation can be defined as:

The challenge in creating such a system optimization of passenger volumes, which would allow to find the optimal profit value M of the airline, taking into account all costs, as independent, and not dependent on the flight.

andbVqp

Numerical values of indicators for each of these accounts are tied to a specific species (groups) flights and interim period for which they received.

To solve the task the operator from his workstation specifies the ID of that time period given group flights for which you want to determine the extremum of the function M=(a-bV)·V-p-qV

ID code time period from the input system 20 is fed to the input of the register 32 of the block 1 is inserted into it a synchronizing signal from the input 23 of the system. From the output of the register 32 ID code time period is decoded by the decoder 33, which on one of its inputs and generates a high potential.

In parallel, the clock pulse from the input 23 of the system is delayed by element 38 at the time of entering code in the register 32 and the operation of the decoder 33. Then, the same impulse arrives at the inputs of elements 34-36 And polling their status.

Given the fact that open decoder 33 to one input of only one of the elements 34-36 And then passing the corresponding element And Synchron the pulse, first, is fed to the input of the reading of the corresponding fixed memory permanent storage device 31. In the fixed cell ROM stores the reference cell address memory of the database server from which the database server stores the data array of the specified calendar period, and reads the base address of the calendar year at the output 41 of the block 1.

Code reference address from the output 41 of the block 1 is supplied to the information input of the register 3, where and are recorded synchronizing pulse from the output 42 of the block 1, the delayed delay element 39 on the time code read from the memory block 31.

Code reference address from the output of the register 3 is supplied to the information input 86 unit 8, where it is fed to one input elements 83 And groups. In parallel, the clock pulse from the output 42 of the block 1 through the inlet 88 unit 8 is supplied to the installation log trigger 81 unit 8 and confirms its original condition in which a high potential with inverted output trigger 81 opens on one of the inputs of the elements 83 And groups.

Address code from the output of the register 3 through the inlet 86 unit 8 is supplied to other input elements 83 And the group passes the elements 84 OR group and is issued for the address output 27 of the system.

In parallel with the described process of forming the read address of the database server synchronization pulse is one output element 39 block 1 is delayed by element 40 during operation of the register 3 and then available at the output 29 of the system as a pulse reading at the input of the first interrupt server.

On this signal, the server goes to the subroutine read-write array data from the database server according to the address generated at the output 27.

The contents of the reference address of the selected memory cell is issued by the database server through the entrance 21 of the system to the information inputs of registers 45-49, where it is recorded synchronizing pulse server, sent from the input 24 of the system.

As a result, in the respective registers will contain the numerical values of the relevant indicators, as shown in the table.

Rooms registersNumerical values of parameters
The register 45factor - a
The register 46factor - b
Register 47traffic volume - V
Register 48costs, depending on the flight, - q
Register 49costs that do not depend on that flight, " p

The multiplier 12 is designed to generate works of bV, and the multiplier 13 for the formation of a work - qV.

To this end, the information inputs of the multiplier 12 outputs 61, 62 unit 2 receives the numerical values of CoE is ficient b and transportation volume V, and information on the inputs of the multiplier 13 outputs 64 and 63 unit 2 receives the numerical values of cost q and traffic volume V.

At clock signal input 24 of the system, passing the element 52 OR block 2 and the detainee element 53 at the time of entry codes in the registers 45-49 coming from the output 65 of the block 2 to the sync inputs of the multipliers 12, 13, calculate the last mentioned works and give their information to the respective inputs of registers 4 and 5.

Entering codes in the registers 4 and 5 is provided by a synchronization pulse from the output element 53, the detainees element 54 during operation of the multipliers and coming from the output 66 of the block 2 to the clock inputs of registers 4 and 5.

The codes of the results obtained from the outputs of registers 4, 5 come to one inputs of the adders 9 and 10, on the other inputs of which are served codes numerical values from outputs of the registers 45 and 49 unit 2 through the outlets 60 and 64, respectively.

The adder 9 is designed for calculating the difference (a-bV), so the numerical value of the product of bV from the output of the register 4 to one input of the adder 9 is fed in the reverse code.

The adder 10 is designed to calculate the sum (p+qV), so the numerical values of both components are received at the inputs of the adder 10 in the direct code.

Synchronization of the operation of the adders 9 and 10 is to synchronise usamu signal, coming from the output of delay element 55 through the output 67 of the block 2 to the sync inputs of the adders 9 and 10.

Resulting code (a-bV) from the output of the adder 9 is supplied to one input of the multiplier 14, the other input of which is applied numerical code of the traffic volume of the output register 47 unit 2 through the outlet 62. By synchronizing the output signal from the delay element 56 flowing through the output 68 of the block 2 to the sync input of the multiplier 14, the multiplier computes the product of (a-bV)·V, code which is supplied to one input of the adder 11.

The adder 11 is designed for calculating the difference

[(a-bV)·V-(p+qV)],

therefore, the numerical value of the sum (p+qV) from the output of the adder 10 to the other input of the adder 11 is supplied in the reverse code. By synchronizing the output signal from the delay element 57 is supplied through the output 69 of the block 2 to the sync input of the adder 11, the output of the adder 11 is formed numeric value profit margins M, which is given on the information output 28 of the system.

Simultaneously, the clock pulse from the output 69 of unit 2 through the inlet 78 unit 7 is fed to the inputs of the elements 72, 73 And. Given that to this point in time, the trigger 71 is in the initial state, a high potential with inverted output element 73 will be opened and the element 72 And the closed low potential direct you the ode.

As a result of this input pulse passes through the element 73 And the input of the read memory block 70, made in the form of a persistent storage device in a fixed memory location which stores the base address from which database server to generate a dataset generated at the output 28 of the system.

As a result of reading the base address output 79 unit 7 is supplied to the information input of the counter 6, where he entered a synchronizing pulse from the output element 73 And detained element 75 on the time code read from the ROM 40, and output 80 unit 7 received at the clock input of counter 6.

From the output of the counter 6 base address write data through the inlet 85 unit 8 is supplied to one inputs of the elements 82 And groups.

The clock pulse from the output of the delay element 75 is also provided for direct input of the trigger 71, setting it in one state, in which the element 73 And for the next input pulse from the input 78 is closed and the element 72 And opened.

In addition, the clock pulse from the output element 73 And passes through the element 74 OR to the output 82 of the block 7 and then through the entrance 87 unit 8 is fed to a single input trigger 81, setting it in one state, in which a high potential with direct access trigger 81 opens the elements 82 And the key output of the counter 6 through the elements 82 And groups and elements 84 OR to the address output 27. Address code is issued for the address output 27 of the system as the address of record calculated values of profit.

And, finally, the clock pulse from the output element 74 OR block 7 is delayed by element 76 at the time of trigger 81 and outputted to the output 30 and the clock pulse records the contents of the adder 11, and the output 28 of the system in the database according to the address generated at the output 27 of the system.

The obtained value is also displayed on the screen of the operator workstation.

The graph of the profit function, shown in Fig, has an extremum of the defined values:

and

Depending on at what point is the system, the strategy changes in traffic volume will be different. In other words, the rule of decision will be that

point A: dM/dV>O RPK should be increased, and

for a point In: dM/dV<O RPK should be reduced.

To find the optimal value of the profit statement using this rule-making decisions, changes the value of the assigned traffic volume V and from his workplace information through the entrance 22 of the system enters in the register 47 via group elements 50 OR the new value of the traffic that will be entered into the register 47 synchronizing pulse received from the inlet 25 through the element is provided 51 OR the word clock input of the register 47. The values of the other numerical values in the registers 45, 46, 48 and 49 remain unchanged.

The start of a new cycle calculation of the optimal value of profits made by the same clock pulse input 25, which passes through the element 52 OR delay element 53 of the delay time data in the register 47 unit 2 and then enters the synchronization units of the system, which operates in the manner described above.

The difference between the operation of the system from the first cycle of calculations is that in the subsequent cycles of the synchronizing pulse from the output 69 of unit 2 through the inlet 78 of the block 7 passes only through the element 72 And, as after the first cycle calculations, the trigger 71 is left in a single state, in which the path of the synchronizing pulse through the element 73 And blocked low potential with the inverted output of the trigger 71.

As a result of this clock pulse will pass through the element 72 and to do that, first, the output 81 of the block 7 at the counting input of the counter 6, increasing its readings per unit.

Secondly, having the element 74 OR, this clock pulse from the output 82 of the block 7 through the inlet 87 unit 8 is fed to a single input trigger 81, confirming its isolated condition in which a high potential with direct access trigger 81 opens the elements 82 And p is dluca output of the counter 6 through the elements 82 And groups and elements 84 OR to the address output 27. Address code is issued for the address output 27 of the system as the address of record calculated values of profit.

And finally, this same clock pulse from the output element 74 OR block 7 is delayed by element 76 at the time of trigger 81 and outputted to the output 30 and the clock pulse records the contents of the adder 11, and the output 28 of the system in the database according to the address generated at the output 27 of the system.

Flexibility (variability) of profit in terms of traffic RPK will be equal to:

where γp- the proportion (share) does not depend on flight costs;

Rn- return flights (flight).

If γp≈70% and Rn=20%change (+/-) traffic (RPK) by 1% will lead to changes in the profit ±4,5%, i.e. significantly as so As or close to the ordinate value of Vm.

Flexibility (variability) rate (average ticket price) will be:

Then if Rn=20%, the change rate±1% will lead to changes in the profit±6%.

Method of optimizing the loading of aircraft that is implemented in this system, taking into account the elasticity of the market gives good accuracy results in problems of short-term (operational) forecasts of air traffic.

As primeramente the results to determine the optimal passenger traffic on the line Moscow - London based on the following statistics traffic received for 2003.
