In the known system for the operational management of the train operation of the railway direction, the efficiency of managing the operational work of marshalling yards has been increased and operating costs have been reduced when forming a train schedule. It has the ability to refer to the calculation of costs when evaluating options for the operation of the station, as well as the ability to access the database on the appointment / removal of trains when choosing an operational plan option.

However, the known system is specialized for passing and working with freight trains, does not contain information about working with passenger trains, does not allow planning the budget indicators of branches and is local in nature, that is, it serves only selected stations.

As a prototype, a computer system is adopted for determining a trip pattern with minimal travel costs for an organization that intends to pay for flights for a population of passengers and for a population of predetermined routes, each of which contains the origin and destination of the trip, and is serviced by at least one from a set of transport companies, containing an input device for obtaining information about trips related to transport companies and routes of trips, a data storage device for storing information about trips received from the data input device, an output device for generating a report representing the solution of the objective function , a programmable processor for constructing an objective function based on travel information, the objective function represents the travel expenses for an organization that intends to pay for flights for a population of passengers and a population of predetermined routes, and we program The first processor is configured to construct a plurality of constraints based on the travel information, the constraints containing constraints related to the objective function, and also capable of taking into account the constraints in the objective function to determine an objective function solution that satisfies the constraints and minimizes travel costs for organizations (RU 2175776 C2, G06F 19/00, 11/10/2001).

The known system, firstly, works with transportation routes, and secondly, with transportation costs and has balancing blocks. Therefore, such a system can be used as the basis for the management system of the route network of passenger transportation. It minimizes each organization's overall travel costs by optimizing travel. Determining the travel itinerary of this invention preferably involves obtaining travel cost information by requesting current itinerary data from a computer-equipped pre-order system. Retrieving travel expense information may involve requesting previously generated travel history data from a travel history data file. Obtaining the demand and resource information and obtaining the transport company's target information may involve requesting the demand and resource information and the transport company's target information to organize a previously generated organization discount program data file.

However, the well-known system is adapted to the US transport system, it does not take into account the features of collecting and processing information on passenger transportation, adapted to the Express-3 automated control system, does not take into account the technology for assigning and canceling passenger trains and adjusting their schemes. The objective function of the solution does not evaluate the use of passenger cars, although it is expressed in terms of costs.

The technical result of the invention is to improve the efficiency of managing the route network of a large passenger company by optimizing the use of the car fleet in accordance with the predicted volume of demand for transportation, as well as by dynamically recalculating budget parameters and improving the quality of planning and integrating business processes of various blocks into a single automated system.

The system for managing the route network of a large passenger company operates as follows.

The user, through AWS 1 of the passenger car fleet management system (APCS), forms slices of the state of the car fleet and the actual slice, which are slices of the car model. which are accumulated and cleaned from unreliable and noisy data and are recorded in the database of the shaper 2 of the car model.

Information from the shaper 2 of the car model enters block 3 for entering information about new cars, block 4 for deleting information about cars from the fleet, block 5 for determining the number and forming a list of cars that cannot be repaired. From the outputs of these blocks, the information is fed to the input of block 6 for the formation of a plan for the repair of cars, which calculates (using the “mileage” algorithm or by the time of operation) candidate cars for resignation for repair and divides the car fleet into clusters of cars, each of which has specified properties and restrictions for further optimization of work To do this, from the block 7 of the memory, with the database of regulatory data recorded in it, the block 6 receives information about the current standards of maintenance, current, depot and overhaul (by type).

The first group of cars will be classified as trains running according to a fixed schedule and a stable scheme. In addition, a group of wagons will be selected, which should be used for the formation of schemes last.

These data are formed in block 8 of the formation of cars in groups and are fed to the input of block 9 for calculating the maximum possible use of rolling stock in trains, car turnover and local turnover. Block 9 solves the primary optimization problem of tying trains to train lines, taking into account information about train schedules from block 10 and about the appointment of direct and trailer cars from block 11.

The output data of block 9 (primary plan and indicators for the period under review) and up-to-date information on the allocation of office space norms from block 14 are fed to the input of module 12 for calculating the optimal use of the car fleet in trains and generating preliminary train schemes, which also receives data on the history of work from block 13 of the analysis of traffic of past periods.

Block 12 solves the optimization problem of using train schemes and generates preliminary train schemes.

These schemes are fed to the input of block 20 for calculating the car turnover and place of turnover, and from its output information is fed to the input of block 21 for calculating the cost of payment for services and the input of block 22 for generating a plan for income from passenger transportation.

These blocks calculate the efficiency of the transportation option proposed by block 12, while the functions of blocks 21 and 22 contain an element of analysis and decision-making on the admissibility or optimality of the plan. Blocks 21, 22, 23 also allow interactive interaction with system users.

The results of the blocks 21 and 22 are sent to the block 23 of the formation of the final data of the budget and are analyzed for approval according to user criteria.

Until the variant is approved by blocks 21, 22 and 23, iterative balancing takes place, which is performed by recalculating the solution in block 12 according to the given external (from blocks 23, 22, 21) constraints. Blocks 12,20,21,22,23 make up the budget coordination perimeter.

The construction of such a perimeter is a distinctive feature of the proposed system and in many respects reduces the time of the full cycle of production planning, being one of the conditions for achieving the technical result of the system.

After a consensus equilibrium is formed in the budget coordination perimeter, information about the final version of the schemes enters the block 15 for the formation of the final train schemes, which is, in fact, a means of transferring the decision to other blocks of the system. Thus, the data from block 15 enters block 16, which forms the final plan for the repair of wagons, which is transmitted to the perimeter of the wagon economy of the system. This, in turn, allows you to correct the state of the shaper 2 of the car model again and prepare the system for new calculations.

Information from the output of block 15 goes to block 17 for the approval and approval of the final train schemes and to block 18, which forms the final list of trains. These data are sent to the data transmission unit 19 for operational operation.

After that, the described process is completed.
