Description

The invention relates to telecommunications and can be used in the design of radio-electronic technical systems for assessing operational performance. A known modeling method is implemented in the "Device for Modeling a Communication System," Russian Federation Patent No. 2251150, G 06 G 7/48, published April 27, 2005, Bulletin No. 12. The method consists of modeling the mode of delivering circular messages from the main station to N subscribers and the mode of confirming the receipt of information from subscribers to the main station under conditions of failures and restorations of communication lines in each communication direction. The disadvantage of the known method is the lack of the ability to quickly adjust the simulated communication network relative to the one actually functioning in real time, taking into account the following factors: movement of communication network elements (nodes and communication equipment); features of the physical and geographical conditions of the area where the communication network operates; changes in the structure of the communication network depending on external influences. A modeling method is known, implemented in the “Device for modeling a communication system”, Russian Federation patent No. 2286597, G 06 G 7/62, H 04 B 7/24, published 10/27/2006, bulletin No. 30. The method consists of generating pulses for transmission over a communication system, generating and storing a uniformly distributed random number ξ that determines the number N of the selected communication channel through which information exchange between subscribers will be carried out, recording the number N of the communication channel, forming and recording the state code of the Markov chain for m channels, generating a sequence of pulses m according to the number of channels, handling (reading) the conditional probability of error p according to the state code, checking the condition p + ξ> 1, if the sum of the uniformly distributed random number ξ and the conditional probability of error p is greater than one, which corresponds to an error signal, information about errors in m channels is formed, switching of the working channel is performed (simulation of a failure in the channel), if no error has occurred in the working channel, then switching of the working channel (simulation of a failure in the channel) will not occur, simulating the delivery of information to each subscriber is carried out taking into account the reliability of the communication line, the probability of delivering information over the communication lines is calculated. The disadvantage of the known method is the lack of the ability to quickly adjust the simulated communication network relative to the one actually functioning in real time, taking into account the following factors: movement of communication network elements (nodes and communication equipment); features of the physical and geographical conditions of the area where the communication network operates; changes in the structure of the communication network depending on external influences. A modeling method is known, implemented in the "Communication Network Analyzer" (RU Patent No. 2311675 G 06 F 11/25, G 06 F 15/173, published on 27.11.2007, Bulletin No. 33). The method consists of forming a graph of the studied probabilistic network, recording in the registers of the pseudo-random sequence generators the value of the probability of existence of the i -th vertex of the network graph, recording the code of the number of planned experiments, forming a sequence of pseudo-random numbers, the distribution law of which corresponds to sudden failures of the network vertices, forming a sequence of pseudo-random numbers, the distribution law of which corresponds to gradual failures of the network vertices, forming a sequence of pseudo-random numbers, the distribution law of which corresponds to failures of network branches arising due to external influences, as a result of this, forming in each of the statistical experiments a graph in which a path from the source of the graph to each of the connected vertices may or may not exist. The disadvantage of the known method is the lack of the ability to quickly adjust the simulated communication network relative to the one actually functioning in real time, taking into account the following factors: movement of communication network elements (nodes and communication equipment); features of the physical and geographical conditions of the area where the communication network operates; changes in the structure of the communication network depending on external influences. The closest in technical essence to the claimed method is the “Method for modeling communication networks” according to Russian Federation patent No. 2379750, IPC G 06 F 11/22 (2006.01), published 20.01.2010, bulletin No. 2. The prototype method consists of the following steps: initial data is specified, a graph of the probabilistic network under study is f
