Abstract

The invention relates to computing, in particular, devices for simulating queuing systems. The purpose of the invention, the extension of functionality, is achieved by introducing a probabilistic relationship between blocks that mimic the successive stages of the application process.

The device solves the problem of investigating the search processes, eliminating otkazgch and make decisions about the restoration in the systems of man - machine, in which the system may malfunction due to erroneous actions of operators.

The device works in the following way.

Before starting the simulation, the triggers 2, 3, 9, 15, and 18 are reset, and the counters 7 and 2 are reset. On the sensor-I time intervals, an approximate simulation time is preset. On the Start signal, it starts counting the simulation time. The same signal triggers trigger 3 to the zero state, providing the prohibitive signal to the AND 4 element, and trigger 2 to the one state, providing the enabling signal to the And 5 element. The generator 6 of a random sequence of pulses is designed to simulate the flows of the application in the form of a series of pulses separated by random time intervals having any desired distribution law. Imguls from generator 6 through the open element I I 5 arrive at the counter 7 of the total number of wakes as well as the element And 8 ,. In the initial state, when the trigger I 9 is in the zero state, on

the element And 8 is issued permitting signal 1al, therefore the first impulse from the generator 6 passes the element And 8, and again it triggers the trigger 9 into a single one. Now the input of the second i of the element And 8 is given by the prohibiting potential,

 The impulse from the output of the element AND B, passing through the element OR 10, running-; The random time block 11 is designed to tadium the time of the first service phase of the operator's station of control station, which performs the functions of determining the causes of the disturbance of the technological process using information display means. After a random time delay unit 11 generates a pulse, which is fed to the inputs of the elements And 12 and 14 ,. In the initial state, the prohibitive potential per And 4 element is removed from the direct output of the trigger 18, the same potential is applied to the And 25 element, prohibiting the pulses from the multivibrator 24 to the element. 23, Thus, the resolving potential from the inverse output of the trigger 18 through the element OR 23 is applied to the input of the element AND 12J opening it.

the delay in this case passes only through the open element 12 and starts the block 13 of the random time delay 5 and also enters the single input of the trigger 15, transferring it to the single state. Block 13 is designed to simulate the time of the second phase of service applications associated with troubleshooting in the system. After a random delay time, block 3 generates a pulse that flows through the element OR 10 to the input of block P, as well as to the inputs of the trigger 15 and 18. In this case, the trigger 15 is transferred to the zero state., fixing the end of the second phase of the service of the application. The time of the second service phase of the application, corresponding to the time of a single state of the trigger 15, in the converter 16 is a time interval — the code is converted into a code, which then goes to the adder 17s. The pulse from the output of the block 13 flips the trigger 18 to one, ensuring the issuance of the enable signal element 14 and element 25, while the pulses from the b5 multivibrator 24 passed the open element 25j through the element OR 23. imitating in this case the time when the operator of the control center makes the decision to eliminate the malfunction j generates a pulse arriving at the entrances of the And 12 and i 4 elements.

In the process of operator's work, errors are possible, as a result of which the backside, at the time of troubleshooting, may turn out to be unfulfilled y: ju.-i also partially performed S Therefore, the service process va; -; You can & t be long and sick of not one, but several cycles of obropuzhank therefore, after the first cycle, you will have a chance to work the probabilistic connection between blocks II and 13 through the element I. 12, The likelihood of erroneous actions of the operators is determined by the pulse duty cycle, produced by:; ыва х ф ь ь 24, it is set before the simulation by the appropriate setting of the multivibrator 24

If now the pulse from block 11 of a random time delay coincides with the pulse of the multivibrator 24, then it
