The purpose of the invention is to improve the accuracy of the simulation by taking into account energy costs and land costs for the pending orders.

The drawing shows a block diagram of the device.

The device contains a second decoder 1, a group of elements OR 2, a group of reversible counters 3, a trigger 4, a generator 5 flows, a unit 6, a buffer memory unit 6, a switch 7, a transport system model 8, a first statistical analyzer 9, a display unit 10, block 11 on the memory, the first decoder 12, the counter 13, the second totalizer 14, the first multiplier 15, the first adder 16, the first key 17, the dynamic memory block 18, the comparison block 19, the memory register 20, the second key 21, element 22 OR, block 23 forming the time interval, the first and second elements 24 and 25 of the delay , energy source 26, energy meter 27, second statistical analyzer 28, second multiplier 29.

The device works as follows.

In the initial state, the counters 3 are in the code 00 ... 01. These counters are designed to set the values of the parameters of the transport system model, i.e., to set the values of the number of operating transport agencies K, their capacity, speed, etc. In the initial state, the values of all parameters are minimal. The counter 13 is in the initial state in the code 00 ... 01, none of the outputs

There are no single signal decoders. 35 is the average residence time of the requests in the system. A signal proportional to this time is fed to the third input of the multiplier 15. At the output of the latter, a signal is generated that is proportional to the total cost of staying all applications in the system. This signal is fed to the input of the adder 16. At the end of a predetermined time interval, a pulse appears at the input of block 23, which is fed to the clock inputs of statistical analyzers 9 and 28 and

In block 18 of the dynamic memory, the code P ... 11 is recorded.

By issuing the command "Start trigger 4 is set to one. The same signal through the element OR 22 starts the block 23 forming the time interval. A single signal from the output of the trigger 4 turns on the generator 5 streams of the flow, at the outputs of which random pulse streams imitating 40 are being formed.

currents random for wok. These streams arrive at jj adder 16, and also start the element

They are sent to the information inputs of the block in the buffer memory and to the summing inputs of the adder 14, as a result of which a signal is formed at the output of the latter proportional to the total flux rate at the outputs of the generator 5. This signal goes to the first input of the multiplier 15, to the second input of which signal proportional to the cost of a unit of working time. The signals from the outputs of the transport system model display the states of the transport authorities 8, (their loading, location, and the values of their parameters). These signals are control delays. According to this pulse, the result of calculating the statistical analyzer 9 is transmitted to the display unit 10 and to the input of the multiplier 15. From the last output, the result is fed to the input of the adder 16. The pulse 50 at the output of the block 23 also reads the result of calculating the average value of the queue length maximums in the system channels statistical analyzer 28, which is fed to the first input of the multiplier 29. To the second input multiply 55 liters 29 a signal is given that is proportional to the cost of the area occupied by one application. The result of multiplying the mind output

for the block 6 of the buffer memory and the switch 7, and also go to the inputs of the statistical analyzer 9 and the block 10 of the display. In addition, these signals are addresses for memory block 11 and call to the output of this block the contents of the cell containing the value code for a variant of the combination of the values of the transport system parameters that arrived at the input of memory block 11.

Under the influence of control signals at certain outputs of the buffer memory unit 6, pulse streams appear that are fed to the corresponding inputs of the switch 7, statistical analyzer 9 and display unit 10. From the second group of outputs of block 6 of the buffer memory, signals representing the queue lengths of quotations in the system channels are sent to the statistical analyzer 28. The latter determines the average value of the maxima of queuing queue lengths in the system channels.

Under the influence of the control signals, the switch 7 distributes the flows arriving at its inputs to the corresponding transport authorities 8 ,. In the course of its operation, model 8 of the transport system consumes a certain amount of energy from source 26, which is counted and recalculated to the cost by energy meter 27. The value of the cost of energy consumed is fed to the input of the adder 16.

The simulation time is set by the time interval shaping unit 23. During this time, the operation of the transport system is reproduced in model 8, which is displayed in display unit 10. In the statistical analyzer, 9 calculated the adder 16, and also runs the element

24 delays. According to this pulse, the result of calculating the statistical analyzer 9 is transmitted to the display unit 10 and to the input of the multiplier 15. From the last output, the result is fed to the input of the adder 16. The pulse at the output of the block 23 also reads the result of calculating the average value of the queue length maxima in the system channels analyzer 28, which is supplied to the first input of multiplier 29. A second signal is sent to the second input of multiplier 29, which is proportional to the cost of the area occupied by the application. The result of multiplying from the output of the multiplier 29 is also fed to the input of the adder 16. The latter adds the signals at its inputs and generates at its output a signal proportional to the total cost of waiting and transporting the requisition, including the capital costs of the system, the energy consumption, the cost of occupied queue 1 1 and per square wok and the cost of lost production time. This signal is a sequential increase in the unit value of all system parameters.

If, after the next stage of the simulation, the total value of the system and transportation costs is less than the previous value, then it is recorded in the dynamic memory block 18, and the stage number is recorded in the memory register 20.

After a complete enumeration of all parameters, the counter 13 comes to the zero state at the information input of the key 17 and jg and the transfer pulse from its output opens the first input of the comparison unit 19, the second input of which receives the signal 11 ... 11 from the output of the dynamic memory 18 block ti.

After each reading of the results of the calculations, the statistical analyzers 9 and 28 are zeroed with a read pulse. 15

At the end of the predetermined delay time formed by the delay element 24, the output of the last pulse appears, which triggers the delay element 25 and arrives at the synchronization input of the comparison unit 19. Comparison unit 19 compares the signals received at its inputs. Since the signal at the first input of the comparison unit 19 is less than that at the second input, a signal appears at the output of the block 19 that compares the key 21. The code from the output of the memory register 20 through the public key 21 is fed to the input of the decoder 1. This code displays the parameter number an increase in the value of which led to minimal costs for the moment of modeling. This code is decrypted by the decoder 1 and the state of the corresponding counter 3 is increased by one.

After this, the next cycle of iterating the parameters is repeated and again at the end of the cycle the value of one of the parameters is increased by one, and so on. This continues until, in the next cycle, the reduction of total costs will not occur. In that

nothing This signal opens the key 17, after the 25th case in memory register 20 will be recorded

The result of which is the contents of the adder 16 is copied to the block 18 of the dynamic memory, and is fed to the synchronization input of the register 20 of the memory, as a result of which the contents of the counter 13 are copied to the register 20 of the memory.

After a predetermined delay time, formed by the delay element 25, the pulse appears at the output of the latter. This pulse arrives at the counting input of the counter, increasing its contents by one, and through the element OR 22 again starts the block 23 for forming the time interval. This ends the first stage of modeling and begins the second.

Since at the end of the first stage, the number 13 is recorded in the counter 13, a signal appears at the second output of the decoder 12, which increases the content of the counter 3i by one. As a result, the value of the first parameter of the system is increased by one. Similarly, after the second stage of modeling, the contents of counter 32 increase by one, but the contents of counter 3i are restored, i.e., it becomes equal to the original value, since the signal from the second output of the decoder 12 is also fed to the subtracting input of the counter B becomes equal to the original, and the value of the second parameter is increased by one. In process of modeling, the described process repeats 00 ... 00. At the end of the looping cycle, this code is decrypted by decoder 1. A signal appears at the zero output of decoder 1, which sets trigger 4 to the zero state. This is where the simulation ends. In this case, counters 3 record the values of the parameters of the transport system at which the total costs are minimal.
