Description

queuing systems and is an improvement of the device according to avtoev, no. 1037268. The purpose of the invention is to expand the functionality of the device by simulating a random preparation time for servicing and random time. The invention relates to specialized computer facilities and is intended to simulate the likelihood process. the value distribution and service of the incoming order between the free ones at the moment of receipt of the order of the channel of the public service system.

The purpose of the invention is to enhance the functionality by providing simulations of random preparation times for servicing and servicing a quotation.

The drawing shows a functional diagram of the device.

The device contains a control trigger I, the first 2, the second 3, the sixth 4, the fifth 5, the third 6 and the fourth 7 elements And, the first 8 and second 9 models of servicing devices, a generator unit 10 of random service pulses . .

The first 8 and second 9 models of servicing devices contain the element And 12, the first 13 and the second 14 triggers and the driver of 15 pulses.

Models 8 and 9 of the service devices are the channels of mass service. Each of the service channels can be in one of three states: occupied by application service; is in preparation for the maintenance of the next application; is free. The preparation period follows the same maintenance period.

Requirements are accepted for servicing only in the period of time when the channel is free, i.e. It is not engaged in any maintenance or preparation for it.

The presence of high unit potentials on the blocking outputs of the models of servicing devices of the witness service application. The device contains a control trigger 1, elements I2-7, the first 8 and second 9 models of the service device, the generator unit 10 random service pulses, the generator unit 11 random preparation pulses. 1 il.

It indicates the free state of the corresponding channel.

Three states are possible in the device: both channels are free; occupied by one

from channels; you are both channels.

The device works as follows.

The information is sent to the device’s information input and then to the Ia elements. Depending on the state of the control trigger 1, in which it is installed with a predetermined probability Py by the signals supplied to the installation inputs of the device,

From 1 the first channel enters either the first or the second channel through the corresponding first 2 or second 3 elements AND If there are single signals at the blocking outputs of the first 8 and second

9 models of service devices in case both channels are free. In this case, the Fifth 5 and Sixth 4 elements of the K application do not pass, since their inverse inputs contain unit potentials that block these elements. Then, through the corresponding third 6 or fourth 7 elements, the application goes directly to the information inputs of the corresponding first 8 or second 9 models of the serving device.

In the event that one of the channels is occupied, then one of the corresponding elements opening in this case

And 5 or 4 allows the passage of the application to another free channel, and the absence of a single potential at the first input of the third 6 or fourth 7 elements prohibits the passage of the application to the occupied channel.

In case both channels are busy, the application is rejected due to the absence of single potentials at the first inputs of elements 6 and 7.
