(54) DEVICE FOR MODELING PROCESSES

MASS SERVICE

 the input of the first delay element 5 only when a pulse arrives at the input of the addition of 10 reversing counter 1; When a pulse arrives at the / subtracting input, 13 of the reversing counter 1, the pulse does not appear at its output.

From the output of the first element of the rear 5, a signal delayed by a constant value passes to the first input of the stock indication block 8. The second input of the stock indication unit receives a signal from the output of the reversible counter 2. If this signal is greater than zero (i.e., the contents of the reversible counter 2 is greater than zero), the pulse from the first output of the stock indication block 8 and the input of the reversible counter 2. If the output signal of the reversible counter 2 is zero, the pulse from the second output of the reserve indication unit 8 passes to the input of the addition 12 of the third reversible counter 3 and to the input of the second delay element 6.

From the second output of the reversible counter 2, the signal enters the subtraction input 13 of the reversible counter 1 and the input / second element of the zadarisk 6 only when a signal arrives at the subtraction input 14 of the reversing counter 2. When the input signal arrives at the addition input 11 of the reversible counter 2, the output OTcyi there is. The signal from the output of the second delay element 6, delayed by a constant value}, passes through the storage unit 7 to the second input of the deficit indication display unit 9, the first input of which receives a signal from the output of the reversing counter 3. If this signal is zero (t that is, the content of the reversible counter 3 is zero), then the signal from the first deficiency indication unit is fed to the input of the addition 11 of the reversible counter 2.

If the signal from the output is reverse

: counter 3 is greater than zero, then the pulse from j of the second output of the deficiency indication unit is fed to the input of subtraction 15 of the reversible counter 3. The signal at the output of the reversible counter 3 appears only at 4th

receipt of the input to the subtraction j.o

reversible counter 3 (when a signal arrives at the addition input 12 of this reversible counter, a signal does not appear at its output) and passes to the input of the subtraction 13 reversing counter 1.

The subject matter of the invention. jI

A device for simulating mass service processes, comprising a random signal generator connected to the addition input of the first reversible counter, characterized in that, for expansion; : a class of solved tasks, it contains the second and third p & up counters, the first and second delay elements, the storage unit, the indication and inventory deficit blocks, the output of the first reversible counter being connected to the one input of the inventory indication unit via the first delay element, the other

g input of which is connected to the first output I of the second reversible counter, the inputs of which are connected to the first outputs of the reserve and shortage indication units, the second outputs of which are connected to the inputs of the third reversible counter, the outputs of which are connected to the input of the first subtraction; the reversible counter and the first input of the deficit indication unit, the second input of which is connected to the second outputs of the stock indication unit and the second reversible counter via the storage unit and the second delay element and to the subtracting input of the first reversible counter.
