The value of the indicator

for the calculation of a task in variants,
a
the system without
agents,
b
the system with the agents
A
g
1
and
A
g
2
as well as,
c
the system with the agents
A
g
1
,
A
g

and
A
g

disappears because tasks are generated and the system becomes saturated with the
tasks. At that time, the agents
A
g
2
are activated, which are responsible for searching
for free nodes that may receive an overflow of tasks. In the course of calculations and
after blocking the generation of new tasks there is a decrease in the task saturation in
the system, and then their underflow. It results in the need for the agents searching for
the tasks
A
g
1
, whose number begins to increase and the role of agents
A
g
2
becomes
less important, hence a decrease in their number. The number of unemployed agents
increases when the agents
A
g
2
are “re-skilled” to the agents
A
g
1
. This operation takes
place due to the agents
A
g
3
. The graph
NA
g
presents the cumulative number of
agents which is held at the constant level. Therefore, the stabilization of the number
of agents in the system takes place, and at the same time, due to unemployed agents
it is possible to “re-skill” agents and ensure functional scaling of the system.
