www. kokanduni.uz The mechanism of information interaction of the original (A) and digital twin (B) is given
in expressions (13) - (16). Expression (13) describes the informational situation, in which a
change of the parameters and state of a real enterprise
ΔА
is replicated to a change of the
parameters of a twin
ΔВ
. In this case, there is a complete equivalence of the parameters of the
original and the twin
∆В
=
∆А
. Changes to the parameters of the twin are replicated to the set
of standardized rules of the management language Lc. As a result of the information
interaction of the made changes, management changes
Δ
B * in the twin are generated, which
is shown in expression (14). Then, the reverse process of transformation of the changes of the
twin
Δ
B * into changes of the parameters of the original
Δ
A * takes place. These changes
perform management functions and transfer the state of the original enterprise S(
ΔА
*) into
the target state S(G), as shown in expression (16). At the same time and synchronously, all the
events of the evolution of the digital twin (for example, the consequences of the automatic
execution of business logic algorithms) are reflected in material reality - either through the
actions of company employees (managed by the IEM system), or through equipment and
services, direct managed by the robots of the digital twin - websites, industrial robots,
conveyors, CNC machines, automatic cash registers, warehouse loaders and other. In the case
of directively managed equipment, the replication of the "digital twin
→
reality" changes is not
difficult: for example, the stacker-
truck receives the command “take the pallet from cell
12335R6 and leave it in the delivery area in cell E23456F3”. This command is promptly
executed. It should be noted, that personnel, involved in the direct execution of business
processes, are often the cause of errors in the executive system. Because of this, to control the
actions of employees, the visual interfaces of both the desktop console and various specialized
applications for arbitrary software platforms, in particular mobile devices, are used.
Replication of the “digital twin →
enterprise” changes with the participation of personnel in
the general case consists in waiting for the IEM operating system to transfer to a state, that
will allow the execution of this business process to continue.
Virtual conveyors are one of the new technologies, acceptable only in the digital
enterprise twin. It can also be considered as a dynamic digital model. Virtual enterprise
conveyors can be considered as a multi-agent system. Traditionally, a conveyor is a
mechanism for sequencing material pro
duction processes. The enterprise’s IEM operating
system totally synchronizes business processes of any industry, of any complexity, of any
scale. In a digital enterprise, a conveyor is modeled as a value chain (VC). Virtual conveyors
include stages, that are tightly coupled and each sharply follows the other. Any business and
any organized human activity can be modeled on value chains (conveyors). There can be
many models of VC at the enterprise, but in real practice, only a few value chains work within
a single company at a time. An employee can be a link of the VC. In the presence of a digital
twin, its activities are controlled and it is cautioned against errors. Wearing of bracelets by
high-speed train drivers can be an example. The bracelet controls its psychophysical state
and, if the driver has abnormalities, the bracelet, as a digital control device, signals this to the
control room and limits some actions of the driver, that the digital system considers
inadequate, using the technology of cyber-physical management. The day-to-day operations of
the company under the management of the IEM operating system do not require management
intervention Cybernetic management through its virtual conveyors (cybernetic reflections of
