Management of Distributed Systems Technological Complex

The article deals with the problem arising in systems with a set of consecutive separately controllable technological circuits and units. These circuits at the input and output have technological links with neighboring ones, but at the control level their integration into production provides only for the transfer of information parameters to the operator of the entire technological complex. The operator often does not have time to process the entire flow of incoming information and make corrective decisions. This leads to problems of mutual influence of such circuits and units on each other, which reduces the efficiency of management, quality of finished products and can lead to unscheduled downtime and emergencies. As a solution, it is proposed to assign some production control functions to the main ACS, allocating a special process controller and subnetwork for controlling local control and regulation systems. Then, with the help of special subsystems ("agents") it is possible to introduce corrective actions into the technological setpoints and parameters of each circuit so as to minimize the deviations of the setpoints of the finished products of the whole complex. In the case of modern production, the role of such "agents" is played by digital advisors, but they provide only possible solutions and leave the choice to the human operator. For well-established advisors built on the basis of physico-chemical, balance and technological, statistical, neural network, expert or combined natural-mathematical and physico-chemical models. As an example, the scheme of the complex of technical means of ACS of the main building of the enrichment plant "Mine No. 12" is given. As a difficulty of realization of such a solution the closedness of local control systems, especially foreign ones, is noted and as a solution the application of complex reverse-engineering methods is proposed.
