Ivery Prangishvili Laboratory 31
Data-Analysis and Control Systems»

Laboratory 31 was founded in 1964 under the guidance of Doctor of Sciences (Eng.), Member of the Georgian Academy of Sciences, Professor Ivery Prangishvili who led it from 1964 to February 2006.

Ivery Varlamovich Prangisvili was an outstanding researcher in the field of theory and development of the processes and systems of control, informatics, and computer engineering. In 1959 Ivery Varlamovich defended the candidate thesis in engineering. He developed a remote control unit that was required in a number of applications. This unit was based on a new philosophy and novel hardware. The Tank Department of the USSR Defense Ministry took special interest in using it for control of the targets at the tank firing grounds.

In 1969 Ivery Varlamovich defended the doctoral thesis «Principle Underlying Design of Homogeneous Structures for Logical and Computing Devices." In 1970 he was nominated the Deputy Director for Science and in 1987 was approved as the Institute Director.

I.v. Prangishvili proposed a new promising line of design of the elements and units of the control and computer systems on the basis of the homogeneous microelectronic structures (HS). Subsequent development of HS by I. L. Medvedev in collaboration with S.Ya. Vilenkin under the leadership of I.v. Prangishvili gave rise to the high-performance multiprocessor high-performance computer systems PS-2000 that were oriented to the high-dimensionvector-matrix problems.

The PS-2000 family computers exemplified the union of the actual needs and leading ideas embodied with the use of the domestic technologies. Relying on the joint designs with the IPU RAS, the NIIUVM (Severodonetsk) manufactured between 1981 and 1988 242 PS-2000 systems of which several operated from 1982 to 1997 at the Space Flight Control Center.

At the same time, v. V. Ignatushchenko in collaboration with laboratory 46 (E. A. Trakhtengerts) designed computer systems PS-3000 with multiple flows of instructions and data that were intended for the upper levels of the complex hierarchical high-performamce control systems. The first computers were manufactured at NIIUVM (Severodonetsk) only at the late 1980’s. Their finishing and production were aborted because of the changes in this country.

In the mid-1990’s the Russian nuclear industry began its invasion of the world’s market. Some countries such as Iran, India, China, and others manifested interest in buying the domestic power-generating units with light-water reactors of the VVER-1000 type. This gave rise to the need for automated control systems for the upper-level control unit of the nuclear power stations. This control unit has to implement the algorithms for monitoring, control, and diagnosis, system for representation of the NPS safety parameters, system to register the critical operational parameters, and so on which are necessary according to the requirements of the International Atomic Energy Agency.

Design of a basically new control system for the upper level of NPS was assigned to the Trapeznikov Institute of Control Sciences under the general leadership of the Institute’s Director I.v. Prangishvili (responsible executives M. A. Zuenkov and A. G. Poletykin).

Developed were the mathematical apparatus to create program systems based on the fuzzy logic, ABIS programming language, programs for rule generation from the data of modeling complex processes, and fuzzy knowledge bases for qualitative modeling. A number of new information technologies applicable in various fields including the power-industry enterprises, chemical and other industries were developed in the course of this work.

The studies enabled design of the NPS process control system with the integrating part, the upper-level computer system centralizing the data flows and offering to the NPS personnel reliable and fast facilities for station control.

In his last years Ivery Varlamovich Prangisvili was engaged in the studies of the system approach to control and identification of the systemic regularities in the natural and social systems. Origination of the conflict and crisis situations in the social control systems was determined, and the means to alleviate them were studied. At the same time, developed was a procedure to estimate complexity of various control systems, ecologization of science and anthropogenic systems. A number of restrictive regularities were proposed to increase control efficiency and minimize the probability of critical situations.

Doctor Alexei Grigor’evich Poletykin heads the laboratory from the mid-2006. He is with the laboratory since 1983. For the time being, the laboratory has 49 persons of which three have the doctoral and thirteen, the candidate degrees.

The laboratory is vectored to developing new methods of modeling, facilities to design and control the distributed control systems, design of new structures and network information technologies for process control including the nuclear industry, stationary and moving marine plants, systems for monitoring and registration of the power plant and environmental parameters.

The «Operator» system was developed on the basis of new information technologies for monitoring, control, and diagnosis. It includes the operating system, SCADA system, CAD, and some software systems for development, introduction, training, and support of the complex distributed information and computer systems. At all stages of designing the control system, the emphasis is laid on the criterion for safety of the NPS plants and use of all kinds of control such as the traditional control, control of designs, and operational control. The scientific results of these studies are embodied in the existing designs of NPS control systems.

The major part of the software systems was certified and is permitted for use in the safety-critical systems of nuclear power engineering.

The studies support a complex approach to the large-scale efficient control and computer systems meeting the requirements on power efficiency and information safety (cybersafety).
