STRUCTURING AND «WEIGHING» OF THE GOALS IN THE

A
significant step in the establishment, development and realization of the
organizational system is a pre-design analysis and modeling. The development of
modern, large-scale and complex systems revived interest in the techniques of
their modeling, including the development and analysis of the system model. We
can formulate a set of goals and factors based on the analysis of complex
organizational systems. Usually, these goals are structured, i.e. consist of
sub-goals, these sub-goals may include other sub-goals, etc. As a result, we
get a list of atomic goals. The number of sub-goals may be very large. Also we
must underline that particular elements of these atomic goals do not have an
equal impact on the main goal. The
selection of an optimal set of system goals and information technology for
system operation includes several stages. The objective of the paper is to
develop the theory and methodology of economic-mathematical modeling based on a
cognitive approach to the research methodology and decision-making for
sustainable development of regional socio-economic systems. The present study
considers the possibility of applying the cognitive analysis to the solution of
the following tasks: minimization of the local goals based on the mathematical model; selection of more
important goals among the obtained local goals; expert estimation of goals
interrelation and establishment of
goals weights for the developed model; minimization of the local goals
based on the mathematical model; construction of the model of the region
sustainable development based on the cognitive modeling methodology.
Keywords: local goals, weights of goals, expert
estimation, tree of goal, structurization of system goals, indicators of

ROBUST DECENTRALIZED INVENTORY CONTROL IN
LARGE-SCALE SUPPLY NETWORKS

National Technical University “Kharkiv
Polytechnic Institute”
Abstract.The problem of decentralized inventory control
in large-scale supply chains under uncertain but bounded external demand and
transport time-delays and in the presence of asymmetric structural constraints
on states and controls is considered. Local inventory controllersuse linear
dynamic feedback with respect to deviation of the current inventory levels from
the chosen safety levels. To suppress the influence of disturbances, modelling
external demand, while ensuring robust stability of closed local subsystems,
the method of invariant ellipsoids is used, which allowed formulating the
problem in terms of linear matrix inequalities, wherein the synthesis of
control reduced to a semi-definite programming problem. Stability analysis of
inventory control systems for large-scale supply networks with decentralized
controllers is performed using the comparison method and vector Lyapunov
functions technique.

linear matrix inequality, semidefinite programming, comparison method, robust

Abstract: The paper deals with damping of transverse
vibrations in main hydrotransport pipelines with consideration for the effect
of parametric forces. It was determined that the transverse (parametric) forces
are damped when an flexible dampimg device is installed at one end of the
pipeline. The intensity of transverse vibrations increases with the damping
factor and the liquid mass (hydro-air mixture) flow velocity in the pipeline.
Besides, the system is entirely in the low-frequency range of transverse
vibrations, which, for its part, exerts an additional effect on the
sustainability and reliability, i.e. the safe operation, of the main.

mass, flow frequency, vibration, flexible damping device.

of out-of-date ammunitionopens ample opportunities of use of fighting equipment
in the industry. At G. Tsulukidze Mining Institute, in the project framework,
based on utilized ballistite and pyroxylin gunpowder, cheap and highly effective
industrial safe explosives were developed, which application at open mining
operations, besides considerable economic benefit, provides a higher level of ecological
safety of recycling in comparison with their
destruction
on open ranges. At the Laboratory of Explosives Research and Blasting Technologies

compounds of bivalent copper with clotrimazole were synthesized, and their
composition, structure and biological activity were studied. Preparation
clotrimazole (bioligand) belongs to imidazole derivatives (heterocyclic
compounds) which combine different kinds of biological activity: antimicrobial,
antiprotozoal, antifungal etc. It is shown that, by the reaction of complex formation
with 3d-metals, both mutual enhancement of these activities and the emergence
of an essentially new anticancirogenic activity of a complex compound of copper
with clotrimazole, better than that of cisplatin, are possible. Possible
mechanisms of the anticancirogenic effect of such complexes are discussed. The
concept of the role of the formation of the specific pentacoordinate structure
of the complexes of Cu2+ with imidazole derivatives in the
enhancement of cytotoxic activity of these preparations, we proposed, is
confirmed.

Abstract. The paper deals with the structural analysis of
tumor formations. Every element of the cell has its own function. Oxidation
reactions proceed in mitochondria which supply the cell with energy. In the
cell, this energy originates a quantum process that, together with chromosomes
and the cell membrane, generates a spin field among nucleolui. Energy is
primary as an irritator in mitotic cell division. If by any reason the number
of chromosomes in the cell is less or more than in the parent cell, this will
cause significant changes in the cell. In particular, the cell division could
be accelerated. The cell division rate depends on the quantum process generated
in the cell, which also determines the character of a tumor formation. The
location of tumor is covered by a kind of film. The information is transmitted
to all cells like in the case of DNA. This must make it easier to obtain the
information about the existence of a tumor formation.
