The study considers the problem of geometrization of physicalmechanical properties of rocks of the
coal strata. The solution of the inverse problem of diagnostics of a condition of the geophysical parameters of
the geological space is considered. The approach is proposed for determining the parameters of the regression
equation of physical and mechanical properties on the geophysical parameters defined in the exploratory wells.
Optimization of parameters of mathematical models is based on the solution of the inverse problem of
diagnostics of a condition of the geophysical parameters by the method of fullscale modeling of the
experiment. The regularization criterion takes into account the principles of selforganization of mathematical
models of complex systems. Identification of the parameters of the regression equation carried out on the basis
of algorithm with successive selection of trends (the method of group accounting of arguments).

The study is proposed of the method for optimal design electromagnets of highprecision systems
for positioning objects in a horizontal plane, based on the solving conditionallycorrect inverse problems and
the transformation of constraints on the tractive force, flux density in the gap of the electromagnet of
highprecision system and temperature of the coil in the criteria (objective functions). Minimization of these
objective functions is performed by gradient descent numerically. In this case is solved sequence of the direct
tasks of calculation of magnetic and heat fields. The fourth criterion is the mass of the electromagnet.
Minimizing mass is performed analytically. Objective functions are ranked by importance. Method is a
modification of the method for solving multicriteria problems the method of lexicographic ordering. Modification
takes into account the features of the designed object; each objective function depends on a limited number
of parameters of the object. The formula for calculating the optimal parameters are given. The study shows the
results of experimental research. The proposed method is more effective than the known methods for example,
the method of the main criterion and the method of penalty functions. The method is highly efficient and can
be used in optimal design of a variety of electrotechnical devices.

The study shows the necessity and features of the design of distributed informationmeasuring
systems of precision multifunctional measuring complexes. The use of the ethernet family standard is the basic
technical solution for building the information level. The formulation of a mathematical model of the structure
optimization of a distributed informationmeasuring system which is reduced to a modified clustering problem
is presented. It is proposed to use an approach based on a genetic algorithm to solve the problem. The research
of the algorithm is performed by analyzing the modifications of the classical algorithm based on the variable
mutation, under which the mutation probability varies depending on the needs of the algorithm. Results of
numerical experiments showing the advantage of the proposed formulation of the problem for constructing the
architecture of a distributed informationmeasuring system are presented.

The publication is devoted to the development
of an ontological model of tools for intelligent modeling
and synthesis of the trajectories of technological processes
in electric power networks. Development includes two
levels of modeling: the level of metaontology and the
level of applied ontologies. At the upper level, the
structure of the upper level is proposed and described. At
the level of applied ontologies, the ontology of the
“digital substationdistribution network” system and the
structure for the ontology of tasks are detailed. The first
is implemented and presented in the Protégé framework
environment. The second is presented descriptively by the
example of the task of minimizing energy losses at the
level of a transformer substation with an illustration of a
functional diagram of the technological chain of its
solution. The findings of the work reflect the potential of
using the proposed solution to prepare an integrated
knowledge management system in the subject area.

Load in the utility network is predominantly
nonlinear and generating the highest harmonic
components of current in the electrical power network,
increases in the overall structure of electricity
consumption. The results of experimental measurements
and calculations for a number of household consumers as
well as information from literature sources noted in the
article indicate that the operation of modern appliances in
electrical power networks generates sufficiently large
currents of higher harmonic components of 3, 5, 7 and 9
orders of magnitude. The main share of emission of the
current harmonic components in the city electrical power
system networks is made by recreational and household
appliances (computers, laptops, printers, TVs, etc.).
Continuous growth of the specified capacity of nonlinear
asymmetric and sharply variable loads in the electric
power networks is not followed by timely implementation
of solutions aimed to improve the quality of electrical
energy, so, in recent years, the task of improving the
quality of electricity associated with reducing the impact
of higher harmonic components on the operation of
electrical equipment is becoming more and more urgent
and important. The listed measures and technical means
of influence reduction of the higher harmonic components
are considered in the article in details.
