Abstract
The article shows that for the quantitative assessment of the quality of objects, various
methods of qualimetry are used in practice, which can be represented as a set of quantitative
assessment methods and allow making the most accurate, most informed decisions on improving
the quality of an object based on the assessment of complex quality indicators. It is determined that
the basis of qualimetry methods for assessing the quality of a multi-parameter object should be the
methods of obtaining information (instrumental, calculation, organoleptic and registration methods)
and sources of information (traditional, expert and sociological methods). The main difficulties
associated with the definition of a comprehensive indicator for assessing the quality of a multiparameter electric power facility, which are manifested in the peculiarities of the technological
process of production (generation), transmission and consumption of electricity in real time, namely
the theoretical and practical difficulties in determining real quantitative indicators for assessing the
quality of technological equipment of the technological process of electricity production, are
identified. Findings prove that when determining a comprehensive indicator for assessing the
quality of a multi-parameter electric power facility, it is important to assess the quality of all
processes used for electricity generation, namely production process as a set of all actions of the
power plant's operational personnel, technical systems and technological equipment; technological
process as part of the production process containing purposeful actions to change or determine the
state of electric energy; technological process as part of the production process containing
purposeful actions to change or determine the state of electric energy; technological process as part
of the production process containing purposeful actions to change or determine the state of electric
energy. It is proposed to use the additive method of qualimetry to determine a complex indicator in
the form of a combination of a set of single quantitative indicators of the quality of a multiparameter electric power facility, which is based on the addition of various properties of the
assessed quality of the facility and allows the mathematical model of the complex indicator to
reflect the hierarchical structure of the taken into account properties that characterize the technical
level and quality of technological equipment, production and technological processes. The article
presents an improved additive mathematical model in the form of factor analysis, which is proposed
to be used for the case when the studied performance indicator is an algebraic sum of factor quality
indicators. It is noted that the complexity of the additive mathematical model depends on the
number of hierarchical levels of the selected system of quality indicators of a multi-parameter
power engineering facility.
