The introduction of these systems brings to a qualitatively new level the system of relations between subjects of budget procurement. The paper analyzes modern publications on the implementation of public procurement and related issues of efficiency (savings) of budgetary funds.</jats:p></jats:sec><jats:sec><jats:title content-type="abstract-subheading">Findings</jats:title><jats:p>The indicators on the basis of which the evaluation of the quality of regional procurement is determined are proposed. The architecture of the information system for decision support in the evaluation of procurement quality has been developed. The system has the property of adapting to changes in the state of the environment through the constant accumulation of statistical data characterizing the procurement and adjustment of the parameters of the mathematical model in accordance with them. A mathematical model is built into the control loop that allows ranking the indicators of budget purchases by the degree of their influence on the effective attribute. The role of a functional feature is the quality of budget procurement. The mathematical model is based on the application of the mathematical apparatus of correlation and regression analysis. The impact of each of the factor attributes on the functional attribute has been assessed.</jats:p></jats:sec><jats:sec><jats:title content-type="abstract-subheading">Originality/value</jats:title><jats:p>The mathematical model is based on the application of the mathematical apparatus of correlation and regression analysis. The impact of each of the factor attributes on the functional attribute has been assessed. Real statistics are given that characterize budget procurements carried out in retrospect. The coefficients of the linear regression model are determined based on the use of the STATISTICA application software package. The proposed decision support information system with a regression model built into it allows one to make scientifically and quantitatively sound decisions when assessing the quality of budget purchases of a region.</jats:p></jats:sec>

Assessment of the Formation of the Economic Effect of Cross-Subsidization in the Electric Power Industry

“…When the subjects of the Russian Federation are united in terms of setting uniform tariffs for electric energy transmission services, the effect of "smoothing" cross-subsidization is created for territories where it is high, thus achieving the effect of tariff reduction for the region [18,19].…”

Mathematical Models for Implementation of the Concept of Hard budget Restrictions in the budgetary system

“…Адаптивные обучающиеся модели, формально описывающие поведение экономических агентов в процессе принятия решений, построены такими авторами, как Е. Д. Стрельцова, И. В. Яковенко, С. Зиядин, А. Бородин, С. Суйебаева, Д. Пшембаева, О. С. Белокрылова, К. А. Белокрылов, С. С. Цыганков, В. А. Сыропятов [20][21][22][23][24][25]. Эти модели, построенные на основе математического аппарата теории стохастических автоматов, функционирующих в случайных средах, а также нечеткой логики, выполняют функцию поддержки принятия решений в процессе межбюджетного регулирования как фактора, занимающего первостепенное место в обеспечении экономического роста.…”

The Impact of the Business Environment on the Effectiveness of the Implementation of the Financial Strategy of the Oil and Gas Company

“…(Komarevtseva's, 2019) research examines the theoretical aspect of external factors that affect the organization, divided into groups. Other researchers (Belokrylova et al, 2020;Borodin et al, 2021;Streltsova, et al, 2019) focus on the relationship of a single indicator of the business environment to the state of organizations. For most scientists, the aspect of studying the factors of the mesolevel of the external environment is not isolated.…”

“…The factors of the meso-level for the holding, as opposed to an ordinary organization, differ, since the structure of the holding assumes its functioning in different territories, that is, the regional aspect of the location is transferred to the scale of the entire country and abroad. Relevant for the holding within the meso-level are the factors of influence that reflect the functioning of various sectors of the economy (Apergis and Payne, 2010;Belokrylova et al, 2020). Macro-level factors of the external environment remain relevant for all types of organizations.…”
