The article considers the actual problem of the ecology of urban areas associated with air pollution by industrial and energy enterprises. The study is aimed at substantiating the method of forming a plan for atmospheric air pollution observation using mobile laboratories. The quantitative characteristic of sites for different urban development zones is determined as a set of estimates. The air pollution index was chosen as a total sanitary and hygienic criterion for assessing pollution. The implementation of the decision-making problem using the analytic network process method is considered. Parameters of the city and environment that affect the assessment of atmospheric air quality were selected in the course of the study. A network structure of mutual influence of the studied parameters is formed. The architecture of the decision support system based on the proposed method is given. The created software makes it possible to automate the modeling of the distribution of pollutants in the atmosphere. The computational experiment is presented on the example of the Volgograd agglomeration, Russia. The proposed approach can significantly improve the organization of monitoring by mobile laboratories and reduce the cost of obtaining data on urban air pollution without increasing the number of existing observation laboratories, both stationary and mobile.

In the future, digital technologies will make it possible to increase the transparency of the economic activities of tax organizations, the transparency of the economy of all economic entities in Russian Federation, which guarantees the stability of receipts to the country's budget, an improvement in the quality of budget planning and economic stability. The purpose of this study is to substantiate the optimization of the economic activities of tax organizations based on the introduction of digital technologies. The object of the research is the economic activity of tax organizations. The subject of the research is digital technologies as a factor in optimizing economic activity and the sustainability of tax organizations. The analysis of the efficiency of tax organizations is presented. The author's vision of the influence of digital technologies on the optimization of economic activity is given on the example of the branch of the Federal Tax Service of the Russian Federation in terms of tax control and the provision of public services. It is concluded that the optimization of the economic activities of tax organizations based on the introduction of digital technologies will reduce the costs of current activities, tax administration, time costs for tax transactions.
