The article presents a methodology for conducting an educational project for 8th-9th grade students, aimed at applying mathematical methods to analyze the environmental situation. Using the example of the Kozlovsky Municipal District, a model has been developed to calculate the effectiveness of implementing a separate collection system for municipal solid waste. During the project, students calculate waste generation volumes, determine the potential of recyclable fractions, and assess the economic effect of implementing the separate collection system. The practical significance of the work lies in the formation of students' ecological culture and the development of skills in applying mathematical knowledge to solve applied problems of the local community.

Ensuring fire safety is an important factor for sustainable socio-economic development. In the era of digitalization, computer programs come to the aid of calculating the parameters of simulated fire models.

This article describes the basic requirements and functions of household clothing for women during pregnancy and in the postpartum period. And also what requirements are given for designing such clothes. Imported clothing before and after the period in our country is sold at a high price and our women cannot afford to buy such expensive clothes. The establishment of the production of such special clothes in our republic using local resources would make their pains cheap, which would allow the solution of problems and increase the economy of our country.

It is important for politicians to understand public opinion. To get that, they can use not only direct quizzes, but also social networks’ posts and comments. In order to do this, they should use information system that could gather and analyze data to gat clusters – actual topics. The purpose of this article is to select clustering method as well as library for implementing code and to show some test results.

The transition to a cumulative system of professional development of teaching staff is one of the key factors in the modernization of the Russian education system at the present stage. Monitoring of existing models of accumulative systems, including their regulatory regulation at the level of regional educational systems and educational organizations implementing professional development programs, shows that the reasons for introducing this organizational model are the peculiarities of education development in the conditions of the formation of the information society, the implementation of the National Project "Education", the implementation of the competence model of education, professional standards, the involvement of teachers with basic non-pedagogical (university) education in school. An important circumstance is also the upcoming renewal of the mechanisms for financing educational services related to the allocation of funds for professional development.

The author describes certain distortions and destructive phenomena in the social environment of the city, which lead to negative social reactions. An opinion about the ongoing loss of social identity and degeneration of the aesthetic and creative context in the society’s mentality is expressed. The ways of solving the problems of creating sustainable positive conditions for the transformation of the urban environment are proposed.

This article is devoted to econometric modeling of regional economic growth factors in the Russian Federation in different regions using panel data models. The key factors that influence the level of development of a regional subject of the country are identified, and the subjects themselves are ranked according to the degree of their own development potential. The least and most favorable regions are identified, and the influence of observation factors for each region is revealed, reflected in the individual quantitative effect.

Volleyball serves can be divided into power, planning and mounted. Power serve achievements are characterized by high initial velocity, gliding type serves are characterized by irregular ball movement, and the goal of promotion is to land the ball on the side of the nearest opponent, possibly in the net. There is no theoretical analysis of these innings in the literature. The article examines the power and mounted feed.

The article describes the use of designers in the process of preparation at the Department of Environmental Design of the Saint Petersburg Stieglitz State Academy of Art and Design unique method of preparing students for the discipline of «design». The method is based on a combination of rational and irrational approaches to work on the project. The specificity of the irrational approach to work on the creation of an artistic image of an object is described. and artistic concept. The process of searching for an artistic image of an object is analyzed. The artistic image and its value in the work on the project.

In given article the technique of planning of carrying out of research and development on the basis of the volume determined models is described. Basically, the problems concerning top level of hierarchy, namely, problems of definition of the schedule chart of realization of the basic stages of research and development and volumes of expenses necessary for it are considered. The most effective and modern approach to realization of such substantiation is use of mathematical models. It is thus essential that the models applied to the decision of problems of this level, should consider not only internal properties of the enterprise are models of its organizational system, but also consider with accessible completeness of property of environment of the enterprise. As this completeness is rather limited, in view of incompleteness of the information on properties of environment of the enterprise, the planning technique should provide possibility of correction of planned offers, their recalculation under the specified data.

Development of thinking-a change in content and form,which are formed in the process of cognitive activity of the child.Senior school age-it's time to search and discover. The activity of thought in these years and the kind of productive thinking are found in unexpected, fantastical assumptions and "theories". Free operation of spatial images is a fundamental skill that combines different types of educational and labor activities. Based on the above, in our opinion, one of the tools for the development of creative thinking is modeling, in particular geometric modeling in mathematics lessons.

The article is devoted to the consideration of various approaches to the understanding of cultural tourism. The author developed a model on the organization of cultural tourism with younger students and described the educational potential of the model.

The main objective of this study is to present the sphere of housing and communal services as a system for modeling the activities of industry subsystems. The object of this study is the sphere of housing and communal services, and as a subject the features of the approach to modeling the activity of sectoral subsystems are determined. The methodological basis of the research was formed by the basic principles of the theory of operations research and the methods of economic and mathematical modeling. As a result of the research, theoretical rationale was obtained for the formation of models of sectoral subsystems in the housing and utilities sector. The novelty of the obtained results consists in the representation of the sphere of housing and communal services as a complex system and the allocation in its composition of sectoral subsystems for which theoretical approaches to their modeling were formulated.
