The essence of the requirements lies in the closest approximation of the content of educational programs, regulated by federal educational standards, to the content of the practical activities of graduates, determined by professional standards.The conducted research is aimed at analyzing the methodological base for linking professional standards and federal state standards at the level of formation of competencies and indicators. A systematic approach to evaluating the model of educational activity made it possible to assess the change in the nature of the interaction between the requirements of the labor market and the ways to meet them within the framework of the content and main aspects of the quality of educational programs. The features of the implementation of relations between communities of employers in the process of forming professional standards and their translation into methods of evaluation tools, which are an integral part of professional educational programs, are presented.The article formulates the main results of the study, namely, the methodological problems of the quality of education and the direction of the scientifi c, methodological and organizational and methodological activities of educational organizations in the community with employers and regional bodies that coordinate the requirements for graduates.","PeriodicalId":101728,"journal":{"name":"Transport Technician: Education and Practice","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131054129","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The model of inventory management in terms of supply chain management allows you to combine the resources of enterprises and strengthen their cooperation with other industries. This model enables the rational use of stocks, accurately refl ecting demand and reducing their cost, increasing competitiveness, optimizing the overall structure of the production value chains, which is the key to ensuring the smooth transfer of information between the links of the supply chains. Such models and ideas of inventory management will be applied by an increasing number of enterprises.The development of supply chains in general and the information subsystem in particular is analyzed. The characteristics of inventory management within the framework of the supply management system are considered. The weaknesses of the traditional management model at the current stage of digitalization of transportation are identifi ed, the strengths of the new management model are shown, which will signifi cantly reduce the cost of storing stocks within the supply chain and quickly respond to customer needs. The evolution of supply chains, the digitalization of production and transport processes create the conditions for organizing a single network information platform for the logistics chain. Thus, a phase of transition to network logistics will be implemented, which will increase the effi ciency of production value chains.","PeriodicalId":101728,"journal":{"name":"Transport Technician: Education and Practice","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116808735","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Technological modernization of old systems brings enterprises to a new level and allows them to be competitive in the international market. The construction of railway lines leads to an increase in fuel consumption, which increases the emissions of various elements into the atmosphere.The creation of electric locomotives, the introduction of modern equipment, the modernization of diesel locomotives (contact-battery electric locomotive of the VL26 series) lead to a decrease in the level of atmospheric air pollution and makes it possible to reduce the maximum permissible concentrations of heavy elements in the environment.The experience of using Russian Railways technologies for energy saving and reducing the level of environmental pollution was studied.The forecasts for the use of a contact-battery electric locomotive of the VL26 series, designed to replace shunting diesel locomotives, which showed shortcomings and a loss of almost 70 % of the energy coming from the contact network, are presented.The modernization of diesel locomotives is considered, which will make it possible to reduce the consumption of fuel, oil and increase the energy effi ciency of the drive with switched reluctance machines, and therefore reduce the level of environmental pollution. The use of electrical power transmission with switched reluctance machines reduces maintenance and repair costs due to the features of electrical machines and the converter.","PeriodicalId":101728,"journal":{"name":"Transport Technician: Education and Practice","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132684141","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on the focus of modern education on the formation, in particular, of general competencies, the features of the interaction of the teacher with students in mastering the educational material are pointed out. The solution to the problem of the formation of general competencies of students from the standpoint of the effectiveness of this process is possible when the teacher uses methods for organizing the activities of students that meet certain requirements (criteria for enriching subjective experience).A theoretical analysis of the scientific, pedagogical and methodological literature was carried out, a generalization was made and the systematization of the studied material was carried out, which made it possible to identify the conditions for the successful organization of students’ activities and indicators of the formation of general competencies of future specialists. In connection with the need to develop methodological support for the organization of students’ activities from the standpoint of developing general competencies, a procedure for improving the method of organizing students’ activities chosen for a specific learning situation is presented, which allows the teacher to model new techniques based on a specific goal. On the example of studying educational mathematical problems, it is shown how the procedure for improving the technique chosen by the teacher is carried out. The results obtained can be useful not only for teachers of mathematics, but also for teachers of other academic disciplines, as well as for creating a lecture course for the advanced training program for educators.","PeriodicalId":101728,"journal":{"name":"Transport Technician: Education and Practice","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133132656","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
