The cartographic method of researching the presented\u0000 phenomenon is applied and the possible cartometric operations in the work of the tourist\u0000 GIS of the gastronomic direction are described. In this study we have developed a\u0000 technological scheme for creating gastronomic tourism routes using GIS technologies.

In this study, it is\u0000 proposed to use fuzzy-multiple analysis, the use of which will fully ensure that project\u0000 metrics are taken into account when choosing a project management methodology. Among the\u0000 alternatives of project management methodologies, the following four approaches were\u0000 chosen: cascade Waterfall methodology, Spiral model, Scrum methodology, and Kanban. All\u0000 of them are aimed at optimizing processes within the project team, facilitating and\u0000 speeding up product development. But each methodology has its own characteristics,\u0000 because it is calculated on different teams both in terms of composition and volume, and\u0000 is adapted to different projects in different ways. The question of the correct\u0000 selection of the methodology for a specific project is decided on the basis of data\u0000 about it. The work highlights the characteristics of the project that are most important\u0000 for international projects: project parameters and requirements, types of communication\u0000 tools, project risk assessment, team parameters, etc. A total of twenty-five indicators.\u0000 An important aspect in the development of the proposed model is that the solution to the\u0000 task is complicated by the vagueness of the existing recommendations regarding the\u0000 applicability of different methodologies in different cases and conditions, in\u0000 particular for the development of projects not related to software development and\u0000 having an international direction. It is proposed to solve this task by using\u0000 questionnaires. Each parameter that describes the project in the questionnaire is\u0000 considered as a set of possible values. Each methodology is considered from the point of\u0000 view of its application for specific options of answers to questionnaire questions. The\u0000 task of formalizing information for the given project management methodologies is\u0000 solved, based on the application of the mathematical apparatus of fuzzy sets. At the\u0000 same time, the membership function determines the degree of applicability of the\u0000 methodology to the parameter that corresponds to the answer option of the question given\u0000 in the questionnaire. An expert commission is elected to determine the appropriate\u0000 functions of all the mentioned approaches. To determine the management approach that is\u0000 most suitable for a given project, we estimate the distance from the project assessment\u0000 to the methodology assessment. Of all the ways to determine the distances between fuzzy\u0000 sets, the system chooses one or another metric, depending on the nature of the problem\u0000 under consideration.

The stock market and technological progress are important components of the modern world. Technology has led to fundamental changes in the way financial markets operate, starting with the very first stage of stock formation and continuing to trade those stocks. Technology has undoubtedly radically changed the way investments are made. Financial markets today are largely computerized ‒ from software-based bidding to price determination and direct clearing and settlement, computer technologies have replaced manual operations and simplified functions throughout the value chain in trading. Stock markets around the world are leveraging technological advances for Secure Transaction Management and monitoring. Until a few years ago, brokers shouted at each other for exchanging orders on the stock exchange. However, today's stock exchange trading takes place without physical contact from brokers and provides unlimited opportunities for studying market trends and buying stocks. Thanks to the introduction of technology, the stock market has become more user-friendly, providing faster settlements on transactions, increased transparency, increased security, automated surveillance, and much more.
