• Analysis of the Effective Factors for Hotel Selection by Using the Fuzzy AHP Method

    pg(s) 79-82

    The selection of accommodation plays a crucial role in tourist trips as an unsuitable choice might affect the tourists’ activities. Decision-making related to the choice of an optimal hotel is a complex process due to the variety of factors and tourist preferences. By applying the Fuzzy AHP (analytical hierarchy process) method, this study aims to overcome uncertainty and to support the tourists’ decisions to choose the optimum hotel on the booking.com website. The adopted criteria for optimal selection include hotel rating, hotel price, Wi-Fi availability, free parking, breakfast availability, and free cancellation service. The criteria are compared to stakeholder preferences and weighted by using the FAHP method. The results show that the hotel price is the most influential criterion in hotel selection, whereas the free cancellation criterion has the lowest impact.

  • Knowledge management in education: automatic generation of materials for knowledge examination

    pg(s) 76-78

    Every teacher at any level of education builds and manages a knowledge base relevant to his subject in electronic form. This paper presents methodological principles and an example of the development of an information system for knowledge management and the preparation of materials for knowledge examination. In the developed system, collections of true statements in the form of free – unstructured text were used. A simplified notation scheme was used for hierarchies and classifications, and generically formulated problems with solutions in symbolic form (in mathematics and physics) were obtained using the SymbolicC ++ library. The developed information system enables automatic generation of knowledge tests (in PDF or HTML format), which contain the formulation of questions or problems, the exact solution as well as the offered false answers, obtained from the knowledge base

  • Innovative business development and the startup ecosystem in the era of the fourth industrial revolution

    pg(s) 32-36

    The study of the theoretical aspects of the development of innovative business has proved that the most effective form of innovative business, which can create and implement the final product, is a startup. The environment and infrastructure of a startup form its ecosystem. An innovation ecosystem includes economic agents, as well as an innovation environment consisting of ideas, rules of the game, social interactions, and culture. The state of the innovative business and the startup ecosystem of Ukraine behind its main components and institutions are analyzed, and the factors of the development of the startup ecosystem for its competitiveness among the world are determined. Government measures and initiatives should promote the emergence of a community of startup founders who will work closely with other actors in the private sector of the economy and the public sector. At the same time, the state should not assume the role of a leader, but only an initiator.

  • Sustainable development through corporate social responsibility policy in Bulgaria’s biosector

    pg(s) 194-197

    The bioeconomy, as a complementary segment of the circular economy, encompasses all sectors and systems that rely on biological and environmental resources, their functions and principles. It can lead to the discovery of new opportunities to provide food, goods and energy without depleting the planet’s limited biological resources. It can turn algae into fuel, recycle plastics, produce furniture or clothing from waste, and create organic fertilizers from industrial waste products. It has the potential to create over a million new “green jobs” by 2030. Bio-sector enterprises play a key role in accelerating the achievement of the UN’s global goals. They contribute to reducing climate change and waste, creating new jobs and building sustainable development in a modern society. Corporate social responsibility is a concept that reflects the quality of the relationship between an organization and society. According to the European Commission’s Green Paper, Corporate Social Responsibility (CSR) is “a concept that serves companies as a basis for voluntarily integrating social and environmental aspects into their business strategies and relationships with all stakeholders.”
    The purpose of this report is to examine how the principles of corporate social responsibility affect biosector enterprises in Bulgaria and the adequacy of the country’s policy to engage them to adopt global goals for sustainable development. The results of the study show that CSR is not seen as a one-time act, but as a sustainable process, helping to balance the three pillars of sustainable development – economic growth, social development and environmental protection.

  • Information-measuring system for monitoring the sanitary condition of tree stands

    pg(s) 142-147

    The article presents the results of the development of an information-measuring system for monitoring the sanitary status of tree stands. The main purpose of such a system is to minimize the impact of the operator on the results of monitoring the sanitary status of tree stands by indirectly controlling the quality characteristics of the tree sap (by establishing the dependence of these characteristics on climatic factors) with the possibility of remote monitoring and control of the process of express control. The developed monitoring system allows to conduct a contactless (remote) survey of sensors, which are recorded in close proximity to the root system of selective trees from an array of tree plantations, and further, by mathematical treatment of climatic characteristics (acidity and salinity index, air temperature) zoning temperature health status. The system also allows you to predict the dynamics of extending the areas of tree planting. This enables those responsible for tree planting to take preventative measures to prevent such droughts. The main advantage of the developed information measurement system is its complete computerization, which eliminates a number of external subjective influences by the operator or the responsible person (necessity of visual inspection of the maximum number of trees in the array, erroneous perception of visual information, etc.). This, in turn, avoids systematic methodological errors, thereby improving the accuracy, speed and reliability of the monitoring and control results of this system.

  • Implementation of UAV for environment monitoring of a Smart City with an airspace regulation by AIXM-format data streaming

    pg(s) 90-93

    One of the most expected and the most desired implementation of modern technologies is the concept of a Smart City. Meanwhile there are many buzz-words known to describe the ability of implementation of many approaches to provide control for Smart City. Many of such technologies had become known for Industry 4.0 concept, including 5G mobile Internet and autonomous aerial vehicles (so called drones). Nevertheless, there is an open question of how to provide and support limits where and when UAV (unmanned aerial vehicle) should be able or not to fly over the city. Naturally, the self-driven drones equipped with a batch of sensors and able to avoid some  obstacles would not be enough for everyday use within Smart City. Current paper is focused on discussion of possible solution to provide UAV with up-to-date data on restrictions, that may be required in a modern city.
