Окреслено основні параметри системного підходу до здійснення реінжинірингу бізнес-процесів, що дало змогу виявити і зрозуміти ключові взаємозв'язки між компонентами системи реінжинірингу. Розглянуто поєднання й інтегрування так званого "класичного" та "інноваційного" начала у межах зазначених систем. Наголошено на важливості і практичній значущості системного мислення у системах реінжинірингу. Розглянуто проблематику цілей таких систем, а також їхні входи та виходи. Здійснено експрес-тестування розробленої концептуальної моделі формування та використання систем реінжинірингу на підприємстві на предмет відповідності ознакам системи. У межах цієї моделі виокремлено та охарактеризовано низку блоків, які з позиції системного підходу можна розглядати як окремі підсистеми (інформаційна, економічна, управлінська складові та складова використання систем реінжинірингу). In today's environment, managers and business owners have an actual application to shape and keep up-to-date a business model that will be successful and enable the business entity to grow. Often such initiatives require changes in business processes of a fundamental nature. With this in mind, building a conceptual model for the formation and use of reengineering systems in the enterprise is essential. This model should integrate the relevant elements to ensure the effectiveness

Based on the methods of structural design, a system model of the enterprise is developed as the basis for intelligent management. Quantitative and qualitative effects of human–cyber–physical systems, which are the result of management intellectualization, are highlighted. The possibilities of using deviation and perturbation management methods in managing the state of enterprise development with the support of decision-making and implementation of an intelligent information system are considered. The features of making managerial decisions during intelligent enterprise management are considered. The place of the human factor in such intellectual management is highlighted, in particular, in terms of improving the ...

In these circumstances, the effectiveness of companies' foreign economic activities is primarily determined by the appropriate level of competencies of the personnel involved in this area, primarily the level of development of foreign-language competencies. Moreover, such competencies concern both the managing and managed subsystem employees and the enterprise as a whole. The paper singles out the place of foreign-language competencies of managers among the competencies in general, in the conditions of foreign economic activity of enterprises. The correlation between an employee's communicative and foreign language competence is considered, and the distinctions between these concepts, taking into account the components of the structure of communication, are revealed. At the same time, it is offered to consider foreign langu...

Наведено й охарактеризовано ключові параметри вказаного опитування. За його результатами ідентифіковано низку параметрів івент-менеджменту у вітчизняному бізнесі, а саме: рівень розуміння процесів івент-менеджменту в управлінні українськими підприємствами; рівень достатності знань щодо побудови і використання івент-менеджменту, а також рівень компетентності працівників суб'єктів господарювання у цій сфері. Виявлено також задоволеність працівників рівнем розвитку івент-менеджменту на їхньому підприємстві й ідентифіковано основні перешкоди щодо ухвалення рішень щодо вдосконалення івент-менеджменту. Визначено основні напрями діяльності суб'єктів господарювання, в яких першочергово повинно здійснюватися формування та/чи вдосконалення івент-менеджменту. Ідентифіковано основні причини виникнення проблем у сфері івент-менеджменту, джерела фінансування процесів його формування і вдосконалення на вітчизняних підприємствах, а також ключові переваги використання івент-менеджменту в українському бізнесі. Realizing the importance and necessity of event management development in the companies, owners and managers must hold input information based on the actual state of this type of management to introduce changes further, make improvements, identify potential opportunities in the direction, etc. Since there is no universal event management model, it is implemented differently by different business entities. At the same time, it is essential and relevant to see and understand particular typical contours and guidelines in domestic business. The article identified the actual state of event management formation and development in Ukraine using the method of expert interviews. It was given and characterized the critical parameters of the survey (the volume of the sample and its spatial feature, the target audience of the selection, representatives of the sampling frame, the type of expert review, the method of survey, research tools, the practice of communication with the target audience, the form of work organization, the frequency). The professionalism and representativeness of experts who participated in the study were substantiated. According to the survey, there were recognized several parameters of event management in the domestic business, namely: the level of understanding of the event management processes in the direction of Ukrainian enterprises; the level of sufficiency of knowledge concerning the construction and use of event management, as well as the level of competence of employees of business entities in this area. Also, it revealed employees' satisfaction with the event management level in their enterprises and

Given that in terms of their content the absolute majority of parameters for simulating the impact of a potential or actual incident that causes undesirable deviation for each link in the supply-production-marketing chain are fuzzy, it is feasible and necessary to use fuzzy set tools to solve the specified problem. Also, according to the results of the performed research, a set of heuristic rules for diagnosing incidents in the supply-production-marketing chain was proposed.

Achievement of the stated goal was achieved through application of system approach, morphological analysis, grouping, ordering, analysis and synthesis. Stress management in enterprises should be a separate direction of scientific research, as it has its own investigatory goal: undesirable deviations in management activity, causes of appearance, distribution, and ways of prevention, elimination or minimization of negative consequences. Moreover, stress management in enterprise as science and area of activity requires formulation of a concept that would give an opportunity to describe and explain existing facts and occurrences related to undesirable deviations. It would also become an integral part of the development of future management tools. The...

The article substantiates the expediency of taking into account the indicators of evaluation of such efficiency in the context of three management levels in accordance with the tasks performed (indicators of intellectual, managerial and technological potential). The practical application of the proposed method to assess the efficiency of innovation activity of the employees of the management subsystem of the enterprise was carried out on the example of a number of industrial companies in Ukraine. In this case, a map of expert evaluation for self-assessment (internal evaluation directly by the manager), internal evaluation (any deputy) and external evaluation (directly by the developers of the method). The scale of values of the coefficient of innovation activity of the manager was built.
