The scientific and applied problem of choosing suppliers of components, materials, and raw materials (CMRM) for the production of high-tech products (aircraft construction, shipbuilding, etc.) with a complex multi-level component architecture of the product is posed and solved. Much attention is paid to the study of long logistic supply chains for CMRM, considering the heterogeneous transport network (aviation transport, rail transport, road transport, etc.) with the transition of goods from one highway to another. The relevance of the topic of the publication is related to the study of the influence of the remoteness of suppliers and the heterogeneity of the transport network on the timing, costs, and risks of delivering CMRM to the production of high-tech products, considering the long supply chains that ensure the interaction between the supplier and the manufacturer. The research solves the problem of a rational choice of suppliers, considering the logistics of CMRM delivery in a heterogeneous transport environment. Due to the complexity of the problem being solved, it is complex and includes the following research stages: selection of suppliers, considering the component architecture of a complex product; formation of a logistics chain for the delivery of CMRM; a study of the effect of cargo transshipment in a heterogeneous transport environment. The solution of the second problem is associated with the choice of optimal logistics chains for the delivery of CMRM from the supplier to the manufacturers. The solution to the third problem is based on modeling the movement of goods, considering transshipment and possible risks. Mathematical methods used system analysis to represent the component architecture of a complex product; integer (boolean) programming to optimize the main logistic indicators; agent-based simulation modeling for the study of logistics chains for the delivery of goods with transshipment and possible risks (climatic, pandemic, terrorist, etc.).
The article deals with the task of developing information technology for the provision of copywriting services. The topic of the article is due to the fact that any Internet resource requires the availability of relevant content for further development. An important component for information and news portals, author's blogs, online stores, corporate and personal sites are texts. The main activity of the copywriter is the writing of texts on an order, the creation of content for sites with the deduction of audience prestige, and the requirements of search engines. A review of the dynamics of changes in popularity, seasonality, growth and fail from the side of users is presented. The existing most common providers of copywriting services are considered: the stock exchange – the site of Advego, the studio of Denis Kaplunov, freelance. The advantages and disadvantages of all types of services are revealed. An overview of the most powerful and most popular free content management systems (CMS – Content management system) Joomla, WordPress, Drupal is also presented. Taking into account the obvious advantages and disadvantages of each of these systems, it is defined that CMS is most suitable for solving the tasks and is optimal for the development of the site. To search for fuzzy duplicate Web documents, it is suggested to use the shingle algorithm. The diagram of variants of using the work of providing copywriting services is developed. To support the work of the site a database model was developed. The environment, development tools, language tools and the operating modes of the site are described. The presented site allows companies to solve such issues as reducing the cost of searching for copywriters, checking their level of qualification, time spent on organizing the process, maintaining the necessary documentation, including accounting. The texts for the customer are created faster because several people can work on them and order some other additional services presented on the site. The developed site for providing copywriting services is designed for use by large and small companies, private enterprises, individual individuals and owners of Internet resources
Національний аерокосмічний університет ім. М. Є. Жуковського «ХАІ», Україна ДУАЛЬНА ОСВІТА ЯК ПРОГРЕСИВНА ФОРМА ЯКІСНОЇ ПІДГОТОВКИ ФАХІВЦІВ ДЛЯ ІННОВАЦІЙНОГО ВИРОБНИЦТВА АЕРОКОСМІЧНОЇ ТЕХНІКИ Ставиться та вирішується задача використання нової форми навчання у вигляді дуальної освіти для забезпечення високотехнологічного виробництва, що розвивається, новими кваліфікованими кадрами з випускників технічних університетів. Представлене вирішення основної задачі розглядається комплексно у два етапи. На першому етапі аналізуються можливі напрями розвитку та модернізації високотехнологічного виробництва інноваційної продукції. Для вибору напрямку розвитку підприємства розроблено базу даних існуючих і перспективних замовлень, які впливають на конкурентоспроможність аерокосмічної продукції. Для цього використовується метод, заснований на прецедентному підході. Новий портфель замовлень потребує підготовки висококваліфікованих фахівців. Тому аналізуються вимоги до компетентностей фахівців, які повинні відповідати портфелю замовлень виробництва, що модернізується. Набір компетентностей випускників університету не завжди співпадає з вимогами роботодавців. Тому на другому етапі дослідження здійснюється вибір тих методів дуальної освіти (дистанційне навчання, віртуальна освіта, майстер-класи і т.д.), які дозволяють привести знання випускників університету до вимог к компетентностям роботодавців. Для цього використовується дуальна освіта, з урахуванням можливої індивідуальної траєкторії навчання для кожного студента. Заходи представлено у комбінованому поданні і включають різні інструменти навчання. За результатами індивідуального навчання, кожен з випускників університету повинен отримати набір компетентностей, що відповідають вимогам роботодавця. Формується база даних прецедентів, яка містить показники конкурентоспроможності продукції з новими вимогами до компетентностей випускників університету. Здійснюється оптимізація витрат, пов'язаних з дуальним навчанням. В якості математичних моделей дослідження використовується лексикографічне впорядкування варіантів та цілочисельна оптимізація. Запропонований підхід доцільно використовувати в задачах підготовки висококваліфікованих фахівців для виконання інноваційних проектів зі створення конкурентоспроможної продукції. Ключові слова: дуальна освіта; дуальне навчання; інноваційний портфель замовлень; модернізація виробництва; лексикографічне подання; оптимізація витрат. Fedorovych Oleh Yevhenovych -
The problem of research of business processes related to the organization and management of projects to create the new complex technical products in aerospace, shipbuilding, and other fields of mechanical engineering is stated and solved. The relevance of the study is related to the planning of a set of business processes, taking into account the architectural representation of the complex product being created. The study aims to develop a new method of synthesis of the multilevel complex of business processes to manage the creation of new technology, taking into account the multi-component representation of the complex product architecture. Much attention is paid to the complex product architecture, which is presented as a set of interconnected components. The following component types are outlined: components that can be reused; components that can be adapted to the requirements of the new product; innovative components. The types of components are studied in terms of the building of the set of business processes on their creation, taking into account the main indicators (costs, execution time, risks). Using the positive experience of past developments in the form of ready-to-use business processes helps to minimize the risks, and the new business solutions in their turn ensure the competitiveness of the complex product. The information base of positive past business processes in the form of precedents base is being built. The precedents base is used to find the close analogs of ready-to-use business processes. The set of business processes related to the management of complex product creation is formed. It has a multilevel representation that fully corresponds to the tree-like component architecture of the complex product. The method to synthesize the complexity of business processes that are planned to perform the tasks on the management of projects on creation of complex products for the developing enterprise is constructed. It is based on the “from top to bottom” system design principle. The optimization model to find the minimum costs, time, and risks in the process of business processes creation that takes into account the multilevel structure of the business process is built. The simulation event-based model in the form of a related agent set is used to study the successful execution of planned business processes related to the creation of the complex product. The results of this study should be used in the practice of creating innovative technical products that have a complex multi-level component architecture for the organization and planning of business processes related to development management. Mathematical methods used: systems analysis, precedent theory, lexicographic ordering, component design, integer optimization, simulation modeling.
