Документ Development of a modified ant colony algorithm for order scheduling in food processing plants(2022) Korobiichuk, Igor; Hrybkov, Serhii; Seidykh, Olga; Ovcharuk, Vladimir; Ovcharuk, AndriiThis developed modified ant colony algorithm includes an additional improvement with local optimization methods, which reduces the time required to find a solution to the problem of optimization of combinatorial order sequence planning in a food enterprise. The planning problem requires consideration of a number of partial criteria, constraints, and an evaluation function to determine the effectiveness of the established version of the order fulfillment plan. The partial criteria used are: terms of storage of raw materials and finished products, possibilities of occurrence and processing of substandard products, terms of manufacturing orders, peculiarities of fulfillment of each individual order, peculiarities of use of technological equipment, expenses for storage and transportation of manufactured products to the end consumer, etc. The solution of such a problem is impossible using traditional methods. The proposed algorithm allows users to build and reconfigure plans, while reducing the time to find the optimum by almost 20% compared to other versions of algorithmsДокумент Hybrid algorithm based on fish school search and grey wolf optimizer algorithms for food enterprise management(2020) Hrybkov, Serhii; Seidykh, OlgaУ статті запропоновано гібридний метод на основі алгоритмів оптимізації для вирішення задач управління процесом виробництва харчових підприємств в умовах невизначеності та ризику. Цей гібридний алгоритм базується на алгоритмах FSS (Fish School Search) та GWO (Gray Wolf Optimizer). Перевага гібридного алгоритму полягає у формуванні альтернативних рішень завдань управління виробництвом - пошуку бажаного глобального оптимуму за прийнятий час з уникненням локальних оптимумів. The article proposes a hybrid method on the basis of optimization algorithms inspired by nature for solving problems of food enterprise production process management in conditions of uncertainty and risk. This hybrid algorithm is based on FSS (Fish School Search) and GWO (Grey Wolf Optimizer) algorithms. The advantages of algorithm hybridization are the formation of alternative solutions to the production management task of finding the desired global optimum within a reasonable time with avoiding local optimums.Документ Solution of control tasks using bat algorithm modifications(2020) Hrybkov, Serhii; Seidykh, OlgaУ роботі проведено дослідження алгоритмів кажанів та їх модифікацій. Проведено їх адаптацію для розв’язання багатокритеріальної задачі формування виробничих завдань та оперативно-календарних планів на харчових підприємствах. Проведений аналіз літературних джерел вітчизняних та зарубіжних авторів забезпечив підґрунтя для проведення дослідження. Апробація проводилась на основі статистичних даних по виконанню замовлень харчових підприємств. Обґрунтовано обрання алгоритму кажанів на основі стратегії пошуку польотів Levy, що забезпечує формування альтернативних планів виконання замовлень з урахування запропонованої математичної моделі. Використання алгоритму кажанів на основі стратегії пошуку польотів Levy для розв’язання складних багатокритеріальних задач забезпечує швидкий пошук, що є дуже важливим в реальних умовах прийняття рішень,а також може бути використаний у системах підтримки прийняття рішень. The work included research of bat algorithms and their modification to solve management tasks at food enterprises. Selection of the bat algorithm on the basis of Levy flight search strategy, which provides formation of alternative plans for order execution, taking into account the proposed mathematical model, the use of which allows to form new plans and to reconfigure existing plans in a short time, was justified.Документ Development of mathematical apparatus of the expert system for modelling ice cream recipes with specified quality parameters(2019) Breus, Natalia; Hrybkov, Serhii; Polishchuk, Galyna; Seidykh, OlgaAs a result of the development of the expert system mathematical apparatus, a set-theoretical mathematical model of the finished product quality control at the stage of operative planning of new types of ice cream with increased nutritional value has been obtained; multi-component ice cream recipes have been optimized in terms of composition; and a model for determining the optimal set of control actions in the presence of technological defects in the calculation of recipes has been built.Документ Modern approaches and methods of introduction of innovative technologies in education and scientific activity(2018) Yushchuk, Inna; Ovcharuk, Vladimir; Seidykh, Olga; Vovkodav (Obizyuk), Natalia; Andriiuk, IhorExperience of innovation activity of Ukrainian higher educational establishments confirms their ability to adapt to market requirements and to produce innovative products that are in demand using the results of this production to improve their educational and scientific work. The paper considers modern approaches and methods of introducing innovative technologies in education and research.Документ Development of a mathematical model of transportation problem with limited time(2016) Makovetska, Svetlana; Seidykh, OlgaThis work is dedicated to the development of a mathematical model of the transport problem solution (TS) with a time limit.Документ Expert systems in the educational process(2016) Seidykh, Olga; Makovetska, SvetlanaIn this paper, the use of expert systems in education.Документ The influence of constructive size of equipment on the carbonation process in sugar production(2015) Yushchuk, Inna; Ovcharuk, Vladimir; Seidykh, Olga; Vovkodav (Obizyuk), NataliaThe paper studies influence of the size of equipment for saturation in crude juice purifying process in sugar production. Parametric diagrams and a mathematical model for calculation of carbonation process are developed. It is established that theoretical size of saturator is smaller than the size of machines used in sugar factories. Saturation of carbonation gas with carbon dioxide has negative impact on its utilization rate.Документ Solution of heat equation stationary problem(2015) Makovetska, Svetlana; Seidykh, Olga; Fomenko, I.This paper aims to propose the use of information technology in solving problems of mathematical physics. The paper describes the software implementation of the solution for heat equation with the use of MathCAD mathematical package. Benefits of using information technology in solving different problems of mathematical physics were analyzed in comparison with traditional methods during university course. The specificity of combination of mathematical physics problems and built-in functions of MathCAD environment makes it possible to operate with no cumbersome expressions. Promising area of future research is methodical, mathematical and algorithmic aspects of efficient software implementations of numerical methods within MathCAD environmemt.
