(2013) Ovcharuk, Vladimir; Yushchuk, Inna; Metlov, Sergei
Work on optimization of calculation process for the equipment intended for the absorption of carbon dioxide with the aim to neutralize calcium hydroxide when purifying crude juice in sugar production. Developed a mathematical model and parametric scheme to calculate the process of carbonation. Determined that the saturation with carbon dioxide of kiln gas negative impact on coefficient of its use. Was established that with the increase of CO2 in the gas efficiency of its use decreases.

Development of a modified ant colony algorithm for order scheduling in food processing plants
(2022) Korobiichuk, Igor; Hrybkov, Serhii; Seidykh, Olga; Ovcharuk, Vladimir; Ovcharuk, Andrii
This 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 algorithms

(2020) Hrybkov, Serhii; Kharkyanen, Olena; Ovcharuk, Vladimir; Ovcharuk, Iryna
Запропоновано інформаційну технологію для розв’язання задачі планування виконання замовлень по виготовленню продукції на харчових підприємствах в умовах невизначеності та ризику. Інформаційна технологія ґрунтується на комбінуванні алгоритмів мурашиної колонії, сірих вовків та генетичного, а також розробленій математичної моделі оперативного виконання замовлень. Перевагами комбінування алгоритмів є формування альтернативних варіантів планів та уникнення локальних оптимумів. Запропонована математична модель містить часткові критерії, обмеження та оціночну функцію для визначення ефективності сформованого варіанту плану виконання замовлень. Для наочності оцінки ефективності варіанту виконання замовлень запропоновано застосування пелюсткової діаграми та адитивної згортки часткових критеріїв. Математична модель дозволяє ОПР визначити будь-який набір часткових критеріїв для врахування особливостей параметрів виконання замовлень. Інформаційна технологія забезпечує швидку реконфигурацію поточного плану виконання замовлень у разі виникнення позаштатних ситуацій або необхідності термінового виконання певного замовлення. Abstract: An information technology has been proposed that aims to resolve the task of planning the fulfillment of orders for manufacturing products at food enterprises under conditions of uncertainty and risk. The information technology is based on combining the ant colony, gray wolves, and genetic algorithms, as well as the constructed mathematical model of the operative execution of orders. The advantages of algorithm combination include the formation of alternative variants of plans and the avoidance of local optima. The proposed mathematical model includes the partial criteria, constraints, as well as an evaluation function, for determining the effectiveness of the compiled plan of order execution. The application of a petal diagram and an additive convolution of partial criteria has been suggested to illustrate the clarity of a variant of order fulfillment. The mathematical model makes it possible for a DM to define any set of partial criteria to take into consideration the patterns of order execution. The information technology ensures rapid reconfiguration of the current plan of order execution in the event of emergencies or the need to urgently fulfill a certain order.

Розроблена математична модель і параметричні схеми для розрахунку процесу карбонізації. Встановлено, що теоретичний розмір сатуратора менше тих апаратів, що використовуються на цукрових заводах. Насичення сатураційного газу діоксидом вуглецю негативно впливає на коефіцієнт його використання.

(2015) Yushchuk, Inna; Ovcharuk, Vladimir; Seidykh, Olga; Vovkodav (Obizyuk), Natalia
The 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.
