“…Thus, the solution of this optimization problem is of considerable interest to a particular consumer. The task of constructing an optimal product processing schedule takes place not only in sugar production, but also in a number of other branches of the food and processing industry [24][25][26][27][28]. With the help of simple mathematical transformations, it can be reduced to the classical assignment problem.…”

The purpose of the study is to modernize IT personnel training to enhance the development of the digital economy by means of project-based learning methods. The objectives of the study are to harmonize the educational process with the needs of production and to develop appropriate educational and methodological support. The experience for the preparation of IT-bachelors at Lobachevsky State University of Nizhny Novgorod is analyzed on the example of the Sergach sugar factory modernization. The analysis of the experience gained at Lobachevsky State University of Nizhny Novgorod in applying the project approach shows the high potential of project-based training methods for IT specialists to work in the digital economy. In order for the project approach to become an effective means of training personnel to work in line with modern standards, it is necessary that the topics of projects be closely related to the actual problems facing real manufacturers. Therefore, a stable interaction between education and industry must be established. Project-based training methods using the above principles were introduced into the educational process of preparing bachelors in the area “Fundamental Informatics and Information Technology” at Lobachevsky State University of Nizhny Novgorod.

In this article, a sustainable network of distribution of agricultural items with suppliers, distribution centers, and retailers is considered. The main purpose of presenting the mathematical model in this article is to determine the optimal number and location of suppliers, assigning suppliers to distribution centers and optimal routing for the distribution of agricultural items to retailers in a predefined time window. Also, determining the optimal amount of inventory and the reorder point in retailers and distribution centers is another problem decision. To model the problem, some parameters of the model were considered non-deterministic and were controlled by the probabilistic fuzzy method. The results of solving numerical examples in different sizes showed that with the increase of the total costs of the distribution network of agricultural items, the amount of greenhouse gas emissions decreases, and the employment rate increases. Also, with the increase of the uncertainty rate, due to the increase of the real demand and the change in the optimal amount of production, distribution, storage and reorder point, the values of all the objective functions also increase. It was also observed by solving different numerical examples with NSGA II and MOGWO algorithms, these algorithms have been able to solve the problem in a much shorter period than the epsilon constraint method, and comparison indicators such as NPF, MSI, SM, and computing time show These algorithms have a high efficiency in solving numerical examples of the problem of the distribution network of agricultural items.

This study is devoted to evaluation of the effectiveness of sugar beet processing strategies, considering the factor of reducing the purity of sugar-containing solutions as a result of long-term storage of raw materials in the conditions of a specific manufacturer - Sergach Sugar Factory. The purpose of the work is to formulate recommendations on the selection of the most effective strategy for manufacturers based on assessments of the effectiveness of various sugar beet processing strategies. As a result of the study, the effectiveness of two heuristic strategies for sugar beet processing was evaluated - “greedy” and “thrifty”. The implementation of both strategies does not require a priori knowledge of all information about changes in the chemical composition of raw materials during storage and is based on current information about the characteristics of the remaining batches of raw materials to the current moment. The “greedy” strategy involves processing the batch of raw materials that currently gives the highest sugar yield, and the “thrifty strategy” - the batch that gives the minimum yield. The efficiency was evaluated by comparing the loss in sugar yield from the implementation of a heuristic strategy compared to the absolute optimum. When calculating the estimated sugar yield, data on the sugar content of various batches of beets and the purity of sugar-containing solutions in the conditions of the Sergach Sugar Factory in 2021 were considered. As a result of the study, it is shown that the “thrifty” strategy has small advantages compared to the “greedy” one. Thus, when choosing a recycling processing in practice, it is better to give preference to the “thrifty” strategy. This makes it possible to increase the total sugar production per season by 100 tons.
