“…Customers get an opportunity to conduct electronic tenders -tenders, auctions, requests for prices and offers, optimising costs, and suppliers can participate in ongoing procurements, place information about products and services offered. More often than not, the placement of tenders is handled by specialised companies who, in addition to placing the information on the trading floor, process the result and possibly even determine the winner of the procedure [20][21].…”

The main challenges for industrial companies today are to improve the competitiveness of their products and to adapt and respond quickly to changes in the external environment. Ensuring the effective functioning of an industrial enterprise is largely determined by its procurement activities, including the reliability and consistency of the procurement process. Relevance of the topic is conditioned by the fact that procurement is one of the main components in increasing of competitiveness and efficiency of the enterprise, as the major part of costs in the cost price of the finished products is concentrated exactly in procurement. Reducing costs in procurement is one of the ways to improve the efficiency of the enterprise. This advantage can be achieved through the introduction of modern information technologies, namely automation of the process of selecting suppliers on an electronic trading platform. For this purpose, an information system for selecting suppliers on the electronic trading platform has been developed, which enables a more transparent, fast, profitable and less costly selection of the cheapest and most suitable goods for the operation of energy supplying enterprises. Procurement activities are aimed at ensuring that the energy-supplying undertaking receives the right quantity and quality of raw materials, materials, goods and services at the right time, in the right place, from a reliable and trustworthy supplier with good service and at a favourable price. Automating the supplier selection process on an electronic platform is essential in today's market environment.

“…The choice of cleaning method depends on many indicators. These include the physicochemical properties of pollutants, the state of aggregation, the concentration values of these compounds in the air, the aerodynamic characteristics of the gas flow [10][11][12][13][14], as well as the design features of the equipment [15][16][17]. Therefore, it is important to develop new effective and safe methods for purifying indoor air from VOCs.…”

Purification of air containing volatile organic compounds is an important task in many industries. This article examines the effect of corona discharge on the efficiency of the oxidation of organic mixtures. As a result of our research, we found that the consumption of ozone for the oxidation of various components of the mixture is approximately the same. This means that other particles, including water vapor, also take part in oxidation reactions.

“…The mechanism of particle capture is closely related to the parameters of the filters themselves-more precisely, to the granules, which are the filtering material-such as the method and porosity of the packing, the size, and shape of the granules; the hydrodynamic resistance of the filter depends on these parameters. The liquid or gas flow rate also makes a significant contribution to the filtration process [11][12][13][14][15][16][17][18][19][20][21].…”

In this work, a study was carried out to compare the filtering and hydrodynamic properties of granular filters with solid spherical granules and spherical granules with modifications in the form of micropores. We used the discrete element method (DEM) to construct the geometry of the filters. Models of granular filters with spherical granules with diameters of 3, 4, and 5 mm, and with porosity values of 0.439, 0.466, and 0.477, respectively, were created. The results of the numerical simulation are in good agreement with the experimental data of other authors. We created models of granular filters containing micropores with different porosity values (0.158–0.366) in order to study the micropores’ effect on the aerosol motion. The study showed that micropores contribute to a decrease in hydrodynamic resistance and an increase in particle deposition efficiency. There is also a maximum limiting value of the granule microporosity for a given aerosol particle diameter when a further increase in microporosity leads to a decrease in the deposition efficiency.
