Abstract In the Fourth Industrial Revolution, 4IR, manufacturing firms face more competitive environments, rapidly changing information and communication technologies (ICTs), and customers’ preferences than ever before. This paper analyzes relevant literature and proposes a systemic customer-centric knowledge-based production value chain (KPVC) to leverage distinctive core competencies (DCCs) and create sustainable competitive advantage (SCA) in manufacturing contexts. The paper introduces an integrative customer-centric KPVC model that enables companies to respond to environmental drivers, leverage DCCs, and create SCA. It adopts an exploratory approach to developing a unified and inherently interdisciplinary model based on a review of relevant scholarly literature. The KPVC integrated model comprises production value chain (PVC), knowledge management (KM) processes, and business process re-engineering (BPR) enabling activities. A successful move to KPVC requires a fully integrated and automated system allowing firms to define, track, and manage their work processes. Effective KPVC is a principal approach for leveraging DCCs in the quest for achieving SCA in today’s competitive business world and generating better values for customers and companies.

Abstract The authors main idea is to build energy plus buildings by means of architectural processes to design passive houses according to the Darmstadt Standard with additional equipment powered by renewable energy. The article presents a comparative financial analysis of passive house buildings with an additional source of power to charge electric cars in Poland and the United States. The analysis is based on market data while also taking into consideration inflation and increases in energy costs. The methodology is based on the calculations required by USA banks for obtaining credit. The emphasis is also on the distinction between commonly used term passive house and the term passive house in accordance with the Darmstadt Standard. The authors are introducing a new terminology to define buildings wrongly named as “passive”. Now Authors will name them Pseudo-Passive Buildings. The research shows that it is profitable to construct nearly zero-energy buildings with photovoltaic installation and the discounted rate on return of investment does not exceed the mortgage length.

Abstract In connection with the increase in the price of fuel based on hydrocarbons, the search and use of alternative types of fuel for machines in the mining and oil production industry is quite relevant today. Most of the existing alternative fuels by themselves cannot be considered as ready-to-use motor fuels. One of the ways to solve this problem is to use their mixtures with commercial fuels in certain ratios. This work deals with the development and research of the main characteristics of the mixer for obtaining mixed fuels based on diesel fuel and soybean oil, as well as the results of the study of the physical and operational properties of the obtained mixtures of different volume ratios of diesel fuel and soybean oil. The process of obtaining a mixed alternative fuel based on diesel fuel and soybean oil was implemented on a developed installation consisting of a mixer, the design of which is protected by a patent of Ukraine, and a gear pump. The study of the characteristics of the mixer as part of the installation showed that at a temperature of the components of the alternative fuel of 20°С, with a loss of full pressure on the mixer Δр ≈ (60-65) kPa, the volume consumption of soybean oil reached 10.7.10-6 m3/s. The time of preparation of the fuel mixture in the amount of 195 liters with a content of soybean oil of 10% ranged from 30 to 33 minutes. As research has shown, mixing soybean oil with diesel fuel in the amount of 5-50% vol. provides an improvement in viscosity-temperature properties and makes it possible to use such mixtures in diesel engines without changes in the design of the power supply system and regulation of fuel equipment, which characterizes soybean oil as a promising additive to diesel fuels to improve their technical and operational performance.

Abstract Recent months have highlighted the progressing energy crisis across Europe in connection with the severe sanctions imposed on the import of hydrocarbons and coal from Russia. This is particularly visible in Poland, where over 40% of electricity is generated from coal, while in individual households it is the primary source of heat. This situation puts the already enigmatic plans of shutting down coal mining in Poland into question. Therefore, work aimed at increasing the extraction capacity of existing shafts while maintaining the highest level of operational safety is still valid. This article concerns the issues of the fatigue life of compacted ropes used as hoist ropes in mine shafts. The discussion regarding the use of these ropes among shaft hoist users has been going on for several years. This paper presents the unique results of compacted rope fatigue tests carried out at the Central Mining Institute in Katowice. In the authors’ view, these results and their interpretation should serve to clarify several important aspects that arouse the interest of users.

Abstract The article deals with the issue of supporting the technological modernization of agriculture by investing in infrastructure surrounding the farms with the use of a financial instrument in the form of the Rural Development Program (RDP) based on the Lubuskie Voivodeship. The article describes, among other things, the importance of infrastructure and support for its development in rural areas in the process of functioning and modernization of the agricultural sector. For the purposes of the article, the data obtained from the Department of Rural Development Programs of the Lubuskie Marshal’s Office on expenditure and effects of RDP use in 2007-2020, in infrastructure investments in rural areas of the Lubuskie Voivodeship was analysed. In the article, the authors attempted to present the instrument in the form of the Rural Development Program as a tool for indirect impact on the process of modernization and transformation of agriculture in the Lubuskie Voivodeship, primarily by changing the infrastructural conditions for the functioning and development of agricultural production in rural areas.

Abstract In world practice, traditional blades used in high-speed wind turbines, both horizontal-axial and vertical-axial, have a wing-shaped profile. However, for horizontal-axial wind turbines, blades with such a profile have a fairly narrow range of operating values of the angle of attack of the incoming air flow and a low value of the moment of pulling from place. As for vertical-axial wind turbines, the self-starting of the rotor with wing blades is completely absent and additional devices are needed to start the rotor into operation. In order to ensure the self-starting of the rotor and the operation of the wind turbine at high and low wind speeds, a new shape of the blade profile was developed, called non-closed wing profile. The concept of the development is that the blade should have a configuration in which the pulling force is involved at the beginning of the movement, and then, with the establishing of the movement, a lifting force would arise, which acquires a prevailing character in the operating mode. The article presents the results of experimental studies of the aerodynamic characteristics of the developed non-closed wing blades. One of the results obtained is to determine the effect of the thickness of the blade profile on the range of values of subcritical angles of attack of the incoming air flow and the differences between the nature and range of changes in the coefficients of lifting force and pulling force in a traditional wing blade and a blade with a non-closed wing profile. Studies of the rotor model of a vertical-axial wind turbine with non-closed wing blades have confirmed the presence of its self-starting and operability even at low wind speeds.

Abstract The article concerns the computational model for analysing the stability of the BEV LHD loader. Works were carried out to develop an innovative, light battery-powered loader, which was the subject of an R&D project implemented in cooperation with Bumech S. A. Compared to the existing solutions of loaders with similar load capacity, this one is distinguished by the use of an individual electric drive in each wheel and a replaceable battery. A physical and mathematical model was developed taking into account the specificity of the BEV LHD loader. In the model, the masses of the battery, individual drives, the platform and excavated material are taken into account separately. The developed model allows determining the loader wheel pressure on the floor, depending on the location of its components’ centres of gravity, the turning angle of the machine, the amount of excavated material in the bucket and the position of the bucket. The input parameters also include the longitudinal and transverse excavation slope angles. In addition, the model enables determining the inner and outer turning radius of the loader. To verify the theoretical model, dynamic simulation tests were carried out. The results of simulation analyses confirmed the correctness of the developed theoretical model. The model was used to prepare a calculation sheet for analysing the stability on the basis of the adopted parameters. In the article, selected results of the conducted stability analyses have been presented, along with the proposed parameters ensuring the loader’s stability. The developed theoretical model enables a quick assessment of the loader’s stability, which, due to a number of innovative solutions, differs from existing designs. The structure of the loader at the design stage is subject to numerous modifications, which affect the distribution of the centres of gravity of individual components. The developed model of the loader is a useful, parameterized tool that allows assessing the stability and the values of the turning radii of the machine.

Abstract The article presents the problems of determining the mass efficiency of a rotary feeder depending on the selection of design parameters of the device, such as outer diameter, number of blades and rotational speed of the rotor. The hitherto theoretical methods of calculating the feeder efficiency were presented, as well as a new method of determining the device operation parameters was proposed. For this purpose, the numerical Discrete Element Method was used, which allowed simulating the transport of limestone powder in a cell feeder with various design variants. The results of the tests showed that the above design parameters affect the instantaneous efficiency of the feeder and thus impact the distribution of the dosed material during the operation of the device. Depending on the design solution, the simulation results gave information on the fill factor of the feeders. The study showed a significant potential of DEM simulation in the design of circular feeders intended for dosing bulk materials.
