Opis:
Od kilku już lat wzrasta zainteresowanie Przemysłem 4.0 (Industry 4.0 — I 4.0), który rozwija się na poziomie czwartej rewolucji przemysłowej. Zmiany następują we wszystkich obszarach funkcjonowania przedsiębiorstw oraz w ich otoczeniu. Są to bardzo dynamiczne zmiany o wieloaspektowym charakterze, dlatego rewolucyjne. Przekształceniom ulega wiele systemów gospodarczych i społecznych. Zmiany mają miejsce w systemach produkcji (cyberfizyczne rozwiązania), konsumpcji, transporcie i dostawach. Nowe technologie rozbudowane o możliwości cyfrowe znacznie zwiększają wartość produktów. Wykorzystywanie możliwości cyfrowych w połączeniu z rozlicznymi technologiami prowadzi do nowych modeli biznesowych. Zmiany dokonujące się w czwartej rewolucji przemysłowej są również zmianami w obszarze utrzymania ruchu (UR). Maszyny wyposażone w czujniki i monitorowane za pomocą algorytmów tworzą nowe możliwości dla produktywności urządzeń. W Przemyśle 4.0 proces konserwacji urządzeń jest proaktywny i polega (ogólnie ujmując) na tym, że to urządzenia informują użytkowników o ich działaniach oraz o sytuacjach przekraczających dopuszczalne (normalne) ramy ich użytkowania. Urządzenia są nawet w stanie poinstruować ekipę remontową (naprawczą), co ma robić, aby urządzenie uzyskało poprzednią sprawność. W niniejszej publikacji przedstawiono ogólne ramy zmian w zakresie UR w Przemyśle 4.0 wraz z przykładem zmian w krajowym sektorze stalowym. Część teoretyczna pracy powstała na podstawie studium literatury, a część praktyczna jest formą typu case study o charakterze historycznym i ukazuje zmiany w UR w sektorze stalowym w kraju.
For several years, Industry 4.0 (I 4.0) has been developing at the level of the fourth industrial revolution. Changes take place in all areas of business operations and in their environment. These are very dynamic and revolutionary changes. Many economic and social systems are transformed. Changes take place in production systems (cyber physical solutions), in consumption, transport and deliveries. New technologies expanded with digital capabilities significantly increase the value of products. The use of digital capabilities combined with new technologies leads to new business models. The changes taking place in the fourth industrial revolution are also changes in the area of maintenance. Machines equipped with sensors and monitored by algorithms create new possibilities for productivity. In Industry 4.0, the maintenance process is proactive and consists (generally speaking) that the machines inform users about their activities and about situations exceeding the acceptable (normal) use frames. The machines are even able to instruct the repair (repair) team what to do to ensure that the machine achieves its previous efficiency. This publication presents a general framework for changes in maintenance in Industry 4.0 with an example of changes in the domestic (Polish) steel sector. The theoretical part of the work (paper) was based on a study of literature, and the practical part is a case study with historical character because shows changes in maintenance in the steel sector in Poland.

Opis:
This paper presents the importance of the prediction of steel production in industry 4.0 along with forecasts for steel production in the world until 2022. In the last two decades, the virtual world has been increasingly entering production. Today’s manufacturing systems are becoming faster and more flexible – easily adaptable to new products. Steel is the basic structural material (base material) for many industrial sectors. Industries such as automotive, mechanical engineering, construction and transport use steel in their production processes. Prediction methods in cyber-physical production systems are gaining in importance. The task of prediction is to reduce risk in the decision-making process. In autonomous manufacturing systems in industry 4.0 the role of prediction is more active than passive. Forecasts have the following functions: warning, reaction, prevention, normative, etc. The growing number of customized solutions in industry 4.0 translates into new challenges in the production process. Manufacturers must respond to individual customer needs more quickly, be able to personalize products while reducing energy and resource costs (saving energy and resources can increase the product competitiveness). The modern market becomes increasingly unpredictable. Production prediction under such conditions should be carried out continuously, which is possible because there is more empirical data and access to data. Information from the ongoing monitoring of the company’s production is directly transferred to the prospective evaluation. In view of the contemporary reciprocal use of automation, data processing, data exchange and manufacturing techniques, there is greater access to external data, e.g. on production in different target markets and with global, international, national, regional coverage. Companies can forecast in real time, and the forecasts obtained give the possibility to quickly change their production. Industry 4.0 (from the business objective point of view) aims to provide companies with concrete economic benefits – primarily by reducing manufacturing costs, standardizing and stabilizing quality, increasing productivity. Industry 4.0 aims to create a given autonomous smart factory system in which machines, factory components and services communicate and cooperate with each other, producing a personalized product. The aim of this paper is to present new challenges in the production processes in relation to steel production, as well as to prepare and present forecasts of (quantitative) steel production of territorial, global and temporary range until 2022, taking into account the applied production technologies (BOF and EAF). For forecasting purposes, classic trend models and adaptive trend models were used. This methodology was used to build separate forecasts for: total steel production, BOF steel and EAF steel. Empirical data is world steel production in 2000-2017 (annual production volume in Mt).

Opis:
The paper presents the results of forecasts made for the volume of steel production in Poland based on actual data for the period from 2006 to 2021 with forecasting until 2026. The actual data used for the forecasts included annual steel production volumes in Poland (crude steel) in millions of tons. Basic adaptive methods were used to forecast the volume of steel production for the next five years. When selecting the methods, the course of the trend of the studied phenomenon was taken into account. In order to estimate the level of admissibility of the adopted forecasting methods, as well as to select the best forecasts, the errors of apparent forecasts (ex post) were calculated. Errors were calculated in the work: RMSE Root Mean Square Error being the square root of the mean square error of the ex-post forecasts yt for the period 2006-2021; as the mean value of the relative error of expired forecasts y*t (2006-2021) – this error informs about the part of the absolute error per unit of the real value of the variable yt. Optimization of the forecast values was based on the search for the minimum value of one of the above-mentioned errors, treated as an optimization criterion. In addition, the value of the point forecast (for 2022) obtained on the basis of the models used was compared with the steel production volume obtained for 3 quarters of 2022 in Poland with the forecast for the last quarter. Forecasting results obtained on the basis of the forecasting methods used, taking into account the permissible forecast errors, were considered as the basis for determining steel production scenarios for Poland until 2026. To determine the scenarios, forecast aggregation was used, and so the central forecasts were determined separately for decreasing trends and for increasing trends, based on the average values of the forecasts obtained for the period 2022-2026. The central forecasts were considered the baseline scenarios for steel production in Poland in 2022-2026 and the projected production volumes above the baseline forecasts with upward trends were considered an optimistic scenario, while the forecasted production volumes below the central scenario for downward trends were considered a pessimistic scenario for the Polish steel industry.

Purpose: The article presents the issues of metallurgist skills in the conditions of implementing the key technologies of Industry 4.0. The purpose of the paper was to propose a skills framework for a metallurgist in the context of Industry 4.0. Design/methodology/approach: The paper consists of an introduction and two substantive parts. The first part deals with the role of the human factor in Industry 4.0. The second part is about the skills of a metallurgist (the general framework of skills 4.0) in the transformation of metallurgical enterprises to Industry 4.0. The paper is part of the current research on skills of operators in Industry 4.0. The study uses a qualitative descriptive method referring to a critical analysis of literature about skills of the future. The article briefly reviews selected theoretical approaches to the operator-technology skills in the reality of Industry 4.0. Findings: The main result of the analysis was to bring closer the current, yet poorly scientifically recognised research about the place of human factor in the Industry 4.0 together with the structure of skills for the restructured employment in the steel industry. Research limitations/implications: In the conditions of the fourth industrial revolution and strong popularisation of the concept of Industry 4.0, enterprises must be able to reorganize human resources (HR). A new package of knowledge, new skills of employees are needed to perform tasks efficiently and to cooperate with new technological solutions of production and control and monitoring systems of manufacturing and service processes. The topic about human factor (HF) in Industry 4.0 is very actual and it will be developed according to wider and wider implementation of new (smarter) technologies in enterprises. Practical implications: Presented framework of human skills can be used to improve the skills profile of a metallurgist 4.0 (a worker in smarter steel mill). Social implications: In developing of new skills of employees in smart steelworks, besides steel mills, is needed an educational ecosystem, that joins different educational and science organizations. Originality/value: Reorganization of employment in Industry 4.0 is a new research field but very actual in the realized transformation process of enterprises. The paper is a form of introduction to discussion about new skills of operators in smart production.

Opis:
In recent years, the importance of production in cyberphysical systems - CPS characteristic of the new industry concept, which is Industry 4.0 -I 4.0, is gaining importance. Industry 4.0 enforces modification of traditional perception of production. The basis for changes in Industry 4.0 has become Internet of Things - IoT, which gives the opportunity to connect and communicate with each other such areas as mobile solutions, cloud computing, sensors, analytics and cyber security. By new technology, areas that previously operated in enterprises as separate systems can be combined and create new opportunities for industrial production (modernization of production methods and reduce employment). Industry 4.0 brings with it a number of new challenges for producers in the field of environmental protection, and related to the inclusion of cybernetic technology in physical production processes as well as distribution. Production starts and ends on the customer. Industry 4.0 is a collective term for technologies and concepts of value chain organization. The United Nations Organization for Industrial Development indicates the following environmental aspects in the perspective of the development of Industry 4.0, such as: climate change and limited access to resources, primarily to clean energy. It is assumed that changes in the production and functioning of economies will result in a decrease in the emission of harmful compounds into the atmosphere and increase the flexibility of activities for environmental protection. The purpose of this work is to present general directions of changes in the field of environmental protection in Industry 4.0. Authors present the following areas of change: energy management and material management. These areas are opportunities for environmental. In the category of threats, the growing costs of environmental protection and household expenses are pointed out. The work is based on a literature study and statistical data. Statistical data are used: integrated technologies, expenditure and costs of environmental protection, recycling of secondary raw materials and energy consumption for the EU and Poland.

Opis:
W publikacji przedstawiono analizę koksochłonności wykonaną dla polskiego sektora stalowego przy użyciu statystyki opisowej. Zasobochłonność stanowi jeden z istotnych mierników oceny zrównoważoności gospodarki, przemysłu i przedsiębiorstw. Koks jest podstawowym materiałem (zasobem) stosowanym w hutnictwie do wytwarzania stali. Koksochłonność w przemyśle stalowym jest miarą przetworzenia i zużycia koksu przez huty zintegrowane, czyli wyposażone w instalacje wielkich pieców i konwertorów. W artykule dokonano analizy koksochłonności w procesie produkcji stali w Polsce. Koksownie w Polsce oferują koks stalowy, koks odlewniczy, opałowy i eksportują koks (to wyjaśnienie jest istotne dla zrozumienia zakresu analizy). Przedstawiono także rynek koksowniczy w Polsce (zmiany w ujęciu historycznym) wraz z wolumenem produkcji koksu w latach 1995–2019. Następnie dokonano porównań wielkości produkcji koksu z wielkością produkcji surówki żelaza oraz produkcji stali wywtarzanej w technologii BF+BOF (ang. Blast Furnace + Basic Oxygen Furnace). Wykonana analiza może być użyteczna przy ocenie wpływu przemysłu koksowniczego i stalowego na zrównoważoność gospodarki w obszarze zasobochłonności, na przykładzie produkcji koksu. Wartością dodaną artykułu jest długoterminowe (historyczne) ujęcie koksochłonności. Analiza została wykonana na podstawie danych branżowych przedstawionych w ujęciu rocznym za okres minionych 25 lat. Celem badań (analizy) było ustalenie stopnia zmian w poziomie koksochłonności w aspekcie rynkowym: dostawca–odbiorca.
The publication presents the analysis of the coke intensity for the Polish steel sector using descriptive statistics. The resource intensity is one of the important measures for assessing the sustainability of the economy, industry and enterprises. Coke is the basic material (resource) used in metallurgy for the production of steel. Coke intensity in the steel industry is a measure of the processing and coke intensity (consumption) by integrated steel mills, i.e. ones equipped with installations of blast furnaces and converters. The article presents an analysis of the coke consumption in the steel production process in Poland. Coking plants in Poland offer steel coke, foundry coke, heating coke and export coke (this explanation is important for understanding the scope of the analysis). This paper presents the coke oven market in Poland (historical changes) together with the coke production volume in 1995–2019. Then, comparisons were made of the coke production volume with the pig iron production and the production of steel produced in the BF + BOF technology (short for Blast Furnace + Basic Oxygen Furnace). The performed analysis may be useful in assessing the impact of the coke and steel industry on the sustainability of the economy in the area of resource consumption, on the example of coke production. The added value of the article is a long-term historical presentation of coke intensity. The analysis was based on industry data presented annually for the past 25 years. The aim of the research (analysis) was to fix the level of coke intensity in the market relation: supplier and producer.

Opis:
The steel market in Poland has increased over the last few years in the market economy. Domestic steel producers manufacture more crude steel and steel products. The consumption of steel increases more and more every year. The value of shipments from the Polish steel sector account for approx. 3% of industrial production. The Polish economy uses and processes over 8 million tonnes of steel (apparent consumption of crude steel/semi-products) yearly (average volume of steel consumption from 2000 to 2017). The largest user of crude steel is metal good, but the largest user of finished steel products is construction (more than 40%), followed by: machinery industry (15%), automotive (about 12%), transport equipment (4%), home appliances industry (3.5%) and other industry sectors, e.g. electrical equipment, electronics. Changes in domestic steel consumption are presented in the paper. The publication presents the historical trends and forecasts of quantity (volume) of steel consumption. The analysis of steel intensity was realised on the basis of apparent consumption of steel in device on: semi-products and finished steel products. Realised analysis is the base for building of scenarios of steel production by particular sectors of industry in Poland.

Opis:
Od kilku już lat wzrasta zainteresowanie logistyką 4.0, która jest formą odpowiedzi podmiotów gospodarczych na zmiany w przemyśle na poziomie czwartej rewolucji przemysłowej. Przemysł 4.0, bo tak określany jest rozwój przemysłu w ramach czwartej rewolucji przemysłowej, tworzą przedsiębiorstwa, które utworzyły linie produkcyjne stanowiące połączenie mobilnej automatyzacji i systemów informatycznych sterowania procesami. Rozwój przedsiębiorstw nowej generacji i ich współpraca z podmiotami obsługi logistycznej dały początek nowym strukturom łańcuchów dostaw. W niniejszej publikacji przedstawiono ogólne założenia konstruowania struktury łańcucha dostaw na poziomie rozwoju przemysłu 4.0 oraz przykład ewolucji struktury łańcucha dostaw w przemyśle stalowym. Przemysł stalowy w Polsce, tak jak i inne gałęzie przemysłu, które chcą być konkurencyjne, doskonali się, by sprostać wyzwaniom nowoczesnego przemysłu 4.0. Praca ma charakter teoretyczno-praktyczny i jest połączeniem studium literatury i analizy typu case study.
For several years, there has been an increasing interest in Logistics 4.0, which is a form of response of enterprises, to changes in industry at the level of the fourth industrial revolution. Industry 4.0, such we call changes in the fourth industrial revolution, create enterprises that have created production lines that are a combination of mobile automation and process control information systems. The development of new generation manufacturing enterprises and their cooperation with logistic enterprises — gave rise to a new structure of supply chains. This publication presents the general assumptions of constructing the structure of supply chain at the level of industrial development 4.0 and an example of the evolution of the structure of supply chain in the steel industry. The steel industry in Poland, like other industries that want to be competitive, is changing to be a part of modern industry 4.0. The paper consists of a theoretical and practical part. The paper is combination of a study of literature and case study analysis.
