Purpose: The paper presented here was intended to describe the extent to which secondary technical education in Poland is oriented towards the acquisition of qualifications needed in modern factories in line with the Industry 4.0 concept. Design/methodology/approach: The study was conducted by analysing information contained in the Ministry of Education and Science's classification of vocational education professions and in the core curriculum for vocational education professions. The professions analysed were those which, according to literature research, are the most desirable in an industry based on the concept of Industry 4.0. Information contained on the websites of selected schools was also analysed. Findings: As a result of the analysis carried out, it was found that the knowledge describing the qualifications of future technical staff in terms of Industry 4.0 is insufficient or even negligible. The core curricula do not require teachers in technical schools to address issues related to the concept of Industry 4.0. A lack of concepts related to Industry 4.0 in both the learning objectives and outcomes and professional qualifications was identified. Research limitations/implications: The research concerned only the professions taught in Poland in 5-year technical schools on the base of the primary school. Comparison of the studied aspects in other countries, e.g. the European Union, is difficult and requires more in-depth research. This is due to the diversity of systems of secondary technical education in individual countries and the non-uniform form of curricula. Practical implications: Several important conclusions emerge from the study. First and foremost, it should be emphasised that Polish schools do not prepare students studying in them for the phenomenon of dynamic development of manufacturing techniques represented by the idea of Industry 4.0. Graduates are not familiar with the assumptions, opportunities and threats related to it. Even if the substantive preparation of school graduates meets the requirements and expectations of Industry 4.0, schools do not promote this fact among potential candidates. Originality/value: The paper presents the state of qualification requirements in Polish secondary technical schools in the context of the development of manufacturing techniques associated with the concept of Industry 4.0. It answers the question of whether and to what extent curricula and professional qualifications contain requirements concerning knowledge of Industry 4.0? The results of the study may be an element in the discussion on the condition of Polish vocational education in the context of requirements for employees in modern factories.

Purpose: The research presented here was intended to describe to what extent secondary technical education is prepared to educate staff for the needs of Industry 4.0. Design/methodology/approach: The research was conducted by analysing the education offer of Polish and Silesian technical secondary schools while identifying professions that are important for the development of Industry 4.0 concept in production enterprises. The results obtained on a national scale were compared with those of the Śląskie voivodship. Findings: During the research it was found that the education offer in terms of preparation of future technical staff for the needs of Industry 4.0 is not sufficient and definitely not diversified enough. Among the “professions of the future” the profession of IT technician definitely prevails and its share in the offer is several times higher than that of other professions. Research limitations/implications: The research concerned only the offer of Polish secondary schools and not the actual number of students attending them. It is also difficult to accurately compare the values under study in the rest of the European Union due to the diversity of secondary education systems across countries. Practical implications: The research conducted shows that there is a need for greater promotion among young people of those faculties that are relevant from the perspective of requirements of the Industry 4.0. The promotion should take place both at the level of government and local authorities with active participation of industry representatives. Originality/value: The paper presents an analysis of Polish, and in particular Silesian technical secondary schools from the point of view of the opportunities they offer to graduates of primary schools wishing to gain a profession of a technician useful in their future careers in modern enterprises following the concept of Industry 4.0. The research results can serve as a starting point for analysis of the condition of Polish education in the context of requirements of employers wishing to employ qualified staff useful in modern production facilities in the future.

Cementing of casing string is a final operation before the next stage of well construction; it provides maximum operational life of the well. Cementing of casing string is carried out with the use of technology, based on squeezing of the whole volume of drilling mud by special grouting composition. The main purposes of cementing include isolation of water-bearing horizon, strengthening of borehole walls in unconsolidated and unstable rocks. Well cementing process is divided into five subsequent operations. Firstly, grouting mixture is prepared in concrete mixers (cementing units) with necessary water-to-cement ratio and additives. Secondly, prepared grouting solution is injected in a well. Thirdly, the solution is squeezed into the space between the casing pipes and wellbore walls. Then it is necessary to wait until the cement sheath is hardened. And at last, quality control is carried out. For convenient transportation, the equipment for well cementing is installed on the truck chassis (KAMAZ, URAL and etc.). All components are poured in concrete mixer, then the water is added and everything is being mixed until formation of uniform mass, which is later pumped in a well. Oil and Gas Industry Safety Regulations say that «calculated endurance of casing string cementing should not exceed 75% of time of cement thickening, established by laboratory tests». Therefore, it is necessary to carry out all operations of injection of fluids into the well as soon as possible without any incompliances of the cementing technology. With cementing material used and its water-to-cement ratio of 0.5, the average time of cement thickening is 120 minutes, according to laboratory tests. Therefore, a set of operations of injection of fluids should not exceed 90 minutes.

Purpose: The aim of the presented investigations was to explore the possibilities of the effective use of the 8D method to improve the merchandise distribution processes. Design/methodology/approach: The application of the 8D method involved the use of support tools, such as 5Why or ABC. These tools helped to identify and categorize problems involved in the distribution of goods. Next, major problems and their causes were identified. The 8D method enabled establishing improvement, corrective and remedial actions. The last stage of the analysis was verifying the effectiveness of the implemented actions, which proved that the application of the 8D method to improve distribution processes was justified. Findings: The 8D method turned out to be an effective tool for solving problems identified in the distribution process, which proves its effective transfer from the automotive industry. Research limitations/implications: The correct use of the 8D method, which guarantees obtaining reliable and useful results, is only possible if an interdisciplinary research team is appointed. Such a team should consist of a leader and specialists from organizational units responsible for the process correctness. Small and medium-size companies may have insufficient resources to conduct investigations and analyses in a proper way. Practical implications: The discussed case study proves that it is possible to use advanced management methods in the company. Creating an efficient and experienced team should result in developing an effective mechanism for identifying the causes and solving problems in the company’s logistic processes. Originality/value: An original solution is implementation of the 8D method from the automotive industry to improve logistic processes.

Purpose: The aim of the research was to assess the effectiveness of implementing Lean Manufacturing (One-Piece-Flow) elements in a company producing shock absorbers. Design/methodology/approach: With the help of VSM, the most important problem in the production process was diagnosed, and by using the 5 Whys tool, the root causes of the problems were identified. A simulation of introducing the One-Piece-Flow system into the production line was then used to estimate the most optimal solution. After choosing the solution, it was implemented, and the results obtained were verified. Findings: As a result of the conducted analyses, the most important problems related to planning, scheduling and the flow of intermediates were identified. The 5 Whys analysis allowed for the grouping of individual problems by common causes. Detailed solutions to the problems were proposed, which were included in the future Value Stream Map. Research limitations/implications: Conducting research in a working production process is limited and faces significant resistance from managers. Practical implications: The most important effects of implementing an improvement plan were minimising inventory from 138,062 units to 25,000 units, which reduced costs and indicates reduced waste. Lead time was limited to 9.67 days from 56.96 days. Originality/value: Research results confirm the effectiveness of introducing only some solutions of the Lean philosophy. This is particularly important if the enterprise is unable to comprehensively implement the Lean Manufacturing concept due to organisational or financial reasons.

Purpose: The aim of the research was to identify problems and develop a way to improve the communication process between partners in the logistics process. Design/methodology/approach: By analysing complaints and interviewing employees, the most important problems in the process were identified. Thanks to the 5 Whys analysis, the root causes of the problems were then identified. Understanding the sources of problems was used to design and implement an IT system supporting communication between suppliers and the manufacturer. Findings: The use of a quality management tool has identified the causes of the problems observed. Three basic sources have been distinguished: lack of dedicated platform to contact the carrier, lack of a knowledge base about the means of transport available at carriers and lack of integration of documentation with a given carrier in the IT system. By knowing the sources of the problems, it was possible to design an efficient and effective IT system. Research limitations/implications: Improvement of the process was possible thanks to the involvement of top management and awareness of the necessity of changes by interested parties. Practical implications: As a result of the analyses, a coherent design of the IT system was developed, whose implementation ensured that problems in the process were reduced, including sending errors and invoicing errors, as well as a shortening of the average processing time for a single order. Originality/value: The implication of quality management tools to improve the logistics process.

The article describes the process of analysing and improving the rolling stock repair. The problem was ineffective qualification of additional works and elements to be replaced in the renovated wagons. The qualification is carried out before undertaking the repair activities. Improper qualification increases the cost of renovation and, in consequence, causes the customer to incur additional expenses, which lowers their trust in the enterprise. The aim was to reduce the number of elements qualified for renovation and, thus, lower the unplanned costs and the wagon repair time. Major problems involved in the process of qualification were identified and, owing to the use of the SD method, corrective and preventive actions were prepared and undertaken. The last stage consisted in the verification of the results obtained.
