Opis:
Improving product quality while making decisions remains a challenge. The objective of this research was to develop a model that supports the precise enhancement of product quality through comprehensive analysis of possibilities, product incompatibilities, root causes, and recommended improvement actions. The model incorporated various tools and methods such as the SMARTER method, expert team selection, brainstorming, Ishikawa diagram, 5M+E rule, FAHP, and FTOPSIS methods. The study demonstrated that integrating quality management tools and decision-making methods into a unified model enables the accurate prioritization of activities for product quality management. This integrated approach represents the novelty of this research. The model was evaluated using a mechanical seal made of 410 alloy. The research findings can be valuable to enterprises seeking to enhance product quality at any stage of production, particularly for modified or new products.

Opis:
Celem rozważań jest ocena regulacji prawnej w zakresie ochrony wód w procesie produkcji rolnej z punktu widzenia Wspólnej Polityki Rolnej na lata 2023-2027. W konkluzji autor stwierdza, że obowiązująca regulacja nie zapewnia właściwej ochrony wód przede wszystkim ze względu na jej rozproszenie, zbyt słabe oddziaływanie na ochronę zasobów wodnych i niewystarczające sankcje za zanieczyszczanie tego elementu środowiska. Wyzwania, jakie wynikają ze Wspólnej Polityki Rolnej, mogą wpłynąć na poprawę obecnej sytuacji. Potrzeba ochrony wód w produkcji rolnej wymaga konstruowania regulacji prawnej w oparciu o właściwie wyważone instrumenty nakazowo-zakazowe oraz instrumenty stymulacyjne. Zachodzi konieczność usystematyzowania regulacji prawnej z uwzględnieniem kwestii bezpieczeństwa żywnościowego, zachowania zdolności produkcyjnych rolnictwa oraz racjonalnego wykorzystywania wody, gleb i powietrza w procesie produkcji rolnej.
The aim of the considerations was to assess the legal regulation of water protection in the process of agricultural production from the perspective of the Common Agricultural Policy 2023-2027. It has been established that the current regulation does not provide for adequate water protection due to, primarily, its fragmentation, weak impact on the protection of water resources and unsatisfactory sanctions currently available for polluting this element of the environment. The challenges arising from the Common Agricultural Policy are capable of influencing the improvement of the existing situation but the protection of waters in agricultural production requires constructing a legal regulation based on properly balanced preventive and incentive instruments. The legal regulation needs to be systematised taking into account the issues of food security, the preservation of the productive capacity of agriculture and the rational use of water, soil and air in the agricultural production process.

Opis:
The paper deals with the implementation of the JSW Capital Group’s (Poland) Demand and Quality Driven Production Management System (SPPJ – System Zarządzania Produkcją oparty na Popycie i Jakości) using a service-oriented architecture (SOA). The main components of the SPPJ architecture have been characterized, and the scope of their integration has been defined. The individual parts in the first area, i.e. quality management, have been described in detail. Due to the extensive nature of the issue, components in other areas, i.e. planning and scheduling, coal extraction and processing, coke production, as well as sales and logistics, have only been signalled. Results of the analysis of the implementation of particular components of SPPJ areas have also been presented. The development of the system and the way of implementation in a mining environment is important from the perspective of achieving the superior objective of the JSW Capital Group’s Quality Programme, which is to increase the efficiency of management of the exploited deposit and the volume of commercial product supply.

Opis:
Sustainable development encourages companies to anticipate actions that will help reduce their negative impact on the environment, but will also be beneficial to customers in terms of meeting their expectations. Hence, the purpose was to define the actions that can be expected from SMEs from the V4 countries when improving products and minimizing the negative impact on the natural environment. The research tool was a survey, the presented results of which were obtained from March to September 2023. They included 379 SMEs from the Visegrad Group countries, i.e. Poland, Slovakia, the Czech Republic, and Hungary. The results were analyzed using statistical tests performed in STATISTICA 13.3. For this purpose, the ANOVA test (repeated measurement designs) and the Mann Whitney U test were used to analyze statistically significant differences between the test results. Analyzes were performed at the significance level of α=0.05. The analysis showed that entrepreneurs from the V4 countries expect relatively different actions from SMEs when improving products and minimizing the negative impact on the natural environment. The results from the analysis may be useful in planning sustainable activities in SMEs from the V4 countries, so that these activities contribute to improving the quality of products and at the same time minimizing the negative environmental impact.

Opis:
Celem rozważań jest określenie charakteru prawnego i zakresu ochrony gwarantowanych tradycyjnych specjalności (GTS), a na tym tle próba sformułowania oceny, czy system GTS spełnia wyznaczony mu cel w zakresie wspierania producentów we wprowadzaniu ich produktów na rynek, ochrony tradycyjnych metod produkcji oraz informowania konsumentów o cechach tych produktów stanowiących wartość dodaną. Rozważania wykazały, że brak wyłącznego prawa do używania zarejestrowanej nazwy przez producentów produktów tradycyjnych z określonego obszaru geograficznego powoduje, że system GTS nie zapewnia im przewagi konkurencyjnej, a tym samym nie spełnia swojego celu w zakresie wspierania producentów we wprowadzaniu ich produktów na rynek. Przesądza to też o trudnościach w ochronie tradycyjnych metod produkcji w całej UE. Z kolei dzięki zastrzeżeniu zarejestrowanej nazwy oraz obowiązkowi kontroli urzędowych stosowania nazwy system GTS jest wiarygodny i dostarcza konsumentom rzetelnych (ale nie do końca jasnych) informacji na temat wartości dodanej tradycyjnego produktu.
The aim of this study was to determine the legal nature and scope of protection of traditional specialities guaranteed (TSGs) and, against this background, to assess whether the TSG scheme fulfils its purpose of supporting producers in marketing their products, protecting traditional production methods and advising consumers on the value-adding characteristics of these products. The results of the study have shown that producers of traditional products from a specific geographical area do not have an exclusive right to use a registered name, as a result of which the TSG scheme does not provide them with a competitive advantage and therefore does not fulfil its objective of supporting them in marketing their products. It also prejudges the difficulty of protecting traditional production methods throughout the EU, whereas, when the registered name is reserved and official controls of the use of the name are mandatory, the TSG scheme is credible and provides consumers with reliable ( albeit not entirely clear) information on the added value of the traditional product.

Opis:
The paper presents the analysis of IT tools selection to develop a system of deposits geological modelling as well as production designing and scheduling in a hard coal mine. The presented concept creates a subject-matter foundation of the solution supporting the decision making system in the field of production activities performance, with the use of IT solutions and monitoring of end product quality, implemented under the paradigm of so-called Intelligent Mine. A technological dialogue carried out by questionnaire surveys, supported with experts’ opinions, was applied to select the software for designing a system of deposit modelling, and for designing and scheduling of mining operations. Questionnaires originated based on presentations, covering the functionality in the field of geological data gathering, developing a geological spatial model of a bedded deposit, as well as designing and scheduling. The presented solutions were next evaluated, via questionnaires, by the employees of the company. In addition, 4 groups of criteria were prepared: technical (questionnaires), technical (experts), business, and IT, based on which the final evaluation was carried out. Ultimately, Solution 2 was selected as that, which to the highest degree satisfied technical, business, and IT requirements of the planned system. The indicated IT solution was implemented and became one of basic tools for modelling hard coal deposits, an also for designing and scheduling of the mining operations in the company.
Rozwój informatyki, automatyki i robotyki umożliwia coraz większej liczbie podmiotów zwiększenie wykorzystania technik cyfrowych lub komputerowych. Dotyczy to również branży tradycyjnych, takich jak górnictwo, dla których stosowanie narzędzi informatycznych do gromadzenia, przechowywania i przetwarzania danych również powinno być jednym z priorytetów. Grupa Kapitałowa JSW SA, zajmująca się wydobyciem węgla kamiennego oraz produkcją koksu, przeprowadziła badania w zakresie opracowania i wdrożenia systemu do modelowania złoża oraz harmonogramowania produkcji górniczej. Celem stosowania wdrożonego systemu była realizacja nadrzędnego celu Programu Jakość Grupy Kapitałowej, czyli zwiększenia efektywności zarządzania jakością złoża i produktu handlowego. W artykule przedstawiono jeden z etapów badań, którym był wybór dedykowanych narzędzi informatycznych dla potrzeb modelowania geologicznego złóż oraz projektowania i harmonogramowania produkcji. Opracowane rozwiązanie pozwala na stałą aktualizację informacji w bazie danych, szybkie ich wykorzystanie i modyfikację oraz usprawnienie procesu projektowego (roboty udostępniające, przygotowawcze, jak i eksploatacyjne). System pozwala na planowanie (krótko- i długoterminowe) eksploatacji oraz projektowanie techniczne, projektowanie robót udostępniających, przygotowawczych i eksploatacyjnych oraz wykonanie harmonogramu projektowanych robót. Umożliwia automatyczne obliczanie ilości i jakości urobku oraz skały płonnej w wybranych przedziałach czasowych oraz przygotowanie prognozy dla wszystkich parametrów dotyczących wykonanego projektu wydobycia, takich jak: ilość urobku, ilość skały płonnej, parametry jakościowe itp.

Opis:
The intensification of agricultural production is one of the factors determining economic development. Increasing mechanisation and use of fertilisers in agriculture lead to higher yields, but at the same time they can pose a threat to the environment. The overuse of chemical fertilisers contributes to increased concentration of nutrients in agricultural runoff. One of such areas is the Szreniawa River catchment, the study area located in the southern part of Poland. In this catchment, intensive mostly mechanical ploughing is applied in, for instance, vegetable production. The area has loess soils, which with intensive ploughing are susceptible to erosion. The study aims to determine changes in the quality of flowing waters against the background of agricultural production and land-use characteristics. Surface waters were classified as class II and occurred at all analysed points. The highest concentrations of N-NO3 , N-NH 4 and P-PO 4 were found at a point in the middle of the catchment (lower part of research area). There, the lowest concentrations were recorded in 2018, which was related to the amount of precipitation during the growing season. On the other hand, the volume of plant and animal production closely correlated with the quality of surface water in the area. This was also confirmed by the land use structure. In conclusion, intensive agricultural production, mainly in terms of plough tillage causes significant hazards associated with soil erosion especially on agriculturally sensitive soils, although it provides good yields.

Opis:
Today, manufacturing companies strive to find the stability between satisfying their customers by producing in accordance with their expectations (quantity and quality) and keeping leading positions when it comes to competitiveness on their markets. This paper aims to compare two very well-known philosophies in the manufacturing industry: Lean Manufacturing (LM) and Six Sigma (6S). The integration of these two philosophies solves the insufficiency that the absence of one of them causes, considering that Six Sigma is based on statistical tools that focus on measuring and reducing variations in processes and achieving goals set by the customers' requirements. Lean Manufacturing focuses mainly on the value added for a client, for example,by eliminating all kinds of waste from processes what leads to the reduction of time and cost of the process. Lean Six Sigma combines the features of both methods, which means that it meets the client's requirements based on statistical knowledge and the process flow control, but simultaneously in addition to that, it reduces the time and cost of the processes. As a result, it gives manufacturing companies the possibility of having loyal and satisfied customers and who provide companies with new customers. This paper has a greater goal of persuading the Angolan manufacturing industries to implement the Integrated Lean Six Sigma (IL6S) into their production and management processes.
Dziś firmy produkcyjne dążą do znalezienia stabilności pomiędzy satysfakcją swoich klientów poprzez produkcję zgodną z ich oczekiwaniami (ilość i jakość) a utrzymaniem czołowej pozycji, jeśli chodzi o konkurencyjność na swoich rynkach. Niniejszy artykuł ma na celu porównanie dwóch bardzo dobrze znanych filozofii w przemyśle wytwórczym: Lean Manufacturing (LM) i Six Sigma (6S). Integracja tych dwóch filozofii rozwiązuje problem braku jednej z nich, biorąc pod uwagę, że Six Sigma opiera się na narzędziach statystycznych, które koncentrują się na pomiarze i redukcji zmienności procesów oraz osiąganiu celów wyznaczonych przez wymagania klientów. Lean Manufacturing skupia się głównie na wartości dodanej dla klienta, na przykład poprzez eliminację wszelkiego rodzaju marnotrawstwa z procesów, co prowadzi do skrócenia czasu i kosztów procesu. Lean Six Sigma łączy w sobie cechy obu metod, co oznacza, że spełnia wymagania klienta w oparciu o wiedzę statystyczną i kontrolę przebiegu procesów, ale jednocześnie dodatkowo skraca czas i koszt procesów. W efekcie daje to firmom produkcyjnym możliwość posiadania lojalnych i zadowolonych klientów oraz zapewnia firmom nowych klientów. Większym celem tego artykułu jest przekonanie angolskiego przemysłu wytwórczego do wdrożenia zintegrowanej metody Lean Six Sigma (IL6S) w procesach produkcji i zarządzania.

Purpose: The aim of the article was to propose the possibility of implementing a work standardisation card for a company in the passenger land transport industry – a ski lift. Design/methodology/approach: The analysed ski lift, located in Southern Poland, should undergo daily checks on the condition of its equipment to ensure trouble-free operation. Current non-standardised operations may increase the risk of error. The proposed document, the work standardisation card, makes it possible to supervise the control and minimise the possibility of failure. Findings: The introduction of the work standardisation card allows to increase the efficiency of the work and the analysis of the results obtained allowed to classify the most time-consuming activities. Research limitations/implications: In order to reduce costs, as a result of failures, and to increase quality and customer satisfaction, it is proposed to introduce documents as part of the working standard. Practical implications: Future research should focus on opportunities to further improve machine condition monitoring. The presented methodology can be applied to other activities that occur during ski lift operation, such as breakdowns. Originality/value: The work is a useful resource for companies in the tourism and transport industry and the transport sector, due to the universality of the standards used.

Purpose: The main goal of the research was to determine the spectrum of instruments supporting management processes that are used to improve the quality of products in terms of sustainable development. We analyzed the degree of their use in the practical functioning of the surveyed enterprises. In addition, the aim of the research was to determine the scope of application of the indicated instruments or the possibility of their use in the decision-making process relating to the improvement of the broadly understood quality of products. Design/methodology/approach: The research method applied are: 1) standardized survey research making based on a survey conducted in contact and remote way conducted in 78 enterprises in south-eastern Poland; 2) analysis of the source documentation and in-depth interviews. It is a component of broader research. Findings: The following methods were used in decision-making processes with varying frequency: the Delphi method by 58% of respondents, Tree of Failure Analysis (by 52%), Event Tree Analysis (by 44%), and the QFD method (by 41% respondents). The surveyed companies that have implemented a vapour management system based on ISO standards tend to use 5 methods out of 25 cited in this study (these are a survey, brainstorming, 5Why and/or 5W2H, benchmarking, and the Delphi method). As a result of using mainly the above mentioned methods in decision-making processes, 74% (out of all) of the respondents indicated an increase in the quality level of products, and 39% of respondents indicated the enhancement of the pro-ecological impact of products on the natural environment. Research limitations/implications: Most of the analysed enterprises from SMEs are tried integrating qualitative-environmental actions as part of improving the quality of products. This approach is crucial when improving the quality of products in SMEs. Practical implications: It is necessary to develop a multidimensional modl enabling the optimization of decision-making processes with the possibility of making full use of the available instruments for improving the quality of the product in such a way as to meet the rapidly changing requirements of stakeholders. Originality/value: The article has cognitive value for development of knowledge, science, quality, and environmental in the area of management of products.

Opis:
Today, foundries are facing increasing demands for greener and more economical production while maintaining or improving the quality of the castings produced. The importance and use of green sand mixtures using bentonite as a binder are thus coming to the fore once again. They have the advantage of both eliminating the chemicalization of production and also allowing the immediate use of the already used mixture, including the binder, after adjustment of the composition and mulling. In order to maintain the quality of the resulting castings, it is necessary to monitor the properties of the moulding mixture through a series of laboratory tests. It is also essential to look at the processing quality of these mixtures, i.e. the combination of good mulling quality and efficient mulling time, which is often neglected. It is the quality of mulling and the effective mulling time that help to develop the bonding properties of the bentonite, improve the properties of the mixture, determine the efficiency of the muller and possibly reduce the time and energy required for mulling. The aim of this work is to present the effect of mulling on the properties of sand-water-bentonite mixtures. The properties studied are mainly the compactability, strength characteristics, moisture content of the mixture and the order of addition of raw materials.

Opis:
The activities of the organisation concentrate mainly on meeting customers’ requirements. For this purpose, various activities are being conducted for customer satisfaction surveys. In this context, it is important to predict the quality of the product and the changes in the cost of the purchase product. The purpose of this study is to propose a method for predicting the quality level of a product and change the cost of the product considering current customers’ requirements for a combination of product feature states and pro-quality changes. The method includes the calculation of the quality level of the product using the punctationformalised method, where the level depends on a combination of values of states (parameters) attributes of the product, that is, current and modified. The method was tested as an example of a household vacuum cleaner for which 20 attributes were determined. According to the Pareto rule (20/80), the four product attributes important for customers were selected. Thereafter, for important attributes, possible combinations of the values of these attributes were determined. In addition, an algorithm for determining the possible combinations of product attribute states in the MATLAB program was developed. Additionally, the change in the current cost of the product considering the change in the quality level was estimated. The product cost changes were determined based on the actual cost of the product and the current product quality level. The method allows the determination of all combinations of values of state attributes of the product, such that it is possible to take appropriate improvement actions both in terms of quality and cost. The results from the method allow the prediction of product satisfaction for customers and they are favourable in terms of production cost. Therefore, it is possible to design the product in advance and support the producer in preparatory activities.

Opis:
The aim of the research was to identify the influence of environmental factors inherent in the alluvial and displaced sands of the study region on the growth of the Jack pine and the prospects for its cultivation. We found that the success of growth of Jack pine seedlings on sandy soils depends on a set of factors, which include the presence or absence, in the rhizosphere of sand, of humus impurities and genetic horizons of zonal soils, silty or loamy layers, soil density and composition of pine stands formed in the cultivation. On alluvial sands, sparse forests of Jack pine and Scots pine with a density of 0.3 units were formed. The yield of seeds from Jack pine cones was 1–2% higher than the normative values, and the mass of 1000 seeds was 50% higher. Jack pine seedlings grow according to I class of productivity on displaced sands, with an admixture of humus mass and remnants of genetic horizons of zonal soils at the root depth. In the rhizosphere of the stand, the roots of Jack pine seedlings occupied 78% of the mass of all roots that inhabited a metre-thick sand. Jack pine seedlings that fall under the canopy of Scots pine fall out of the plantations due to drying, which indicates their demand for light and appropriateness of growing Jack pine in solitary plantings or in mixed low-density plantations with Scots pine.
