Opis:
Machinery faults are a problem that incorrectly diagnosed may result in the increase of waste. The fault mentioned in the article was identified at an opencast facility located in Podkarpacie. The purpose of the study was to analyse the defect identified on the excavator arm using quality management techniques. These techniques were the Ishikawa diagram and the 5Why method. In the plant, unit faults on various types of machines were detected. The fracture on the excavator arm was identified, however, the cause of the problem was not known. Potential causes of the fault and the main cause of the problem (material fatigue) were detected using the Ishikawa diagram. The root cause of the material fatigue, the long-term and repetitive operation of the excavator during the excavation of the deposit, was identified by the 5Why method. The proposed processes can be used to identify the root causes of various faults both in the mining industry as well as production and service plants.

Opis:
The research of railway track surfaces is aimed at improving the quality of railway infrastructure and providing the chance of improving the safety of driving. Therefore, it is advisable to constantly monitor track surface, but the research itself is not innovative because it is based on a known procedure. The crucial element are the techniques that allow to delve into the sources of problems. The aim of the article is to use the selected instruments of quality management to analyze the causes of track twist at high (180 km/h) speed of driving. The analysis of the causes of track twist was done on the basis of results from the measurement of one kilometer track section of the Krakow Glowny - Medyka route, which was made by using the TEC measuring device in April 2018. It was inferred that it is impossible to reach 180 km/h without track twist. In order to identify the causes of track twist it was proposed to use the selected sequence of quality management instruments, i.e.: brainstorming, Ishikawa diagram and the 5Why method. The identified causes of track twist include the abrasion of rail, scratches and exploitation point. The analysis and conclusions drawn from it may be useful in the analysis of other problems in railway transport as well as production and service industries.

Opis:
The analyses of the nonconformity of products are made in order to achieve the desired level of their quality. This is also the case in the analyzed enterprise located in south-eastern Poland. Due to production character in this enterprise to identify the incompatibilities of products the non-destructive tests are used. In the current approach to quality after identified the nonconformities the cause her arise were determined, it was noted in order to use by statistical analyzes. Unfortunately, no deeper qualitative analyzes were made which could specify the source of its creation. Therefore, it was considered that it is necessary to propose to use (near current actions according to nondestructive tests) the sequence of quality management instruments. In order to improve the quality control actions, the sequence of techniques which complement each other, i.e. non-destructive tests, Ishikawa diagram and 5Why method, was proposed. To demonstrate the effectiveness of the proposed sequence, the rear cover of the bearing turbine was selected as the subject of the analysis. The choice was conditioned by the unit character of production, which till now was discouraged a detailed analysis of sources of nonconformities. After analyzed the product with used the fluorescent method the nonconformities were identified on the rear cover of the bearing turbine, which was the porosity cluster. In order to identify the causes these nonconformities the Ishikawa diagram was drawn up. Next, the selected main causes (i.e. supplier of the product and nonconformities created during the production of the product) were analyzed the 5Why method in order to identify the source cause of the problem. In this case, it was the nonconformity material from the supplier. The proposed sequence, which uses the minimal resources let to show the wide range of information, which should be used to the improvement of quality. The presented the set of activities can be practised in each of the enterprises to analyze quality problems in order to identify the nonconformities and their causes.

Opis:
An occupational risk assessment is one of the main processes to assure a safe and healthy workplace. It was shown, that this process is particularly important in the cause of industrial enterprises, in which the number of accidents is the largest. In these enterprises, one of the most often practiced methods is the PN-N-18002 method. However, it was concluded this method has some limitations. They concern the way of assessing the risks in the traditional number scale, which is less precise than the fuzzy triangular number (using in FAHP). Therefore, the aim is to improve the process of assessment in industrial enterprises by integrated the PN-N-18002 method with the FAHP method (Fuzzy Analytic Hierarchy Process). The test of the proposed method was made for three machine operator positions used to aggregate extraction in one of the Podkarpacie enterprises. These positions were: loader operator (Ł-34), digger operator (CAT 323), dredge operator (300/250 KREBS 10/8). The concept of the method was to identify in a precise way what is the greatest extent danger to the operators of these workplaces. It was shown, that it is the work at height. It was concluded, that this method can be practice to risk assessment of other workplaces, among others from industrial enterprises. The originality is the integrated risk assessment method (PN-N-18002) with the fuzzy multicriteria decision method (FAHP) as part of achieving the precise results of risk assessment.

Opis:
Emisja gazów cieplarnianych (w tym CO2), głównie w nawiązaniu do sektora energetycznoprzemysłowego, generuje negatywne zmiany w środowisku naturalnym. Dlatego, aby podejmować skuteczne działania mające na celu redukcję tych emisji, ważne jest właściwe ich analizowanie. W związku z tym celem artykułu było zaproponowanie wykorzystania techniki do analizy emisji zanieczyszczeń, która uwzględni jednocześnie wielkość oraz szkodliwość wytwarzanych emisji. Techniką tą był rozmyty analityczny proces hierarchiczny (FAHP, Fuzzy Analytic Hierarchy Process) oraz metoda TOPSIS (Technique for Order Preference by Similarity to an Ideal Solution). Proponowaną technikę przetestowano na aktualnych, dostępnych danych statystycznych z Głównego Urzędu Statystycznego, dotyczących emisji zanieczyszczeń powietrza w Polsce w roku 2018 według sekcji PKD. W ramach przetestowania techniki określono, który z zakładów szczególnie uciążliwych dla czystości powietrza według sekcji PKD ma największy wpływ na zanieczyszczenie powietrza, z jednoczesnym uwzględnieniem wielkości i szkodliwości wytwarzanych emisji. Mimo że uzyskane wyniki wynikają z subiektywnych ocen podmiotu stosującego technikę, wykazano, że technika ta umożliwia przeanalizowanie emisji zanieczyszczeń z jednoczesnym uwzględnieniem wielkości i szkodliwości emisji. Z kolei subiektywizm ocen po części zredukowano przez rozmytą skalę Saaty’ego. Stosując proponowaną technikę FAHP oraz metodę TOPSIS, wykazano, że możliwe jest dokonanie subiektywnej oceny szkodliwości emisji zanieczyszczeń oraz zintegrowanie ich z rzeczywistymi danymi, np. z danymi GUS. W związku z tym proponowana technika jest nowym podejściem do analizy emisji zanieczyszczeń, dlatego też jej zastosowanie może usprawnić proces decyzyjny w ramach ograniczania emisji, a tym dwutlenku węgla, którego redukcja, jak wskazano, jest aktualnym problemem na skalę globalną.
Greenhouse gas emissions (in it CO2), mainly with reference to the energy and industrial sector, generate negative changes in the natural environment. Therefore, to make effective actions in order to reduce this emission, it is important to analyze them properly. Therefore, the aim of the article was to propose using a technique to analyze the emissions of pollutants, included at the same time the size and harmfulness of emissions produced. This technique was a fuzzy analytic hierarchy process (FAHP, Fuzzy Analytic Hierarchy Process) and TOPSIS method (Technique for Order Preference by Similarity to an Ideal Solution). The proposed technique was tested on current, available statistic data from the Central Statistical Office, on emissions of air pollutants in Poland in the 2018 year, according to PKD section. As part of testing the technique, it was specified which of plants according to PKD section has the biggest influence in pollutant the air, with simultaneous consideration of the size and harmfulness of generated emissions. Although that obtained results arise from subjective assessments of the entity using the technique, it was shown that this technique allows analyzed the pollution emissions, by including at the same time the size and harmfulness of emission. In turn of the subjectivity of assessments partly was reduced by the fuzzy Saaty scale. Using the proposed FAHP technique and the TOPSIS method, it has been shown that it is possible to perform a subjective assessment of the harmfulness of pollutant emissions and to integrate them with actual data, e.g. with data from the Central Statistical Office. Therefore, the proposed technique is a new approach to analyse emissions pollutions, in it CO2, whose reduction, as indicated, is a current global problem.

Opis:
Identifying inconsistencies and taking adequate actions to eliminate them is an effective way to improve the quality of products. Casting products are one of the items commonly manufactured in the foundry industry. Determining their quality becomes problematic due to a large number of factors affecting them during production which can generate various types of incompatibilities. The problem with a large number of incompatibilities of castings arose in a company in the southern part of Poland. The aim of the research was to diagnose the state of a batch of castings of industrial robot arm parts and to precisely determine the most important reasons for the occurrence of unworthiness, in relation to which appropriate preventive measures could significantly contribute to the reduction of the number of non-compliant castings and hence, waste. The analysis of incompatibilities occurring in the casting using the Pareto-Lorenz method and the ABC method allowed indication of the most important (in terms of frequency and severity) incompatibility of castings - gas porosity. Continuing the analysis of the problem by means of a brainstorming session and organizing ideas via the Ishikawa diagram made it possible to identify the key cause of the problem, which was the inadequately prepared (wet) core of the casting mold.

Purpose: The aim of the study is to analyze environmental awareness among employees of companies producing plastics, and subsequently to draw conclusions about the level of their pro-environmental awareness. The motive for the implementation of pro-environmental awareness research in plastics-producing plants was their harmful impact on the environment. Design/methodology/approach: The research was a survey that was carried out among 44 workers of plastics enterprises located in south-eastern Poland in the first quarter of 2018. During the selection of companies for research, it was included: their location (south-eastern Poland), long-term operation (more than 30 years), the same type of activity (production of plastics), and whether pro-environmental activities were practiced. Findings: It was concluded that the level of awareness of the employees of plastic industry employees was on a low level. Research limitations/implications: The research sample is only a preliminary sample. It is planned to obtain data from a larger number of companies and verify the data. Practical implications: Enterprises should focus on meeting customer needs and maintaining high-quality products, but taking into account pro-environmental measures that should be a priority. This is possible if pro-environmental awareness is continually shaped. Social implications: The pro-environmental awareness is small among employees from the enterprises, in which pro-environmental actions were not practiced. Employees do not know how the processes are carried out in the company and whether they have any impact on the natural environment. Additionally, the employees of companies not used pro-environmental activities are unaware of the threats resulting from the activities of their company and do not know that other companies about the same activities already apply such activities. Originality/value: These results will allow better decisions in the context of sustainability and improvement actions to achieve a higher level of awareness among the plastic production companies' employees.

Opis:
Analysis of the incompatibilities occurring in an organization relies on identifying the problem and then applying the appropriate corrective and improvement actions. It is possible by using appropriate instruments of quality management and, basically, their sequence, which is a modern way of solving the problem, and it enables the improvement of functioning of an enterprise. Therefore, it is advisable to select an appropriate group of quality management instruments and use them in the appropriate sequence, because then they are complete and lead to full analysis and conclusions adequate to the problem. The aim of the article is to analyze the correlation and influence of the selected factors on the incompatibilities in selected processes, i.e. the production process of furniture fronts and furniture in general. Moreover, the idea is to use the appropriate sequence of instruments of quality management to solve various types of incompatibilities. The analysis was made at a company where a lot of different kinds of incompatibilities in processes were identified within 9 months. It was important to solve the problem for this enterprise because it was generating relatively large financial losses, and the lack of identified causes of the problem precluded taking preventive actions and developing the enterprise. After the initial analysis of the processes and problems, it was decided to use the correlation analysis, the Pareto-Lorenz diagram, the 5W2H method, the Ishikawa diagram and the 5Why method. The methodology and conclusions drawn from the analysis may be useful in solving complex problems at other production and service enterprises.

The analysis of the problem of the mechanical damage was made for a company manufacturing furniture and furniture fronts. From January to September the company identified 285 pieces of mechanically damaged products. The management of the company wanted to identify the source of the incompatibility; therefore, it was purposeful to analyse the problem of the mechanical damage using the sequence of the selected instruments of the quality management that enable this. Additionally, until now the company has not used the instruments of the quality managements to analyse the problems involving nonconformity, so it was important to show the company their practical use. The aim was to analyse the problem of the occurrence of the mechanical damage in fronts and furniture and to identify the root cause of the problem. Also to show the effective use of the sequence of the quality management instruments (i.e. 52WH method, Pareto-Lorenz diagram, Ishikawa diagram, 5Why method) to solve the problem of incompatibility. It was concluded that the root cause of the mechanical damage of fronts and furniture was the lack of management knowledge and awareness of the need to implement visualization principles in the company. The analysis and the proposed improvement actions may be practiced in other companies from both the production and service industries.

Opis:
Lean Manufacturing is a profound system designed to enhance every manufacturing industry's efficiency by reducing waste through internationally recognized tools and techniques. Enterprises of all sizes and industries strive to adopt Lean Manufacturing (LM) concepts to maximize their resources, such as personnel, facilities, materials, and operating schedules, to be economically effective. There are several models for implementing Lean philosophy in enterprises. The conducted research is aimed at reviewing and conceptualizing the LM system implementation framework in the enterprises in Central and Eastern Europe. The analysis was based on the results of surveys conducted in micro, small, medium and large enterprises, mainly in production, trade and service organizations. As a result, among others, the main premises, methods and benefits of implementing the LM system, thus identifying the specificity of the concept in the context of the size of enterprises and the industry from which they come, were indicated. The originality is the analysis of the effectiveness, efficiency and productivity of Lean activities, distinguishing the size of the organization from the group of micro, small, medium and large organizations (MSME). The research results show that the LM implementation model in enterprises from Central and Eastern Europe is based on the Shingo model.
Produkcja szczupła to rozbudowany system zaprojektowany w celu zwiększenia wydajności każdej branży produkcyjnej poprzez redukcję odpadów dzięki uznanym na arenie międzynarodowej narzędziom i technikom. Przedsiębiorstwa niezależnie od wielkości i branży starają się przyjąć koncepcje Lean Manufacturing (LM) , aby zmaksymalizować swoje zasoby, takie jak personel, obiekty, materiały i harmonogramy działania, aby były ekonomicznie efektywne. Istnieje kilka modeli implementacji filozofii Lean w przedsiębiorstwach. Realizowane badania mają na celu dokonanie przeglądu i konceptualizacji ram wdrożeń systemu LM w przedsiębiorstwach w Europie ŚrodkowoWschodniej. Analizę oparto na wynikach z badań ankietowych przeprowadzonych w mikro, małych, średnich i dużych przedsiębiorstwach, głównie w organizacjach produkcyjnych, handlowych i usługowych. W rezultacie wyłoniono m. in. główne przesłanki, sposoby oraz korzyści z wdrożeń systemu LM identyfikując dzięki temu specyfiki koncepcji w kontekście wielkości przedsiębiorstw oraz branży z których pochodzą. Oryginalnością jest przeanalizowanie skuteczności, efektywności oraz wydajności działań Lean w rozróżnieniu na wielkość organizacji z grupy mikro, małych, średnich i dużych organizacji (MSME). Wyniki badań skazują że model wdrożenia LM w przedsiębiorstwach z Europie Środkowo-Wschodniej oparty jest na modelu Shingo.

Opis:
Purpose: The purpose was to develop an approach to predict product quality considering current customers' expectations. Design/methodology/approach: The approach includes integrated techniques, i.e.: SMART(-ER) method, a questionnaire with the Likert scale, brainstorming (B&M), WSM method, and Naïve Bayes Classifier. This approach refers to obtaining customers' expectations for satisfaction from the current quality of products and the importance of these criteria. Based on the satisfaction of customers, the quality of the product was estimated and classified. Then, the quality of the product was predicted for current customers. Findings: It was shown that it is possible to predict product quality based on current customer expectations, and so based on the current existing product. Research limitations/implications: The proposed approach does not include the possibilities of determining the expected quality of the product. The approach focuses on predicting customers' satisfaction with the current quality of the product. Therefore, if there is a need for improvement actions, further analyzes should be carried out to determine which criteria should be modified and how. Practical implications: The presented approach can be used for any product. Therefore, it is a useful tool for any kind of organization, which strives to meet customer satisfaction. Despite the possibility to predict the quality of the product, the proposed approach can indicate at an early stage to the organization that it is necessary to make improvement actions. Social implications: It is possible to reduce the waste of resources by predicting that improvement actions are necessary. Moreover, the approach supports an entity (e.g., expert, enterprise, interested parties) in predicting current customers' satisfaction. Originality/value: Originality is predicting product quality based on current customers' expectations. A new combination of quality management techniques, decision support, and machine learning was implemented.

The idea of the concept depends on determining the product that will be satisfactory for the customer, i.e., satisfied simultaneously in turn of quality and cost of purchase. A questionnaire is used to obtain customer expectations. Then, according to the DEMATEL method, the relations between these criteria are determined. Next, the weights (importance) of the criteria are estimated by arithmetic average. Additionally, according to the Likert scale, these criteria' initial quality (customer satisfaction) is assessed. Based on these, the quality of the product is estimated by using the WSM method. The calculated product quality is combined with the real cost of its purchase in the qualitative-cost analysis (AKJ). According to the results of the qualitative-cost analysis, the expected product of the customer is predicted. This process is supported by the Relative States Scale. The proposed conception can be used to verify any product. Therefore, it can be useful for different entities offering products to the customer and striving to meet their expectations (satisfaction). The originality is the simultaneous prediction of the expected level of product quality and the cost of its purchase and the ability to determine customer satisfaction at this qualitative-cost level.
Głównym problemem współczesnych przedsiębiorców jest odpowiednie rozpoznanie oczekiwań klienta na podstawie aktualnych produktów. Celem opracowania jest zaproponowanie koncepcji modelu do przewidywania poziomu jakościowo-kosztowego produktu według modyfikacji produktu. Idea koncepcji polega na określeniu satysfakcjonującego dla klienta produktu, który będzie jednocześnie zadawalający pod względem jakości i kosztu jego zakupu. Kwestionariusz wykorzystuje się do pozyskania oczekiwań klienta. Kolejno, według metody DAMATEL określane są relacje pomiędzy kryteriami. Następnie stosując średnią arytmetyczną szacowane są wagi (ważność) kryteriów. Dodatkowo, według skali Likerta oceniana jest wstępna jakość (satysfakcja klienta) z tych kryteriów. Na ich podstawie szacowana jest jakość produktu zgodnie z metodą WSM. Obliczona jakość produktu łączona jest z rzeczywistym kosztem ich zakupu w analizie kosztowo-jakościowej (AKJ). Według poziomu kosztowo-jakościowego przewidywany jest produkt oczekiwany przez klienta. Wybór wspierany jest skalą stanów względnych. Proponowana koncepcja może być stosowana do weryfikacji dowolnych produktów. Dlatego może być użyteczną dla różnych podmiotów oferujących produkty klientowi i dążących do spełnienia ich oczekiwań (satysfakcji). Oryginalnością jest jednoczesne przewidzenie oczekiwanego poziomu jakości produktu i kosztu jego zakupu oraz możliwość określenia satysfakcji klienta z tego poziomu jakościowo-kosztowego.

Opis:
Purpose: The basic purpose of research was to determine the causes of making the decision that manufacturers on their way to improve the quality of their products. Design/methodology/approach: The research method applied in article is mainly standardized survey research making based on survey conducted in contact and remote way conducted in 78 enterprises in south-eastern Poland. The research process also accompanied analysis of thesource documentation. Findings: It was concluded that decision during improving quality of the product were making mainly in simultaneously with considering customers' requirements of the customers about the quality of the products and the impact of products on the natural environment. Research limitations/implications: Most of the verified enterprises from SMEs are tried integrating qualitative-environmental actions as part of improving the quality of products. This is a favorable condition for further research, so that it is possible to adjust the quality and environmental approach when improving the quality of products in SMEs. Practical implications: Discussion of the results of research have a series of practical implications mainly for product management staff. Especially in organizations that designed new products or also in significant modification of these products. Social implications: Building awareness improves not only quality of products, but also simultaneously in line with sustainable development, including in improving environmental aspects. Originality/value: The article has cognitive value for development of knowledge, science, quality, and environmental in the area of management of products.

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.
