Today, innovation is an important factor in socioeconomic development. Based on advanced engineering and manufacturing technologies, Industry 4.0 has a significant impact on technological innovation and offers valuable opportunities. Innovation activities allow companies to achieve many benefits in the short term, such as the introduction of new products to the market, the implication of new production technologies and, in the long term, the expansion of the market, meeting the exorbitant demands of customers, increasing productivity, and reducing costs, wastage, and production time. This study focuses on the issue of enterprise innovation and, in particular, on the innovative activities of industrial enterprises. This study aims to analyze the innovative activities of industrial enterprises and to identify the conditions that are conducive to undertaking pro-innovative activities. This study presents the theoretical basis for enterprise innovativeness. Secondary data relating to the issue of innovation in the industrial area were collected and analyzed. The activities undertaken made it possible to assess the current level of innovativeness, identify trends, and propose solutions that could support and increase the intensity of innovative activities. The results of this research can be used as a starting point for further deliberations on the creation of conditions supporting an increase in the innovativeness of Polish enterprises.

Purpose: The aim of the study was to modify the classic SCOR model to include a key area for manufacturing companies (quality control) and to propose a herarhical set of key performance indicators designed to measure the implementation of selected processes in line with reverse logistics and the idea of sustainable development. Design/methodology/approach: The study addresses the topics of indicator analysis and sustainability in the context of quality control implementation. The developed set of metrics was based on a modified SCOR supply chain model taking into account quality control and reverse logistics. Findings: Using the assumptions of the SCOR model in constructing a set of metrics allows it to be extended in the context of key supply chain links as well as defining hierarchical performance measurement. Research limitations/implications: A limitation of the proposed model was the lack of consideration of important business processes (sales, marketing, product development). The SCOR model lacks a link to the strategy and objectives of the supply chains considered. Further research will look at extending the model with missing elements and detailing the quality control process as envisaged by the SCOR model at level two adequately to the types of quality control occurring in the manufacturing space (input, inter-operational and final quality control). Practical implications: The proposed universal set of indicators and yardsticks is intended to enable its implication in manufacturing enterprises in the form of a traditional model (no recycling) or under conditions of reverse logistics application. The model makes it possible to compare the two options and choose the more efficient one. Social implications: The developed model for analysing the efficiency of one link in the supply chain allows the efficiency of reverse logistics to be monitored, which is closely related to the implication of the concept of sustainability in manufacturing enterprises. Originality/value: Modification of the SCOR supply chain model to include quality control and the return aspect in the production context. Based on which, a proprietary set of indicators was developed.

Aviation is one of the fastest-developing areas of transportation, and a strong aviation sector is important for a country's economic growth and competitiveness. As global flight activity increases, aviation authorities and international organizations must address new challenges to maintain high safety standards. This often means introducing new technologies and updating operational practices. The changes needed to meet these requirements will require adjustments to the skill sets that aviation professionals will be expected to have (on the ground and in the air). Therefore, having sufficient numbers of adequately trained aviation professionals is necessary, and hence, practical, experience-based training is essential in aviation education today. This study examines the current needs of aviation training and the limitations of traditional classroom-based teaching. Using a qualitative, comparative case-study approach, it analyses how flight laboratories are applied at two universities in Poland and Georgia, and how they provide students with direct experience with real aircraft and operational tasks. The results show flight labs enhance student projects, practical skills, and teaching methods in aviation.

With the increasing automation of production processes, there is a growing need for systematic monitoring of the safety and effectiveness of operational activities, which requires the use of appropriate performance indicators. The aim of the study was to develop a model for identifying key performance indicators (KPIs) for production and operational safety in an automated manufacturing environment. The research was based on a review of scientific literature, surveys, and nominal meetings with industrial safety experts. The identified KPIs were divided into three groups: preventive, monitoring, and result indicators. This approach enables multifaceted analyses covering preventive measures, ongoing monitoring, and evaluation of the effectiveness of implemented countermeasures. The proposed solution contributes to increasing employee safety, machine reliability, and the continuity of the entire enterprise. The verification of the proposed model confirmed its usefulness and practical applicability. The developed model can provide practical support for production engineers, safety specialists, and those responsible for system development in industrial organizations. Future research may focus on enriching the model with predictive solutions using advanced data analytics and machine learning methods.

An Information Security Management System (ISMS) compliant with ISO/IEC 27001 requires the development and implementation of an effective system to guarantee the protection of information from threats. The aim of the study was to propose a set of indicators to measure the effectiveness of SZBI safeguards in manufacturing companies. A model for analysing the effectiveness of the SMS was built, which requires significant involvement of the company's management. Systemic information security management produces the best results, as it involves treating as a whole all processes taking place in the organisation and is consistent with them. A way to measure the degree of information security was defined using indicator analysis and the application of key performance indicators (KPIs). The metrics addressed key areas such as malware protection, quality of passwords and authentication, updating systems and applications, data handling and training. The implementation of a set of indicators makes it possible to diagnose the security system currently in place and identify critical areas for improvement. The model and set of indicators presented in the study can be a helpful tool in maintaining an effective SMS and safeguarding the interests of manufacturing enterprises and their stakeholders.

The foundry industry is an important component of the economy on which other progressive industries depend. The reliability of the products it manufactures is determined by the technologies used, but, most importantly, it ensures the expected level of quality. The purpose of the article is to develop a synergistic quality-cost model for the improvement of casting products. The model is based on an integral methodological configuration that makes it possible to determine the level of relevance of the causes of casting nonconformity in the quality-cost context. The model integrates techniques such as the Pareto-Lorenz diagram, ranking, brainwriting, Ishikawa diagram, Likert rating scale, and matrix diagram. Verification of the method by its implication in the manufacturing process of a gearbox casting is performed. The model makes it possible to identify quality-cost relationships between key categories of problem causes and major product nonconformities. The main causes of the loss of quality stability of the analyzed product are found to be low quality of molding sand, poor technical condition of foundry equipment (too infrequent repairs and overhauls), and ineffective quality control. Carrying out the analysis made it possible to develop appropriate improvement measures. It is proposed to implement changes in the casting process, implement the TPM method, conduct periodic training, develop job instructions, implement a control system, and provide supervision of employees. Further research directions will concern the implications of the method within the other positions in the casting company and its development towards automation of analysis.

A market economy requires continuous improvement of products. The classic case is striving to meet customer expectations, i.e., ensuring product quality. However, in terms of sustainable development, it is also necessary to take actions that contribute to the protection of the natural environment and ensure a positive social impact. It is still a challenge. Therefore, the aim of the article is to develop a model for product improvement by considering the criteria of quality, environment, and social impact. The developed model is an original decision indicator, according to which prototypes of modified products are ranked according to their fulfillment of (i) expected quality, (ii) low environmental impact in the life cycle (LCA), and (iii) social responsibility. Based on the results of the model and the proposed decision indicator, it is possible to determine the direction of improvement of any product by assessing prototypes (product variants) in terms of their sustainable development. The model test is carried out for photovoltaic (PV) panels, popular in recent years, verified according to six prototypes and 15 sustainability criteria regarding their quality, environmental impact, and social responsibility. The test confirmed its effectiveness in the case of photovoltaic panels, but the proposed model can be successfully used to design or improve other products. This is supported by a developed original decision indicator supporting the making of multicriteria quality, environmental, and social decisions at the stage of designing new products or improving existing products.

Purpose: The aim of the article was to develop a QLCA framework model dedicated to the design and improvement of products, taking into account their quality (Q) and environmental impact in the life cycle (LCA). Design/methodology/approach: A review of the literature on the subject was conducted on studies from the Web of Science database. The thematic scope included the design and improvement of products, taking into account quality and environmental impact during the life cycle (LCA). Bibliometric and frequency techniques were used, including keyword analysis and citation of studies. Based on conclusions from the literature, approaches and methods for quality improvement, as well as the LCA methodology presented in the ISO 14040 standard, a QLCA framework model was developed. The model supports the prospective assessment of the quality and life cycle of the product and its prototypes in terms of sustainable development. Findings: It has been shown that there are no solutions that present the links between product life cycle assessment and product quality assessment, including preparing these assessments for product prototypes at the design and prototyping stage. Research limitations/implications: A QLCA framework model is presented, the proper form of which will be provided by future research. The framework conditions of the QLCA model were improved and expanded in order to find the most advantageous approach to achieving the highest quality product quality with the lowest possible negative environmental impact of this product in LCA in terms of its sustainable development. Practical implications: The QLCA framework model is the result of conceptual generalisation, and its assumptions were prepared for designers and R&D departments. The assumptions of the QLCA methodology can be used by management staff to make decisions about product improvement at the prototyping stage. Originality/value: A novelty is the QLCA framework model, which presents an original approach to product improvement at the prototyping stage, taking into account customer expectations regarding their quality and at the same time assessing the life cycle of these prototypes.

Measuring the performance of manufacturing enterprises is now a key component of developmental organizational management. Key performance indicators make it possible to determine the effectiveness of implemented changes, set new goals and confirm the reasonableness of incurred expenditures. However, a key difficulty is the selection of adequate metrics, which should correspond to strategic objectives and be tailored to the specifics of the enterprise. Therefore, the purpose of the study was to present a model for effective human resource management in manufacturing enterprises based on key performance indicators. The developed model makes it possible to justify the necessity and examine the relevance of decisions made and investments incurred. The originality of the study is due to the methodological nature and concerns the model used, which is the author's tool for supervising the development strategy of the organization taking into account the well-being of employees. The presented model can provide important support for managers shaping the personnel policy of the enterprise and carrying out tasks in the field of employer branding.

Sustainable product development is becoming essential to meet market, but also climate challenges. However, this is problematic mainly because of the need to make many complex decisions at the early stages of product development. Due to limited research in this area, the aim was to analyse the approach of companies to sustainable development when designing new products and improving products already on the market. This approach was considered according to the key aspects of sustainable product development, i.e.: quality (customer satisfaction with use), environment (impact in the life cycle), society (changes in the social environment) and cost. Pilot studies were conducted among manufacturing companies. These were surveys with a Likert scale, in which the following were verified: i) the frequency of actions taken regarding verified aspects, and ii) the degree to which these aspects were taken into account during product development. It was shown, for example, that the most frequently undertaken actions are those related to product costs, then quality, and slightly less often, environment and society. A similar phenomenon was observed in the case of the degree to which these aspects were taken into account in product development activities, which was additionally confirmed by the results of statistical analysis according to the sign test in the STATISTICA program. The results of the pilot studies confirmed the validity of conducting in-depth fundamental studies to determine clear rules and relationships that condition the consideration of key aspects within the framework of sustainable product development.

Sustainable development has caused companies to try to adapt their activities to changing customer expectations, but also to climate change. This poses a particular challenge for SMEs from developing countries. Therefore, the objective of the investigation was to analyse the qualitative-environmental aspects of the improvement of the products in SMEs from the countries of the Visegrad Group (V4). The results analysed constituted a research sample of 379 companies in the electrical machinery industry (machine processing industry), which were obtained in the period from March to September 2023 through a targeted survey. The area of analysis included, e.g.: (i) environmental issues of selected areas of activity, (ii) measures of environmental activity, and (iii) selected qualitative-environmental aspects. Analyses of the research results were carried out using quantitative and qualitative analyses, including comparative analyses, e.g. regarding the implementation status of ISO 14001, EMAS, and ISO 9001. These techniques were used: word cloud, ANOVA test and Mann Whitney U test at the significance level of α=0.05. It has been shown that SMEs in V4 countries focus their activities on improving products to improve their quality rather than limiting their negative environmental impact. Originality of the research is the identification of significant differences in the qualitative-environmental aspects undertaken when SMEs from V4 countries. Research results may contribute to the development activities more effective and coherent in the V4 countries, to achieve a stable and competitive advantage on the market as part of the qualitative and environmental improvement of the products. The research results and the conclusions drawn from them can be used by scientists and practitioners to shape the target states of enterprises in the period of increasing involvement in proecological ideas.

The paper presents a novel MCDM model aimed at enhancing satisfactory quality-environmental decisions in product development. The model integrates FAHP, FTOPSIS, Pareto–Lorenz and global sensitivity analyses. It enables to study products with respect to quality level, environmental impact throughout its life cycle and simultaneous consideration on quality level and environmental impact. Results of the research on the example of a smartphone demonstrate that the model successfully identified specific criteria for improvement, offering a valuable tool for enhancing customer satisfaction and promoting environmentally friendly product development. The originality of the research lies in the calculation of the average weights of product criteria with triangular fuzzy numbers, based on the principles of fuzzy logic and FAHP. As a compact, ready-to-use solution, our innovative MCDM model can be employed by organizations to enhance the quality and environmental impact of their products.

Purpose: The main purpose of this article is to present modern possibilities for the reproduction of a machine element. If there are no replacements for the damaged part, and there is no technical documentation, then the only options is to use reverse engineering (RE) methods to reproduce it. Design/methodology/approach: On the example of a damaged gear, the process of measuring the wheel and manufacturing a physical model using 3D printing. An additional step has been added to the classic reverse engineering process to modify the model to improve its strength. Findings: Strength analysis was carried out in the Abaqus program using the finite element method (FEM). Based on the results obtained, it was proposed to change the tooth profile of the gear, which will improve its durability. Research limitations/implications: An extension of the proposed scheme may be a modification of the production process in order to implement the reverse engineering method to the serial production of machine elements. Practical implications: The use of a modified reverse engineering (RE) process will not only allow the components to be reproduced but will also allow extended uptime of the components, and this will reduce production costs. Originality/value: The proposed new reverse engineering process can be successfully used to reconstruct machine components with even very complex shapes. The digital model obtained as a result of scanning has been used to improve the geometry of the toothed rim, but it can be successfully used for other analyses, research, or calculations.

Purpose: The purpose of the study was to analyze the importance of the issue and the level of sustainable development in the context of the functioning of Poland and Slovakia against the background of the European Union, based on a system of indicators, and to analyze the level of implementation of selected sustainable development goals by these countries. Design/methodology/approach: The research process was based on the diagnostic survey method. The techniques used for data collection were content analysis and desk research. The study covered the years 2000-2021. Findings: Both in theory and in practice, a problem has been recognized, namely that the surveillance methods developed are fraught with various disadvantages (e.g., standardization or uniformity of data for all EU countries). Within the framework of each of the examined indicators (from the area of SDG7, SDG8, SDG9), Poland showed a rise in the ranking of EU member states between 2000 and 2021. Slovakia, on the other hand, only in relation to the indicator of ross domestic expenditure on R&D by sector (SDG9) showed a decline in placement. Research limitations/implications: A limitation of the study's implementation is the potential constraints on the availability of the data needed to calculate indicators to monitor the degree to which the Sustainable Development Goals are being met. Practical implications: The results of the research will positively influence the planning of further activities by both the analyzed countries, Poland and Slovakia. The results of the research provide constructive information that may prove useful for the development of future strategic plans related to the implementation of the goals of the concept of sustainable development. Originality/value: The study fills a research gap in the field of comparative analysis of selected spectra of Poland and Slovakia against the background of the European Union in the context of the implementation of sustainable development goals (Development Agenda 2030).

The state of the technical infrastructure determines the degree to which the quality requirements of products are met and has a significant impact on occupational safety. The purpose of this study is to build a universal model for supporting quality management, which allows the effective implementation of a wide-ranging research path supporting the evaluation of the relationship between the degree of modernity of product processing technology and the quality of the final product and the level of occupational safety. The developed model is verified by its implementation in one of the turning stations. A practical test of the quality management support model confirms that the practice of conducting analyzes of the level of modernity of infrastructure with its application contributed to identifying critical machine components, examining factors affecting the quality of technological operations, reducing uncertainty and the risk of risky events, and conducting activities in line with the concept of continuous improvement. The course of action detailed in the model makes it possible to determine the relationships that exist between key categories of factors and critical product defects, and accidents and near-misses. This allows for the proposal of adequate improvement measures. Further studies concern the implementation of the model at other workstations in the foundry company.
