    Opis:
    Meeting the required quality level of products taking into account customer requirements is the essence of thriving enterprises. In this context, it is necessary to make decisions that take into account mentioned the quality level but also the cost aspect relevant to both customer and producer. It was concluded that it is possible to make analyse in which connected the quality level with the cost aspect will condition the make the best choice. Therefore, the aim of work was to propose the pro-quality method of choice by using the ordered fuzzy numbers connected with cost-quality analysis (AKJ). The subject of the study were machines used in pad printing technique, so-called pad print, which choice resulted from their problematic choice to specific and often variable working conditions. As part of the method by using ordered fuzzy numbers, using the Fuzzy TOPSIS method (The Technique for Order of Preference by Similarity to Ideal Solution) the most favorable machine by quality was determined. Subsequently, a pro-quality machine choice was made, and this choice combined the obtained quality level with the purchase cost through the use of cost-quality analysis. The proposed method is some kind of new approach to making the best decision, where the aspect of quality with the cost was connected. Therefore, the proposed method can be used to solve different types of decision problems in production and services enterprises.

    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 competitive and turbulent environment generates the need to use various techniques to determine the level of product quality. In this aim, it is necessary to determine the direction of improvement attributes and function of the product based on customer requirements, which are usually uncertain. Therefore, the aim of the article is to propose the technique to improve the product quality by precisely determine the customers' requirements and the importance of the quality parameters for the current attributes of the product. This technique is a combination of methods i.e.: the QFD method (Quality Function Deployment) with the GRA method (Grey Relational Analysis). Using the QFD method, customer requirements were translated into technical features of the product. In turn, using the GRA method the imprecise customers' requirements were reduced and the importance of quality parameters was determined in a more accurate way. A test of a combination of the QFD and GRA methods for the household vacuum cleaner was made. The originality of the article is ensuring a precise study of the current attributes of the product from the point of customer satisfaction.

    Opis:
    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:
    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.

    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:
    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.

    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.
