Purchasing groups are multi-entity organisations that operate in practically every sector. Their greatest role is to improve the financial situation of small and medium enterprises (SMEs). In the ...case of enterprises operating in the sectors that are just developing, especially those belonging to SMEs, it is particularly difficult to obtain favourable financial results. In Poland, such sectors include, among others, renewable energy, which is slowly developing, but has not yet reached the size set in climate policy. The purpose of the paper is to present how functioning under group purchasing organisations (GPOs) affects the profitability of companies related to the renewable energy sector. For the example of the largest industry purchasing groups, the analysis showed that high profitability results were achieved by enterprises operating in them compared to entities operating independently in the market. In total, 71 enterprises operating in the sector related to the renewable energy sector in Poland were analysed. The enterprises were divided into units operating in the purchasing groups of 46 enterprises, and those that operate independently in the market of 25 enterprises. The research period covered the years 2016–2019. The analysis showed that the scale effect allowed companies to increase profits and had a positive effect on their financial liquidity. The research proved that in the case of commercial enterprises operating in the sector related to renewable energy, functioning within the industry purchasing group allowed high profitability and financial liquidity. There is a dependency that the liquidity increases with a growth in profitability.
The aim of this publication was determining the impact of implementation of the ISO 14001 standard requirements on creating sustainable supply chains in the textile industry. The research process ...included the development of research tools such as questionnaires. Surveys of anonymous nature were sent by e-mail to top management representatives organizations operating in the south-eastern Poland and Slovakia who hold a certified quality management system according to ISO 14001. The research process carried out as well as the analysis of the obtained results allowed to respond to the research questions. As a resoult it can be stated that the ISO 14001 standard is an instrument that has a noticeable impact on improving the concept of sustainable supply chain management (SSCM) in the textile industry.
The purpose of this publication is to characterize the philosophy of TQM guidelines and show how this implementation can improve logistics operations. The article is based on an analysis of the ...literature on the issues of quality in logistics. It is based upon an analysis of key publications on the definition, implementation and application of TQM in logistics. Moreover, the research process was conducted on the group of 31 of Polish and German entrepreneurs. The result of the work is to highlight the areas of logistics management in which the implementation of modern quality management systems can be crucial for joint development. The implementation of TQM philosophy promotes the integration of the supply chain, builds positive relationships with customers, improves the level of logistics customer service and develops logistics subsystems. You can also formulate a thesis that high quality products and logistics processes are the foundation of supply chain management strategies.
In recent decades, the forest industry has been growingly expanded due to economic conditions, climate changes, environmental and energy policies, and intense demand changes. Thus, appropriate ...planning is required to improve this industry. To achieve economic, social and environmental goals, a supply chain network is designed based on a multi-period and multi-product Mixed-Integer Non-Linear Programming (MINLP) model in which the objective is to maximize the profit, minimize detrimental environmental effects, improve social effects, and minimize the number of lost demands. In addition, to improve forest industry planning, strategic and tactical decisions have been implemented throughout the supply chain for all facilities, suppliers and machinery. These decisions significantly help to improve processes and product flows and to meet customers’ needs. In addition, because of the presence of uncertainty in some parameters, the proposed model was formulated and optimized under uncertainty using the hybrid robust possibilistic programming (HRPP-II) approach. The ε-constraint technique was used to solve the multi-objective model, and the Lagrangian relaxation (LR) method was utilized to solve the model of more complex dimensions. A case study in Northern Iran was conducted to assess the efficiency of the suggested approach. Finally, a sensitivity analysis was performed to determine the impact of important parameters on objective functions. The results of this study show that increasing the working hours of machines instead of increasing their number, increasing the capacity of some facilities instead of establishing new facilities and expanding the transport fleet has a significant impact on achieving predetermined goals.
The need to evaluate suppliers from the perspective of risk analysis by purchasing companies is increasing. Such evaluation of suppliers is conducted primarily by production companies with ...implemented quality (QMS), environmental (EMS), health and safety management systems (H&SMS), as well as Toyota Production System (TPS). This article aims to examine latent factors for suppliers’ evaluation and to describe the intensity of these factors by the implemented management system. The article provides the results of empirical research conducted with the computer-assisted telephone interviewing (CATI) technique in 151 medium and large manufacturing companies operating in Poland. The risk was classified into three main groups to deepen the research process: management system risks, environment risks, and process risks. This allowed for the formulation of some original conclusions. The results showed that companies implementing standardized management systems take the issue of risk analysis and management more seriously than organizations that do not implement such systems. The research also highlighted the differences in the perception of risk caused by implementing various management systems. The study also found that the industry and business profile specificity also affect the risk assessment in cooperation with suppliers.

Purpose - The purpose of this paper is to ask one question. How the implementation of the requirements of ISO 9001 system affects the costs of running the business? Design/methodology/approach - The ...research covered time from 2006 to 2011 and was an attempt to assess the impact of the maintenance of the ISO 9001 Quality Management System on the costs of small and medium sized business organizations. The main objective was the selection of right research subjects that would allow the formulation of the most reliable and statistically valid conclusions. For this purpose we obtained permissions to conduct research in organizations characterized by comparable futures such as size, industry, type of business and strategy. Findings - The study shows that the costs associated with the implementation and maintenance of the Quality Management System standard is still too high, and effectively discourages representatives of small and medium-sized commercial organizations from implementing ISO 9001 system.
Working capital is designed to provide enterprises with financial security. Its level depends on the strategy of managing individual elements of working capital. An appropriate management strategy ...allows companies to obtain added working capital. Working capital management is a difficult process as it concerns both current assets and current liabilities. Therefore, company managers are constantly looking for solutions, methods and tools that will help them to manage their working capital. A quality management system is the one that facilitates control over the management of individual elements that create net working capital. The introduction of appropriate procedures derived from quality management systems in specific areas is a great support for creating a positive net working capital. The aim of this paper is to show how the introduction of quality management systems can positively affect the level of working capital. The article presents how quality management systems allow for optimizing the level of individual components, creating a positive net working capital. The research was carried out on a group of 102 Polish small trading companies operating in the same industry. The enterprises were divided into two groups of companies applying the quality management system and of those that did not use such systems. Based on the financial statements for the years 2017-2019 and by means of appropriately selected financial ratios, an analysis of the impact of quality management systems on net working capital was carried out. The results in some areas of management of individual components of net working capital in different groups of enterprises were compared. The research was carried out with the application of appropriate statistical methods. The analysis showed that enterprises using quality management systems managed working capital more efficiently. In the literature, the subject of the impact of quality management systems on working capital is not popular. This paper may be a source for further, extended research and considerations regarding the impact of quality management on the level of working capital in enterprises.
Fused deposition modeling (FDM) is the most economical additive manufacturing (AM) technology available for fabricating complex part geometries. However, the involvement of numerous control process ...parameters and dimensional instabilities are challenges of FDM. Therefore, this study investigated the effect of 3D printing parameters on dimensional deviations, including the length, width, height, and angle of polylactic acid (PLA) printed parts. The selected printing parameters include layer height, number of perimeters, infill density, infill angle, print speed, nozzle temperature, bed temperature, and print orientation. Three-level definitive screening design (DSD) was used to plan experimental runs. The results revealed that infill density is the most consequential parameter for length and width deviation, while layer height is significant for angle and height deviation. The regression models developed for the four responses are non-linear quadratic. The optimal results are obtained considering the integrated approach of desirability and weighted aggregated sum product assessment (WASPAS). The optimal results include a layer height of 0.1 mm, a total of six perimeters, an infill density of 20%, a fill angle of 90°, a print speed of 70 mm/s, a nozzle temperature of 220 °C, a bed temperature of 70 °C, and a print orientation of 90°. The current study provides a guideline to fabricate assistive devices, such as hand and foot orthoses, that require high dimensional accuracies.
Purpose: The main purpose of the paper was to determine the impact of an implementation of the quality management system according to ISO 9001 on the improvement of processes related to the ...management of liabilities to suppliers.Methodology/Approach: The research covered 38 Polish small trading enterprises operating in two group purchasing organizations. The research period concerned the years 2014-2016. The surveyed enterprises were divided into those that implemented standardized quality management systems (10 organizations) and the ones that do not use such solutions (28 organizations). Next, the analyses were made and the results obtained by enterprises associated in particular groups were compared.Findings: The obtained results confirm that more effective management of liabilities towards suppliers can be observed in enterprises applying appropriate system procedures. This group includes long-term liabilities and the turnover ratio of short-term liabilities in days achieves lower results than results for enterprises that did not introduce standardized quality management systems.Research Limitation/implication: Due to a small research sample, the obtained results can only be considered as an introduction to further research and deliberations.Originality/Value of paper: The considerations discussed in this article concern a relatively rarely discussed subject matter in the literature.
The move towards a new Circular Economy (CE) economic model has been advocated and supported in Portugal, however, there is limited research on this topic. To address this gap, a quantitative ...research based on an online survey was carried out among 99 Portuguese organizations, encompassing a wide range of sectors and sizes. The results show that CE is regarded as a strategic and relevant issue for profitability and value creation. Furthermore, the perception that it requires the adoption of new business models in addition to the classical “reduce, reuse and recycle” approach is growing. Moreover, based on the hypotheses raised, results suggest that the level of CE adoption is positively impacted by the status of the EMS (Environmental Management System) certification and the willingness to improve the environmental performance and achieve a sustainable business model. However, CE activities are still relatively modest and a friendlier context (fiscal, legal, organizational, etc.) and the stronger support from supply chain agents and consumers are required. Future research should focus on how to design and shape the transition from a linear to a CE economy and to ascertain if the positive attitude towards CE is materialized in changing the way business is done.
