Background: Today, companies operate in an environment that is significantly affected by the forces of transformational changes, which create problems for logistics. Reverse logistics is a relatively new topic for businesses. Therefore, the purpose of this article is to study the relationship between reverse logistics and competitiveness, economic performance, the environment, and society. Methods: The research methodology includes general scientific and special methods, such as synthesis and analysis, logical generalization, correlation and regression analysis. The hypotheses were empirically tested using sample data from 37 countries of the Organization for Economic Co-operation and Development (OECD). The analysis period ranged from 2000 to 2019, which corresponds to an unbalanced group of 591 observations. Results: Eight different models were developed to analyse the proposed hypotheses. It was confirmed that reverse logistics has a positive effect on competitiveness, economic performance, environmental performance and society. Conclusions: Therefore, companies should pay attention to reverse logistics, as it will promote their development and benefit during their activities. The aspects highlighted in the article will help to understand the development and scientific substantiation of logistics management measures. The conclusions of this document can serve as a guide for leadership and management.

The aim of the paper is to evaluate the economic efficiency of the proposed modernization of the production process of crushed stone in the quarry and to decide whether to accept it or reject it. The project is assessed in a complex way. Profitability is evaluated using Net Present Value (NPV) and Profitability Index (PI), liquidity by means of Discounted Payback Period (DPP). The risk associated with the respective investment is assessed using a probabilistic method - Monte Carlo simulation.

The analysis of interorganizational relationships continues to attract academic research because of the influence that management of supply chain relationships has in business competitiveness. However, there are almost no studies about this decision in the mineral products industry. The purpose of this study is to investigate customer-supplier relationships in the non-metallic mineral products mining and manufacturing industry in order to determine what relational forms enable achieving better business competitiveness and higher quality relationships. To carry out this research, we propose a cohesive model comprising variables to characterize the transactions, the forms of governance and both economic and relational results. The paper is based on a transactional framework; thus, the adoption of one or another form of governance is addressed through the length of the relationship, the transmission of information and the dependencies between the agents. As for the outcome, the quality of the relationship is highlighted because of its importance in business competitiveness. The relational quality is understood as the stability of the relationship or the importance given by the buyer to maintaining the relationship or relational commitment. The hypotheses generated are contrasted by a structural equation model in a sample of 293 Spanish companies. The results confirm the importance of past relationships and integrated forms to get better results. In this sense, managers should encourage trust and dependencies because they positively affect performance. Trust and dependencies determine the choice of a vertical form of governance, and these factors, along with information, intervene in the quality of business relationships. Thus, it is possible to say that forms of governance do have effects on the interrelations between the characteristics of the transactions and the business performance.

Analiza powiązań międzyorganizacyjnych jest atrakcyjna dla badań naukowych ze względu na wpływ, jaki ma zarządzanie relacjami w łańcuchu dostaw na konkurencyjność przedsiębiorstw. Niemniej jednak, w decyzjach dotyczących przemysłu mineralnego nie ma prawie żadnych badań na ten temat. W artykule dokonano badań relacji między klientami a dostawcami w przemyśle górniczym i przetwórczym niemetalicznych surowców mineralnych w celu określenia, jakie formy relacyjne umożliwiają osiągnięcie lepszej konkurencyjności przedsiębiorstw i wyższe relacje jakościowe. W celu przeprowadzenia tych badań autorzy proponują spójny model, zawierający zmienne charakteryzujące transakcje, formy zarządzania oraz wyniki ekonomiczne i relacyjne. Artykuł oparty jest na ramach transakcyjnych; tym samym przyjęcie jednej lub innej formy zarządzania jest realizowane poprzez długość relacji, przekazywanie informacji i zależności między agentami. Jeśli chodzi o wynik to jakość relacji jest zaznaczona ze względu na jego znaczenie w konkurencyjności przedsiębiorstw. Jakość relacyjna jest rozumiana jako stabilność relacji lub znaczenie przekazane przez nabywcę do utrzymania relacji lub relacyjnego zaangażowania. Wygenerowane hipotezy są przeciwstawiane modelowi równości strukturalnych na próbie 293 hiszpańskich firm. Wyniki potwierdzają znaczenie wcześniejszych relacji i zintegrowanych form w celu uzyskania lepszych wyników. W tym znaczeniu, menedżerowie powinni zachęcać do zaufania i zależności, ponieważ wpływa to pozytywnie na wydajność. Zaufanie i zależności decydują o wyborze pionowej formy zarządzania, a te czynniki wraz z informacjami wpływają na jakość relacji biznesowych. Można zatem powiedzieć, że formy zarządzania mają wpływ na wzajemne powiązania między charakterystykami transakcji a wynikami działalności.

The article deals with impacts of innovative activities on productivity of businesses. The survey included 255 businesses participating in subvention programs focusing on support of innovative activities in companies. The study used the “two-sample t-test for means„ and “ANOVA“ methods. The values of productivity indicators were higher in the year after the subvention was received. However, the increase was not statistically significant. At the same time, no difference was confirmed in the achieved values of productivity indicators depending on the amount of the subvention in any of the monitored years.

Artykuł dotyczy wpływu działań innowacyjnych na produktywność przedsiębiorstw. Badaniem objęto 255 firm uczestniczących w programach dotacji skupiających się na wsparciu działań innowacyjnych w przedsiębiorstwach. W badaniu wykorzystano "dwu próbkowy test-t dla środków" i metody "ANOVA". Wartości wskaźników wydajności były wyższe w porównaniu do roku, w którym dotacja została otrzymana, jednakże wzrost ten nie był statystycznie znaczący. W tym samym czasie nie potwierdzono różnic w otrzymanych wartościach wskaźników wydajności w zależności od ilości subwencji w każdym z monitorowanych lat.

This paper presents the results of a thermodynamic and economic analysis concerning the use of gas from gasification of biomass in a cogeneration system with an internal combustion piston engine, working for the needs of a district heating network, with power of 1.5 MW in biomass supplied. The data on the gas generation and purification process were taken from real experiments conducted on a research installation with a fixed bed gasifier at the Institute for Chemical Processing of Coal in Zabrze. Electricity and heat generation efficiency and electric and thermal power of the system were primarily used as indicators of the thermodynamic evaluation. The economic analysis was carried out using discount methods, taking into account the existence of support mechanisms in the form of the colorful certificates. A sensitivity analysis of evaluation indices to the change of selected characteristics was performed.

High-tech manufacturing such as machining at high speeds, laser, electrical discharge machining are highly energy intensive. Automation of assistant processes such as transport, storage, quality control also causes increasing of energy consumption. In this context, important is estimating and minimize the volume used energy. The main contribution of paper is the evaluation method of energy production processes in automated production systems, based on the equation energy formulation. Simple calculation energy consumption example was also presented for elementary transport operations in a high storage depot. Implantation this method enables rating power consumption of manufacturing process on design stage where used are technical subsystems such as: machines, conveyors, manipulators etc. Designing processes with power rating consumption enable saving energy in manufacturing processes that is important for their economic efficiency.
