The methods and tools for the performance measurement and evaluation of the green supply chain management are very important elements for the construction and function of this type of supply chain. The result is a presentation of the considerations underlying a very general model, which presents some selected tools, but no breakdown of individual industries. The considerations undertaken are important and have scientific added value as usually in practice, a very large number of tools are used to assess the supply chain, which are not always correlated or adapted to the specificity of the chain. It is worth pointing out which of the already used or completely new tools and methods will be most useful for assessing the green supply chain. The structure of the paper covers the theoretical and empirical. It includes an introduction, our goals and hypotheses, state of the art, methodology, empirical findings, and discussion. We present the definitional differences between green and sustainable supply chains and focus on the selection and identification of methods for the framework model for evaluating the green supply chain. In the next step, the theoretical and selected method and tools were compared to a survey of Poland. On the basis of the survey, we present the findings and discussions found in this area. The main methodology used includes a literature review, a survey analysis using a questionnaire and statistical tools. The survey was carried out in 2015 in sample organizations in Poland. The research results showed that organizations were aware of the environmental elements of measuring and assessing the supply chain from an environmental point of view, but their use depended on many factors: the area, size of the organization, or the industry. If certain boundary conditions are met and the organizations are aware of the essence of environmental aspects in the chain, then they are applying green measures to the supply chain. These findings provide a glimpse into the measurement system and show that organizations still have yet to understand the essence of green and sustainable performance measurement, the meaning of its application, and the benefits it brings. However, traditional measurement still plays a large role, so it is important to reflect on how to convince organizations to pay more attention to environmental aspects, while at the same time applying a green supply chain assessment model. These results are a framework in which to start building a green supply chain assessment model. The empirical research aimed to answer the question of whether theoretical and sustainable management tools have already played a role in perceiving and assessing the green supply chain.

This paper proposes a heuristic method based on ant colony optimization to determine the suboptimal allocation of dynamic multi-attribute dispatching rules to maximize job shop system performance (four measures were analyzed: mean flow time, max flow time, mean tardiness, and max tardiness). In order to assure high adequacy of the job shop system representation, modeling is carried out using discrete-event simulation. The proposed methodology constitutes a framework of integration of simulation and heuristic optimization. Simulation is used for evaluation of the local fitness function for ants. A case study is used in this paper to illustrate how performance of a job shop production system could be affected by dynamic multiattribute dispatching rule assignment.

The aim of the article is to present and analyze the implementation of intelligent lighting within the concept of smart energies and smart cities. Motivation and research hypothesis: Electricity consumption in the world is based largely on non-renewable energy. Until these full changes, it is necessary to look for opportunities to save and use it efficiently. Today’s cities are increasingly implementing the smart concept, of which smart energy is one area. One of the smart city elements implemented by cities is smart energy. Within this framework, a supported concept is the replacement of traditional lighting with LEDs (Light-Emitting Diodes), which contributes to energy and cost savings and reduces the pollution of the sky with artificial light, while increasing the efficiency of urban lighting. Positive effects of modern solutions include reduced lighting expenses and increased safety of residents. Methods and results of the research: The authors chose the case study method for their research. The authors present forecasts for the development, not only from the point of view of the number of lamps but also the cost efficiency pointing out the importance of this element in the context of building smart cities. These are specific benchmarks for cities that have not yet implemented this concept. Conclusions and interdisciplinary implications: solutions are desirable directions for the development of the smart city concept, bringing benefits and reducing external costs. Considerations show a quantitative development forecast and an indication of the possibility of achieving trade-offs and cost reductions. It translates into meeting the requirements of sustainable development providing tangible benefits. The analysis of the case studies is intended to show the effects that can be achieved and the wide range of applications (indicating that modern lamps are not just lighting, but a platform for urban services). The analyses presented are intended to serve as benchmarks showing the possibilities of reducing costs and increasing the quality of life of residents in modern cities. The indicated examples and analyses are of economic importance, they show managers, but also inhabitants, in which direction they should lead the smart city concept, which will allow saving costs, but also to increase the quality of life of inhabitants.

Creating alternative supply chains can help increase economic and social benefits for all beneficiaries of the supply chain. Alternative short supply chains for organic products are considered when seeking optimal scenarios to obtain the highest profit for producers, with maximizing profit being one of the main reasons for taking up business within this type of supply chain strategy. The aim of this study was to clarify the ideas of short food supply chains (SFSCs) and the organic production of food products and to indicate how economic benefits can be achieved in individual markets. The identified research gaps include the lack of a strong theoretical basis, as well as the lack of empirical studies concerning the multi-objective optimization of the economic effects of producers using computer simulation methods. However, the aim of this research was to identify the activities within such structures that can produce economic effects and influence the competences and soft relationships between the organizations participating in the chains. The adopted research methods included a critical analysis of the literature and the use of information technology tools and computer simulation. We found that computer simulation methods can lead to better decisions (to increase manufacturer benefits) regarding how to service selected markets within the SFSC. The most important limitations are the small territorial scope of the research and the consideration of only three of the most frequently purchased and manufactured products in Poland. This study was a pilot study, which will be developed further by the authors, from both a territorial and product point of view.

Celem artykułu jest zaprezentowanie modelu doboru metodyk zarządzania projektami do jednostkowego zlecenia produkcyjno-usługowego. Dobór odpowiedniej metodyki zarządzania projektami jest jedną z ważniejszych decyzji, jaką musi podjąć przedsiębiorstwo, aby skutecznie zaplanować i zrealizować swoje projekty. Decyzja o wyborze metodyki zarządzania projektami uzależniona jest od wielu kryteriów, takich jak: doświadczenie zespołu projektowego, wielkości projektu, zaangażowanie klientów itp. Tak duża liczba kryteriów do przeanalizowania powoduje konieczność zastosowania odpowiedniej metody. Jedną z tych metod może być metoda hierarchicznej analizy problemu decyzyjnego (AHP). Metoda AHP została zastosowana do wyboru metodyki zarządzania projektami dla jednostkowego zlecenia produkcyjno-usługowego. Z przeprowadzonych badań wynika, że najlepszym rozwiązaniem problemu doboru odpowiedniej metodyki zarządzania projektami jest w tym przypadku wykorzystanie standardu PMBOK.

Financial knowledge is the main element of financial literacy, which is important for the sustainable development of individuals and society. Sustainability is a complex concept that spans many fields, including financial knowledge for all ages. Financial knowledge requires significant scientific research showing its impact on individuals and the economy, including non-cash payments. Consumer payment knowledge and its association with consumer financial behavior have long been a matter of widespread interest by researchers, but no in-depth, empirically based scientific research has been completed for Poland. The objective of this study was to examine factors associated with cashless payment behavior with an emphasis on the role of consumer financial knowledge. A total of 1100 interviews were carried out with Polish nationals aged 15 and above. The collected data were analyzed with the use of statistical methods, including analysis of variances (ANOVA), in order to examine consumers’ financial knowledge by basic economic and non-economic factors. Additionally, a data-mining method known as Random Forests was implemented for finding the variable importance in correlations between consumer financial knowledge and preferred methods of payment. The results revealed the diversity of factors influencing consumer behavior. Among the consumers’ personal traits, financial knowledge was one of the most important determinants of their payment choices. The results have implications for the design of payment processes. The results can be used by central banks to determine the directions of financial inclusion, as well as for stakeholders in the payments market.
