Research Question: This paper starts with the research question regarding the relationship between workplace conflicts and job satisfaction in the public sector in Serbia. Motivation: The main motivation for this research study was: to examine a compromising conflict resolution in the public sector in Serbia; to examine the frequency, causes, conflict resolution strategies and methods for their reduction and for improving work climate in the public sector in Serbia; to examine the job satisfaction in the public sector in Serbia; and to examine the relationship between workplace conflicts and job satisfaction in the public sector in Serbia. Idea: This research started with the intention to study job satisfaction or dissatisfaction and workplace conflicts in the public sector in Serbia in order to reach a more efficient and effective human resource management. Data: The research study was conducted from the beginning of March 2019 until the end of April 2019. The total sample size amounted to 300 respondents employed in the public sector in Serbia. Tools: Two scales have been used to gather data and conduct the research: the compromising conflict resolution scale and the job satisfaction survey scale. Findings: More than half of the respondents employed in the public sector in Serbia believe that conflicts in their workplace are not frequent, while less than half of them finds them frequent. This finding shows that opinions are divided regarding conflicts. As the main reason for conflicts, the respondents reported personal conflicts, organizational conflicts and communication conflicts. The best strategies to handle conflicts, according to the employees in the public sector in Serbia, are cooperation, competition and avoiding. At the same time, compromise occupies the bottom place according to its frequency occurrence. As regards the methods to lower the levels of conflict frequency and to improve the organizational climate, the employees in the public sector in Serbia emphasized better planning and division of work and more resources that a company has at its disposal. Regarding job satisfaction, these findings put employees in the category of ambivalent emotions. Contribution: The primary contribution of this paper is in its effort to lead to better human resource management in the public sector in Serbia due to the research study results.

Research Question: The paper will investigate the service quality of the higher education provided by the higher schools of vocational studies using SERVQUAL methodology. Motivation: The paper will show the characteristics of higher education of vocational studies, and it will point out the significance of creating and maintaining a quality management system in higher education institutions. The new reform of higher education in Serbia and establishment of academies of vocational studies are the main reasons why the question of service quality becomes one of the most important issues for higher education institutions and basis for competitive advantage, better image and reputation. Also, a growing competition on the higher education market and a smaller number of prospective students are also problems which higher vocational schools are faced with. Idea: The goal of this research is to find the differences between expected and perceived service quality. Furthermore, the paper will show if there are differences between perceived service quality among the students of different study years, as well as differences between the students with State scholarship and the self-funded students. Data: The research included 244 students of the first, second, and third years of bachelor studies from higher schools of vocational studies in Novi Sad, significant and the second-largest educational centre in the Republic of Serbia. Tools: Statistical methods used in this paper are frequency analysis, descriptive statistics, while the hypotheses are tested using the paired sample t-test, the independent t-test, and the one-factor variance analysis – ANOVA. Findings: The results of the research show that service quality of higher vocational education does not meet students’ expectations (sig.<0,001) and that the gap is negative for all dimensions of service quality (Tangibles (-.32), Reliability (-.52), Responsiveness (-.49), Assurance (-.33), and Empathy(-.26)). It is also shown by this research that there are no differences in higher education service quality based on the status of students (sig.>0.05) and the year of studying (sig.>0.05). Contribution: The results can be used as basis for introducing further measures to improve the quality of service provided by higher vocational institutions. [ABSTRACT FROM AUTHOR]

Research Question: This paper investigates into which competencies and competency areas are essential for graduates to be employable in Serbia. Motivation: The research was conducted with the aim to recommend to the Faculty of Organizational Sciences to adjust their curriculum, so that graduates could acquire competencies necessary for employment at junior positions. Combining qualitative and quantitative approaches, the paper includes required competencies according to popular reports, analysis of vacancies for junior positions in the field of Management and IT, focus groups and surveys conducted in companies in Serbia. Idea: The main idea of the research was to empirically evaluate the need and importance of general competencies for performing a job at junior positions. Participants in the research were experts from human resource management departments and domain experts from different fields who participate in the selection process. Data: During the research, 52 competencies from world reports, 60 competencies from open job vacancies, and 69 competencies during the focus group were analyzed. The questionnaire was created based on 29 competencies that were results from the qualitative research and filled out by 118 representatives from companies from different business domains. Tools: Content analysis of reports and vacancy ads, focus group report and statistical analysis of survey data (t test, Principal component analysis) were used to draw conclusions about required competencies for junior positions in the Serbian market and to categorize them. Findings: Competencies that are expected from future employees are to be socially skilled leaders capable of solving problems and intrinsically motivated to create and to be productive. Above all, they should be able to learn continuously. Specifically, when comparing managerial junior positions to junior IT professionals, it seems more important to be competitive, have strong presentation skills and to be conscientious. Contribution: Competencies important for graduates’ employability in Serbia are identified and grouped in different competency areas based on what universities’ curricula could be adapted.

The subject of the paper is to explain the impact of three braking negative transition factors causing the long-term stagnation of socio-economic development in the three selected countries of South East Europe (SEE) - Bosnia & Herzegovina, Montenegro, and Serbia. It is about institutional inefficiency (which is generated in the synergistic action of alternative institutions and neoliberalism), the post-socialist totalitarian legacy related to the nomenclatures of power, and the underdevelopment of socio-cultural capital. The aim of this paper is to prove their dominant influence on the reproduction of the socioeconomic development deficit (in fact: stagnation) in the observed countries through a hypothetically constructed survey model. The starting point is the basic hypothesis that the overall phenomenology of developmental stagnation is caused by wrong, slow, and inefficient institutional changes (political and macroeconomic), which have caused the dominance of alternative institutions. It also starts with the auxiliary hypothesis that privileged institutional monism (expressed in pronounced non-market appropriation) was the basic motive for the action of these braking factors, although methodologically and essentially it was in paradoxical contradiction with the proclaimed promises of “reformers”. In addition to the usual methods of social sciences, the paper used the results collected through an electronic survey of 900 respondents. In conclusion, the set hypotheses were verified, confirming the imperative need for democratization of society and the application of institutional pluralism on the model of developed countries, which implies the elimination of the considered braking factors.

Data on dust resuspension from solid waste landfills are unavailable in transition countries. Due the complex dust composition, its resuspension could cause serious health effect on surrounding inhabitants. In this paper, influence of resuspended dust from solid waste landfill in medium side city in Serbia on surrounding were modeled. Emission factor for dust resuspension were calculated according to the resent research and dispersion in air were simulated using ADMS Urban modeling software. According to the obtained results, modeled concentration in selected receptors were below limit values for dust defined by EU Directives. Even though simulation could be starting point for indication of pollution levels, systematic measurement around landfill is imperative in Serbia. [ABSTRACT FROM AUTHOR]

This paper presents a study of online teaching in higher education during the 2021/2022 school year, during the Covid 19 pandemic. The theoretical foundation of this research is Community of Inquiry (CoI) framework, according to which online teaching is realized through social presence (students’ interaction), teaching presence (student-teacher interaction) and cognitive presence (student-content interaction). This quantitative research was conducted in six countries: Serbia, Croatia, Bosnia and Herzegovina, Slovenia, Romania and Russia, and the answers were received from 808 students. At all participating faculties, online teaching was applied during the observed period, and in almost 80% of cases it was realized in full or to a greater extent than in in-person classes. The aim was to determine CoI presences and to identify possible differences among countries. The obtained data was processed with quantitative descriptive analysis and Kruskal–Wallis H test. The highest values of CoI presence were noted in Russia and Romania, then Slovenia and Croatia, and the lowest in Bosnia and Herzegovina and Serbia. In the whole sample, teaching presence has been most represented, followed by social presence, while the cognitive presence has been scored the least. Entire CoI presence was assessed as partially represented, as well as its three elements, the lowest of which is cognitive presence. In order to improve the online teaching process, in this paper technological and pedagogical training of teachers for online teaching, support for students for the use of digital tools for online learning and the provision of IT experts as necessary technical support are recommended.

Research background: Economic relations between countries members of the EU and EU candidates are very strong. Germany and France have the leading economies of the EU, are in the top ten economies worldwide, and drivers of EU development. Serbia has strong economic relations with Germany and France, especially with Germany. Therefore, it is necessary to examine whether Germany and France impact the development of Serbia. Purpose: The purpose of the study is to determine if there is a positive influence of a developed country on a developing country. The aim of the paper is to determine whether there is a long- and short-term positive relationship between Germany and France (EU members) and the Serbian economy (EU candidate). Research methodology: A Vector Error Correction Model is used to analyze quarterly data from 2002Q2 to 2018Q2. Results: The results showed a statistically significant long-term relationship between Germany and France and Serbia's real GDPs, so EU members have a long-term positive impact on the economy of EU candidates. In the case of the French, there is a short-run positive impact on the Serbian economy. For Germany, it is not the case. Novelty: This paper fills the literature gap about the influence of a developed country on a developing country. Recommendations for policymakers in EU candidates could be that if they want to motivate people to accept the process of access to the EU, they must provide them with more information about long-run economic benefits from the association to the EU.

The process of recognition of Kosovo has continuously declined since the Declaration of Independence until 2021, the period covered in this paper. This process is characterized by external structural obstacles, as well as internal non-structural ones. Applying the content analysis method and semi-structured interviews, the paper emphasized that the main structural obstacle was the inability to accept the Ahtisaari Plan from the UN as a compromise choice. On the other hand, the non-recognition of the state of Kosovo by Serbia (supported by Russia) resulted in the division of the states into two large groups: "pro" and "contra" recognition. Meanwhile, due to these extreme divisions, a third group of states sees the recognition of Kosovo as an opportunity to solve the previous obstacles. Thus, Serbia has established clear schemes to hinder the development of the process, first by sending the case of Kosovo to the ICJ and later by presenting the Kosovo-Serbia negotiation as status negotiations. Meanwhile, the internal political instability in Kosovo and the wrong political approach towards potentially recognizing states are evident as nonstructural obstacles in achieving new recognition.

In the past several years Serbia and surrounding countries became attractive environment for crypto currency hubs. Enterprises dealing with digital assets, which are present, dispose already over a 1 billion USD. Firstly, Serbian legislator adopted several regulations on this issue for the purpose of preventing money laundering, organised crime and terrorism. However, very soon it became necessary to create a legal framework for business, finance and attracting foreign investments. Serbia was among the early birds who adopted relatively complete regulation on digital assets in 2021. The purpose of this paper is to bring this very actual topic to the attention of the academic and broader public. The authors will analyse the legal framework in force and the use of digital assets in practice. New legislation represents one big step towards the modern business. Never the less there are some more actions to be done to include digital assets completely into the legal life in Serbia. [ABSTRACT FROM AUTHOR]

The main task of this research is to help to understand factors which are connected to the rise of prices of agricultural products, and to suggest adequate solutions for stopping inflation with the aim to obtain the supply of necessary foods in periods of crisis. In paper are recommended new strategies which will contribute to the proper treatment of agricultural production in the future and sustainable development. [ABSTRACT FROM AUTHOR]

Attempts to solve economic crisis by a massive injection of money into the financial system have caused inflation in most highly developed countries. World economy is burdened by a high inflation, excessed demand, over indebtedness, in one word unready for the challenges that followed on the geopolitical level, and have spilled over into the economy. This situation has also affected agriculture, while the rise in food prices was particularly sensitive because it has affected the population life standard. All existing weaknesses of the economic and agrarian policy of Serbia and absence of a serious long-term strategy in this seriously in crisis sector's development have surfaced. This paper analyses a situation in the Serbian agricultural sector, which has been pressured at the same time by bad agrarian policy, numerous internal weaknesses and big geopolitical risks.

Citizens of Serbia participated in the research (n = 399). The methodology is based on a questionnaire that obtained the data that were processed via t-test statistical methods for independent samples, one-factor analysis of variance, the χ² test, and Pearson's correlation coefficient. Based on the conducted research, it can be stated that about 70% of respondents are willing to pay a higher price for these products. [ABSTRACT FROM AUTHOR]

Research question: The study researches the key success factors of a shopping mall project (SM) from the perspective of creditors in Serbia. Motivation: In Serbia, the retail landscape has seen a continuous increase in the number of SMs over the recent years. To support further development, project finance (PF) plays a significant role as an adequate financing structure for such projects. Idea: Existing knowledge highlights the importance of different factors for the sustainability of SM operation in the long run, describes their impact on project success, or offers potential solutions to a specific business problem. On the other hand, a question may be raised regarding the creditor’s ability to assess the quality of different investor decisions when deciding to finance a concrete project. Data: Research is based on the review of papers published in relevant international journals, while the presented case study is a real-life example from banks’ business practice. Relative significance of different factors from the creditors’ perspective was established and confirmed by means of a survey among bank professionals. Tools: Research findings are derived from a case study and simple empirical research conducted among bank professionals in Serbia. Findings: Results show that the most important elements of the project strategy which creditors consider relevant for project success in the long run are location and tenant mix. Contribution: Research results contribute to a better understanding between investors and creditors and may shorten the time needed for the credit approval process. [ABSTRACT FROM AUTHOR]

The problem of managing working capital, i.e. net working capital in trade, is very specific, challenging, current, significant and complex. In order to achieve the target financial performance, it is necessary to manage working capital as efficiently as possible. Based on that, this paper analyses the dynamics of size and the impact of net working capital on the profitability of trade in Serbia. In the period 2013 - 2021, in the trade of Serbia, the maximum amount of net working capital was achieved in 2021, the maximum percentage of net working capital from assets was achieved in 2021, the maximum percentage of net working capital from sales was achieved in 2021, and the maximum profitability was achieved in 2021. In the specific case, there is a strong correlation between profitability and net working capital of trade in Serbia. The coefficient of determination is high (Adjusted R Square .941; Sig. F Change .000). The influence of net working capital on the profitability of trade in Serbia is very significant (Sig. .000). This means, in other words, that more efficient management of net working capital can have a significant impact on the profitability of trade in Serbia. Observed dynamically, the amount of net working capital of trade in Serbia has increased recently. This had a positive impact on its liquidity, solvency, efficiency and profitability. Recently, the productivity of trade in Serbia has also increased. The factors that influenced it were: favourable economic climate, foreign retail chains, application of new business models, new concepts of management of costs, income, profit, customers, product categories, application of the concept of sustainable development and digitization of the entire business.

Purpose: According to ISO 9000:2015 "the primary focus of quality management is to meet customer requirements and to strive to exceed customer expectations", where "a customer can be internal or external to the organization". Internal customers refer to a company's employees, while external customers are the buyers of a company's products and services. Previous research has scrutinised the impact of ISO 9001 on company performance, without clear focus on the performance related to internal and external customers. Methodology/Approach: The purpose of this paper is to measure the impact of ISO 9001 on the performance to internal and external customers using a survey that has been responded by 141 companies in the Republic of Serbia. Findings: The results show that quality management system (QMS) certification to ISO 9001 enhances employee- and customer-related company performance, while certification incentives are found to influence this relationship. Research Limitation/Implication: The data are gathered in only one specific country, although there are no reasons to think that the results could depend of the specific analysed region. Originality/Value of paper: The main value of the article is to be one of the first ones to analyse, in any way, the impact of QMS on internal and external customers.

Volatile energy prices in the past period, force countries and their market participants to find alternative and cheaper sources of electricity production, while respecting defined environmental principles. Serbia is one of the rare European countries that uses its reserves of dissolved gas in the heat and electricity production. Combined heat and power plants, although in an almost negligible amount, contribute to the diversification of Serbia's production mix. With the presence of organized markets and local power exchanges, sale of electricity from combined heat and power plants is guaranteed for all producers who do not meet the conditions for acquiring the right to feed-in tariffs. The aim of this paper is to analyze the most profitable sale on the power exchanges of the domestic market and the region, specifically the markets of Serbia, Croatia, Hungary, Romania, and Bulgaria. The calculation methodology itself implies the use of average monthly price value for the observed markets, in the period of the past three years and nine months. In addition to the aforementioned, the costs of cross-border capacities were considered. In order to have a clearer overview of the results and the possibility of applying the methodology, the amount for calculation is 1 MWh. Costs and revenues related to negative and positive balance energy deviations are excluded from the analysis. Results showed that sale of electricity is most profitable on Serbian power exchange.

The circular economy is a new economic model which provides the necessary goods and services for maintaining and improving living standards without increasing the consumption of raw materials and waste. The traditional model of the linear economy is viewed as an unsustainable long-term solution because it does not take waste treatment into account, and thus the impact on the environment. The European Union has recognized this problem and obliged its members to apply the circular economy model as a strategy for a climate-neutral, resource-efficient, and competitive economy. By adopting the European Green Deal at the Western Balkans Summit, the Republic of Serbia has committed itself to abide by the new growth strategy, which includes the application of the circular economy in all industrial sectors. The construction industry is one of the most environmentally harmful industries in the world, with a direct impact on the use of raw materials, life cycle of buildings, and the overall environment. The paper explores the circular economy concept, its principles, and possibilities for implementation, both at the national level of the Republic of Serbia and the level of the European Union. The role of the circular economy in the construction industry has been examined through the analysis of legislation currently in force with regard to the treatment of construction materials and waste. This paper aims to highlight the importance of employing the circular economy in the Republic of Serbia, as well as to define guidelines for its further implementation, especially in the reconstruction and adaptation of buildings.

Nutrient pollution represents an ongoing problem and a great challenge to water resources management around the world. Therefore, the aim of this paper is to contribute to the efforts of the water resources management in considering a problem of the nutrient pollution of water from a multicriteria decision-making point of view. The combined PROMETHEE and GAIA analysis in this paper included indicators of nutrients in the water (total nitrogen, nitrite, nitrate, ammonium ion, total phosphorus, and orthophosphates) to rank and evaluate significant sites along the Danube River flow through Serbia. Furthermore, the ecological quality status of the water was determined which places the Danube River into the category of "good" to "moderate" water quality. The results represent a detailed evaluation of the sites with increased nutrient content, associated with the most dominant parameters of nutrient indicators affecting water pollution at each site. The main sources of nonpoint pollution are of anthropogenic origin reflected in agricultural applications of pesticides and fertilizers, together with natural contamination of ground and water sources, while pollution from point sources arises from industrial waste waters as well as from domestic activities. Minimizing the application of fertilizers and pesticides is a way to control pollution from agricultural activities while, at the same time, a proper wastewater treatment is needed to reduce point sources, although financial aspects and lack of funds are limiting factors of this control in Serbia. Therefore, the findings in this paper could serve environmental scientists and water resources managers as a starting point in identifying key sources of nutrient pollution in water, as well as industry experts and national authorities in expanding strategies and taking long-term measures to reduce the input of nutrients into the valuable Danube River.

The guarded hot plate (GHP) method is a widely used technique to measure thermal conductivity of thermal insulation specimens in steady-state conditions. In this paper, an advance of GHP has been developed in the Laboratory for Thermal Technique and Fire Protection in Institute IMS. The innovative GHP has been applied for measuring thermal conductivity using additional heat flux meters. The design of this GHP is similar to the design of the plate for GHP apparatus, however, it has different design: smaller width of thermal barrier, which is filled with insulation glue. Heaters inside hot and guard plates are built from wire for thermocouples, which is a unique type of heater. Geometry of heater has been optimized inside plates to achieve uniform temperature distribution along the specimen surface. Temperature uniformity of GHP and energy balance were experimentally determined. The verification and validation results of improved GHP have been shown. The test method was validated comparing test results of thermal conductivity with results of the round-robin test. Four national companies participated in the round-robin comparison on thermal conductivity measurement by GHP method. The measurement was performed on the same specimen of thermal insulation material (expanded polystyrene) according to SRPS EN 12667 at temperatures ranging between 10-40 °C. The measured thermal conductivity of all participants in the round-robin test was input data for statistical processing according to SRPS ISO 5725-2 and ISO 13528. To evaluate the performance of the participants, the "z " score has been used. Measurements were conducted successively for all participants. Since 2020, the Accreditation Body of Serbia also approved this test method. [ABSTRACT FROM AUTHOR]

The article offers information on the scientific publication "Glasnik Instituta za botaniku i botaničke bašte Univerziteta u Beogradu," which was considered as the oldest botanical journal in Serbia and has been renamed "Botanica Serbica." It states that the Botanical Institute of the Belgrade University has published the first issue of the journal in 1928 with botanist Nedeljko Košanin as the founder and editor. It mentions that the journal featured topics on endemic species and conservation of rare plants, and several papers on phytogeography, plant physiology, and mycology. It also says that the journal is a useful source of information for botanists who deal with flora and vegetation distributed in Southeastern Europe.

The main objective of this paper stems from the need to provide new insights into the competitiveness of the agricultural products distribution system in the Republic of Serbia, through determining the impact of customer contact as part of the agricultural distribution channel on the competitiveness of agricultural holdings. The survey was conducted on a sample of 126 farms from the territory of the Republic of Serbia through a closed-type survey (12 claims related to customer contact and 15 claims related to the competitiveness of the agricultural products distribution system; five-stage Likert scale), which was distributed electronically. The contribution of the paper is reflected in the results which showed that the level of customer contact (as part of the distribution channel) influences the level of competitiveness of the agricultural products distribution system (in the Republic of Serbia). The results also form the basis for further research in this field. [ABSTRACT FROM AUTHOR]

This paper investigates the use of neural networks (NNs) for the problem of assigning push boats to barge convoys in inland waterway transportation (IWT). Push boat–barge convoy assignmentsare part of the daily decision-making process done by dispatchers in IWT companiesforwhich a decision support tool does not exist. The aim of this paper is to develop a Neural Network Ensemble (NNE) model that will be able to assist in push boat–barge convoy assignments based on the push boat power.The primary objective of this paper is to derive an NNE model for calculation of push boat Shaft Powers (SHPs) by using less than 100% of the experimental data available. The NNE model is applied to a real-world case of more than one shipping company from the Republic of Serbia, which is encountered on the Danube River. The solution obtained from the NNE model is compared toreal-world full-scale speed/power measurements carried out on Serbian push boats, as well as with the results obtained from the previous NNE model. It is found that the model is highly accurate, with scope for further improvements. [ABSTRACT FROM AUTHOR]

This paper emphasises the role of people who have been employed at the Institute of Architecture and Urban & Spatial Planning of Serbia as well as a number of its external associates in the development of spatial planning in Serbia. It highlights the significance of the publishing role of the Institute, which goes hand in hand with its work on scientific research and professional projects, with a special focus on the journal Savremene urbanističke teme (Engl. Contemporary Urban Themes), one of its five serial publications. This journal is significant because it published analytical and study articles, translations, critical reviews, and reviews of important achievements in urban and spatial planning at a time when spatial planning in Serbia was still in its pioneering phase, which resulted in the launch of ambitious projects with a wider social impact. The important contribution of this paper is the bibliography of the journal Savremene urbanističke teme, as well as four accompanying registers that present all of the authors of its texts and all of the published titles.

Buildings are significant energy consumers and provide a notable potential to reduce primary energy consumption and increase energy efficiency. Cost-effectiveness of energy efficiency projects is of crucial importance for their implementation. Cost-optimality of different packages of energy retrofit measures is studied across the EU, but Serbia mostly lacks such information. This paper analyzes cost-optimal solutions for Serbian residential buildings connected to district heating systems, considering three different scenarios related to the economic input parameters. Additionally, it considers the potential for primary energy savings beyond cost-optimality and associated costs. The optimal solutions, that correspond to minimal global cost or minimal primary energy consumption, are determined as the results of the combinatorial optimization problems. These problems are solved using the genetic algorithm and local search. The results are compared against the ones obtained with the sensitivity analysis. The global cost can be reduced by 8-43% in the cases of cost-optimal solutions, simultaneously saving 30-76% of primary energy. The potential to save primary energy is higher - it exceeds 70% in all the analyzed cases, but also requires higher global cost, sometimes larger than in the absence of the retrofit. The paper also emphasizes high dependencies of the results on very uncertain economic inputs. [ABSTRACT FROM AUTHOR]

The paper starts with the initial hypothesis that traditional, i.e. local food served in local restaurants (chardas) is the basis for the development of rural areas. By setting certain sub-hypotheses, we highlight the primary purpose of the paper, and thus we show that traditional food has the "strength" to change and improve rural areas. We based the research on a changed questionnaire previously used for research in the Black Sea resorts of Romania. The questionnaire comprises of 9 attributes, and we asked respondents to rank certain attributes on a three-point scale. The research was conducted among visitors who came from eight countries, including Serbia, to get the most relevant data through statistical processing, which will serve to assess the current, but also to predict the future state and development of gastronomic tourism.

Various methods of multicriteria optimization have been developed and have recently been widely applied in trade. With this in mind, this paper investigates the performance of food retailers in Serbia based on the ELECTRE method. The goal and purpose of researching the efficiency problems of leading food retailers using the ELECTRE method is to see as realistically as possible their position on the food market in Serbia in order to improve in the future by more efficient control of critical factors and implementation of relevant measures. In addition to the challenges, topicality, significance and complexity, the reasons for researching the given problem in this paper are reflected in that. In addition, by applying the ELECTRE method, more realistic results are obtained in relation to the ratio analysis, especially in combination with other methods of multicriteria analysis (TOPSIS, AHP, ARAS and others). The results of the research show that Delhaize Serbia is the best company in terms of performance. This is the result of Delhaize Serbia's good position in the retail market in Serbia. It applies new business models (private label, sales of organic products, multi-channel sales - stores and electronic). It applies modern concepts of cost management, sales, assets, capital, customers, product categories and profit. In addition to all that, the digitalization of the entire business is at a high level. These and other factors have positively influenced its good positioning on the retail food market in Serbia. [ABSTRACT FROM AUTHOR]

This paper proposes an optimal solution for the design of a hybrid power system that will supply a remote fishpond in eastern Serbia. In terms of structure, this off-grid system should be a hydro-photovoltaic-diesel-converter-battery setup. The optimization objectives are to minimize total net present cost (NPC) and greenhouse gas (GHG) emissions and to maximize total annual electricity generation based on the modification of hydro-turbine performance. This study considers the following three cases of a hydro-turbine with fixed propeller blades: having fixed guide vanes, for the annual average flow rate-Case 1; having adjustable guide vanes, for smaller flow rates-Case 2 and having adjustable guide vanes, for higher flow rates-Case 3. The optimization is performed using HOMER Pro v. 3.16.2 software. The results show that the total NPC, levelized cost of energy (COE) and GHG emissions in Case 3 are 16.6%, 16.8% and 13.1% lower than in Case 1, and 8.1%, 8% and 11.7% lower than in Case 2, respectively. It is also found that the total annual electricity generation and power output from the entire system in Case 3 are 33.3% and 1.2% higher than in Case 1, and 11.9% higher and not different than in Case 2, respectively.
