The article focuses on current issues in the field of application of Decision Support Systems (DSS) in the management of photovoltaic (PV) projects. In the era of renewable energy growth and the increasing need for environmentally sustainable solutions, PV projects are becoming increasingly important. In order to successfully execute such projects, informed decision-making and optimal resource utilization are required. One effective solution in this direction is the implementation of an integrated DSS, which supports the decision-making process. The article assesses the functions of DSS in PV projects, with a particular emphasis on its capabilities for data management and analysis, scenario analysis and simulation, as well as risk assessment and management. Using the case method, the importance of DSS in improving decision-making, optimizing resource allocation and increasing the efficiency of PV projects is argued.

  Preliminary Evaluation of the Effect of the European Green Deal on the Agricultural Sector in the EU

  The European Green Deal is a new strategy for the overall development of the EU, which horizontal nature leads to the creation of regulations and requirements simultaneously affecting several economic sectors and policies.

The European Green Deal is a new strategy for the overall development of the EU, which horizontal nature leads to the creation of regulations and requirements simultaneously affecting several economic sectors and policies. Assessing the effect of the Green Deal on the agricultural sector requires looking at the overall situation created since its adoption. The purpose of the article is to review the individual elements of the Green Deal and the regulations based on it, in order to identify the potential effects on the agricultural sector. The assessment should consider not only the direct impact on production, exports, competitiveness and farmers' incomes, but also on food prices and food availability. The contribution of agriculture to climate, natural resources and biodiversity should also be taken into account.

The study analyses the levels and the dynamics of uncertainty as a fundamental element of the macroeconomic environment during the COVID-19 crisis. The focus is on the modelling of uncertainty on the basis of the market approach for quantifying it. The process of modelling results in the calculation of indicators through which a comparative empirical evaluation is done. In terms of the economies included, the comparative analysis encompasses the EU and the United States. The analysis is conducted on two levels that go side by side and complement each other. The first one consists of comparing the periods for the concrete economy. The results show similar trends for the EU and for the United States. For the three periods, defined in the study, the sequence of the changes does not differ for the two economies. The second level includes a comparative analysis of the same periods between the economies. The results exhibit a considerable similarity in the levels of uncertainty. For the first two periods the differences are not even statistically significant. For the third period, however, there is a greater difference which is characterized by statistical significance.
