“…As a result, 131 people responded. According to figure 2 below, 47.3% were between the ages of [18][19][20][21][22][23][24][25]22.1% between the ages of 43-51, 14.5% between the ages of 34-42, and 10.7% between the ages of 26-33. As can be seen from the survey responses the majority of respondents fall between ages 18-25, which also shows that the majority of the public opinion which has been gathered by the survey will be that of a younger generation in Ulcinj.…”

All businesses are facing difficult economic and financial situations, many countries are facing bankruptcy situations of many activities, many economies are failing because they are unprepared for what awaits them. The COVID-19 situation brought the whole world to its knees. SMEs are most affected, as in the game of competition and market they fight for survival. These are the hypotheses that we will analyze in this scientific paper. We want to focus on a worrying issue for small Albanian businesses, and help these entrepreneurs find new ways and solutions to save them from bankruptcy. In this paper, the basic methods of conducting research are the combination of quantitative method and qualitative method. Qualitative research generally includes data in the form of words, descriptions, while quantitative research uses numbers and measures things. The decision to choose between quantitative research, qualitative research, or both depends on a number of factors, but the most important are: the field of research, the problem of research, and the perspective of the researcher. In the case of this paper, this combination has been realized as the analysis of the literature and the evaluation of the measures by the Albanian government towards university education requires the qualitative method. On the other hand, quantitative methods are needed to measure the effectiveness of these measures.In the analysis of our work we will focus on the concrete situation, as from the research we have seen that many small businesses (about 67% have gone bankrupt) Let us not forget that SMEs are the backbone of a country's national economy, and Albania is in great need of their economic and social impact. Therefore, we as professors of these disciplines request that through this research to bring in the focus of analysis the emergency situation in our country with the desire to serve entrepreneurs in new ideas of reviving their businesses.

Economic diplomacy is an important prerequisite for achieving the economic goals of any country. The issue is worth analysing from several aspects. Since there is a lack of literature in the field, this paper may be one of the first steps in this direction. It focuses on a clear exposition and explanation of multi-objective programming methodology and its connection with economic diplomacy at the micro-level. This connection is achieved by constructing a model that optimises funds allocation for economic diplomacy costs. The model uses multi-objective programming methodology and takes into account the relevant economic diplomacy funding determinants. It defines measurements of criteria, budget limitation, efficiency maximization, and location. The application of the model is illustrated by a numerical example.

This paper presents a new approach for solving decentralized bi-level multi-objective linear fractional programming problems. The main goal was to find a simple algorithm with high confidence of decision-makers in the results. First, all the linear fractional programming models on the given set of constraints were solved separately. Next, all the linear fractional objective functions were linearized, membership functions of objective functions and decision variables controlled by decision-makers at the highest level calculated, and a fuzzy multi-objective linear programming model formed and solved as linear goal programming problem by using simplex algorithm. The efficiency of the proposed algorithm was investigated using an economic example, and the obtained results compared with those obtained using an existing method.
