Healthcare systems worldwide are facing problems in providing health care to patients in a pandemic caused by the SARS-CoV-2 virus (COVID-19). The pandemic causes an extreme disease to spread with fluctuating needs among patients, which significantly affect the capacity and overall performance of healthcare systems. In addition, its impact on the sustainability of the entire economic and social system is enormous and certain sustainable management strategies need to be selected. To meet the challenges of the COVID-19 pandemic and ensure sustainable performance, national healthcare systems must adapt to new circumstances. This paper proposes an original multi-criteria methodology for the sustainable selection of strategic guidelines for the reorganization of a healthcare system under the conditions of the COVID-19 pandemic. The selection of an appropriate strategic guideline is made on the basis of defined criteria and depending on infection capacity and pandemic spread risk. The criteria for the evaluation of strategic guidelines were defined on the basis of a survey in which the medical personnel engaged in the crisis response team during the COVID-19 pandemic in the Republic of Serbia participated. The Level-Based Weight Assessment (LBWA) model and Measuring Attractiveness by a Categorical-Based Evaluation Technique (MACBETH) method were used to determine the weight coefficient criteria, while a novel fuzzy Ranking of Alternatives through Functional Mapping of Criterion Subintervals into a Single Interval (RAFSI) model was used to evaluate the strategic guidelines. The proposed multi-criteria methodology was tested in a case study in the Republic of Serbia. The validity of the proposed methodology is shown through the simulation of changes in input parameters of Bonferroni aggregation functions and through a comparison with other multi-criteria methodologies.
Decision making is constantly present in agriculture. Choosing the wrong variety carries the risk that the investment in terms of sowing does not pay off at all. Therefore, it is necessary to choose the variety that gives the best results. In order to achieve this, it is necessary to apply multi-criteria decision-making of available varieties, which is, in this paper, done on the example of hybrid varieties of rapeseed that were created by selection at the Institute of Field and Vegetable Crops in Novi Sad. By applying fuzzy logic, a novel integrated Multi-Criteria Decision-Making (MCDM) model is developed and rapeseed varieties were evaluated. For determining four main and 20 subcriteria, fuzzy PIPRECIA (PIvot Pairwise RElative Criteria Importance Assessment) method has been applied based on fuzzy Bonferroni operator, while for ranking alternatives fuzzy MABAC (Multi-Attributive Border Approximation area Comparison) method has been used. The results obtained using the novel integrated fuzzy MCDM model showed that the variety A2 – Zorica has the best results, followed by A1 - NS Ras, while the worst results were seen by the variety A5 - Zlatna. These results were confirmed using other five fuzzy MCDM methods. Sensitivity analysis—changing criteria weights showed the worst results in the variety A6 - Jovana, which took last place in the application of 18 scenarios. The presented model and the results of this research will help farmers to solve this decision problem.
Brands have become an important factor in the survival of organizations in modern society. They are present in all spheres of life: economic, social, educational, cultural, sports, etc. Powerful brands are the result of thoughtful and imaginative planning. Brand positioning has a strategic importance for a company, because it represents the process of creating an impression in consumers' minds in a way that the consumer connects the brand with something specific and desirable, which distinguishes one brand from others. Brands have a financial value as they create an image of the values themselves in the minds and hearts of consumers. A brand can make consumers believe in its usefulness, exclusivity and superiority, and it also creates emotional attachment. There are numerous factors that influence the position of a brand in the consumer's mind. University students are considered consumers, too. The aim of this paper is to research students' satisfaction with faculties by using the parameters that are considered to be relevant. In this process, we will apply the factor analysis and, instead of focusing our attention on a large number of initially determined factors, thanks to the process of their reduction, we will create the conditions that will allow us to design a strategy for the optimization of the selected factors. Using this method, we will mark the factors that explain the researched phenomenon, i.e. the factors that can explain the largest part of its overall variability.
Универзитет Привредна академија у Новом Саду, Факултет за примењени менаџмент, економију и финансије, Београд Сажетак: Бренд представља вредну неопипљиву имовину и један од најважнијих ресурса, који нуди низ користи, и зато се бренд мора константно изграђивати и њиме се мора пажљиво управљати. Компаније маркетиншким активностима настоје да створе снажан и препознатљив бренд, који је заправо нешто што почива у умовима купаца. Стварање бренда подразумева низ активности на осмишљавању елемената бренда, јединственог заштитног знака, карактеристичних пропагандних порука и осталих активности у циљу позиционирања бренда на тржишту. Циљ процеса стварања тржишне вредности бренда јесте максимално могуће увећање његове вредности. Три најзначајнија модела у процесу планирања и изградње бренда јесу модел позиционирања бренда, модел одјекивања бренда и модел ланца вредности бренда. Кључне речи: бренд, стварање бренда, модели креирања бренда, тржишна вредност бренда
This paper proposes a new integrated model based on SWOT and extended PIvot Pairwise RElative Criteria Importance Assessment (PIPRECIA) that offers a systematic approach to strategic planning in tourism. The applicability of the proposed integrated model is demonstrated through a case study defining the main determinants of tourism development in Serbia. The result emphasizes the strategy Improving the organization, management, and enhancement of tourism development as the highest priority for implementation. The model facilitates decision-making in tourism, and its key advantages are its suitability for application in group decision-making and its simplicity.
