Optimization of logistics processes and activities in the function of supply-chain sustainability is a great challenge for logistics companies. It is necessary to rationalize processes in accordance with the strict requirements of the market, while respecting aspects of sustainability, which is not an easy task. Multicriteria decision making can be a tool that contributes to the optimization of logistics processes in terms of making the right decisions and evaluating different strategies in different logistics subsystems. In this paper, we considered the warehousing system as one of the most important logistics subsystems in a company. Conditions and the possibility of implementing barcode technology in order to optimize warehousing processes were evaluated. We formed a strengths, weaknesses, opportunities, and threats (SWOT) matrix consisting of a total of 27 elements. In order to determine the weights of all factors at the first level of decision making and its indicators at the second level of the decision making hierarchy, an original model was developed. This model involved the creation of a novel grey full-consistency method (FUCOM-G) and integration with a SWOT analysis. Since it was a matter of group decision making, we developed a novel grey Hamy aggregator that, by adequately treating uncertainties and ambiguities, contributed to making more precise decisions. The original grey FUCOM-SWOT model based on the grey Hamy aggregator represents a contribution to the entire field of decision making and optimization of logistics processes. Based on the applied model, the obtained results showed that Weaknesses, as part of the SWOT matrix, are currently the most dominant indicators, and that the implementation of barcode technology in a warehousing system is justified.

When defining criteria that have an influence on traffic accessibility in suburbs, it is necessary to take into account the specificity of a concrete urban unit. In existing scientific papers, the authors have dealt with the impact of the remoteness of settlements and their accessibility from the city center. The main aims of this paper are to define and quantify the criteria that have the greatest influence on traffic accessibility in suburban areas, that is, to develop a model of traffic accessibility. This model refers to traffic accessibility in suburban areas, where an urban public transport system is operational and represents a qualitative approach to research. Research has shown that factors such as a network of public transport (PT) lines, a network of accessible roads in a settlement, travel time, and timetables are of great importance in the description and generation of a new model. This model was tested in 23 suburban districts with regard to the needed walking time. The Fuzzy AHP (FAHP) method, one of the most popular methods for multi-criteria decision making, was used. Based on the results presented in this paper, it is expected that the application of this model will enable development and sustainability in suburban areas, as well as greater social equality and involvement of dwellers (especially the younger generation) in social activities, in view of achieving a better quality of life.

According to the European Committee (EC) on Transport, the future road transport strategy lies in creating a strong road transport sector which is based on a well-functioning internal market, fair competition and workers’ rights, decarbonization, and use of digital technologies. Urban and suburban passenger transportation systems, according to the principles of the EC, have a key role in achieving the goal of sustainable development and sustainable transport in cities. The fare, ticketing, and payment modes have a significant impact on public urban transport systems, primarily in terms of collecting transport service fees, and represent the basic source of financing of such systems, in addition to subsidies and grants from city budgets. This paper presents the selection methodology of the optimal fare system for urban public transport, applicable for all cities with an organized public city passenger transport (PCPT) system. Based on the established criteria with respect to setting tariff limits and fare systems, passenger demand, and the enterprise organizing the transport, the tariff system was selected. The presented method is that of multi- criteria optimization of the tariff system with numerical results on the example of the City of Novi Sad.

Bus rapid transit (BRT) is a system of public urban passenger transport (PUPT), based on the bus subsystem, designed to improve capacity and reliability compared to the classic bus system. Typically, a BRT system includes bus lanes and gives priority to buses at intersections where buses can interact with other traffic. Public transport is crucial to the future of a nation. Strengthens the economy, conserves energy and resources, reduces congestion, reduces global warming and improves air quality and health, critical emergency and disaster relief, increases real estate value and development, mobility in small urban and rural communities. As an instrument of transport policy, transport demand management measures generally do not require large material investments, which gives them additional attractiveness. The paper was conceived on the strategy of sustainable development of cities as a function of quality of life, and the basic characteristics of the BRT system and its role in urban mobility are presented in the work. Also, an insight into their potential is given based on past experiences of application in the world’s developed cities.

The primary driver of atmospheric pollution is humanity's demand for energy. Consequently, traffic and industry—particularly the energy sector—are considered the dominant sources of air pollution. Intensive motorized traffic significantly contributes to increased vehicular emissions, negatively impacting the atmosphere and all the environment. A range of negative effects of air pollution is observed, particularly in the urban environment, where one of the most considerable is the impact on human health. Air pollution affects all living organisms, leading to various health issues, including respiratory and cardiovascular diseases, allergic reactions, and even death. Due to urbanization, the prevalence of respiratory conditions, such as allergic asthma, chronic obstructive bronchitis, and chronic obstructive pulmonary disease, is increasing. Literature data shows that the emission of air pollutants (e.g. particulate matter, sulfur or nitrogen oxides) in developing countries, like Serbia, is higher than in industrialized ones. The study deals with the analysis of the health data and air pollutants emission data related to the energy sector and road traffic in Serbia, establishing the dynamic change trend in the period 2012-2022. Trend change dynamics were followed for the main air pollutants like black carbon, particulate matter, nitrogen dioxide, Sulphur dioxide, carbon monoxide, ammonia, and non-methane volatile organic compounds. The analysis showed the positive trend changes in the dominant air pollutants emission relevant for the observed industry sectors, during the 11 years. The emission rate of NO₂ from road transport in the period 2012 - 2022 shows a positive trend of change, and the share of NO₂ in total emission increased from 19.87% to 41.06%. Also, share of black carbon and various particulate matter in total national emission increased. Regarding the coal-power plant as a dominant energy source and a primary source of SO₂ emissions in Serbia, its emission rate fluctuated during the observed period. Nevertheless, its contribution to the total national emissions increased from 90.30% in 2012 to 95.56% in 2022. Regarding the results, future monitoring of the air pollutants emission level and implementing measures to improve the air quality in Serbia should be of high importance. Therefore, investment towards green transition and traffic planning, including the number and types of vehicles within urban areas, as a critical factor in mitigating air pollution levels, should be a priority. Furthermore, policies related to reducing air pollution emission from diverse sources should be harmonized with the European Union's regulatory framework to ensure alignment with empirical outcomes.

The number of taxi stands as well as their spatial distribution on the territory of the city have a great influence on the accessibility, i.e. the availability to users of taxi transport of passengers. The locations of taxi stands on the territory of each City are determined by the City Council of the City. In order to determine the optimal location and number of taxi stands in an area, the paper proposes a methodology for determining the location and number of taxi stands. An analysis of the location and functionality of taxi stands was performed on a case study in the territory of the City of Leskovac, and based on the conducted research, a methodology proposal was made for determining the optimal number and capacity of taxi stands with the function of spatial distribution of taxi stands in an area.
