Youth is one of the most active age groups traveling worldwide. Their travel style, goals, and criteria for choosing destinations differ significantly from those of other age groups. Domestic tourism is one of the most popular travel choices among young people. Local youth tourism invigorates the country’s tourism market, especially during the off-season. Therefore, positioning cities as attractive destinations for youth travel is a key objective for all major cities in Lithuania.

The aim of the study: to determine how Lithuanian youth perceive the attractiveness of Vilnius, Kaunas, and Klaipėda in the local tourism market.

When evaluating the components of tourist attractiveness for youth in Vilnius, Kaunas, and Klaipėda, respondents clearly differentiated the strengths of the analyzed cities. For Vilnius, the best-rated aspects were the overall atmosphere of the city, the general aesthetic appeal, the attractiveness of tourist sites, and the suitability of green spaces for visitors. In Kaunas, the highest ratings were given to cleanliness and order, the city's aesthetic appeal, and conditions for sports and active leisure. In Klaipėda, the top-rated factors were the city's safety, the appeal of the local community, and the transportation system within the city. On a ten-point scale, respondents rated Vilnius' attractiveness at an average of 8.45 points, Kaunas at 8.12 points, and Klaipėda at 6.74 points. The majority of respondents noted that youth from other cities would visit Vilnius, Kaunas, or Klaipėda more often if travel-related service prices were lower, if there were more events, more entertainment options, and more leisure venues.

The article presents options for the layout of a hotel building on a plot of land, modelling the efficiency of solar modules on the roof. At the initial stage of the project, when there are no restrictions from territorial planning documents, it is possible to select the optimal roof structure as well as the building orientation in relation to the cardinal points to maximize the exploitation of the power of solar modules installed on the roof. The modelling is performed using the PVsyst universal software for the design, analysis and optimization of solar power plants. After analysing the building models in four cardinal directions, the chosen position of the building model is the roof slope with solar modules turned to the southwest (according to the results of the two most efficient directions) – the rotation angle is 39° clockwise from the south. Solar modules oriented in the southwest direction generate 19,166 kWh/year, and after considering the tree shadows – 19,029 kWh/year (a difference of about 0.7%). Compared to the most efficient southern direction, the difference is 3%.

This article presents a methodology for evaluating the efficiency of a conveyor-based production line in the textile industry using an automated data collection system. The primary goal of the study is to assess production performance through real-time data acquisition and analysis. The developed approach enables efficiency measurement through two alternative methods: analyzing individual worker productivity and evaluating the overall production line output.

The research utilizes production data collected from a textile manufacturing company, incorporating both the company's ETON transportation systems and a previously proposed data collection device. Based on these data, mathematical models were developed to calculate efficiency metrics. The study evaluates 12 production periods, demonstrating that worker productivity does not always correlate with final production output. The results indicate that discrepancies between the two calculation methods are within 6 percentage points in 8 out of 12 cases. Larger deviations may signal operational inefficiencies such as bottlenecks, idle time, workflow disruptions, rework, or data entry errors.

The findings confirm that both efficiency evaluation methods are valid and can be applied to monitor production line performance. The insights gained from this study can contribute to optimizing manufacturing processes and improving overall operational efficiency. The proposed methodology provides a valuable tool for identifying production constraints and enhancing workflow organization in automated manufacturing environments.
