They must, however, balance innovation with strict GDPR requirements.This study compares a cloud-based large language model (OpenAI’s GPT-4 API) against an on-premises deployment of an open-source LLM (Llama 3–13B) for hotel customer-service chatbots. We evaluate both solutions in the context of Cogniforce Labs deploying chatbots for regional hotels, focusing on GDPR compliance, operational cost, response latency, and customer satisfaction. Using three common use cases (booking modification, late check-in, and local recommendations), we simulate chatbot interactions and measure performance. The results show that the on-premises LLM offers superior data privacy (all guest data remains in-house, aiding GDPR compliance) and lower latency (up to ~35% faster responses), along with a more predictable cost structure. The cloud GPT-4 solution, however, delivers slightly higher answer quality, yielding greater customer satisfaction scores, at the expense of transmitting personal data to a third-party and incurring usage-based fees. Our findings suggest a trade-off between compliance/cost and service quality. Hotels prioritizing privacy may favor on-premise LLMs, while those emphasizing customer experience might opt for cloud AI with proper safeguards. We discuss hybrid strategies and provide recommendations for hospitality businesses navigating this choice.}, keywords = {GDPR; Hospitality; chatbots; Cloud AI; Language Large models; On-Premises AI}, year = {2025}, pages = {16-21}, orcid-numbers = {Szabó, László/0000-0003-4153-8432} } @inproceedings{MTMT:36884604, title = {ICT APPLICATION FOR PREDICTIVE MAINTENANCE AND LOGISTICS EFFICIENCY IN INDUSTRIAL ENTERPRISES}, url = {https://m2.mtmt.hu/api/publication/36884604}, author = {Mihalj, Bakator and Szabó, László and Natasa, Dalic and Dragan, Cockalo and Sanja, Stanisavljev}, booktitle = {Proceedings of the XV International Conference on Industrial Engineering and Environmental Protection IIZS 2025}, unique-id = {36884604}, year = {2025}, pages = {216-223}, orcid-numbers = {Szabó, László/0000-0003-4153-8432} } @article{MTMT:34478440, title = {Examination of Logistics Simulation Demand Related to Enterprises: Focusing on a Hungarian County}, url = {https://m2.mtmt.hu/api/publication/34478440}, author = {Szabó, Károly and Szabó, László and Kása, Richárd}, doi = {10.3390/logistics8010007}, journal-iso = {LOGISTICS-BASEL}, journal = {LOGISTICS (BASEL)}, volume = {8}, unique-id = {34478440}, abstract = {Background: Despite the fact that some results can be found for the logistics simulation in the literature, there is a lack of an experiment based on inner company data. Therefore, the study aimed to determine the potential need for this kind of solution by Zala County enterprises. Methods: As a first step, the paper presents the existing literature with the help of a literature review. Afterwards, questionnaire sampling was conducted among local enterprises. The paper applies several statistical methods (e.g., descriptive statistics, SPSS, exploratory factor analysis, and structural equation modeling) to the sample for the validation of the reorganization demand. Results: The study obtained a total of 147 complete responses from the 1022 invitations. An overwhelming majority of the respondents indicated regular and significant delays in their logistics processes, as well as the need for a new simulation method. Based on the SEM model, it has been observed that IT solutions are being utilized in an inefficient manner, resulting in logistical system issues and operational damages. Conclusion: The paper successfully identified a research gap, the research of which can have not only theoretical but also many practical benefits. Hopefully, the results will generate other academic research in this field.}, year = {2024}, eissn = {2305-6290}, pages = {7}, orcid-numbers = {Szabó, László/0000-0003-4153-8432; Kása, Richárd/0000-0002-2621-8396} } @book{MTMT:34698169, title = {L-I-M logisztika-informatika-menedzsment nemzetközi tudományos konferencia}, url = {https://m2.mtmt.hu/api/publication/34698169}, isbn = {9786156342775}, editor = {Gubán, Miklós and Szabó, László and Kása, Richárd}, publisher = {Budapesti Gazdasági Egyetem Pénzügyi és Számviteli Kar Gazdaságinformatika Tanszék}, unique-id = {34698169}, year = {2024}, orcid-numbers = {Gubán, Miklós/0000-0001-7416-2406; Szabó, László/0000-0003-4153-8432; Kása, Richárd/0000-0002-2621-8396} } @inproceedings{MTMT:35068143, title = {Greenwashing in Logistics}, url = {https://m2.mtmt.hu/api/publication/35068143}, author = {Szabó, László and Udvaros, József and Forman, Norbert and Tasic, Jelena}, booktitle = {XIV International Symposium ENGINEERING MANAGEMENT AND COMPETITIVENESS (EMC 2024)}, unique-id = {35068143}, abstract = {As global systems evolve, logistics plays a major role in the movement of goods and the operation of supply chains.

This study explores how QR codes can be integrated into e-commerce systems, with a focus on shipping and logistics processes. The use of QR codes enables accurate tracking of products from order to delivery, thus increasing transparency and reducing the occurrence of errors. Customers can track the status of their orders in real time using QR codes, which improves customer experience and satisfaction. In the area of warehouse management, QR codes provide quick access to inventory data, which significantly increases the efficiency of work processes. In addition, the use of QR codes in inventory identification and management enables the implementation of automatic data entry and inventory updating, which reduces administrative burdens and minimizes the possibility of human error. The study points out that the use of QR codes not only enables the improvement of current systems, but also offers new opportunities for the development of intelligent logistics solutions. Overall, the introduction of QR codes into e-business logistics and order tracking processes is an innovative step that can provide companies with a sustainable competitive advantage in the long term.}, keywords = {logistics; e-Business; QR Code; Order tracking}, year = {2024}, pages = {275-280}, orcid-numbers = {Forman, Norbert/0009-0000-1974-8308; Tasic, Jelena/0009-0001-8524-1668; Szabó, László/0000-0003-4153-8432} } @inproceedings{MTMT:35469466, title = {Recognize and decode QR codes from images*}, url = {https://m2.mtmt.hu/api/publication/35469466}, author = {Udvaros, József and Szabó, László}, booktitle = {2024 10th International Conference on Control, Decision and Information Technologies (CoDIT)}, doi = {10.1109/CoDIT62066.2024.10708606}, unique-id = {35469466}, year = {2024}, pages = {1393-1397}, orcid-numbers = {Szabó, László/0000-0003-4153-8432} } @article{MTMT:35645989, title = {The role of IT projects within the strategy: How effectively do we use them?}, url = {https://m2.mtmt.hu/api/publication/35645989}, author = {Szabó, Károly and Szabó, László}, doi = {10.5937/JEMC2402125S}, journal-iso = {JEMC}, journal = {JOURNAL OF ENGINEERING MANAGEMENT AND COMPETITIVENESS}, volume = {14}, unique-id = {35645989}, issn = {2334-9638}, abstract = {It is a general trend that the role of projects is increasingly appreciated in the life of individual organizations.
