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.

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.

However, sustainability is increasingly becoming a priority for companies and society. Integrating this into logistics processes is a major challenge. Sustainability in logistics is important not only from an environmental perspective, but also in its economic and social dimensions. Here we should mention the concept of green logistics. The public exploitation of the benefits of green logistics helps companies to attract customers, although in many cases greenwashing can also be encountered. In this paper, we focus on the role of greenwashing.

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.

We have come to the point in the last decade where certain organizations use this method for their entire operation, while large companies implement their priority developments only with project management methods. The project management knowledge is becoming progressively essential also in the case of smaller businesses nowadays as they come into contact with projects through their partners or their own experiences. Although the methodology is constantly spreading and growing, so far, there have been just a few scientific results about where IT projects are located in the organization's goal-system and how they are related to the corporate or organizational strategy. Accordingly, the basic goals of the IT projects will be examined in the framework of the current research, and the questions about that, are these goals related to the corporate strategy and how effective are the individual companies using their IT projects?

A blokklánc potenciálisan átalakíthatja a termelői és logisztikai műveleteket, javíthatja az átláthatóságot és a biztonságot, valamint csökkentheti az adminisztratív terheket. A világ fejlett régiói sokat tesznek az élelmiszerbiztonság javítása érdekében, azonban az integráció nem történik zökkenőmentesen. Egy informatikai rendszer önmagában nem tud mindent megváltoztatni. Az eredményes változáshoz megfelelő jogszabályok szükségesek. A kutatásban az Európai Unió és Magyarország került a fő fókuszba. Az Európai Unió élelmiszerbiztonságot érintő jogi szabályozása alapkövét képezheti egy határokon átívelő biztonságos rendszer kialakításának. Ebben a tanulmányban mind vállalati, mind felhasználói oldalról megvizsgáltuk a blokklánc magyarországi helyzetét az élelmiszeriparra fókuszálva. Egyfelől vállalati interjú készítésével, másfelől kérdőíves felmérés segítségével.
