This research aims to design and develop an efficient and integrated website-based Point of Sales (POS) system for Kamala Bali Resort in Nusa Dua, in order to improve operational efficiency and service quality. The method used is a qualitative approach, which includes in-depth interviews, direct observation, and document analysis to understand the needs and challenges faced by the resort in managing the transaction system. The results showed that the development of a website-based POS system that integrates the Front Office Cashier (FOC) and Restaurant Bar Cashier (RBC) modules can accelerate the guest registration process, food and beverage order management, and real-time financial transaction management. The system also reduces the risk of human error and increases the transparency of financial reports. The contribution of this research is not only to provide practical solutions for small and medium-sized hotels in adopting technology, but also to enrich the literature regarding the application of information systems in the hospitality industry, as well as to become a model for other hotels in Indonesia that want to transform into the digital era.
This study evaluated the performance of graduates from the Diploma in Hotel and Restaurant Technology program at Data Center College of the Philippines, Bangued, Abra. Utilizing the Input-Process-Output (IPO) framework, the research examined graduate profiles, performance levels across competencies, adequacy of training resources, and the challenges encountered in their transition to the workforce. Results revealed that graduates demonstrated excellent performance in competencies such as Food and Beverage Services NCII and Cookery NCII, while Bartending NCII exhibited room for improvement. Training tools and equipment were generally adequate, although enhancements were recommended for Food and Beverage Services NCII. Socioeconomic background significantly influenced performance in select competencies, while other demographic factors showed minimal impact. Key challenges identified included a mismatch between theoretical training and industry demands, limited hands-on experience, and inadequate support systems. The Competency-Based Learning Materials (CBLM) were validated as highly effective but required refinements to align better with industry expectations. Recommendations included curriculum revisions to integrate experiential learning, enhanced training modules for underperforming competencies, strengthened industry partnerships, improved resource allocation, and the establishment of mentorship and support programs. These findings underscore the importance of aligning academic programs with industry needs to equip graduates with the competencies and resilience needed to succeed in the hospitality sector.

There is a growing interest in leveraging multiple large language models (LLMs) for automated code optimization. However, industrial platforms deploying multiple LLMs face a critical challenge: prompts optimized for one LLM often fail with others, requiring expensive model-specific prompt engineering. This cross-model prompt engineering bottleneck severely limits the practical deployment of multi-LLM systems in production environments. We introduce Meta-Prompted Code Optimization (MPCO), a framework that automatically generates high-quality, task-specific prompts across diverse LLMs while maintaining industrial efficiency requirements. MPCO leverages metaprompting to dynamically synthesize context-aware optimization prompts by integrating project metadata, task requirements, and LLM-specific contexts. It is an essential part of the ARTEMIS code optimization platform for automated validation and scaling. Our comprehensive evaluation on five real-world codebases with 366 hours of runtime benchmarking demonstrates MPCO's effectiveness: it achieves overall performance improvements up to 19.06% with the best statistical rank across all systems compared to baseline methods. Analysis shows that 96% of the top-performing optimizations stem from meaningful edits. Through systematic ablation studies and meta-prompter sensitivity analysis, we identify that comprehensive context integration is essential for effective meta-prompting and that major LLMs can serve effectively as meta-prompters, providing actionable insights for industrial practitioners.
Community Question Answering (CQA) platforms can be deemed as important knowledge bases in community, but effectively leveraging historical interactions and domain knowledge in real-time remains a challenge. Existing methods often underutilize external knowledge, fail to incorporate dynamic historical QA context, or lack memory mechanisms suited for industrial deployment. We propose ComRAG, a retrieval-augmented generation framework for real-time industrial CQA that integrates static knowledge with dynamic historical QA pairs via a centroid-based memory mechanism designed for retrieval, generation, and efficient storage. Evaluated on three industrial CQA datasets, ComRAG consistently outperforms all baselines--achieving up to 25.9% improvement in vector similarity, reducing latency by 8.7% to 23.3%, and lowering chunk growth from 20.23% to 2.06% over iterations.
Methods. Using the methods of analysis and synthesis, a detailed analysis of literary sources, scientific articles and practical cases related to marketing communications in the hospitality sector was carried out. The results obtained were synthesized to form a generalized picture of the state of personalization in the industry. The grouping method was used to systematize marketing communications personalization tools by types of communication channels (CRM systems, mobile applications, loyalty programs, etc.). The study was carried out using a systems approach, which allowed us to consider personalized marketing communications as a complex process that includes data collection, customer segmentation, creation of personalized offers and their implementation through various communication channels. Results. It is proven that thanks to the rapid development of digital technologies, the hotel and restaurant industry is introducing innovations such as online booking, mobile applications, automation of service processes, as well as personalized services, which allows to increase the level of customer satisfaction and loyalty. A detailed study of personalized marketing communications tools in the hotel and restaurant business has been carried out. It has been proven that personalized marketing communications are a powerful tool for increasing customer engagement and increasing sales, allowing to create an individual experience for each client, which helps strengthen the brand, increase its competitiveness and long-term consumer loyalty. Novelty. The author's definition of the essence of personalized marketing communications in the hotel and restaurant business is proposed as the process of creating individual marketing messages and offers for specific customers or audience segments based on their preferences, behavior, previous purchases and other collected information. Also, the novelty lies in the development of the author's methodology for personalizing marketing communications, which includes a comprehensive approach to data collection, segmentation, analysis and implementation of personalized offers. The proposed methodology allows you to increase the competitiveness of hotel and restaurant businesses. The practical value of the study lies in the possibility of using the developed methodology by enterprises of the hotel and restaurant business to increase the level of customer loyalty, increase revenues and improve reputation in the market. The methodology can be adapted for different market segments and business scales, which makes it universal for use in modern competition.
The article discusses the issues of tourism cluster development in the Kakheti region as a priority direction for increasing the economic growth of the region. It is mentioned that the economic development of the Kakheti region is one of the main priorities as for the region, as for the country in general. Recently, initiatives implemented by the state support the development of clusters, that is, the creation of business clusters, which allow small and medium-sized companies to make partnership with other businesses representing the same industry to become more competitive and create more jobs. Development of a market-oriented cluster and introduction of a pilot model will unite the thematic cluster in the tourism sector. for example, in the local wine and gastronomic tourism cluster of Kakheti, local food producers, wine enterprises that offer tourist and hotel services to customers, restaurants and family hotels that sell local culinary products will be united. Also, wine bars and sector associations; clusters lead to a new perspective about the economy and its development, the role of cooperation of business, government and institutions. Our study region, Kakheti, has great potential for tourism development. It has a unique, natural, complex and rich cultural heritage, which is a solid foundation for a sustainable economy, raising the standard of living of the population and ensuring long term social and economic development. For the Kakheti region, the development of tourism contributes to the development of small businesses and is an important source of attracting foreign investments. Tourism proportionally contributes to the development of other sectors as well. The rise of tourism in the region is one of the most important factors in raising the standard of living of the population, strengthening the tourism potential and establishing a modern industry in the region. According to the reports of the National Tourism Administration of Georgia and Geostat.ge, the Kakheti region plays an important role in the tourism sector, which is confirmed by the surveys of visitors and tourist companies and the increase in direct investments. The attractiveness of modern tourism is the unique impressions received during the trip. That is why Kakheti is identified with the most important phenomena of Georgia, such as: - "the homeland of wine", the birthplace of "Kvevri wine"(recognized by UNESCO as a world intangible heritage). We have to consider the Caucasus Mountains with unique scenery: the highlands of the Eastern Caucasus, where medieval architecture and harmonious examples of coexistence with nature are still preserved; Ancient archaeological finds, magnificent examples of pre-Christian and medieval architecture and a living tradition of monastic life; special landscapes and unique biodiversity preserved in national parks (Lagodekhi, Tusheti, Vashlovni national parks); Ultimately, Kakheti is characterized by three main tourist attraction factors: (1)historical and cultural heritage and its knowledge; (2) Unrepeatable nature and adventure travel and (3) Wine and the tradition of hospitality. Tourism is quite competitive industry. Therefore, the development of a tourism requires appropriate local infrastructure, logistics, transport communication, safety and healthy living conditions, competitive prices and, most importantly, service area- skills of staffs. In this regard, several urban nodes have been established in the region from the point of view of tourism - Telavi, Kvareli, Sighnaghi, Akhmeta. Small villages, chains of wineries and hotels, and recreational spaces are actively developing around these junctions (for example: around Telavi - the villages of Vardisubani, Ikalto, Tsinandali; around Kvareli - Ilia Lake, Kvareli Lake, Lopota; around Sighnaghi - the villages of Nukriani, Kedel, Anaga, Bodbes historical-cultural complex). This Trend is quite positive and natural. Considering the perspective of tourism development, it is important that the region can develop its logistics functions: transport hubs - hotel/accommodation center (it is necessary to transform existing buildings into small family hotels and create new buildings of the appropriate scale), it is necessary to invest in new medium (maximum 40 rooms) and small (15-20 rooms) for the construction of shelters. Beyond the historical centers of Kakheti, restaurants and food facilities, shopping and entertainment facilities should be developed on the outskirts, shopping spaces in the city center should be organized. This process is a precondition for cluster formation in tourism sectors. In relation to the latter, emphasis should be placed on the development of local production. There are resources for this and companies must be promoted. In the direction of tourism, it is desirable to create three thematic clusters in Kakheti, (1)a cluster of local wine and gastronomic tourism, (2) a cluster of authentic hotels and a (3) cluster of cultural heritage, where entrepreneurs and organizations providing relevant products and services will unite. Specific activities include familiarization with international standards, development of opportunities in the areas of marketing and online presentation, etc. Thus, as the research showed, the effective functioning of clusters depends on the distance between the groups included in it and the influence of variables. Clusters are not equally sensitive to variables. They differ in risk. The latter indicates that dividing the cluster into groups will give qualitative results. Depending on its nature, risks will be distributed among the groups, the priority of each will be identified and used as much as possible, which is necessary for the continuity of the processes in the cluster. In the end, with all of the above, it will be possible to use the export potential of the region in a targeted manner and develop the economy of the region/country in a sustainable way. The use of the cluster model in the conditions of the pandemic (and not only) will be one of the strong levers for the rapid development and full use of the national economic potential, both for the regions and for the country as a whole. Keywords: tourism, tourism cluster, regional economy, state policy.

As a tech company, Grab has expanded from transportation to food delivery, aiming to serve Southeast Asia with hyperlocalized applications. Information about places as transportation destinations can help to improve our knowledge about places as restaurants, so long as the spatial entity resolution problem between these datasets can be solved. In this project, we attempted to recognize identical place entities from databases of Points-of-Interest (POI) and GrabFood restaurants, using their spatial and textual attributes, i.e., latitude, longitude, place name, and street address. Distance metrics were calculated for these attributes and fed to tree-based classifiers. POI-restaurant matching was conducted separately for Singapore, Philippines, Indonesia, and Malaysia. Experimental estimates demonstrate that a matching POI can be found for over 35% of restaurants in these countries. As part of these estimates, test datasets were manually created, and RandomForest, AdaBoost, Gradient Boosting, and XGBoost perform well, with most accuracy, precision, and recall scores close to or higher than 90% for matched vs. unmatched classification. To the authors' knowledge, there are no previous published scientific papers devoted to matching of spatial entities for the Southeast Asia region.
Introduction. Strategic management in the HoReCa industry is essential for success, but it becomes even more challenging during times of war. The state of war affects the socio-economic situation and poses new challenges for hotels and restaurants. Recent research and publications highlight the interest in understanding the impact of war on HoReCa's strategic management. Addressing this issue requires developing adaptive strategies, ensuring safety for staff and guests, and maintaining business stability and productivity. The purpose of the paper is to define the concept of "HoReCa sphere", to identify the features of strategic management in the HoReCa sphere and to study the impact of martial law on strategic management in the hotel and restaurant business. Results. The term "HoReCa" has gained wide acceptance in the commercial hospitality industry. It encompasses a variety of establishments engaged in the production and sale of food for immediate consumption away from home, primarily hotels, restaurants and catering services. Strategic management in the HoReCa sector plays a crucial role in achieving competitive advantage and ensuring the sustainable development of enterprises in this industry. The strategic management cycle consists of four stages, including analysis of the external environment, formulation of the mission and strategic goals, selection of strategies and their implementation with control. The success of HoReCa businesses depends on flexibility, responsiveness to market changes, a customer-oriented approach and the development of competitive advantages, such as quality service, professionalism and positive community relations. Strategic management in the HoReCa sector is essential for navigating the dynamic and competitive environment of the hospitality industry. In times of military conflict, strategic analysis and planning must take into account unique circumstances, including risk assessment, conservation of resources, adaptation to changing customer behaviour and expectations, and adjustments to supply chains due to the constraints and challenges of the conflict situation. Conclusion. Overall, strategic management plays a vital role in the success and resilience of HoReCa businesses, especially in times of war, enabling them to respond effectively to market demands and maintain a positive reputation in the community.
Due to border closures during the COVID-19 pandemic, the hospitality and tourism industry was given a chance to re-imagine and re-invent itself. New Zealand’s borders were shut to international tourists for 28 months, giving it a considerable amount of time to strategise about what the future of tourism would be. One of these strategies was to attract more desirable tourists. New Zealand was not alone in this pursuit: other countries wanted to move towards a more sustainable tourism model, attracting high-value tourists instead of the default of mass tourism that popular destinations had suffered from. This conceptual article discusses how Tourism New Zealand started to re-imagine luxury hospitality to encourage high-value tourists to come to New Zealand.

We propose an IoT energy service provisioning framework to ensure consumers' Quality of Experience (QoE). A novel context-aware trust assessment model is proposed to evaluate the trustworthiness of providers. Our model adapts to the dynamic nature of energy service providers to maintain QoE by selecting trustworthy providers. The proposed model evaluates providers' trustworthiness in various contexts, considering their behavior and energy provisioning history. Additionally, a trust-adaptive composition technique is presented for optimal energy allocation. Experimental results demonstrate the effectiveness and efficiency of the proposed approaches.

Cellular Vehicle-to-Everything (C-V2X) is currently at the forefront of the digital transformation of our society. By enabling vehicles to communicate with each other and with the traffic environment using cellular networks, we redefine transportation, improving road safety and transportation services, increasing efficiency of vehicular traffic flows, and reducing environmental impact. To effectively facilitate the provisioning of Cellular Vehicular-to-Network (C-V2N) services, we tackle the interdependent problems of service task placement and scaling of edge resources. Specifically, we formulate the joint problem and prove that it is not computationally tractable. To address its complexity we propose Deep Hybrid Policy Gradient (DHPG), a new Deep Reinforcement Learning (DRL) approach that operates in hybrid action spaces, enabling holistic decision-making and enhancing overall performance. We evaluated the performance of DHPG using simulations with a real-world C-V2N traffic dataset, comparing it to several state-of-the-art (SoA) solutions. DHPG outperforms these solutions, guaranteeing the $99^{th}$ percentile of C-V2N service delay target, while simultaneously optimizing the utilization of computing resources. Finally, time complexity analysis is conducted to verify that the proposed approach can support real-time C-V2N services.
The article is devoted to analyzing the current state of the global franchise market and the study of problems, trends, and prospects for its development. The study’s primary purpose is to substantiate the impact of the franchise market on the development of the hospitality sector. The study results show that today the franchise market is developing rapidly, with the most active in the hospitality industry, formed by the hotel and restaurant business. Today the franchise market is most actively developing in fast food. Analysis of the development trend in recent years has shown a significant market decline in 2020 due to the pandemic. It proves that the franchise market is a driver of the development of the hospitality industry, as the growth rate of income of companies that work in franchises exceeds the total income of companies in the hospitality industry. At the same time, the impact occurs not only in the economic aspect but also in the social one. Franchising is a stimulant for employment growth. It also helps to improve the quality of services and stimulates the development of small businesses. The paper also summarizes the main discussion issues of the positive impact of franchising in the hospitality sector. The primary trend in market development is the digitalization of tourism technology.
The aim of the article is to identify the main features of hospitality, their manifestations, and their significance for the development of the accommodation and catering industry from ancient times to the present in the European and Ukrainian contexts. The research methodology is based on the use of general scientific (analytical and synthetic, inductive and deductive) and special historical (historical-comparative, problem-chronological, retrospective, diachronic) methods. Analytical and synthetic methods were used in identifying individual facts, phenomena, trends, and their further systematization in a logical sequence to argue certain assumptions, statements, and conclusions. Special historical methods were used in the process of highlighting the facts related to the development of hospitality in their chronological order and in comparison between different regions of the world to identify common trends. Results. The formation of hospitality traditions began with the first cultural and economic communications between representatives of different communities. These traditions included respect for the guest and providing him with the necessary safe living conditions. Over time, the elements of hospitality have become the basis of an extensive and profitable industry, which includes not only accommodation and food, but also entertainment and leisure, but such changes have occurred relatively recently, with the transformation of tourism into a mass phenomenon. Hospitality has played in the past and continues to play an important role in preserving and restoring national identity. Ukrainian national identity, which is changing very slowly and imperceptibly for its bearers, is becoming one of the features of the national character and includes elements of traditional folk hospitality. The history of the development of accommodation and catering shows the important role of hospitality as an integral factor of intercultural communication both in ancient times and in the modern world. Victory in the modern market of tourist services is possible only based on taking into account the historical specifics of traditional folk hospitality and its combination with today's trends in the hospitality industry. The scientific novelty is to determine the features of hospitality and their implementation in accommodation and catering establishments over a long time in comparison with the European and Ukrainian experiences. The practical significance is to draw the attention of the hotel and restaurant industry to the importance of hospitality, which has become an essential component of a successful business element.
The first epidemic of the modern world that has changed the course of the current civilization & turned out to be a pandemic (i.e. COVID-19) has tremendously affected several industries including that of tourism & hospitality. Due to the multilevel impact, the whole world struggled to overcome this situation but with almost two years of its co-existence, people have now managed to change their style of living & social habits including that of the food habits. One of such food habits i.e. 'Eating out/ Dining out' was bound to change in the post-pandemic period due to the health advisories & closure of several hotels, restaurants and food outlets. The present research tries to find out the changes in the Eating out behaviour of the residents of Dharamshala (H.P.) in the pre & post-pandemic period. Further, it tries to identify the factors which affect the eating out behaviour of the residents & measure their importance in different periods (pre &post pandemic). The data were collected from 286 residents of Dharamshala region, through a structured questionnaire & analysed through reliability checks (Cronbach's Alpha-α), KMO & Bartlett’s test, factor analysis, paired sample t-test and analysis of frequency & mean values. The results showed a significant decrease in the frequency of visits, purchasing/ordering, percentage of outside meals consumed, average spending etc, whereas the level of priority given by the residents to hygiene, food safety, quality, service & distribution etc has increased in the post-pandemic period. Hence various strategies were suggested for the restaurants/local eateries like, (1) Use of technology (automatic doors, sensor & timer enabled soap & sanitiser dispenser, online payments), (2) cost reduction tactics (controlling of food wastage, reduction in menu items), (3) training of employees (sanitisation rules, HACCP rules) etc which were if adopted will certainly help them revive from the crisis slowly & steadily over the period.
Topicality.The popularity of coffee industry is high. This business is actively developing in Ukraine. A coffee shop is an establishment where the high quality of the product, as well as the development of coffee consumption culture are always in the first place. An important component is the commercial activity on which the coffee industry is built. This is an indicator of the right culture: more often Ukrainians prefer coffee in some cafe or restaurant, or even takeaway, instead of home or office coffee. However, COVID 19 pandemic affected the decrease in visits by Ukrainians to coffee shops, cafes, restaurants and other catering establishments. The main share of coffee consumption is an imported product. Ukrainian production is formed by manufacturers who import coffee beans as a raw material, and in Ukraine they roast, receive, package, produce an article without caffeine, and sell it under their own brand. The fiercest competition is typical in low segments of coffee drinks and grains.
The aim of the study and its methods. The purpose of this article is to analyse the current state of Ukrainian coffee industry. When conducting the research, general scientific methods have been applied: scientific and theoretical elaborations of blighty and foreign scientists, informational materials of statistical and reference publications, analysis, synthesis, generalisation, comparison.
Results. The article analyses the current state of coffee industry in Ukraine. The greatest producers of coffee and the most popular brands of grain and ground coffee in Ukraine have been characterised. The structure of coffee consumption in Ukraine by types and in quantitative indicators has been analysed. It has been noted that Ukrainian coffee industry is represented by a large number of small operators who open their mobile coffee shops in places with high traffic. This is due to small initial investments, a short payback period, and the possibility to change the location. Since the tendencies of the world coffee market have a significant impact on coffee industry in Ukraine, the demand is also growing steadily. The amount of coffee import in Ukraine exceeded the volume of exports. In 2020, the scope of export reached 15,0 million dollars, USA, while in 2021 it increased to 15,9 million dollars, USA. The amount of import increased from 251,3 million dollars, USA in 2020 to 266,7 million dollars, USA in 2021. The import of coffee beans is aimed at meeting domestic consumers’ needs. Ukraine is completely dependent on import, due to the non-compliance with natural and climatic conditions, because growing coffee on the territory of Ukraine is impossible.
Conclusions and discussion. So, in the course of this study, it has been established that coffee industry in Ukraine is developing more actively and even creating competition. A significant place in the restaurant industry is occupied by coffee shops, which increase competition and increase the quality of provided services. Modern coffee shops are restaurant establishments where coffee is made at a new level, with an individual approach to each guest. The current types of restaurant industry establishments are multi-format, so the creation of a national coffee shop is one of the advertising means of our country. Cafes with 3–4 seats are gaining popularity in Kyiv. On the other hand, recently, popular “to go” coffee shops are losing their market key positions. The market of coffee industry is going to grow, and become saturated after the end of the full-scale war. The infrastructure is going to be restored, and the restaurant industry has all the chances to be developed in the eastern region of Ukraine.

With the advent of smart industry, Industrial Control Systems (ICS) are increasingly using Cloud, IoT, and other services to meet Industry 4.0 targets. The connectivity inherent in these services exposes such systems to increased cybersecurity risks. To protect ICSs against cyberattacks, intrusion detection systems and intrusion prevention systems empowered by machine learning are used to detect abnormal behavior of the systems. Operational ICSs are not safe environments to research intrusion detection systems due to the possibility of catastrophic risks. Therefore, realistic ICS testbeds enable researchers to analyze and validate their intrusion detection algorithms in a controlled environment. Although various ICS testbeds have been developed, researchers' access to a low-cost, adaptable, and customizable testbed that can accurately simulate industrial control systems and suits security research is still an important issue. In this paper, we present ICSSIM, a framework for building customized virtual ICS security testbeds, in which various types of cyber threats and attacks can be effectively and efficiently investigated. This framework contains base classes to simulate control system components and communications. ICSSIM aims to produce extendable, versatile, reproducible, low-cost, and comprehensive ICS testbeds with realistic details and high fidelity. ICSSIM is built on top of the Docker container technology, which provides realistic network emulation and runs ICS components on isolated private operating system kernels. ICSSIM reduces the time for developing ICS components and offers physical process modelling using software and hardware in the loop simulation. We demonstrated ICSSIM by creating a testbed and validating its functionality by showing how different cyberattacks can be applied.

In this paper, we propose revisited versions for two recent hotel recognition datasets: Hotels50K and Hotel-ID. The revisited versions provide evaluation setups with different levels of difficulty to better align with the intended real-world application, i.e. countering human trafficking. Real-world scenarios involve hotels and locations that are not captured in the current data sets, therefore it is important to consider evaluation settings where classes are truly unseen. We test this setup using multiple state-of-the-art image retrieval models and show that as expected, the models' performances decrease as the evaluation gets closer to the real-world unseen settings. The rankings of the best performing models also change across the different evaluation settings, which further motivates using the proposed revisited datasets.

Food delivery systems are gaining popularity recently due to the expansion of internet connectivity and for the increasing availability of devices. The growing popularity of such systems has raised concerns regarding (i) Information security, (ii) Business to business (B2B) deep discounting race, and (iii) Strict policy enforcement. Sensitive personal data and financial information of the users must be safeguarded. Additionally, in pursuit of gaining profit, the restaurants tend to offer deep discounts resulting in a higher volume of orders than usual. Therefore, the restaurants and the delivery persons fail to maintain the delivery time and often impair the food quality. In this paper, we have proposed a blockchain and smart contract-based food delivery system to address these issues. The main goal is to remove commission schemes and decrease service delays caused by a high volume of orders. The protocols have been deployed and tested on the Ethereum test network. The simulation manifests a successful implementation of our desired system; with the payment being controlled by our system. The actors (restaurant, delivery-person or consumer) are bound to be compliant with the policies or penalized otherwise.
