The article substantiates a methodological approach to modelling the sustainable AI transformation of a hotel enterprise. The study distinguishes between the enterprise’s digital sustainability capability, the net effect of a specific AI solution, and the intensity of its actual use in business processes. Digital Sustainability Capability is interpreted as the enterprise’s ability to convert digital infrastructure, integrated data, analytical tools and organisational competencies into decisions that improve economic, environmental and social performance. AI intensity is represented through the coverage of a business process, the autonomy of the AI solution and the frequency of its actual use. A system for assessing the Net AI Sustainability Effect is proposed, combining economic, environmental and social outcomes while treating governance requirements as non-compensatory admissibility constraints. To determine the economically justified depth of AI integration, a model of net economic value is developed that incorporates the direct automation effect, the nonlinear transformation effect of business-process redesign, digital capability, human intensity of the process, implementation costs and the potential benefits of transformation. The sustainable level of AI intensity is defined by reconciling the economic optimum with environmental, social and governance limits. The model also separates the decision to enter an AI project from the decision on how intensively the technology should be used after implementation. To analyse the adjustment process, a discrete dynamic model is proposed in which AI intensity changes in response to the marginal economic effect, while the adjustment factor reflects the inertia of boundary states. Conditions for local stability and the critical speed of managerial adjustment are derived. A numerical illustration of the model is provided using a hypothetical scenario of AI-supported optimisation of a hotel heating, ventilation and air-conditioning system. The results show that maximum AI intensity is not necessarily economically optimal, while excessive adjustment speed may destabilise the system and generate periodic regimes. The proposed approach provides a framework for selecting an economically justified and sustainability-compatible depth of AI transformation in hotel business processes.Keywords: hotel, digital capability, sustainable development, AI-transformation, bifurcation.
The article is devoted to the development of a methodology for assessing the multiplier and synergistic effects of integrating waste-to-energy (WTE) projects into the circular economy system. The relevance of the study is determined by the need for a comprehensive assessment of the performance of energy recovery from waste, taking into account economic, resource, energy, environmental, and social effects. A methodological approach is proposed that combines the assessment of the direct outcomes of WTE projects with the evaluation of the effects arising from their interaction with other components of the circular economy. The multiplier effect is defined as the result of the transmission of primary economic impulses to related economic activities through increases in value added, employment, investment, as well as resource and energy flows. The synergistic effect is interpreted as an additional outcome generated through the coordinated interaction of WTE projects with waste sorting, reuse, recycling, and resource recovery systems. The methodology provides for the development of a system of indicators, normalization of input data, determination of weighting coefficients, and calculation of an integrated efficiency index. The scientific novelty lies in the comprehensive consideration of the interrelated components of the effects generated by WTE project integration. The practical significance of the proposed approach lies in its applicability to the comparative assessment of alternative projects, the substantiation of investment decisions, and the identification of priority areas for the development of the circular economy.Keywords: waste-to-energy, circular economy, multiplicative effect, synergistic effect, efficiency assess-ment, project integration, waste, energy recovery, resource efficiency, economic efficiency.
The article substantiates the integration of adaptive design and project management as instruments for strengthening the brand and team resilience of logistics companies under economic and security instability. The relevance of the study is determined by wartime risks, damage to transport and energy infrastructure, changing transport routes, personnel shortages, business relocation, and uneven digital maturity in Ukraine’s logistics sector. The purpose of the article is to develop a conceptual model that integrates adaptive brand design, flexible project-management tools, and practices for building team resilience. The study employs critical review and systematization of scholarly sources, content analysis of logistics-related materials, comparative analysis of conventional and flexible management approaches, and conceptual modelling. Adaptive design of a logistics project is defined as a system of modular visual-communication, process, and role-based solutions that preserves brand coherence and team manageability when external constraints, operational scenarios, communication channels, or team composition change. The proposed model links instability factors with adaptive design, flexibility of project processes, team resilience, consistency of brand communication, customer trust, and brand recognition. It distinguishes the stable core of brand identity from variable communication elements and combines this distinction with scenario planning, distribution of critical roles, knowledge sharing, and feedback. Practical recommendations include developing a modular brand identity system, identifying and backing up critical roles, documenting knowledge, using short planning cycles and retrospectives, and applying digital monitoring tools. The suggested approach can support continuity of communication and project activity, reduce reliance on individual employees, improve the timeliness of managerial responses, and create conditions for the adaptation of logistics teams. Further research should empirically test the model using a sample of Ukrainian transport and logistics companies. It establishes indicators for monitoring brand consistency, knowledge availability, and the response time of project processes during disruptions and staffing changes in practice.Keywords: adaptive design, project management, logistics companies, brand identity, brending, team resilience, organizational resilience, agile approaches.
The theoretical foundations for the formation of a regenerative tourism ecosystem as an innovative model for the development of sustainable regional entrepreneurship based on adaptive tourism products are substantiated, and an original model of its functioning under post-war recovery conditions is developed. The evolution of conceptual approaches in tourism studies – from sustainable and responsible tourism to circular and regenerative tourism – is examined. It is demonstrated that the regenerative approach substantially expands the sustainable development paradigm: it involves not only minimizing negative anthropogenic impacts, ensuring the rational use of resources, and maintaining ecological balance, but also actively restoring, enriching, and revitalizing the natural, cultural, social, and human capital of tourist destinations. It is demonstrated that adaptive tourism products acquire strategic importance in the context of post-war recovery. They are defined as a combination of tourism services, facilities, and digital solutions designed according to the principles of universal design, flexible personalization, and inclusivity. It is substantiated that such products are aimed at meeting the needs of a broad range of consumers, including war veterans, internally displaced persons, persons with disabilities, older adults, and individuals experiencing post-traumatic disorders. They can be effectively integrated with physical and psychological rehabilitation programs, gastrotherapy, wellness and health promotion, cultural adaptation, and social inclusion initiatives. An original conceptual model of a regenerative tourism ecosystem for the Kharkiv region is proposed, viewing tourism as an integrated socio-economic system comprising six interrelated components: the resource, entrepreneurial, innovation, adaptive, partnership, and outcomes components. The scientific novelty of the study lies in identifying the adaptive component as an independent element of the ecosystem, enabling the synergistic integration of the economic, social, and humanitarian objectives of territorial development. It is demonstrated that the functioning of such an open, multilevel system based on cross-sectoral partnerships among businesses, public authorities, universities, international foundations, and local communities will contribute to stimulating the local economy, diversifying entrepreneurial activity, creating new jobs, enhancing the competitiveness of destinations, and strengthening long-term regional resilience.Keywords: regenerative tourism; regenerative tourism ecosystem; sustainable tourism; circular tourism; sustainable entrepreneurship; adaptive tourism products; regional development, tourism destination
The article examines the logistics resilience of Ukraine under conditions of war risks and identifies the key factors ensuring the continuity of the national transport and logistics system during the full-scale war. The relevance of the research is determined by the profound transformation of logistics processes caused by the destruction of transport infrastructure, the disruption of traditional transport routes, changes in the geography of foreign trade, and the urgent need to establish alternative logistics chains. The paper summarizes contemporary scientific approaches to the interpretation of logistics resilience and substantiates its consideration as an integrated characteristic of the transport and logistics system reflecting its ability to ensure the continuity of logistics processes, adapt to changes in the security environment, and maintain the functioning of international freight flows. The current state of Ukraine's transport and logistics system is analyzed on the basis of statistical indicators of foreign trade during 2021-2025. The findings indicate that despite the dramatic decline in export activity in 2022, Ukraine's transport and logistics system gradually adapted to the new operating environment. This adaptation was facilitated by the development of alternative transport routes, the operation of the Ukrainian Maritime Corridor, the diversification of logistics channels, and the deeper integration of Ukraine's transport system into the European logistics area. At the same time, the study demonstrates that the current stage of logistics development is characterized by the transformation of war-related risks manifested in systematic attacks on port infrastructure and civilian shipping, increasing logistics and insurance costs, and growing pressure on alternative transport routes. The research identifies the key factors ensuring Ukraine's logistics resilience, including the diversification of transport and logistics routes, the development of multimodal transportation, the integration of the national transport system into the European logistics area, the adaptability of logistics market participants, and international support for transport infrastructure development. It is substantiated that the integrated interaction of these factors ensures the continuity of international logistics links, the stability of foreign trade transportation, and the resilience of Ukraine's transport and logistics system under prolonged wartime conditions.Keywords: logistics, logistical sustainability, transport and logistics system, military risks, transport cor-ridors, logistical routes.
