    Service-based, Multi-Provider, Fog Ecosystem with Joint Optimization of Request Mapping and Response Routing

    Digital transformation is increasingly reliant on service -based operations in fog networks. The latter is a geo-dispersed form of the cloud, extending resources closer to end-users for improved privacy and reduced latency. The dispersion leverages diversity of compute-network capacities and energy prices, while promotes the coexistence of multiple providers. This drives variation in operational cost, coupled with limited information sharing across providers. Consequently, there is a critical need for an orchestration solution that preserves autonomy and optimizes operational cost across domains, while meeting service requirements. This paper proposes a novel service-based fog management and network orchestrator (sbMANO), which utilizes service metadata in enabling multi-provider resource management. The sbMANO is empowered with a novel optimization algorithm for service-based joint request mapping and response routing. The algorithm acts on partial information and preserves the edge for delay-critical services. The performance of the algorithm is evaluated analytically for delay-aware and delay-agnostic variants. The results show that both achieve near-optimal performance in maximizing user satisfaction with minimum operational cost. Furthermore, the delay-aware variant outperforms the agnostic counterpart, with higher user satisfaction and lower operational cost

    Transitioning to Affordable and Clean Energy

    Get PDF
    Transitioning to Affordable and Clean Energy is a collective volume which combines original contributions and review papers that address the question how the transition to clean and affordable energy can be governed. It will cover both general analyses of the governance of transition, including policy instruments, comparative studies of countries or policies, and papers setting out scientifically sound visions of a clean and just energy system. In particular, the following aspects are foregrounded: • Governing the supply and demand side transformation • Geographical and cultural differences and their consequences for the governance of energy transitions • Sustainability and justice related to energy transitions (e.g., approaches for addressing energy poverty) Transitioning to Affordable and Clean Energy is part of MDPI's new Open Access book series Transitioning to Sustainability. With this series, MDPI pursues environmentally and socially relevant research which contributes to efforts toward a sustainable world. Transitioning to Sustainability aims to add to the conversation about regional and global sustainable development according to the 17 SDGs. The book series is intended to reach beyond disciplinary, even academic boundaries

    Dynamics in Logistics

    Get PDF
    This open access book highlights the interdisciplinary aspects of logistics research. Featuring empirical, methodological, and practice-oriented articles, it addresses the modelling, planning, optimization and control of processes. Chiefly focusing on supply chains, logistics networks, production systems, and systems and facilities for material flows, the respective contributions combine research on classical supply chain management, digitalized business processes, production engineering, electrical engineering, computer science and mathematical optimization. To celebrate 25 years of interdisciplinary and collaborative research conducted at the Bremen Research Cluster for Dynamics in Logistics (LogDynamics), in this book hand-picked experts currently or formerly affiliated with the Cluster provide retrospectives, present cutting-edge research, and outline future research directions

    Extractive Industries

    "New initiatives recognize that resource wealth can provide a means, when properly used, for poorer nations to decisively break with poverty by diversifying economies and funding development spending. Extractive Industries: The Management of Resources as a Driver of Sustainable Development explores the challenges and opportunities facing developing countries in using oil, gas, and mining to achieve inclusive change. While resource wealth can yield prosperity it can also, when mismanaged, cause acute social inequality, deep poverty, environmental damage, and political instability. There is a new determination to improve the benefits of extractive industries to their host countries, and to strengthen the sector's governance. Extractive Industries provides a comprehensive contribution to what must be done in this sector to deliver development, protect often fragile environments from damage, enhance the rights of affected communities, and support climate change action. It brings together international experts to offer ideas and recommendations in the main policy areas. With a breadth of collective insight and experience, it argues that more attention must be given to the development role of extractive industries, and looks to the future to explain how action on climate change will profoundly shape the sector's prospects.
