Multifacility location with imprecise data

Ankara : The Department of Industrial Engineering and the Institute of Engineering and Science, Bilkent Univ., 1994.Thesis (Master's) -- Bilkent University, 1994.Includes bibliographical references leaves 75-78.Locational decisions often suffer from lack of precise data. In this study, we consider a class of multifacility location problems where the demands of existing and new facilities are unknown, with a known set of possible realizations. The set may be finite or infinite. In the latter case, the data is assumed to be of interval type. We use various criteria to evaluate candidate solutions to these problems and build a framework for decision making.Demir, Muhittin HakanM.S

FAIR Metadata Standards for Low Carbon Energy Research—A Review of Practices and How to Advance

The principles of Findability, Accessibility, Interoperability, and Reusability (FAIR) have been put forward to guide optimal sharing of data. The potential for industrial and social innovation is vast. Domain-specific metadata standards are crucial in this context, but are widely missing in the energy sector. This report provides a collaborative response from the low carbon energy research community for addressing the necessity of advancing FAIR metadata standards. We review and test existing metadata practices in the domain based on a series of community workshops. We reflect the perspectives of energy data stakeholders. The outcome is reported in terms of challenges and elicits recommendations for advancing FAIR metadata standards in the energy domain across a broad spectrum of stakeholders

Understanding the Citizen’s Role in the Transition to a Smart Energy System: Are We Ready?

Energy transition is one of the main pillars of the European Union’s climate change strategy suite. The policies set forth by European Union members to support energy transition are transposed into national policies, strategies, and action plans. Energy transition calls for empowering citizens and communities regarding energy-related initiatives. Of particular importance are smart energy systems and their potential for involving individuals and communities in energy transition initiatives. However, not all citizens are willing to invest in renewable energy or smart appliances. Thus, there is a need for implementing smart energy initiatives, which have three main steps, namely, awareness, mindset (readiness for action), and action. Bearing in mind the lack of uniformity in this area across the European Union, this manuscript assesses the levels of awareness, mindset, and action utilizing the results of a comprehensive international survey, the ECHOES project, with respect to demographic and socioeconomic variables, such as age, income level, and education level. The analysis reveals that 58% of respondents from the West European sample demonstrate a high level of awareness, 56% are ready for action, and 63% already demonstrate action. The percentages are similar for the East European sample, with 56% demonstrating a high level of awareness, 55% are ready for action, and 66% already demonstrating action. Overall, women have higher levels of awareness, readiness for action, and action. For both Western and Eastern European countries, education level and income level are important factors for smart energy adoption, with education levels proving to be more significant for East European countries

Establishing an energy security framework for a fast-growing economy: Industry perspectives from Turkey

Energy security is currently one of the priorities in governmental agendas, particularly for fast-growing economies such as Turkey. These economies which typically depend on energy-intense industrial production require a consistent, reliable supply of energy to support their economic development, especially the ones with limited indigenous energy resources. As the Industrial sector plays a major role in energy demand, the successful implementation of energy security strategy also depends on the cooperation of intensive energy consuming industrial companies. Therefore, this paper investigates the interrelationship between Turkish industry's perspective and government's energy security strategy papers, providing a case with the potential to enlighten the process. It also aims to gain insight into the industry sector's view of the energy security in this context, through a qualitative inquiry. An analysis of resulting concepts, and the interaction and interrelation among these enable the development of a Turkish energy security framework based on the views of industrial sector. In addition, a set of policy recommendations are developed following this framework. This study also identifies possible areas of discrepancies between industry and government perceptions, and thus, potentially promoting levels of interaction and understanding between the two key parties.

The Significance of Enabling Human Consideration in Policymaking: How to Get the E-Ferry That You Want

There is broad agreement in literature and policy that the transport sector needs to maximise electric mobility, in order to lower both energy consumption and greenhouse gas emissions. This ongoing transformation continues to require a high degree of technological innovation. Consequently, policymakers are striving to reward innovation in procurement tender contracts, in order to achieve sustainable innovation. At the same time, such contracts are often designed with a principle of technology neutrality in mind, to prevent any distortion of the market logic. This article suggests that it is misguided to try to perfect the logic of the tender system and that articulating contract that rewards innovation is no guarantee of a sustainable solution. Rather than being technological, the problem should be seen as moral: the mounting environmental challenge. Policymakers thus have clear ideas about the action needed based on what they, through moral conviction, consider to be appropriate action. This case study—conducted as a part of the EU H2020-funded ECHOES Project under Work Package 6—on the electrification of the Flakk–Rørvik ferry connexion reveals how policymakers were able to achieve the intended results: in this case, an e-ferry rather than a biodiesel ferry, in spite of, rather than because of, the tender system logic. They achieved this by involving stakeholders in the process with a continuous and uninterrupted dialogue. The project stakeholders were able to intervene in the tender system logic in favour of human considerations. We argue that this project was a success because human judgement, not system logic, was the driving force. By extension, we argue that systems will only allow policymakers to pursue moral issues to the degree that they allow human intervention.publishedVersio

Assessing Türkiye’s Prospective Involvement in the Arctic Region: A Qualitative Inquiry from Energy and Environmental Perspectives

Recent developments in the Arctic region, mainly marked by climate change, have caused the region to receive increasing attention from regional and non-regional actors, mainly due to emerging energy-related opportunities and environmental concerns. The main reason for non-regional stakeholders to become involved in the Arctic region to pursue their interests is to obtain the observer status in the Arctic Council. Accordingly, this manuscript analyzes the long-term perspective of Türkiye’s involvement in the Arctic region as a non-regional actor and reveals a set of enablers and disablers pertaining to energy and environmental domains. For this purpose, in-depth interviews with experts from Türkiye, with Arctic Council members, or with observer countries are conducted. Results of the analysis are also utilized to provide insights regarding countries with similar profiles to Türkiye, i.e., middle-power and developing countries that are geographically distant from the Arctic region. The results highlight energy security, hydrocarbon reserves, and climate change as significant factors for countries such as Türkiye. Scientific, private sector, or intergovernmental cooperation with regional actors to encourage global action and environmental initiatives are the main enablers. Challenges in the extraction and sharing of energy resources, high costs and high technology requirements of energy exploration and extraction activities, increasing human activity, and damages to the Arctic ecosystem are identified as significant disablers

Examining the barriers and motivators affecting European decision-makers in the development of smart and green energy technologies

The nature of the utility market is changing. Developing smart and green technologies are essential to overcoming the challenges in the decades to come. Moreover, smart and green technologies are vital to reducing carbon emissions, achieving future goals of sustainability, and assuring electric stability to cities and their citizens. Hence, development of these energy-related technologies have become an important priority across Europe. To this end, this study examines the literature on interactions between several social actors regarding the advancement of smart and green energy technologies. The analysis is based on the identification of three levels of formal social decision-making units, namely, Formal Social Units, Collective Decision-Making Units, and Individual Consumers engaging in joint contracts. The attitude dimensions, motivators and barriers concerning the energy behaviors of the three decision-making units are identified through a comprehensive literature review. Similarities and differences in decision-making processes related to each level and the reasons for delays in achieving targets are identified. Moreover, a policy framework for involved stakeholders of smart and green energy technologies is presented
