Consumer trends like local consumption, sharing of property, and environmental awareness change our habits and thereby our surroundings. These trends have their origin in our direct environment, in the districts of our city or community, where we live and socialize. Cities and districts are changing to “smart cities” and “smart districts” as a part of the ongoing digitalization. These changes offer the possibility to entrench the idea of sustainability and build a platform-based ecosystem for a sustainable smart district. This research aims to identify guidelines in form of preliminary design principles (PDPs) for sustainable smart districts. To achieve this, we conduct a structured literature review. On this basis, we derive and develop PDPs with the help of semi-structured interviews and a non-representative sample of the German population. The resulting nine PDPs describe a first insight into the design of sustainable smart districts. [less ▲]

Given the increasingly volatile prices on the power markets, it becomes economically more and more important for companies to develop and realize flexible strategies for energy consumption. A steady adaption of production processes which considers current power prices can take place on several levels of the automation pyramid, where each level has its own characteristics and requirements. In this paper, we present an optimization architecture based on an IT-platform which meets the challenges of complex multilayered production processes. We introduce layer-specific optimization strategies as well as an associated information flow, which facilitates creating holistic and well-coordinated optimizations. [less ▲]

Information technology (IT) units within organizations pursue both organizational reliability and agility goals. Reliability ensures the stability and business continuity of organizations, whereas agility helps to detect and exploit market opportunities. In our research, we study projects in 19 organizations and unravel the relationship between agility and reliability. We observe that in certain cases reliability can undermine agility and vice versa. Global rules, routines, and procedures can hinder organizational agility whereas responding creatively for agility can locally undermine global organizational reliability. Further, we find that organizations often use decoupling to deal with this trade-off. Although decoupling enables them to be agile and reliable at the same time, it risks undermining both capabilities in the future, by encouraging the accumulation of technical debt. We find indications of how technical debt limits opportunities to creatively respond and can increase vulnerabilities. [less ▲]

The growing share of renewable energy generation based on fluctuatingwind and solar energy sources is increasingly challenging in terms of power grid stability. Industrial demand-side response presents a promising way to balance energy supply and consumption. For this, energy demand is flexibly adapted based on external incentives. Thus, companies can economically benefit and at the same time contribute to reducing greenhouse gas emissions. However, there are currently some major obstacles that impede industrial companies fromtaking part in the energymarkets. A broad specification analysis systematically dismantles the existing barriers. On this foundation, a new end-to-end ecosystem of an energy synchronization platform is introduced. It consists of a business-individual company-side platform, where suitable services for energy-oriented manufacturing are offered. In addition, one market-side platform is established as a mediating service broker, which connects the companies to, e.g., third party service providers, energy suppliers, aggregators, and energy markets. The ecosystems aim at preventing vendor lock-in and providing a flexible solution, relying on open standards and offering an integrated solution through an end-to-end energy flexibility data model. In this article, the resulting functionalities are discussed and the remaining deficits outlined. [less ▲]

In this article, we present a new descriptive model for industrial flexibility with respect to power consumption. The advancing digitization in the energy sector opens up new possibilities for utilizing and automatizing the marketing of flexibility potentials and therefore facilitates a more advanced energy management. This requires a standardized description and modeling of power-related flexibility. The data model in this work has been developed in close collaboration with several partners from different industries in the context of a major German research project. A suitable set of key figures allows for also describing complex production processes that exhibit interdependencies and storage-like properties. The data model can be applied to other areas as well, e.g., power plants, plug-in electric vehicles, or power-related flexibility of households. [less ▲]

The customer requirements for mobility systems are changing. Travelers increasingly expect a carefree travel experience with any starting or destination point ("Seamless Mobility as a Service") - and that with a single booking and billing for all means of transport used. In order to meet this need, the idea of ​​an open and decentralized mobility system is increasingly being discussed, which can integrate the offers of various mobility providers through a common, neutral system. Before such a system can take a concrete form, however, a clear understanding of the opportunities and risks as well as the specific requirements of end customers and mobility providers on such a system is required. The aim of this study is to identify and evaluate the general opportunities and risks of a corresponding system, as well as the general feasibility of the requirements placed on such a system. A multi-method approach was chosen for this purpose. This makes it possible to examine a holistic picture of the requirements of end customers as well as mobility providers and other stakeholders (e.g. technology providers). Records from a workshop with the (associated) partners in the OMOS project and the results of a literature analysis were used as the basis for data collection. To examine the end customer needs, two surveys were carried out with a total of 352 participants, whose questions were derived from practical workshops (survey I) and theoretical models (survey II). In addition, an interview study was carried out with 15 experts to discuss the requirements of various stakeholders, on the basis of which general topics in the field of seamless mobility were also asked.

Energy from renewable resources is not always readily available. Depending on the season and the weather, the power made available by solar parks or wind turbines varies, for example. Due to the continuous expansion of renewable energies, the volatility in the energy system will become more and more pronounced in the future. Preparing and adapting the industry to the changing supply structures is a major challenge for the next few decades. In the future, companies must be able to design their processes and operational organization in such a way that energy consumption can at least partially adapt flexibly to the volatile energy supply. In addition to developing technologies, Concepts and measures to make industrial processes more energetic, a second focus of future work is the development of a consistent IT infrastructure with which companies and energy providers can provide and exchange information from the production machine to the energy markets in the future. This leads to a paradigm shift in the operation of industrial processes - away from continuous and purely demand-driven energy consumption towards the adaptable, energy-flexible operation of industrial plants. This reference work presents the most important results of the research in the context of the Kopernikus project Synergy and clarifies trend-setting findings for further developments in the still young field of industrial energy flexibility.

The present work is part of the research project "Synchronized and energy-adaptive production technology for the flexible alignment of industrial processes to a fluctuating energy supply (SynErgie)" funded by the Federal Ministry of Education and Research. As one of the "Kopernikus projects for the energy transition", the SynErgie research project aims to enable energy-intensive industries in Germany to adapt their electricity demand to the increasingly fluctuating electricity supply. In the past, electricity systems were usually designed so that the generation side of the market was adapted to the temporal behavior of consumption. However, due to the increased expansion of volatile renewable energies, power generation is subject to uncontrollable, weather-dependent fluctuations, which is why making the overall system more flexible is becoming increasingly important. Because the producer side can only offer the required flexibility in the form of a reduction in feed-in, there is a so-called flexibility gap. As became clear on December 14, 2018 and January 10, 2019, this flexibility gap is already pushing the power system to its limits of stability. Only through the use of many compensation mechanisms or With options for flexibility, the security of supply could just be maintained on these days. The industrial processes considered in SynErgie represent a subset of potential flexibility options and can contribute to load adjustment to fluctuating generation as well as to the provision of system services and relief of the grids. In a liberalized, competitive electricity market, the market and regulatory framework conditions are of great relevance with regard to the development of the potential for flexibility in demand. This study therefore first describes the basics of the electricity market design and the constituent legal framework. Current discussions about the basic price system (unit price system vs. zonal system vs. nodal system) are not dealt with. The processing of these discussions as well as the specific analysis of the effects of the price system on demand flexibility is the content of the work packages of the Cluster IV “Market and Electricity System” pending in SynErgie II. The present study therefore rather works on potential obstacles to the participation of flexible demand processes and always refers to the application to industrial processes. The analysis forms the basis for future work in Cluster IV and provides cross-cluster information about the status quo of market structures and regulatory framework conditions. In addition to the systematic processing of the market framework, the scientific literature and already published studies on the subject of demand flexibility (demand side management and demand response) are analyzed and summarized in a meta study.

The increasing share of renewables confronts existing power grids with a massive challenge, stemming from additional volatility to power grids introduced by renewable energy sources. This increases the demand for balancing mechanisms, which provide balancing power to ensure that power supply always meets with demand. However, the ability to provide cost-efficient and eco-friendly balancing power can vary significantly between locations. Fridgen et al. (2017) introduce an approach based on geographically distributed data centers, aiming at the spatial migration of balancing power demand between distant locations. Although their approach enables the migration of balancing demand to cost-efficient and/or eco-friendly balancing mechanisms, it will come up against limits if deployed on a global scale. In this paper, we extend Fridgen et al. (2017)’s approach by developing a model based on geographically distributed data centers, which not only enables the migration of balancing demand but also compensates for this migration when it is contradictory between different balancing power markets without burdening conventional balancing mechanisms. Using a simulation based on real-world data, we demonstrate the possibility to exploit the potential of compensation balancing demand offered by spatial load migration resulting in economic gains that will incentivize data center operators to apply our model.

IT project portfolios, consisting of IT projects, also interact with the entire IT landscape. In case of a failure of only one element, existing dependencies can lead to a cascade failure, which can cause high losses. Despite the present effects of systemic risk, research into IT portfolio management lacks suitable methods to quantitatively assess systemic risk. We follow the design science research paradigm to develop and evaluate our ‘on track’ or ‘in difficulty’ (TD) method by applying the SI model, representing a recognized network diffusion model in epidemiology, in an IT portfolio context. We evaluate our method using a real-world dataset. We introduce a criticality measure for diffusion models in IT portfolios and compare the TD method’s results and the alpha centrality to human judgment as a benchmark. From our evaluation, we conclude that the TD method outperforms alpha centrality and is a suitable risk measure in IT portfolio management. [less ▲]

Even though globalization has led to larger, faster, and more efficient supply chains, at the same time the new worldwide interconnection has also resulted in major challenges with respect to hidden systemic risks. In particular, there is a lack of a holistic perspective on the entire supply network. This missing global view prohibits the anamnesis and management of underlying risks. Against this backdrop, in this paper we discuss the potential contributions of Blockchain technology to systemic risk management in global supply chains and networks. Given the increasing number of recent initiatives of businesses in the context of Blockchain, we argue that Blockchain technology can lower the hurdle for the use of secure multiparty computation. Ultimately, it may be possible to implement a corresponding monitoring mechanism for systemic risks without (i) the need of a central authority and (ii) revealing competition relevant, confidential information to other supply network participants.

Digital technologies are changing our society in many ways. In addition to significant increases in productivity and new forms of value creation, the rapid digital change also brings with it a multitude of political and social challenges. While the digitization of the public sector in Germany is still facing challenges, other countries are already further. For example, Estonia has already largely digitized its administration. The federal government would also like to advance Germany with a targeted digitization strategy and strengthen public administration through the use of digital technologies. One of the focus technologies in this context is blockchain. Blockchain is a decentralized data structure, in which data in cryptographically linked blocks can be stored invariably and traceably. The essential concept of blockchain technology is to manage the data to be stored through a subscriber network instead of a central instance. In addition, new blockchain technologies make it possible to automate parts of the cross-agency process management. Due to its properties, blockchain technology offers a good opportunity for coordination in federal structures, as required by the German asylum process. In addition to one body primarily responsible, the Federal Office for Migration and Refugees, other authorities at both federal and state level are involved in the asylum process. For example, initial reception centers and immigration authorities are subordinate to the respective federal states or part of the local government. This results in a large number of process variants, heterogeneous IT infrastructures and an incomplete digital exchange of information. A cross-agency data source already exists in the form of the Central Register of Foreigners (AZR). The AZR contains a large amount of data that may be recorded and stored by the authorized authorities in accordance with applicable law (especially AZRG). In addition, there is a need for IT-based support for cross-agency communication and cooperation. The Federal Office for Migration and Refugees has now evaluated to what extent blockchain can contribute to overcoming these challenges and promote the establishment of digital identities in the asylum context as well as cross-agency communication and cooperation. A proof-of-concept project that the Federal Office carried out in the first half of 2018 serves as an essential reference point. The project began with the selection of the use case ("simplified asylum process") and a pre-evaluation of the suitability of the blockchain technology. After a positive pre-evaluation, a suitable system was developed by a mixed team from the Federal Office, the Fraunhofer FIT Business Informatics project group and a technology partner. The project was then evaluated according to a blockchain-specific evaluation framework. In addition to technical and professional aspects, the focus here was in particular on issues relating to data protection law. The proof-of-concept project has shown that the use of blockchain technology could support cross-agency communication and cooperation in the asylum process. In addition, blockchain could lay an important foundation for the establishment of digital identities and make the process flow of an asylum seeker traceable on the basis of such an identity. It is true that it has not yet been possible to fully implement all applicable data protection regulations in the developed proof-of-concept. However, the knowledge gained in the course of the project forms a promising basis for the development of a data protection-compliant blockchain-based solution for the asylum process. In addition, due to the federal structure taken into account, the developed concept could also be scaled beyond Germany's borders. A blockchain-based, transnational management of asylum processes could thus become a joint project of the European member states to strengthen cooperation while preserving federal structures. Blockchain technology could thus be the beginning of digital federalism in Europe (also in the asylum area). [less ▲]

Globalization, and outsourcing are two main factors which are leading to higher complexity of supply chain networks. Due to the strategic importance of having a sustainable network it is necessary to have an enhanced supply chain network risk management. In a supply chain network many firms depend directly or indirectly on a specific supplier. In this regard, unknown risks of network’s structure can endanger the whole supply chain network’s robustness. In spite of the importance of risk identification of supply chain network, firms are not willing to exchange the structural information of their network. Firms are concerned about risking their strategic positioning or established connections in the network. The paper proposes to combine secure multiparty computation cryptography methods with risk identification algorithms from social network analysis to address this challenge. The combination enables structural risk identification of supply chain networks without endangering firms’ competitive advantage. [less ▲]

Digitalization promises unprecedented opportunities for public sector institutions to increase efficiency of current and to introduce new services. One of these opportunities are unique digital identities which could improve migration and refugee management, simplify distribution of social services, and improve healthcare systems. A major challenge, however, to the adoption of such digital identities is finding a suitable technological basis. Blockchain might be such a technology. The challenges of introducing blockchain-based digital identities, however, are both significant and fuzzy. To provide guidance on how to overcome these challenges, we provide a detailed exploration of blockchain-based platformization of digital identities and discuss interview insights from refugee and migration management in Germany. We find that blockchain offers promising solutions for unique digital identity management. Likewise, we find that implementation in the public sector would entail a range of organizational and technological challenges. Successful adoption, on the other hand, might ultimately pave the way for decentral and efficient e-government services. [less ▲]
