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.

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.

Complying with the EU General Data Protection Regulation (GDPR) poses significant challenges for blockchain projects, including establishing clear responsibilities for compliance, securing lawful bases for processing personal data, and observing rights to rectification and erasure. We describe how Germany’s Federal Office for Migration and Refugees addressed these challenges and created a GDPR-compliant blockchain solution for cross-organizational workflow coordination. Based on the lessons learned, we provide three recommendations for ensuring blockchain solutions are GDPR-compliant. [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 ▲]

Initial conditions for the marketing of demand flexibility: status quo analysis and meta study. 2 version

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.

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 ▲]

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.

Bringing Blockchain technology and business process management together, we follow the Design Science Research approach and design, implement, and evaluate a Blockchain prototype for cross-organizational workflow management together with a German bank. For the use case of a documentary letter of credit we describe the status quo of the process, identify areas of improvement, implement a Blockchain solution, and compare both workflows. The prototype illustrates that the process, as of today paper-based and with high manual effort, can be significantly improved. Our research reveals that a tamper-proof process history for improved auditability, automation of manual process steps and the decentralized nature of the system can be major advantages of a Blockchain solution for cross-organizational workflow management. Further, our research provides insights how Blockchain technology can be used for business process management in general. [less ▲]

Blockchain is rapidly evolving and there is an increasing interest in the technology in both prac-tice and academia. Recently, a blockchain use case called Initial Coin Offering (ICO) draws a lot of attention. ICO is a novel form of crowdfunding that utilizes blockchain tokens to allow for tru-ly peer-to-peer investments. Although, more than 4.5 billion USD have been invested via ICOs, the phenomenon is poorly understood. Scientific research lacks a structured classification of ICOs to provide further insights into their characteristics. We bridge this gap by developing a taxonomy based on real-world ICO cases, related literature, and expert interviews. Further, we derive and discuss prevailing ICO archetypes. Our findings contribute to theory development in the field of ICOs by enriching the descriptive knowledge, identifying design options, deriving ICO archetypes, and laying the foundation for further research. Additionally, our research pro-vides several benefits for practitioners. Our proposed taxonomy illustrates that there is no one-size-fits-all model of ICOs and might support the decision-making process of start-ups, investors and regulators. The proposed ICO archetypes indicate how common ICOs are designed and thus might serves as best practices. Finally, our analysis indicates that ICOs represent a valid alter-native to traditional crowdfunding approaches. [less ▲]

To date, research on smart cities has primarily focused on urban congested areas. As this paper points out, it is becoming ever more important to look at intermediate and thinly populated regions like towns and rural areas as arenas for digital innovation. By following a multi-phase research process, we examine towns’ highly individual needs in an exploratory way, derive key aspects from recent literature that can serve to mitigate or solve their problems, and present an open innovation process by way of integrating local context factors, local stakeholders, and suitable information and communication technology solutions. Our objective is to develop a first digital innovation approach in a field that has so far been scarcely considered. We conduct a case study which demonstrates the applicability and effectiveness of our innovation approach in a small town in southern Germany and derive first important lessons learned. Thereby, the concept of an innovation ecosystem reveals a promising solution to face the challenges of the investigated town. [less ▲]
