Article
The rapidly developing concept of carsharing is an essential and scalable part of sustainable, multimodal mobility in urban environments. There is a clear need for carsharing operators to understand their users and how they use different transportation modes to intensify the development of carsharing and its positive impacts on the environment and...
Article
Carsharing is an essential part of the transformation towards sustainable mobility in smaller urban areas. To expand their services and the positive social and environmental benefits, carsharing operators must understand their users' travel behavior. To accelerate this understanding, we analyze usage data of a station-based carsharing service from...

Um die Ziele des Pariser Klimaabkommens zu erreichen, besteht rascher Handlungsbedarf in allen Sektoren. Dies gilt insbesondere für den Verkehrssektor, für den eine umfassende Transformation unumgänglich ist. Aktuelle Forschungsarbeiten zeigen, dass neben der Elektrifizierung des motorisierten Individualverkehrs insbesondere der Ausbau und die Umse...
Article
Due to the rapid growth of the tourism industry, associated effects like overcrowding, overtourism, and increasing greenhouse gas emissions lead to unsustainable development. A prerequisite for avoiding those adverse effects is the prediction of occupancy. The present study elaborates on the applicability and performance of various prediction model...

Conference Paper
The expansion of large-scale charging infrastructure is crucial to cope with growing shares of electric vehicles. However, operators often struggle with profitable operation due to volatile occupancy and high costs for peaks in charging demand. Using information and communication technology may enable smart charging and thereby profitable operation...
Article
Public fast charging infrastructure (FCI) is essential for the adoption of electric vehicles (EVs). To reach higher EV penetration, investments into the development of a comprehensive and widespread fast charging network are necessary. However, current investments in FCI are only profitable in specific locations resulting in a severe lack of deploy...
Preprint
Full-text available
The enormous power consumption of Bitcoin has led to undifferentiated discussions in science and practice about the sustainability of blockchain and distributed ledger technology in general. However, blockchain technology is far from homogeneous - not only with regard to its applications, which now go far beyond cryptocurrencies and have reached bu...
Conference Paper
Full-text available
The widespread adoption of electric vehicles makes investments in charging parks both immediate and necessary to lower range anxiety and allow longer trips. However, many charging park operators struggle with sustainable and profitable operation due to high fees on peak loads and volatile availability of renewable energy. Smart charging strategies...
Article
Full-text available
When talking about blockchain technology in academia, business, and society, frequently generalizations are still heared about its – supposedly inherent – enormous energy consumption. This perception inevitably raises concerns about the further adoption of blockchain technology, a fact that inhibits rapid uptake of what is widely considered to be a...
Article
Full-text available
Sector coupling (SC) describes the concept of a purposeful connection and interaction of energy sectors to increase the flexibility of supply, demand, and storing. While SC is linked to research on smart energy system and locates itself in the research stream of 100% renewable energy systems, it currently focusses on counteracting challenges of tem...

Zusammenfassung Der enorme Stromverbrauch von Bitcoin hat dazu geführt, dass in Wissenschaft und Praxis oft eher undifferenziert Diskussionen über die Nachhaltigkeit von Blockchain- bzw. Distributed-Ledger-Technologie allgemein geführt werden. Allerdings ist die Blockchain-Technologie bereits heute alles andere als homogen – nicht nur hinsichtlich...
Article
Full-text available
Traditional ways of managing information technology (IT) service providers are no longer applicable as companies use more and more services provi-sioned in the cloud. Therefore, organizations are looking for new ways to manage their relationship with cloud providers. The shift from IT-as-a-product to IT-as-a-service puts clients in a continued depe...
Article
Full-text available
The rapid standardization and specialization of cloud computing services have led to the development of cloud spot markets on which cloud service providers and customers can trade in near real-time. Frequent changes in demand and supply give rise to spot prices that vary throughout the day. Cloud customers often have temporal flexibility to execute...
Conference Paper

Artificial intelligence currently counts among the most prominent digital technologies and promises to generate significant business value in the future. Despite a growing body of knowledge, research could further benefit from incorporating technological features, human actors, and organizational goals into the examination of artificial intelligenc...
Article
Full-text available
The growing share of renewable energy generation based on fluctuating wind 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...
Article
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...
Article
Full-text available
Industrial demand response uses a multitude of energy flexibility measures. Their planning and control requires various production IT systems. A widely accepted approach to classify these inhouse IT systems are the levels of the automation pyramid in companies. This paper broadens the scope of this concept to overcome the limitation to companies’ (...
Conference Paper
Information technology units within organizations pursue organizational reliability and agility goals. Both capabilities are imperatives for business success but there is an organizational tension arising in being agile and reliable at the same time. Reliability ensures the stability and business continuity of organizations, whereas agility helps t...

Article
Full-text available
The change of electricity supply from conventional to renewable energy sources is a challenge for the whole society. This transition causes an increase of volatility in electricity supply and therefore threatens both, grid stability and, also, electricity price stability. Besides cost-intensive countermeasures such as grid expansions and power-to-X...

Situation faced: Recent developments in the medical and industrial laboratory market have increased the need for highly flexible laboratory processes. This pressure results from new requirements that have accompanied the internationalization of laboratories and the digitalization of paper-based, bureaucratic work practices. The execution of laborat...
Article
Demand-side flexibility (DSF) in the electricity grid has become an active research area in recent years. While temporal flexibility (e.g. load shedding, load shifting) is already discussed intensively in literature, spatial load migration still is an under-researched type of DSF. Spatial load migration allows us to instantly migrate power-consumin...
Article
Full-text available
Based on the goal of exiting nuclear and fossil energies within the electricity generation, the percentage of renewable energies in the energy mix rises. Due to renewable energies’ dependence on natural resources like sun or wind this development leads to a volatile energy supply on the markets. To satisfy their customers’ needs even with a volatil...

Article
We will examine price dependencies between primary products and co-products from metal markets. First, we develop an optimization model to determine the profit-maximizing extraction behavior of mining companies. With this model, we analyze how the companies optimally react to exogenous demand shocks on the metal markets, and how the prices of metal...
Article
The rising adoption of cloud computing and increasing interconnections among its actors lead to the emergence of network-like structures and new associated risks. A major obstacle for addressing these risks is the lack of transparency concerning the underlying network structure and the dissemination of risks therein. Existing research does not cons...
