CHAIR IN INFORMATION AND SERVICE SYSTEMS (ISS)

Chair in Business Administration, especially Information and Service Systems at Saarland University deals with the development and management of data-driven services, for instance healthcare. Directed by Prof. Dr.-Ing. Wolfgang Maaß, the chair investigates how the application of experimental design methods combined with distributed, data analytic approaches lead to adaptive service designs and innovative solutions. This research is conducted in basic and applied research projects in cooperation with leading research and industry partners. Results are applied and validated in industry projects by the research group Smart Service Engineering (SSE) at the German Research Center for Artificial Intelligence (DFKI).

Call for Papers – Quantum Computing Applications – HICSS 2024 – Hawaii International Conference on System Sciences

Quantum computing is a rapidly evolving field with a wide range of applications in diverse industries. Hybrid quantum computing combines classical and quantum computing to solve complex problems, quantum machine learning is a subset of machine learning that leverages quantum computing for optimization, and quantum embeddings use quantum algorithms to process high dimensional data. Quantum computers have the potential to revolutionize finance, industry, production, drug research, and even consumer-facing services. With quantum computing’s ability to handle massive amounts of data and perform complex calculations at incredible speeds, it holds great promise for addressing some of the world’s most pressing problems in these areas. The minitrack invites researchers from computer science, natural sciences, engineering, and economics fields to submit their research on applications of quantum computing.
