Data-Driven Decision Support & Revenue Management

The need for automated decision-making is steadily increasing. The goal is to derive methods and data-driven models for automated decision support for practical applications in uncertain and changing environments. Solving problems in practical applications requires bringing together data management, analytics, optimization, and computer science.

Our research group Data-Driven Decision Support focuses on automated decision-making in the areas of Operations Management and beyond using quantitative methods of operations research (cf. modelling, simulation, and optimization) and data science (cf. AI/ML). Our research has been published in over 80 peer-reviewed publications including renowned Journals (EJOR, JEDC, IJPE, IJPR, COR, DGAA, ITOR, JRPM, JIMS, JCLP, BISE), distinguished data science conferences (ICML, KDD, IJCAI, RECSYS, SDM, ICDM, PMLR, ECML, ICDE), and leading computer science venues (VLDB, EDBT, DAPD, CIKM, EDOC, SSDBM). Rainer serves as a reviewer for over 70 Journals in the areas of operations management, AI/ML, and information systems.

Keywords: Data-Driven Decision Support, Business Analytics, Risk & Robustness, Markov Decision Processes, Reinforcement Learning, Revenue Management & Pricing, Inventory Management, Resource Allocation, Recommerce, Sustainability, Circular Economy

      Artificial Intelligence and Sustainability

      Our research group investigates both the use of energy in developing artificial intelligence (AI) as well as the use of AI in generating, storing and managing energy. This includes research into energy-efficient algorithms for solving basic AI tasks such as classification, ranking or planning & search, as well as the development and application of AI methods to refined modeling of batteries in order to extend their working lifetime, and the control of domestic energy consumption.
