  From LEGO to the Shopfloor: Driving Digitalization Through Process Technology

Processes constitute the major vehicle to support companies to move towards digital business (models). One major application area is smart manufacturing, also referred to as Industrie 4.0. Here, processes connect and integrate machines, actors, sensors, information systems, and business partners, collecting, processing, and exchanging production-relevant data. This yields manifold benefits such as optimized processing and integrated data analysis. Designing and implementing such solutions touches and raises many research challenges, including the flexible and robust implementation of distributed process networks and the application and extension of process-oriented data analysis methods. We illustrate these challenges by our own journey from a LEGO-based Industrie 4.0 lab setting to the centurio.work manufacturing orchestration suite.

Data Science Panel: Database systems in the age of AI and Data Science

Time: 15:30-16:45
Location: Physics HS1
Moderation: Volker Markl (TU Berlin)
Participants:

• Erhard Rahm (University of Leipzig)
• Bernhard Mitschang (University of Stuttgart)
• Thomas Seidl (LMU München)
• Wolfgang Lehner (TU Dresden)

Artificial intelligence (AI) is currently the buzzword on everyone's lips. Companies are investing heavily in AI research; the German government has also adopted an AI strategy. What is hype, what is real? What role do database systems play in AI and data science? Which technological challenges need to be solved? How does database research contribute to national centers of excellence in big data and machine learning? AI requires data - how does the research of the community to solve the problems in AI applications? Which research results already exist? Which topics offer new research and innovation potential? These and other questions about effects of trend and hype issue of "AI" on education, research and innovation will discuss the panel.
