The goal of the DEBS Grand Challenge series is to contribute to the Event Processing Grand Challenge, that serves as a common goal and mechanism for coordinating research focusing on event processing. DEBS Grand Challenge series provides a common ground and evaluation criteria for a competition aimed at both research and industrial event-based systems. The goal of the DEBS Grand Challenge participants is to implement a solution to a specific problem provided by the DEBS Grand Challenge organizers. In this paper we present a description of the DEBS 2012 Grand Challenge problem focusing on the high-tech manufacturing domain. Moreover we provide a set of both: (1) real-life data and (2) queries which can be used by the DEBS 2012 Grand Challenge participants as well as research community at large.
