Abstract. Expensive production equipment requires continuous monitoring to gather data in real-time, e.g., to detect problems, to assess the quality of produced parts, to collect information about the machine states, and consequently to optimize production processes. However, the increasing amount of data -from sensors or systems -and its continuous processing are a big challenge for an IT infrastructure. This paper presents a hybrid system, consisting of a distributed CEP (complex event processing) system to process data in real-time augmented with an in-memory database to extend the available memory as well as the processing capabilities of the overall system. Besides the description of the system architecture, details about the implementation of the concepts in a real production environment are given.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
