Enterprises have to be increasingly agile and responsive to address the challenges posed by the fast moving market. With the software architecture evolving into service-oriented architecture (SOA), and the adoption of radio frequency identification (RFID), event processing can fit well in enterprise information systems in terms of facilitation of event aggregation into high level actionable information, and event response to improve the responsiveness. To make it more applicable, the architecture of event processing in enterprise information systems is proposed; event meta model and context serve as the solid basis for event processing; the rules, operators and keys of complex event processing are defined. Especially, workflow model is firstly used to extract complex event pattern. We have implemented the event processing mechanism in enterprise information systems based on RFID, including the architecture, data structures, optimization strategies and algorithm. The performance evaluations show that the method is effective in terms of scalability and the capability of event processing. Complex event processing can improve operational performance and discover more actionable information, which is justified by application. Finally, lessons learned from the application are presented.

To improve the detect efficiency, classification and partition of event instance is utilized. We have implemented the event processing mechanism in enterprise information systems based on RFID, including the data structures, optimization strategies and algorithm that is considered as one of the contributions. The performance evaluations show that the method is effective in terms of scalability and the capability of event processing. Complex event processing can improve operation efficiency and discover more actionable information, which is justified by the application.
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.
