Architecture, implementation and application of complex event processing in enterprise information systems based on RFID

Abstract

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, 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 is put forth, and the rules are defined. 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.

Leveraging complex event processing for smart hospitals using RFID

“…A rule is the predefined inference logic or pattern for detecting complex events. Several studies (Zang et al, 2008;Wang et al, 2009) have described different syntax for CEP rules. We use ECA (event-condition-action)-like rule expression language to describe event patterns since it is easier to use and more understandable.…”

“…Son et al (2007) proposed an efficient method to create business-level events using CEP based on RFID standards. Other works have provided solutions and developed systems to integrate non-RFID data to detect complex events (Bornhövd et al, 2004;Zang et al, 2008).…”

Rule Modeling Engine for Optimizing Complex Event Processing Patterns

“…NFA have applied NFA by earlier researchers for modeling as a tool [6,7,15,19], pattern matching [18,20], and fuzzification [16,17]. On the other hand CEP developers have used it in modeling [21,23,24] and pattern matching [6,7,22,25]. Indeed A-priori algorithm was employed in rule mining [26,27,28,29,30,31,32] and modeling [33,34,35,36].…”
