This paper presents a novel Complex Event Mining Network (CEMN) and defines the fundamentals of radio-frequency identification (RFID)-enabled supply chain event management and discusses how an Complex Event Processing (CEP) can be used to resolve the underlying architecture challenges and complexities of integrating real-time decision support into the supply chain. The proposed CEP architecture is a distributed Event Processing Networks (EPNs) capable middleware infrastructure which enables automatic and real-time routing, caching, filtering, aggregation and processing of RFID events. It provides a global platform for distributed execution and management of RFID-enabled supply chain data. It enables a federated control over supply chain nodes deployed in many different organizations, respecting diverse security requirements while supporting centralized deployment and management of processes and rules. Finally, a distributed complex event detection algorithm based on Master-workers pattern is proposed to detect complex events and trigger correlation actions. The results showed that our proposed approach has more robust and scaleable in large-scale RFID applications.
