  Abstract
  Radio frequency identification (RFID) technology has been widely used in various fields. In the application system based on RFID technology, mass real-time data is generated by RFID readers. How to deal with and make use of the mass data to serve for enterprises is a great challenge we are facing, and RFID event processing technology can help us solve the problem. In this paper, we will do an in-depth investigation on RFID event processing technology and test its performance in the application of SCM (Supply Chain Management). Firstly, according to the semantic level of RFID events, RFID event can be classified to two categories, that is, RFID simple event and RFID complex event. Secondly, different solutions are adopted in the course of processing of different events. To the RFID simple event, an improved RETE algorithm will be proposed; to the complex event, a novel Petri Net approach will be adopted. Finally, the experiment is carried out in the scene of Beer Game, which demonstrates that RFID event processing technology can mitigate the effects of the Bullwhip in supply chain.
