To improve RFID application reliability in complex manufacturing environment, a set of evaluation indexes for evaluating RFID application reliability were suggested, and a layered data processing model was presented to improve RFID application reliability. The model consisted of two layers, the primitive event processing layer and the complex event processing layer. The former received primitive reading events from the reader-network, cleaned duplicated events by duplication elimination constraint. Thus tidy and exclusive logic reading events were obtained. Then based on establishing application integrity constraints and analyzing logic reading events, the complex event processing layer detected and corrected false positive readings and false negative readings. Taking physical object’s route constraint as an example, the identifying method of false positive readings and false negative readings were described. The results of application show the availability of the model.
