This paper presents the simulation environment of an RFID enterprise network based on EPCglobal architecture framework. The RFID enterprise network consists of tag/reader simulator, reader management server, identification server, EPC global Network, and application system. We implement two important application simulations of supply chain management: container yard management and warehouse management. Application scenarios are described in a scenario player using action scripts; application clients interact with reader simulator through an event server which also monitors operations of the Application Level Events (ALE) middleware and the EPCIS event repository. Tag data are transmitted to the ALE reader control module and filtered and aggregated by ALE data process module according to the ALE ECSpec, and then reports are generated and submitted to capture applications. Upon receiving ALE reports, capture applications will create relative EPC events that are stored in the EPC Information Service (EPCIS) event repository. User interface of operating the tag/reader simulator, ALE middleware, EPCIS event repository, and application scenarios will be demonstrated.
