RTLS(Real Time Location System) is the system to provide information and real-time location of tagged objects by using RTLS tag. In this paper, in order to enhance the performance of the port operation system, and efficient operation method of yard is suggested by applying RFID(Radio Frequency Identification)-based RTLS that provides real-time accurate positions of containers. In the group-based loading sequence system, the containers in the same group should have the similar characteristics such as POD(Port of Destination), size, weight, etc. In order to run this system, we propose the scheme using the parameters to the unspecified N bytes of RFID tag specified in ISO 18000-7. According to simulation result, the group-based system reduces the re-handling ratio of TC(Transfer Crane) in yard. It will reduce the whole lead-time in the process of port pogistics.
