초록

최근 RFID 기술과 기업정보시스템을 연계하여 사용하려는 많은 시도가 진행되어 왔다. 하지만, 대부분의 경우 동시에 많은 양의 인식할 수 있는 RFID의 기본적인 특징에만 충실했을 뿐, 리더로부터 생성되는 많은 양의 데이터에 대한 관리적인 측면을 고려하지 못하고 있다. 그 결과, 이러한 시스템을 통해 시간이나 흐름과 관련된 연속적이고 동적인 정보를 얻기가 어렵다. 본 논문에서는 대량의 RFID 데이터를 효율적으로 관리하기 위해 RFID 데이터 마이닝 기법의 하나인 경로 트리(PathTree)를 보완한 공정트리(Procedure Tree)라는 새로운 방법을 제안한다. 제안한 방법을 실제 기업 정보 시스템과 연계하여 실시간 공정 관리 시스템에 적용한 후 제안한 시스템의 효율성을 평가한다. 제안한 방법을 통해 기존 RFID 기반 생산관리 시스템이 하기 어려운 실시간 공정 관리를 위한 공정 흐름의 예측이나 추적과 같은 업무를 효과적으로 수행할 수 있었다.

In recent years, there have been many attempts to connect the latest RFID (Radio Frequency Identification) technology with EIS (Enterprise Information System) and utilize them. However, in most cases the focus is only on the simultaneous multiple reading capability of the RFID technology neglecting the management of massive data created from the reader. As a result, it is difficult to obtain time-related information such as flow prediction and analysis in process control. In this paper, we suggest a new method called 'procedure tree', an enhanced and complementary version of PathTree which is one of RFID data mining techniques, to manage massive RFID data sets effectively and to perform a real-time process control efficiently. We will evaluate efficiency of the proposed system after applying real-time process management system connected with the RFID-based EIS. Through the suggested method, we are able to perform such tasks as prediction or tracking of process flow for real-time process control and inventory management efficiently which the existing RFID-based production system could not have done.
