Abstract

This paper presents the development of a stock control system of POP system design based on RFID in SCM and its economic efficiency. A stock control system is proposed for 900MHz passive type RFID system. The RFID system is composed of a RFID reader and four antennas to read the tag IDs. A cost estimation model is adapted based on the total product profit by various tag prices. The result of the economic efficiency analysis can indicate any invested model for the automation system which have initial investment should be used. This solution indicates the limit of the break even point according to the input. And it can be concluded that the stock control can be developed by RFID readers and passive tags with directional arrangement of several antennas. Also, the economical evaluation model can be a decision method for company to adapt the new developed system.

본 논문의 목적은 재고관리를 위한 RFID 시스템을 도입하는데 있어서 적합한 비용을 산출하여 경제성을 평가하고, SCM 환경에서 생산시점 재고관리 모형을 설계하는 것이다. 경제성 분석은 변화하는 태그의 가격에 따른 총 생산 순이익을 기준으로 하였으며, 초기투자가 필요한 시스템에 적용될 수 있게 결정 모델을 설정하였다. 재고관리 시스템은 900MHz 대역의 수동형 태그를 사용하는 RFID 리더와 4개의 안테나를 이용하여 구현하였다. 그 결과 태그가격의 한계치 설정에 따른 구현 시스템의 도입을 결정하는 도구를 개발하였으며, 안테나의 방향성 있는 배치에 의해서 성공적인 재고관리 시스템을 설계하였다.
