RFID Warehouse Management in the Small and Medium Enterprises based on Manufacturing Industry Kyunglag Kwon, Yeochang Yoon, Jaehwan Ryu, Jongsoo Sohn, Injeong Chung Intelligent Information System Lab, Department of Computer and Information Science, Korea University, Republic of Korea {helpnara, kai83, berserkjan, mis026, chung}@korea.ac.kr Abstract The recent ERP system has been playing a signifi- cant role in most of the large conglomerates as their warehouse management system. However, complex processes of the ERP system, designed mainly for large enterprises, calls for large workforce putting a financial burden on many small and medium indus- tries. In this paper, we have attempted to find ways for the small and medium industries to reduce their workforce. For this purpose, we present and imple- ment "a RFID system closely coupled with the ERP system" which effectively complements the complexi- ty of the existing ERP system with its functions of simultaneous multiple reading, and automation of the procedures by taking advantage of RFID’s merits of untouchability, convenience and data storing ca- pability. As a result, the small and medium industries as well as large enterprises are able to take advantage of RFID system's merits. They can now control their product management easily, monitoring the status of production in real time as they can conduct ware- house management on the ERP system without extra workforce. 1. Introduction The ERP (Enterprise Resource Planning) system of today is playing a remarkable role in most of the large conglomerates as a way of production management especially in warehousing. Since the existing ERP systems have been used and developed mainly for the convenience and interest of the large conglomerates for management of their enormous volume of logistics, many inconveniencies have arisen for this system to directly apply in the small and medium industries. In this regard, the new technology of the RFID sys- tem is designed to overcome demerits of the barcode which demands individual reading of each product. The new technology helps realize more intelligent process such as checking multiple products simulta- neously and storing a certain amount of data in each RFID tag. Because the RFID system uses a radio fre- quency that can read as many tags as possible accurate- ly in a short time, it effectively replaces a human labor in carrying out the warehouse management process more effectively and accurately. By taking advantage of the RFID system, which computerizes the existing procedures small and medium industries are able to cut workload and thus overcoming difficulties caused by the complexity of the ERP system. In addition, the RFID system could prevent from such wastes as over- production, the excessive inventory of the company's warehouses and additional work processing [1]. In this paper, we present and implement "a RFID system closely connected with the ERP system." By taking advantage of RFID system's merits including untouchability, convenience and capacity to store data [2], it is possible to control products more efficiently than the existing ERP system. By deleting complicated process of the bar code utilizing RFID system, it can both be applicable to the small and medium industries as well as big conglomerates. 2. Backgrounds 2.1.

Because the traditional barcodes have limitations for wireless
