the current store inventory as well as the information regarding the trend of demand through the Electronic Data Interchange (EDI) capabilities [6]. The daily advancements in information technology has led to business partners adopting the Internet and Web technology in their supply chain. The Internet has led to a net work flow of information and with integration of the Web, this has lead to a variety of business partners in the supply chain participating in the supply chain processes. The Internet is a fast transmission of information over a net work which leads to a seamless real time communication between business partners. Information on the Internet can be exchanged through Web pages. A variety of products and services can be accessed on the Web sites of suppliers. Web technology provides real time flow of data between the different links of the supply chain leading to collaboration among business partners [7]. 2.2 Current methodologies 2.2.1 Electronic Data Interchange(EDI) EDI, a data format used for inter-business messaging was partially responsible for reducing costs and increasing productivity in the manufacturing and service industries. EDI’s intended purpose was to provide a common messaging standard for businesses to communicate with other businesses. Rather than having to deal with a different data format for each trading partner, all businesses could convert their proprietary data format to EDI to send or receive messages and then convert EDI to their respective proprietary formats. Over the years, EDI has evolved into a mechanism for integrating back office systems and communication with business partners that has served its users well. However, it has inflexible, inherent, and practical problems that put a ceiling on its usefulness. EDI was an unlikely choice for a use other than inter-business messaging [23]. EDI’s Problems Integration of EDI with an organization’s internal computer systems and with those of trading partners was considerably a difficult task. This was mainly due to the incompatibilities between EDI software and in-house applications, and the existence of several standards for information exchange of protocols, procedures, and data forms. There were also system 6
stability issues such as disaster recovery, data backup and error recovery which were major concerns of most business organisations[17]. Security issues such as the disclosure of messages, modification of message contents, modification of message sequence, sender masquerade and repudiation of message origin or receipt were a serious concern for EDI users. The failure to detect such security risks could damage the communication and partnerships between trading partners [17]. 2.2.2 Radio Frequency Identification(RFID) RFID is a method of identifying items using radio waves and this technology allowed automatic collection of product data quickly and easily without human intervention [22]. It consists of the RFID tag or transponder, which is located on the object to be identified and was the data carrier in the RFID system;the RFID reader or transceiver, which is able to both read data from and write data to a transponder and the back-end database which associates records with data collected by readers [21]. The tag is made up of a microchip with a coiled antenna and a reader with an antenna which sends out electromagnetic waves that form a magnetic field when they couple with the antenna on the tag. The tag obtains power from the magnetic field which it uses to power the microchip circuits. The waves that the tag sends back to the reader are modulated by the chip and the reader converts the new waves into digital data [22]. Problems with RFID Since RFID systems make use of the electromagnetic spectrum, they are relatively easy to jam using energy at the right frequency. This provides an inconvenience for consumers in stores in form of longer waits at the checkout. Also, active RFID tags that use a battery to increase the range of the system can be repeatedly interrogated to wear the battery down, disrupting the system. It should also be noted that radio waves cannot be read through metal. Simply wrapping several layers of aluminum foil around an item can defeat the security system in super stores [19]. One of the primary issues to be concerned with a RFID implementation is the immaturity of the industry. Standards are only just being developed. Tags and readers are being modified and improved at a rapid rate. Competing technologies and non-crosscomplient systems 7
