A RFID-based location tracking scheme for inbound operations in warehouse environment

Enterprises are experiencing a strategic evolution toward the globalization of product market in which customers request better quality of product and faster response time. Thus, good resource management for fulfilling customerspsila requests is one of the key elements for enterprises to survive in this competitive market. Numerous researchers proposed different approaches for handling information and material flows within a supply chain network. Application of emerging technologies, such as Global Positioning Systems, cell of origin architecture, infrared, ultrasonic and active radio frequency identification, for locating and managing resources is one of the approaches. However, the existing technologies are either low accuracy of locating objects or high cost of implementation. It may result in diminishing the competitive power against the competitors. As a result, it is crucial to develop a cost effective scheme to integrate the resource and information flow in the supply chain network in which the visibility can be improved in order to help in the making of real-time decisions. Therefore, an efficient localization scheme for resource management (ELS) is proposed. With the help of passive RFID technology, the warehouse resources can be easily located. Management is able to obtain a real-time and accurate update of the resources status anywhere at anytime.
