We present a case study of an RFID project at Galeria Kaufhof, a subsidiary of Metro Group and one of the largest department store chains in Europe. The trial shows that operational efficiency gains through the automation of logistical in-store processes, such as inventory counting or goods receipt, are possible. Moreover, RFID enables new customer applications on the sales floor, which allow for a redesign of the customer interface, and thus an improvement of the service processes and the service quality. In addition, the analyses of the gathered data on the sales floor help to close the “data void” between the goods receipt and the point of sales of the department store, thus offering the opportunity to directly observe and analyze physical in-store processes. The RFID data analyses allow for deriving valuable information for the department store management in the areas of inventory management, category management, store layout management , and department store processes .

To get there, however, a critical piece is yet missing: a Discovery Service to identify possibly unknown supply chain actors holding relevant data for specific EPC numbers of individual products. Unfortunately, the Discovery Service architecture as initially conceived by EPCglobal needs revision as it either infringes the confidentiality of participating companies or its use is limited to identifying only participants already known. Against this background, this paper first discuusses the limitations of the architecture under consideration by EPCglobal and presents an alternative, more adequate Discovery Service design. Our concept encourages participation in the network while ensuring information provider confidentiality. Secondly, we present a roadmap for extending the existing EPCglobal Network with two critical services: an automated contract negotiation service and a billing service.

Dieser Beitrag vergleicht im Rahmen einer Simulationsstudie den herkömmlichen Prozess der Nachbefüllung mit manueller Bestandskontrolle mit einem RFID-gestützten Prozess und analysiert den Ein-fluss einzelner Kostenfaktoren auf das Gesamtergebnis. Dabei zeigt sich, dass der neue Prozess in Abhängigkeit von Leserate und Hardwarekosten in der Lage ist, die Leistungsfähigkeit des bisherigen Prozesses bezüglich Kosteneffizienz und Warenverfügbarkeit zu übertreffen.

This article reports on the Pertec (Pervasive RFID/Near Field Communication Technology and Applications) workshop, which discussed the future evolution of RFID beyond goods identification, including sensor integration, localization, NFC applications, and emerging challenges.

Retrieval algorithms of this type are referred to as constant data length (CDL) retrieval algorithms. We recently introduced a new retrieval algorithm called GCDL that generalizes the CDL retrieval algorithm: GCDL reads for a video stream i during k (DOT) mi, k (epsilon) , consecutive disk rounds a constant size block from the disk, which may results in a large read-ahead requiring a large amount of buffer. In this paper, we propose two new retrieval algorithms called static and dynamic GCDLb that minimize the number of reads during consecutive disk rounds while still maintaining continuous delivery to the client. COmpared to GCDL, we show that GCDLb requires less buffer per client and can admit more clients.

We assume that the I/O bandwidth of the server disk is limited. Given a certain I/O bandwidth, admission control decides whether or not a new client can be accepted without affecting the quality of service promised to the already admitted clients. Assuming variable bit rate (VBR) video streams, we consider an admission control policy with both, deterministic and statistical service guarantees for constant time length retrieval (CTL) and evaluate its performance in terms of the number of clients admitted
