Abstract. UHF-RFID is a mature and widespread technology that has the potential to increase the
reliability and efficiency of processes in logistics and production environments.
However, complex interference effects in indoor environments pose challenges to the implementation
of reliable wireless communication systems like RFID.
This work proposes a method for tag performance evaluation utilizing a coherent two-stage rating process.
This enables the abstraction of physical quantities and facilitates the interpretation of tag readability.
For this purpose, two well-established full-wave techniques are utilized to perform deterministic simulations
of a logistical UHF-RFID use-case.
The setup of large-scale simulation environments is discussed and important quantities to be considered in
RFID-systems are derived.
Based on the simulation results and the proposed rating method, the RFID use-case is evaluated.
Results are visualized in full-3D, facilitating the identification of critical spots.
Furthermore, a subsequent cross-validation of the simulation results is performed, verifying the validity of the simulation results.
By performing a priori propagation analysis, issues can effectively be revealed beforehand and costly modifications
after system deployment can be avoided.
Diese Frage stellten sich die Studierenden verschiedener Hochschulen aus Deutschland und Österreich als Teilnehmer beim Studierendenprogramm des diesjährigen Materialflusskongresses. Neben der Teilnahme am Kongress wurde den Studierenden ein vielseitiges Begleitprogramm mit Exkursionen und Networking angeboten.
Due to their systemic relevance, a high availability of intralogistics systems is crucial. This requires the stockpiling of capital-intensive spare parts. Strategies are therefore needed to reduce the severe capital commitment for spare parts management. No practical recommendations and solutions for this problem are available however. This contribution describes strategies and procedures for a cooperative inventory poolingsystem and our model of a simulation-based analysis of inventory levels for low demand spare parts in these systems. We determine that companies can gain benefits and greatly lower their inventory level and associated costs when cooperating in spare parts management. Furthermore, we investigated effects of changing network compositions while cooperating over time.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
