Models for Cost-Benefit Analysis of RFID Implementations in Retail Stores
This paper focuses on the models for analyzing passive RFID tag implementation in a supply chain comprised of the manufacturer, distributor, retailer and consumer by looking at costs of tag readers, communication network costs and other infrastructure costs.
Background:
 Various retailers and manufacturers have implemented RFID solutions with great success.
 For the analysis of this paper, the researchers are assuming the passive RFID tags are applied at the item, case, and pallet level.
 RFID infrastructure for tag reader networks can be classified in 3 groups: wired, wireless and mixed.
o Wired networks can provide high speed networks for tag readers as well as power the reader. However the primary advantage for this is that store shelves have to be wired as well.
o Wireless networks can provide high speed networks at a low initial cost but the operational cost can be higher over time when compared to a wired network. The main danger with wireless networks is they are more prone to hacks.
o Mixed networks can provide benefits of wired network robustness and low maintenance costs.
 A formulation for each cost and benefit is provided in the paper and could be of great use for someone looking to quantify the impact of RFID.
