Inventory Operation Performances versus Read Memory Size.
1 Objective:
At a meeting of the RFID Data model for libraries working group, held on the 1 st March,
2005, TAGSYS offered to explore the simulation of performance of key library RFID
operations versus read memory size. Bibliotheca and FKI offered to support this task. The two
library operations which were proposed as being the most sensitive to memory size were the
reading of books on conveyer sorting equipment and the inventory of books on library
shelves.
Unfortunately, the mathematical modeling simulation software that TAGSYS expected to use
for this activity, SIMTAG, proved not suitable for this simulation. Consequently, TAGSYS
has resorted to performing empirical tests to explore how the performance of a given library
operation may be degraded by selecting too large a memory size.
TAGSYS has selected the Book Inventory Operation as the most demanding operation for
speed and accuracy of reading. All testing was performed with an ISO18000, part3, Mode 1,
air interface protocol.
