A Comparison of Arrival Algorithms for Automated Serial Claiming Operations.
Christensen, John O.
Heretofore, methods of claiming missing issues of serials publications have been ad hoc. The study describes four methods of claiming and analyzes the performance of three of the methods on 16 arrival patterns of serials. The arrival patterns, selected as workable examples from a random sample of the Kardex files at the University of Utah, were graphed against a statistically-based claiming algorithm and two algorithms based on the arrival frequency plus a lag factor. The statistically-based algorithm produced more false claims and usually claimed issues sooner than the algorithm based on the lag factor. The statistically-based algorithm worked best with the medium frequency (monthly, quarterly, etc.) serials and the lag factor algorithm appeared to work best with the long- and short-frequency (annuals, weekly, etc.) serials.
