Comments on a Simple Method to Compute Economic Order Quantities.

This study examines several papers to study inventory models with back orders to provide a simpler solution procedure for EOQ/EPQ inventory models by using Arithmetic Geometric Mean inequality or Cauchy Bunyakovsky Schwarz inequality. We will point out that a paper implicitly adopted the fill rate from a published article without proper citation to convert two-variable minimum problems into one-variable problems. Hence, his simpler solution procedure is standing on the shoulder of a giant. We also provide detailed examinations for other three related papers that was related to our studied article to point out their contributions and questionable results. [ABSTRACT FROM AUTHOR]
