Abstract
Kruse and Kaplan (Kruse, W. K., A. J. Kaplan. 1973. Comments on Simon's two echelon model. Opns. Res.21 1318–1322.) identified a logical flaw in a paper by Simon (Simon, R. M. 1971. Stationary properties of a two-echelon inventory model for low demand items. Opns. Res.19 761–773.), which modeled a two-echelon inventory system composed of a number of independent bases using S − 1, S replenishment policies, and a common depot using a more general R, Q type policy.
