Recensione dell'articolo: (Hanalio˘glu, Tahir; Aksop, Cihan - " A sharp bound for the ergodic distribution of an inventory control model under the assumption that demands and inter-arrival times are dependent." - J. Inequal. Appl. 2014, 2014:75, 10 pp)

The main purpose of this paper is to investigate the ergodicity of an inventory control model with (s,S)-policy under the assumption that the amount of demands is dependent on inter-arrival times. In this context the authors describe the mathematical construction of the stochastic process x(t) that models the behavior of the system, and the ergodicity of the process is obtained under the assumption that the demands can be expressed as a monotone increasing function of the inter-arrival times.
