WebMay 31, 2016 · METHOD-V CROSTON. Introduction: Its modification of exponential smoothing for sporadic demand product time series was suggested by Croston in 1972. The core value of this method is not only the estimation of average demand volume but also the estimation of time interval length between two non-zero demands, a term called as … Webalthough some production management texts suggest the lesser-known alternative of the Croston method [5]. In their experimental study, Johnston and Boylan [9], after using a wide range of simulated conditions, observed an improvement in forecast performance using the Croston method when compared with the straight Holt (EWMA) method.

In Croston’s algorithm, the historical demand is separated into two series: one representing the non-zero demand and the other representing inter-arrival time. The inter-arrival time is identified as the period between two consecutive non-zero demands.
