-Exponential Smoothing, which is unbiased on non-intermittent and stochastic intermittent demand, decays hyperbolically when obsolescence …

Spare parts are known to be associated with intermittent demand patterns and such patterns cause considerable problems …. Compound distributions have been used to model intermittent demand patterns; there is however a lack of theoretical analysis …

Intermittent demand time series involve items that are requested infrequently, resulting in sporadic demand. Croston … accuracy error metrics for model evaluation for intermittent demand time series. Consequently these may be inappropriate for … metrics, along with two novel ones for parameter optimisation for intermittent demand methods. The proposed metrics are found …
