Abstract: We revisit the problem of categorizing demand patterns in order to select the best forecasting method. We improve the categorization scheme of Syntetos, Boylan and Croston (2004) by deriving an exact result for the boundary between categories and giving a simple approximation to the boundary that is better than that previously published.
Keywords: categorization; forecasting; inventory control; intermittent demand.
