May 31, 2016 · The Croston method is a forecast strategy for products with intermittent demand. In the univariate forecast profile, choose forecast strategy. Croston’s can be easily emulated with exponential smoothing and any timing benefit is usually adjusted by order lot sizing, and or safety stock in supply planning . The analysis method is compared with the result of the same field research before and the geology research before in Sangon II to make analysis the source of Mercury in the groundwater.The results of Mercury in the groundwater are 3 samples of the groundwater had contained Mercury ( S1 = 0,00030 mg/L at 550 m distance from the ore processing ...
I wouldn't say there is a strictly better method. We should use a scientific approach here: test different methods and see which one gives the best result (against a proper test data set). Initialization: level, trend & forecast. We will initialize the first forecast as a null value, and the second forecast point as simply the first observation.To initialize Croston’s approach, we use the time until the first event and the size of the first event. The DPUT variance when using this method can be expressed as: Var Y = σ C R O S T 2 = 1 T + m ∑ t = T + 1 T + m y t − μ C R O S T 2. Croston’s method also considers LTD with a constant LT and normal statistical distribution.
