In this paper we present the efficiency measurement study of past stock movement simulation designed for the stock management of products with intermittent demand. The proposed simulation is able to provide the combination of controlled parameters (reorder stock level + order quantity/order-up-to level) included in two
frequently used stock management policies (Q-system, PQ-system) which guarantees the minimal stock holding and ordering costs and the required fill rate. To obtain reorder stock level single exponential smoothing, Croston’s method, the modification of Croston’s method made up by Syntetos&Boylan and Levén&Segerstedt, the method of Smart and the total enumeration are considered. When tested on 5730 real
intermittent demand series from automotive industry we conclude that the total
enumeration used in the past stock movement simulation to calculate reorder stock
level leads to the lowest stock holding and ordering costs and represents robust
approach in intermittent demand stock control in term of increasing intermittence and lumpiness.
