Reorder Point Techniques

Systems based on reorder points assume that demand is uniform and predictable and that there is no true identifiable time of need. Hence, stock must always be available. In practice, demand is discontinuous and follows a lumpy pattern. Stock is seldom depleted item-by-item, it is more common to deplete or order by lots or batches. This ordering in lots tends to magnify the requirements or lot sizes from the finished item to the component to the raw material levels.
