We show that long-run average cost function for the (R, T) policy with normally distributed demand has a structure similar to that of the corresponding (Q, r) model so that many of the useful properties of the latter model are applicable. In particular, (i) the optimal cost is relatively insensitive to the choice of the reorder interval, T, provided a near-optimal R corresponding to the chosen ...
