The reorder point (ROP), also reorder level (ROL) or "optimal re-order level", [1] is the level of inventory which triggers an action to replenish that particular inventory. It is a minimum amount of an item which a firm holds in stock, such that, when stock falls to this amount, the item must be reordered.
If there are backorders, the reorder point is: =; with m being the largest integer and μ the lead time demand. Additionally, the economic order interval [ 8 ] can be determined from the EOQ and the economic production quantity model (which determines the optimal production quantity) can be determined in a similar fashion.
The service level can be easily calculated in Excel by typing in the formula =normsinv(probability%). For eg entering =normsinv(95%) will return 1.65 as the answer. [10] and are the mean and standard deviation of lead time.

Total cost function and optimal reorder point [ edit ] The total cost is given by the sum of setup costs, purchase order cost, backorders cost and inventory carrying cost:
In (), the first order loss function [(,)] captures the expected shortage quantity; its complement, [(,)], denotes the expected product quantity in stock at the end of the period. [ 10 ] On the basis of this cost function the determination of the optimal inventory level is a minimization problem.
