Most inventory models assume that open orders arrive after a lead time that cannot be controlled by the inventory manager. However, in many situations inventory managers have the option to expedite open orders and they have to rely on sub-optimal heuristics to make expediting decisions. In this book the author incorporates an expediting level policy in a periodic-review base-stock inventory model and shows how the optimal solution can be computed. The solution approaches can be implemented easily and are capable of solving large problems efficiently. While the book is mathematically rigorous, the author presents important managerial insights gained from scenario analyses using data from the service division of a global equipment manufacturer. sakriti opis
