Tiivistelmä: | This study was initiated and supported by a manufacturer of mail processing equipment, which offers service contracts on its equipment and stocks spare parts to support the maintenance function. To find an effective stocking policy, this study formulates a constrained optimization model with the objective minimizing overall inventory investment at the distribution center subject to constraints on customer service and order frequency. Three heuristic algorithms are developed, based on simplified representations of the inventory and service expressions, and these lead to easily implementable inventory policies in which the control parameters for a newly introduced part can be computed in closed form without reoptimizing the rest of the system. |
