Spare parts inventory represents a significant capital investment and is vital to minimizing production downtime. This course provides comprehensive strategies for managing maintenance, repair, and operating (MRO) inventory effectively. Participants will learn how to balance the risks of stockouts against the costs of overstocking by applying modern inventory control techniques. We will cover classification, accurate forecasting, warehouse organization, and cycle counting to ensure that the right part is available at the right time and at the optimal cost, transforming the storeroom from a liability into a strategic asset.
