What is the average endurance level of a repair part designated as a SIM item?

The average endurance level of a repair part designated as a SIM (Strategic Inventory Management) item is 75 days. This measure indicates the period for which the inventory of SIM items is expected to last under average operating conditions, ensuring that the supply chain can effectively manage availability while balancing the costs associated with carrying inventory. In this context, SIM items play a critical role in maintaining operational readiness and efficiency, as they are essential for supporting mission-critical systems and equipment.

An endurance level of 75 days helps in planning and forecasting inventory needs, enabling logistics specialists to make informed decisions about resupply and inventory management practices. It strikes a balance between the necessity of having enough parts on hand to avoid delays in maintenance and the need to minimize excess inventory, which can lead to higher holding costs. Therefore, understanding this average endurance level is vital for effective logistics operations within the Navy.
