What characterizes a compact disc (CD) inventory model?

The correct answer focuses on an inventory management model that optimizes the ordering and replenishing of low-cost, frequently used items. This characteristic of the compact disc inventory model highlights its efficient approach to manage items that may have a lower individual value but are consumed or sold frequently.

This model typically employs strategies such as just-in-time ordering, which minimizes holding costs and reduces the risks associated with excess inventory. Since low-cost items are often needed in large quantities and have a steady turnover rate, optimizing their ordering and replenishing can significantly enhance operational efficiency and reduce waste.

In contrast to this, the other options do not accurately reflect the nature of a compact disc inventory model. For instance, managing perishable goods would require a different approach, focusing on shelf life and expiration, which doesn't align with the non-perishable nature often associated with compact discs. Similarly, focusing solely on high-value inventory would not make sense in the context of compact discs, as they generally fall into the low-cost item category in inventory management. Lastly, a model designed exclusively for digital products is not relevant since compact discs are physical items, thus requiring distinct inventory management practices compared to digital goods.
