Final answer:
The AFMC system that computes readiness based levels for selected XD items is the LIMS-EV, which helps manage the supply chain and maintenance needs of the Air Force.
Step-by-step explanation:
The Air Force Materiel Command (AFMC) system that computes readiness based levels for selected XD items is known as the Logistics, Installations, and Mission Support-Enterprise View (LIMS-EV). This system helps the Air Force in managing the supply chain and predicting the maintenance needs of its assets. It assists in determining the appropriate stock levels of various parts and equipment (XD items) to maintain operational readiness. The LIMS-EV system takes into account different variables such as historical usage rates and predicted future demand to compute the readiness-based levels (RBL) which ensure that the right items are available at the right time, without holding excessive inventory that could incur additional costs.
