    • 4. Maintenance work orders processed per unit time
    • 5. The average administrative delay time
    • (the average time from when an item is initially received for
    • maintenance to the point when active maintenance on that
    • item actually begins).
  11. What are Spares, Repair Parts, and Related Inventory Factors
    • Spares/repair part quantities are a function of demand rates and
    • include consideration of the following:
