Spare Parts Procurement Process
Procurement and Inventory Management Process
The Procurement and Inventory Management Process is inventory control software stored on radiation-hardened NOR flash that tracks micrometeoroid and orbital debris spare consumption and schedules automated replenishment. Consuming 0.5 watts, the routine monitors replacement events via the L1-DVT ledger and triggers L1-MFG fabrication orders whenever stock falls below a 30 percent reorder threshold. Operating across a 100-year planning horizon, the system manages lunar supply isolation by factoring in-situ resource utilization manufacturing lead times directly into safety stock calculations, retiring aging-out components, and sustaining a 500,000-hour mean time between failures.
Procurement and inventory management process tracking MMOD spare consumption, scheduling replenishment, and integrating with L1-MFG production planning.
Purpose
Procurement and inventory management process tracking MMOD spare consumption, scheduling replenishment, and integrating with L1-MFG production planning.
Context
Child of L2-MMD-SPARE within the Lunar Ark system
