Maintenance Schedule Optimizer
MILP-Based Schedule Optimizer
The MILP-Based Schedule Optimizer is a software component stored on radiation-hardened NOR flash that allocates maintenance tasks and robotic resources across settlement subsystems. Drawing 2 watts of power with a 500,000-hour mean time between failures, it executes mixed-integer linear programming algorithms every 6 hours to coordinate servicing within strict power limits, spares availability, and equipment downtime windows. Sustaining autonomous scheduling across a 100-year operational lifetime requires managing solver runtimes through heuristics and ingesting authenticated updates, directly balancing task urgency against resource efficiency.
Mixed-integer programming schedule optimizer assigning tasks to L1-MNT/L1-ROB resources within constraints (power, downtime windows, dependencies).
Purpose
