Introduction to Maintenance Scheduling
Maintenance Scheduling problems involve planning preventive maintenance for machines. By staggering maintenance, you ensure that not all machines are down at once. You need to determine the maximum number of machines that can remain operational.
Prerequisites
How to Solve Maintenance Scheduling Problems
Step 1: Total machines = N
Step 2: Maintenance duration = D days
Step 3: Maintenance interval = I days
Step 4: With staggering, at most 1 machine in maintenance at a time (if D=1)
Step 5: Maximum operational = N - 1 (if D=1)
Step 6: For longer maintenance, may need to adjust
Example Problem
Example: 5 machines, each needs 1 day maintenance every 30 days. With staggering, how many operational at any time? Solution: Step 1: With 1-day maintenance, can schedule each on different days Step 2: One machine in maintenance, 4 operational Answer: 4 machines
Pro Tips & Tricks
- If maintenance duration = 1 day, can achieve N-1 operational
- If maintenance duration > 1 day, may need more machines down
- Minimum downtime = maintenance duration
- Maximum uptime = N - (maintenance_duration / interval × N) on average
