# Mean Time Between Maintenance (MTBM) Calculation
## Step 1: Understand MTBM
**MTBM (Mean Time Between Maintenance)** is the average operating time between all maintenance events, including both planned and unplanned stops.
- **Planned Maintenance Stops:** Scheduled maintenance actions
- **Unplanned Breakdowns:** Unexpected failures needing repair
## Step 2: Gather Data
- **Total Operating Time:** \( 400 \) hours
- **Planned Maintenance Stops:** \( 5 \)
- **Unplanned Breakdowns:** \( 3 \)
**Total maintenance events:**
\[
5 \text{ (planned)} + 3 \text{ (unplanned)} = 8 \text{ events}
\]
## Step 3: Use the MTBM Formula
\[
\text{MTBM} = \frac{\text{Total Operating Time}}{\text{Number of Maintenance Events}}
\]
## Step 4: Plug In the Numbers
\[
\text{MTBM} = \frac{400 \text{ hours}}{8}
\]
## Step 5: Calculate MTBM
\[
\text{MTBM} = 500 \text{ hours}
\]
## Final Answer
**The Mean Time Between Maintenance (MTBM) is 500 hours.**
