1. What is Machine Uptime?

Machine uptime is a measure of the time a machine is operational and available for production versus the scheduled operating time. It's a key performance indicator in manufacturing and industrial operations.

2. How Does the Calculator Work?

The calculator uses the uptime equation:

Where:

• \( run\_time \) — Actual time the machine was operational (hours)
• \( scheduled\_time \) — Total scheduled operating time (hours)

Explanation: The equation calculates the percentage of scheduled time that the machine was actually running.

3. Importance of Uptime Calculation

Details: Uptime is crucial for measuring equipment reliability, identifying maintenance needs, and improving overall operational efficiency in manufacturing environments.

4. Using the Calculator

Tips: Enter run time and scheduled time in hours. Both values must be positive numbers, and run time cannot exceed scheduled time.

5. Frequently Asked Questions (FAQ)

Q1: What is considered good uptime percentage?
A: Typically 90-95% is considered good for most industrial equipment, though this varies by industry and machine type.

Q2: How is uptime different from availability?
A: Uptime measures actual running time versus scheduled time, while availability includes all potential operating time (24/7 for some operations).

Q3: What factors affect machine uptime?
A: Maintenance quality, operator skill, machine age, and production scheduling all significantly impact uptime.

Q4: How often should uptime be measured?
A: Typically measured daily or weekly, with longer-term trends analyzed monthly or quarterly.

Q5: Can uptime be greater than 100%?
A: No, uptime cannot exceed 100% as run time cannot exceed scheduled time in proper measurements.
