Parallel Station Capacity Calculator
Use this calculator when deciding whether duplicate stations, parallel fixtures, or multiple inspection benches can satisfy a takt or throughput requirement. It turns parallel capacity into good output for line design decisions.
What this calculator does
- Calculate capacity from parallel stations, cycles per station, uptime, and yield.
- a line layout planner needs to know how many parallel stations are required to remove a bottleneck
- The result estimates good hourly capacity from parallel stations performing the same work.
Formula used
- Gross parallel capacity = parallel stations × cycles per station-hour
- Good parallel capacity = gross capacity × uptime × yield
Inputs explained
- Parallel stations installed: Count stations that can run the same operation independently.
- Available cycles per station-hour: Use the capacity of one station over one hour.
- Parallel station uptime: Use average uptime after faults, tool changes, and operator waits.
- Good output yield: Use good units after station rejects and retests.
How to use the result
- Use it before buying duplicate equipment, adding benches, or changing labor assignments.
- It assumes stations are truly independent and not limited by one shared feeder, robot, tester, or operator.
Common questions
- What is Parallel Station Capacity for? Calculate capacity from parallel stations, cycles per station, uptime, and yield.
- What information do I need before using it? You need parallel station count, cycles per station-hour, uptime, and yield.
- When is the result only an estimate? The result is approximate if station cycle times vary, a shared resource gates all stations, or routing logic creates uneven loading.
- How can I use the result on the line? Use the capacity result to compare against takt and decide whether another parallel station is justified.
