Page guide

Compare serial production stages, account for parallel stations and find every tied capacity constraint.

How to use Cycle time bottleneck calculator
  1. Add the process stages in order and enter cycle time for one station at each stage.
  2. Enter the number of identical parallel stations and choose the cycle-time unit.
  3. Compare stage capacities and all tied bottlenecks, then download the full report.

Useful next steps

The slowest effective stage limits the rate

Divide cycle time by parallel station count to find each stage’s effective cycle. The largest effective cycle gives the theoretical line limit. Stages with equal limiting capacity are all marked as bottlenecks.

A capacity bound, not a queue simulation

The calculation assumes identical independent parallel stations. It does not model setup time, breakdowns, shared workers, starvation, blocking or queues. First-unit processing time in the report adds the individual stage cycle times and excludes waiting.
