How to use Cycle Time & Capacity

  1. Load the worked example to see the required input format.
  2. Estimate achievable capacity and compare demand with bottleneck capacity. Use consistent units, periods and definitions.
  3. Select Calculate, review the assumptions and export the result for your project evidence.

Formula and method

Capacity = available time × parallel resources × availability / cycle time; utilisation = demand / capacity.

Interpretation and assumptions

Assumes identical independent parallel resources and stable cycle time. Serial steps are constrained by the bottleneck. Allow for changeovers, quality losses and queueing separately.

Results support professional judgement. They are not a certification of process stability, a financial commitment or a substitute for study design.

Frequently asked questions

How do I use the cycle time & capacity?

Estimate achievable capacity and compare demand with bottleneck capacity. Load the example first, then replace all inputs with consistent process data and select Calculate. Capacity = available time × parallel resources × availability / cycle time; utilisation = demand / capacity.

What assumptions matter for cycle time & capacity?

Assumes identical independent parallel resources and stable cycle time. Serial steps are constrained by the bottleneck. Allow for changeovers, quality losses and queueing separately.
