MihsabaHow to use
Estimate nominal capacity and capacity adjusted by your realization factor from parallel resources, hours and units per hour.
- Enter matching-period inputs with consistent units: Number of parallel resources or machines, Working hours per resource in the period, Nominal rate per resource (units/hour), Capacity realization factor (%)
- Nominal capacity = parallel resources × hours per resource × rate; adjusted = nominal × realization factor ÷ 100
- Calculate, then check data definitions and assumptions in the note before comparing with another period.
How it is calculated
Example
Three machines, each working 8 hours at 50 units/hour, give nominal capacity of 1,200 units. At an 80% realization factor, adjusted capacity is 960 and the gap is 240 units.
Important notes
Addition assumes independent parallel resources with the same hours and rate. Serial line stations cannot be added this way because the bottleneck constrains output. The realization factor is your planning input, not measured OEE or automatically calculated utilization. If hours already exclude downtime, do not deduct the same loss again in the factor. Fractional estimated units are not completed saleable units.
Worked examples and interpreting results
Three machines, each working 8 hours at 50 units/hour, give nominal capacity of 1,200 units. At an 80% realization factor, adjusted capacity is 960 and the gap is 240 units.
| Case | Calculation | Result |
|---|---|---|
| Nominal capacity | 3 × 8 × 50 | 1,200 |
| Adjusted capacity | 1200 × 0.80 | 960 |
How to check the result

Frequently asked questions
Can I add machines in one serial line?
Use the line bottleneck rate as one resource, or enter the number of independent parallel lines.
What does an 80% factor mean?
It assumes realizing 80% of nominal capacity for this period; the calculator does not identify the causes of the gap.
Are the starting inputs my actual data?
They are only the worked example. Replace them with your data and press Calculate. Editing an input clears the old result.
