Description
Multiply demandPerDay by leadDays and 1 + safetyFraction for requiredUnits.
Production capacity terms compare available time, demand, cycle time, and buffer use. A scalar average or count budget can hide task constraints and process variability.
Multiply demandPerDay by leadDays and 1 + safetyFraction for requiredUnits.
When to use this tool
Use Kanban Safety Container Rounding Gap when you need a transparent capacity, takt, or workload component.
How to use the tool and how it works
- Enter demandPerDay, leadDays, safetyFraction, containerUnits. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read requiredUnits, unroundedContainers, containers, excessCapacity. Use the output convention below.
Multiply demandPerDay by leadDays and 1 + safetyFraction for requiredUnits. Divide by containerUnits and round upward for containers, returning the resulting excessCapacity.1

}Limitations and assumptions
- Safety fraction is an explicit uplift, not a service-level estimate; no demand distribution, replenishment feasibility, or inventory policy is fitted.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Validate the complete process, resources, and variability before converting a local budget into a production plan.
