Kanban Bin Quantity with average daily usage of 50 units/day: a worked example
This worked example runs the kanban bin quantity numbers for a tougher week than the baseline: average daily usage of 50 units/day instead of the typical 100 units/day. Calculate the standard quantity per kanban bin by considering daily usage, replenishment frequency, and a buffer multiplier.
The inputs for this scenario
- Average daily usage: 50 units/day (the input this scenario stresses; the baseline uses 100)
- Replenishment frequency: 2 times/day (held at the documented default)
- Buffer multiplier: 1.2 x (held at the documented default)
Working through the calculation
- The calculation starts from the formula this tool documents: Bin Quantity = (Daily Usage / Replenishment Frequency) x Buffer Multiplier.
- Bin quantity (units per container) works out to 30 units at these inputs, and this is the headline figure for the scenario.
- Raw ratio works out to 25 value at these inputs.
- Conversion factor works out to 1.2 x at these inputs.
- Replenishment frequency works out to 2 value at these inputs.
How this compares with the baseline
- Against the tool's baseline example, where average daily usage sits at 100 units/day and the headline result is 60 units, this scenario comes in 50% below the baseline at 30 units.
- Use it when setting up point-of-use containers or tuning bin sizes after a delivery-frequency change. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.
Results at a glance
- Bin quantity (units per container): 30 units (headline result)
- Raw ratio: 25 value
- Conversion factor: 1.2 x
- Replenishment frequency: 2 value
