THE NUMBERS, EXPLAINED
How to use this calculator.
Two kitchen stations, each with pooled staff whose work can be divided evenly. All dish orders pass through both stations using supplied measured times; no task dependencies or queue timing.
Start with your inputs
Enter dish order counts, station 1 minutes per dish, station 2 minutes per dish, station 1 staff, station 2 staff, service window (min). Keep amounts in the units shown on each field. The example is a starting point, not a recommended value.
| Input | Example value |
|---|---|
| Dish order counts | 20,10 |
| Station 1 minutes per dish | 2,4 |
| Station 2 minutes per dish | 3,1 |
| Station 1 staff | 2 |
| Station 2 staff | 1 |
| Service window (min) | 60 |
A worked example
With the example inputs above, station demand (staff-minutes) is 80, 70. Change the inputs to explore your own scenario.
| Result | Example answer |
|---|---|
| Station demand (staff-minutes) | 80, 70 |
| Station utilization (%) | 66.666667, 116.666667 |
| Bottleneck station | Station 2 |
How this is calculated
Station demand (staff-minutes)
Multiply dish counts by each station’s per-dish work and add.
Station utilization (%)
Divide station work by staff count times service window.
Bottleneck station
Compare workload per staff member across the two stations.
Symbols and units
- a
- Dish order counts
- b
- Station 1 minutes per dish
- c
- Station 2 minutes per dish
- d
- Station 1 staff
- e
- Station 2 staff
- g
- Service window (min)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions and limits
Two kitchen stations, each with pooled staff whose work can be divided evenly. All dish orders pass through both stations using supplied measured times; no task dependencies or queue timing.
Calculations use the values you enter. Blank or invalid inputs show an error instead of silently substituting zero. Results are displayed to useful precision; calculations retain the underlying numeric precision.
Questions about this tool
What does the result tell me?
Station demand (staff-minutes); Station utilization (%); Bottleneck station. The result applies to the method and inputs described above. Check the units and assumptions before using it in a decision.
Why might another calculator differ?
Differences in units, rounding, timing or model definitions can produce different answers. Compare the input definitions and the method, rather than only the final number. For this tool: Two kitchen stations, each with pooled staff whose work can be divided evenly. All dish orders pass through both stations using supplied measured times; no task dependencies or queue timing.
