- 30
- Stage handling durations (minutes/item)
- 3,4
- Average retained days (count)
- 5
- Storage footprint per item (litres)
- 1.5
- Handling workload (staff hours/day)

- Storage volume (litres)
- 225
Calculation method
Calculation method
Handling workload (staff hours/day)
Items×sum stage minutes/60.
Steady-state retained items (count)
Items/day×retained days, assuming arrivals equal disposals in steady state.
Storage volume (litres)
Retained items×volume/item.
Symbols and units
- a
- Items received per day (count)
- b
- Stage handling durations (minutes/item)
- c
- Average retained days (count)
- d
- Storage footprint per item (litres)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- Measured per-item handling stages and constant daily arrivals; Little-style storage bookkeeping under a supplied retention duration. Supported limits: All numeric inputs and computed intermediates must remain finite. Supported numeric input magnitude is zero or 1e-12 through 1e12 in absolute value; reject values outside this bounded range. All lists/JSON record tables are limited to 100 records unless a stricter bound is stated; reject malformed record arity and wrong member types. All numeric values must be finite. Lists contain at most 100 records; required lists must be nonempty. Rates, probabilities and fractions are entered as fractions, not percentages; fractions must be between 0 and 1. Use a single consistent user-selected currency for all amounts; no exchange-rate conversion.
