- Visitors by interval
- 20,40,50,30
- Supply units per visitor
- 2
- Dispenser capacity (supply units)
- 150
- Refill every N intervals
- 2
- Interval [index,demand,unserved,end stock] (JSON)
- [[0,40,0,110],[1,80,0,30],[2,100,0,50],[3,60,10,0]]
- Total unserved supply units
- 10
Try another scenario
- Visitors by interval
- 30,50,60,40
- Supply units per visitor
- 2.5
- Dispenser capacity (supply units)
- 180
- Refill every N intervals
- 3
- Interval [index,demand,unserved,end stock] (JSON)
- [[0,75,0,105],[1,125,20,0],[2,150,150,0],[3,100,0,80]]
- Total unserved supply units
- 170
Calculation method
Calculation method
Interval [index,demand,unserved,end stock] (JSON)
Start full; refill to capacity at interval indices divisible by N, then consume min(stock,visitors×use).
Total unserved supply units
Sum interval shortages.
Symbols and units
- a
- Visitors by interval
- b
- Supply units per visitor
- c
- Dispenser capacity (supply units)
- d
- Refill every N intervals
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
- Consumable demand from observed visitor counts with periodic refill, deterministic stockout scenario. 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.
