- Peak served covers per hour (covers/hour)
- 60
- Glass types [name,glasses per cover]; enter JSON
- [["Water",1],["Wine",0.5]]
- Wash-return turnaround (minutes)
- 30
- Breakage and reserve fraction
- 0.1
- Required glassware by type (JSON)
- {"Water":33,"Wine":17}
Try another scenario
- Peak served covers per hour (covers/hour)
- 80
- Glass types [name,glasses per cover]; enter JSON
- [["Water",1],["Wine",0.75]]
- Wash-return turnaround (minutes)
- 45
- Breakage and reserve fraction
- 0.15
- Required glassware by type (JSON)
- {"Water":69,"Wine":52}
Calculation method
Calculation method
Required glassware by type (JSON)
For each type ceil(covers/hour×turnaround/60×glasses/cover×(1+reserve)).
Symbols and units

Assumptions & limits
Assumptions & limits
- Deterministic peak glass demand over one wash turnaround; reserve is user-supplied and not a standard. 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.
