Examples
Try the starting example
- Guest visits per interval (count)
- 10,20,15,8
- Towels issued per guest
- 1.2
- Return-and-wash delay (intervals)
- 2
- User reserve fraction
- 0.1
- Peak towel par (count)
- 47
- Total modeled towel issues
- 63.6
Try another scenario
- Guest visits per interval (count)
- 15,25,20,10
- Towels issued per guest
- 1.5
- Return-and-wash delay (intervals)
- 3
- User reserve fraction
- 0.15
- Peak towel par (count)
- 104
- Total modeled towel issues
- 105
Calculation method
Calculation method
Peak towel par (count)
ceil(max rolling guest sum over delay intervals×issue rate×(1+reserve)).
Total modeled towel issues
Sum guests×issue rate.

Assumptions & limits
Assumptions & limits
- Towel issue-return as discrete intervals, with a user-estimated combined return-and-wash delay. 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.
