Calculation method
Calculation method
Brews [start,end,batches,cups served,delay] (JSON)
At demand discard stock beyond hold limit. Use remaining cups, then brew ceil(unfilled/batch yield) sequential batches; start=max(demand−brew time,brewer free).
Unused or expired cups (count)
Expired leftovers plus leftovers after final demand event; final leftovers treated as eventual waste.
Symbols and units
- a
- Demand events [minute,cups]; enter JSON
- b
- Batch yield (cups)
- c
- Brew time per batch (minutes)
- d
- User maximum hold after completion (minutes)
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
- One brewer, fixed demand instants; whole sequential batches completed together when additional cups needed. Late completion is exposed. 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. Demand times nondecreasing; cup counts positive integers; batch yield>0; brew time>0; hold>=0. Preparation may begin before minute zero. Completion delays imply late service; not a food-safety hold recommendation.
