How batch size is optimized
Each block explains one part of how this works and how to read the result.
Constraint model
The recommended batch size is the minimum of physical room capacity and your preferred teaching size (pedagogy/quality cap).
Batches needed = ceil(demand ÷ recommended size). Leftover demand appears when you intentionally run fewer batches.
Source
recommendedSize = min(roomCapacity, preferredSize); batchesNeeded = ceil(demand ÷ size). Revenue = studentsServed × fee. Planning model for coaching institutes — not a guarantee of fill rate.
Frequently asked questions
Should preferred size be lower than room capacity?
Often yes — a 60-seat room may teach better at 40. The optimizer respects your pedagogy cap.
Does it account for dropouts?
No — use expected enrolled demand, or lower demand by your historic show-up rate.
Can I model multiple rooms?
Run once per room type, or set room capacity to total parallel seats if batches run simultaneously.
Is fee required?
Only for the revenue estimate — leave fee at 0 if you only need size/batch counts.
