How batch size is optimized

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.
