Cash where it is needed, not everywhere
Idle cash in branches and ATMs is capital earning nothing, and stock-outs are a service failure. Forecasting withdrawals per location turns replenishment routes and holdings into a solvable trade-off.
Optimization and forecasting for institutions where every decision has to be explainable after the fact. A model that cannot show its reasoning is not usable here, whatever its accuracy.

Treating every delinquent account the same spends the most expensive channel on the least recoverable balances. Ranking by expected value directs contact where it pays.
Accuracy alone does not clear model risk review. Optimization gives an auditable objective and explicit constraints. The reasoning is the artefact, not a post-hoc explanation of a black box.
