Which facilities run out next month, and who nearby can lend them stock?

When donor-funded logistics analysts leave, county pharmacists still have to decide every month. Tandawa reads routine facility reports, forecasts next-month stockout risk, proposes lateral transfers before stock expires, and writes the county brief. The pharmacist decides; the tool never moves stock.

Next: validate in one county

Kisumu first. Lake-endemic malaria gives the forecast a strong seasonal signal, and the county mixes city hospitals with rural lakeside dispensaries close to a KEMSA regional depot. Six months of the county's real stock reports would replace every simulated number here and let us re-run the backtest on Kenyan data.
