Why this matters

Confidence84%

Harvest-to-mill time at Mill A rose from 17 h to 26 h this week and explains 27% of the Mill A OER decline (22.3% → 21.6%). Older FFB builds free fatty acids and loses oil. The dispatch optimizer re-sequences truck pick-ups to evacuate the oldest ripe crop first and smooths arrivals at the mill.

OER effect · Mill A

Run the optimizer to estimate recovered OER.

H2M share of decline 27% × 0.7 pp, pro-rated by hours recovered vs the 9 h increase.

Solver notes

All constraints satisfied with slack; plan prioritises oldest ripe FFB at CP (restan) first.

Fleet utilization 79%Mill intake load 98%All constraints satisfied

Estimated impact based on synthetic scenario assumptions. Dispatch plans are decision support — the transport coordinator confirms before release.
