Routing Center: one-click optimization and drag-and-drop

How the PDPTW routing engine plans delivery+pickup routes in ~8 seconds, and how to fine-tune by dragging stops between vehicles.

Routing Center has the pending pool on the left and the route canvas on the right. Select orders, pick drivers/vehicles, then hit [One-click smart routing]. The engine (Solomon insertion + ALNS improvement, pickup-delivery pairs, LIFO loading check) returns in about 8 seconds: routes are created, and unassigned orders list their reason (time-window conflict, over capacity).

Drag-and-drop tuning#

• Drag a stop card from one vehicle to another: the system re-estimates ETA live and blocks the drop (red flash) if a time window would be missed or a pickup-delivery pair would be split.
• Reorder stops inside a route with ↑↓: the mileage/time delta shows live (“+2.3km, +8 min”).
• Completed stops are locked and cannot be dragged.

Pickup + delivery in one route#

Pickup stops use a blue 📦 icon, deliveries a green 📬 icon, and paired pickup-delivery orders are linked with a dashed line. The engine enforces the loading rule: a pickup’s goods may never block a later delivery (LIFO), so the sequence it produces is always loadable.
