Courier pickup and delivery
Order assignment and courier visit sequences were considered together, with pickup precedence and courier capacity checked for every proposed run.

The operating decision
Assigning an order changes a courier’s whole route. Every pickup must precede its delivery while time and capacity remain feasible.
- Inputs
- Incoming orders · Courier positions · Pickup points · Delivery points
- Decision
- Courier assigned to each order · Visit sequence for each courier
- Constraints
- Pickup before delivery · Courier time limits · Courier capacity
How it is approached
Read orders and couriers together
Combine the pickup and delivery points of incoming orders with the positions of available couriers.
Build a complete run
Change assignment and visit sequence together, rather than selecting a courier independently of the route that follows.
Check feasibility and delay
Check pickup precedence, available time and capacity, then compare feasible runs under the same delay objective and computing budget.
Every pickup changes the route that follows.
Static evaluation
Validation & scope
Static regional problems were compared with a baseline under matching objectives and computing time. Improvement varied with the evaluation condition; the source includes a cutoff condition with no improvement. A separate dynamic trial is described in a summary and is not treated as equivalent evidence.
