Dispatch planning

Shipment-ready times and due dates were used to compare consolidation policies that fill vehicles while preserving departure deadlines.

The operating decision

Shipping each lot as soon as it is ready can create many lightly loaded trips. Waiting to consolidate is useful only while due dates remain protected.

Inputs
Lot readiness · Order volumes · Shared due dates · Vehicle loads · Historical shipment records
Decision
Lots combined per delivery · Consolidation wait · Departure timing
Constraints
Shipment readiness · Due dates · Vehicle capacity · Immediate handling of already-late lots

How it is approached

  1. Gather ready volume

    Hold early-ready lots briefly when they can be shipped together on a fuller vehicle.

  2. Protect the deadline

    Depart when the due date is reached even if a truck is not full; do not let consolidation override the delivery commitment.

  3. Compare by supplier and period

    Replay shipment histories to inspect delivery frequency, fill and cost, keeping individual supplier examples separate from the wider tally.

Readiness and deadlines belong in the same plan.

When enough volume has gathered

Lots ready first are held briefly, then shipped together on one truck.

Due dateWaitReadyDeparture

When the due date arrives

Ready lots depart even if the truck is not full. Consolidation never overrides the due date.

Due dateReadyDeparture

When ready after the due date

Late lots are shipped without further waiting. Delays in readiness are checked separately.

A transport scheduling structure: consolidation is evaluated against readiness and due dates. The timelines illustrate dispatch rules, not a measured customer outcome.Scroll to explore the diagram ↔

Historical-order simulation

Validation & scope

The source compares simulations on historical shipments. An individual supplier timeline and the multi-supplier tally have different scopes, and effects varied by supplier. These are potential changes rather than savings realized after deployment.
