Understanding TO Inputs: Orders, Master Data and Dispatch Constraints

Based on POL-TMS-020, this guide distinguishes optimization order attributes, vehicle and facility master data, and dispatch policies, with practical data checks.

Dispatch engine input does not consist solely of an order list. POL-TMS-020 explains how transport orders (F/O), associated masters, and constraint policies by shipper, region, and transportation pattern are referenced together.

What to prepare for your shipping order

Master to associate with the order

  • Vehicle specifications and available vehicle pool
  • Latitude and longitude of the facility, operating hours, loading and unloading times, vehicle types available for entry
  • Non-working days associated with the target time window
  • Routes or candidate Hubs required for the selected engine
  • Product group combinations and standard codes that cannot be mixed together

Conditions determined by the dispatch policy

Manage engine use and type by shipper, region, and transportation pattern, objective function (distance/freight), upper limit of one-time call order, minimum/maximum stop/distance/loading ratio, maximum operation time, depot return, and time window strength.

HARD time windows are treated as hard constraints regardless of relaxation settings. Priority is managed using standard codes, and units are specified for weight, volume, and quantity. The call upper limit is not a guaranteed performance figure, but an operational setting to be determined considering licenses and available resources.

What this document does not specify

POL-TMS-020 defines the input reference range. The actual field types, DB columns, and overall API request/response schema of order/master follow separate definitions and applied versions. Nor does it mean that all algorithms listed in the policy are built into the same version.

YOUR OPERATIONS / NEXT STEP

How do we apply dispatch and replanning to our work?

Please tell us about the most difficult situation in dispatch right now. We review the required data, site constraints, and scope of connection with existing systems.

Please choose a situation that is close to our company.

Having these materials will be helpful in your review.

  • Representative order/vehicle items
  • Operational restrictions such as delivery time and vehicle type
  • Current dispatch method and examples of changes

Even if you don't have any data yet, you can tell us about your current situation. Information that is difficult to disclose may be reviewed as a sample with identifying information masked.

In consultation, the scope is set as follows.

  1. Check current work and improvement goals
  2. Summary of data/constraints and comparative verification scope
  3. Link to existing systems and discuss scope of construction
