Relationship constraint definitions

The relationship constraint builder allows you to define relationships between entities (sites, customers, products, assets, or shipments) that must be forced or prevented when building routes.

Use the builder to select one or more records for the first part of the relationship, and then select one or more records to create the second part of the relationship. Once the two parts of the relationship have been selected, you can define the type of relationship: one of Force or Prevent.

The following combinations are supported:

Entity A	Entity B	Relationship
Shipment	Shipment	Prevent Note: This combination is not supported for Periodic Optimization (Periodic VRP).
Product	Product	Prevent
Shipment	Transportation Asset	Prevent and Force (Force constraints permit ONLY the specified transportation assets to carry the shipment)
Product	Transportation Asset	Prevent and Force (Force constraints permit ONLY the specified transportation assets to carry the product)
Site	Transportation Asset	Prevent and Force (Force constraints permit ONLY the specified transportation assets to visit the site)
Site	Site	Prevent
Site	Customer	Prevent
Customer	Transportation Asset	Prevent and Force (Force constraints permit ONLY the specified transportation assets to visit the customer)
Customer	Customer	Prevent
Customer	Site	Prevent

Relationship constraint builder example

In this example, we force a product called "Perishable Food" to be routed on a transportation asset called "Refrigerated Truck":

Open the Relationship Constraints table.
Click Constraint Builder. You see the Relationship Constraint Builder form.
For Condition A, select the table drop the Type drop-down list. In the example, select “Transportation Assets”.
Select the record(s) to be included in the constraint. In this example, select “Refrigerated Truck”.
In the Relationship drop-down, select “Force”.
For Condition B, select the table drop the Type drop-down list. In the example, select “Products”.
Select the record(s) to be included in the constraint. In this example, select “Perishable Food”.
Click Build. Records are added to the Relationship Constraints table based on the values you have selected in the constraint builder.
