Classes of VRP problems

Highlighted are classes of the problems SWAT currently supports solving. Stateless API support a superset of all common VRP problems.

Compound Zones: Setting Entry and Exit Time Penalties

Certain delivery or pickup areas, like large industrial parks, gated communities, or restricted city centers, require additional time simply to enter or exit the area, regardless of the specific stop location within it. These "compound zones" might involve navigating security gates, internal road networks, or specific traffic patterns. This model is supported by SWAT APIs using a compound_zones parameter to add these time penalties.

Distance Ratio Constraint

Optimizing route directness is crucial for balancing operational costs and carrier agreements. The distance ratio constraint allows planners to control how much a route can deviate from the most direct path, ensuring efficiency and cost predictability.
