Each page below picks one vertical and stacks its most distinctive constraints onto a single realistic payload — a small fleet and a handful of stops, not the isolated mechanism-by-mechanism examples in the guides. Use them to check, at a glance, whether Kardinal’s constraint model fits how your operation actually works.

Parcel & express

PUDO gated by capacity, driver zone preferences, a mixed last-mile fleet, predictive traffic.

Waste collection

Alternative disposal outlets, material changeover time, incompatible loads, heavy-vehicle routing.

Cold-chain last-mile

Single-mode-at-a-time refrigerated compartments, trusted-keychain deliveries, zone preference, predictive traffic.

Field services

Preferred seniority on demanding jobs, opportunistic scheduling, a travel-distance cap between jobs, technicians starting from home.

Bulky & heavy goods

Capacity-gated customer returns, a subcontractor revenue floor, equipment-dependent service time, two-person crews.

Heavy long distance

Reserved warehouse slots, load-aware CO2 accounting, self-closing consolidation loops, a real overnight rest.

Retail last-mile

Key-holder-only access windows, blended subcontractor/in-house costs, pre-opening store drops, trusted-keychain deliveries.
