The models

Six models. One engine.

Each model is built for a distinct class of logistics problem, configured through standard rules rather than custom code. Every model shares the same interface, road network and cost model: send the problem, and get back the optimised plan, the exact cost breakdown and the specific rule behind any unscheduled task.

Solve actions: Optimise (full solve), ReOptimise (mid-shift update around committed stops) and Evaluate (score any existing plan on the same cost model and flag every broken rule).
Road network: Built-in road distances and travel times. Live today across the United Kingdom, Ireland, Australia, New Zealand and Southern Africa, with continental Europe in rollout. Additional regions provisioned on request.
Interface: Stateless HTTPS API with Protobuf and JSON/OpenAPI payloads, scoped by team API key. Includes an Excel add-in for analysts running plan benchmarks and network studies.

Vehicle router

IVR7

High-speed operational routing.

Sub-second capacitated routing with time windows, mixed fleets and multi-dimensional costs, all configured in the schema rather than written as custom code. Built for everyday distribution, it leaves out tanker compartments and cross-route dependencies, which makes it the fastest model to ship and to re-plan mid-shift.

Built for: Daily pickup and delivery fleets, live dispatch boards and the first integration a TMS team ships
Core constraints: Multi-dimensional capacities, time windows, driver shifts and breaks, vehicle-to-stop compatibility
Mid-shift re-optimise: 0.3 s median around committed stops
Production volume: About 128,000 routes returned, January 2025 to October 2026

Vehicle router

IVR8

Full-constraint industrial routing.

Engineered for the constraints that break standard solvers: multi-compartment loads, regional driver fatigue rules, complex inter-task dependencies and heterogeneous fleet structures. Everything in IVR7 is included. The model behind most of Icepack's production volume.

Built for: Multi-compartment and regulated fleets, and TMS platforms serving many clients from one engine
Core constraints: Multi-compartment loads, driver fatigue rules, inter-task dependencies and mixed fleets, plus the full IVR7 constraint set
Largest request: 1,399 jobs in a single request
Production volume: About 324,000 routes returned, January 2025 to October 2026

Periodic delivery

NDD

Nominated delivery days.

Co-optimises delivery-day selection and daily vehicle routing across a multi-day horizon. Instead of planning each day in isolation, NDD decides on which days of the week or month each customer order is served, respecting frequency and day-spacing rules, while building the capacitated vehicle routes for every day simultaneously.

Built for: Fixed-cycle retail replenishment, wholesale distribution and multi-depot weekly delivery plans
Core constraints: Delivery frequency and day-spacing rules, allowed day patterns, daily fleet capacity smoothing, plus the full IVR constraint set
Production volume: About 7,900 multi-day routes returned, January 2025 to October 2026

Periodic territories

NVD

Nominated visit days.

Simultaneous territory design and multi-week visit scheduling for field teams. NVD assigns customers to territories, selects the visit days across the cycle to meet call-frequency targets, and sequences each rep's daily route on real roads. Because territory design is a trade-off between travel cost and fair workload, the solver is natively multi-objective, returning the full Pareto frontier of optimal plans in a single pass.

Built for: Field sales and merchandising estates, recurring technician and inspection rounds, and territory restructures
Core constraints: Call frequency and spacing across multi-week cycles, rep-to-customer continuity, territory contiguity and daily shift limits
Multi-objective frontier: Pareto frontier, lowest travel cost against best workload balance
National scale: 2,920 stores and 4,721 visits across 106 territories over ten days, solved in about 15 minutes with none dropped

Street-level

ISR

The street router.

Standard vehicle routers visit nodes; ISR traverses edges. In high-density kerbside operations, the road segment itself is the work. ISR consolidates thousands of individual bins, meters or kerb segments onto directed street arcs and sequences continuous, capacitated rounds, enforcing side-of-road service, heavy-vehicle turn restrictions and zero illegal U-turns from start to tip.

Built for: Waste and recycling collection, street sweeping, and postal and meter rounds
Largest round: 2,708 jobs in a single request
Dense round: 735 of 735 collections sequenced
Production volume: About 34,000 routes returned, January 2025 to October 2026

Network design

NS3

Network sourcing.

Optimises supply chain flow and facility footprint across three tiers: production sites (plants, farms, suppliers), intermediate hubs (warehouses, cross-docks, depots) and customer demand points. NS3 determines where to source, store and ship volume to meet demand at minimum total cost, answering the upstream network questions before a single vehicle route is planned.

Built for: Depot openings and closures, factory-to-DC sourcing, volume-shock stress tests and end-to-end network flow studies
Core constraints: Plant-specific product capabilities, ambient and chilled flows, warehouse floor-space and pallet throughput caps, fixed facility costs and tiered lane rates
Scale record: 14 factories, 17 distribution centres, over 50 product groups and 32,000 retail sites (1,600 demand clusters) solved in about 10 s per scenario
Interfaces: The same stateless HTTPS API, plus the Excel add-in for consulting teams
