Why it wins: Optimisation with measurable cost and emissions savings.

Build flow

01 · Problem
Small delivery fleets drive extra kilometres because routes are planned by hand.
02 · Solution
Solve a vehicle routing problem with time windows, estimate CO2 per vehicle type and compare savings against current routes.
03 · Build
  1. 1Import stops
  2. 2Solve routing with constraints
  3. 3Estimate emissions
  4. 4Visualise on a map
04 · Demo
Load 30 deliveries and compare the hand-planned and optimised routes on a map.
