Perishable Supply Chain: Spoilage & Transit Simulator (2D)

This 2D top-down companion visualizes the identical exponential spoilage model as the 3D simulator, using a route map of farms, a distribution hub, and stores instead of an orbiting 3D scene. A fleet of shipments moves fresh produce from farms through the hub to stores, and every crate's freshness decays according to Q(t) = 100·e^(−kTt), driven by refrigeration temperature and elapsed transit time. Switch between truck, train, and drone transport to trade off route speed against per-trip capacity, drag the temperature and distance sliders to see how quickly the exponential curve erodes quality, and watch live readouts for average fleet freshness, spoilage loss rate, delivered shipment count, and net revenue after waste. Drag to pan the map and scroll to zoom in on any leg of the route.
