Delivery planning and route optimization are vital for streamlining transport, labor and logistics costs in the era of free delivery and rising gas prices.
So called "last mile" deliveries can consume up to 30% of the entire supply chain cost so it's a prime candidate for optimization.
It's not without challenges. Even relatively simple route optimizations can be extremely complicated. Computers have a very difficult time trying to calculate efficient routes even for extremely short routes with simple delivery requirements.
