The classic problem of vehicle route optimization is known as the Vehicle Routing Problem (VRP). The VRP is a mathematical optimization problem that aims to determine the most efficient routes for a fleet of vehicles to take in order to visit a set of customers or locations while minimizing the total distance or travel time.
The VRP is considered a "hard" problem, meaning that it is computationally difficult to find an exact solution in a reasonable amount of time. The problem involves determining optimal routes for multiple vehicles visiting a set of locations, typically with various constraints such as vehicle capacity, time windows, and delivery requirements.
Key Solution Strategies
- Exact Algorithms: These methods guarantee optimal solutions but are computationally expensive for large problem instances.
- Heuristic Methods: Fast approximation algorithms that provide good solutions in reasonable time.
- Metaheuristics: Advanced optimization techniques like genetic algorithms, simulated annealing, and ant colony optimization.
