Reward-Density Heuristic for Dynamic Multi-Vehicle Routing: Performance and Computational Efficiency
Summary
A new reward-density heuristic, termed the Efficiency heuristic, addresses a dynamic, online multi-vehicle routing problem combining elements of the Vehicle Routing Problem (VRP) and the Orienteering Problem (OP). This heuristic aims to maximize cumulative reward within a fixed time horizon, with continuous replanning for new tasks. Evaluated across autonomous drone task allocation and urban taxi dispatch, the Efficiency heuristic was compared against four classical construction heuristics and three metaheuristic algorithms (Adaptive Large Neighbourhood Search, Genetic Algorithm, Simulated Annealing). It consistently matched the solution quality of the best metaheuristics while requiring two to three orders of magnitude less planning time, establishing Pareto dominance on the reward-versus-compute frontier across all tested configurations.
Key takeaway
For AI Engineers developing real-time allocation and dispatch systems, consider evaluating the Efficiency heuristic. This approach offers superior computational efficiency, requiring two to three orders of magnitude less planning time, while matching the solution quality of complex metaheuristics. Its Pareto dominance makes it highly suitable for dynamic, time-constrained environments like autonomous drone operations or urban taxi services, enabling robust online deployment.
