A Hybrid Ant Colony System for Vehicle Routing Problem with Time Windows
نویسندگان
چکیده
Vehicle Routing Problem with Time Windows (VRPTW) is a well known NP hard combinatorial scheduling optimization problem in which minimum number of routes have to be determined to serve all the customers within their specified time windows. Different analytic and heuristic approaches have been tried to solve such problems. The proposed hybrid algorithm uses ant colony system as well as random search incorporating simulated annealing concepts to solve VRPTW problem. From simulation results, it is shown that the proposed algorithm has satisfactory performance.
