The vehicle routing problem (VRP) has been extensively studied because of the interest in its application in logistics and supply chain management. In this paper, we develop a hybrid algorithm (IACS-SA) that combines the strengths of improved ant colony system (IACS) and simulated annealing (SA) algorithm. The results of computational experiments on fourteen VRP benchmark problems show that our IACS-SA produces better solutions than those of other ACS in the literature. The results also indicate that such a hybrid algorithm is comparable with other meta-heuristic algorithms.
