| Research Abstract |
In this research, we presented a solution to real-world delivery problems for home delivery services where a large number of roads exist in cities and the traffic on the roads rapidly changes with time. The methodology for finding the shortest-travel-time tour includes a hybrid meta-heuristic that combines ant colony optimization (ACO) with Dijkstra algorithm, a search technique that uses both real-time traffic and predicted traffic, and a way to use a real-world road map and measured traffic in Japan. We proposed a hybrid ACO for RWDPs that used a MAX-MIN Ant System (MMAS) and proposed a method to improve the search rate of MMAS. Since traffic on roads changes with time, the search rate is important in RWDPs. Experimental results using a map of central Tokyo and historical traffic data indicate that the proposed method can find a better solution than conventional methods.
