Abstract: Aiming at transport route optimization problems during the wartime, ?the risk coefficient assessment model and the multi-objective optimization model are put forward for assessing the risk of carriage reasonably and selecting optimal transport route efficiently. As transport network accords with complex network characteristics, the importance of the transport network nodes is analyzed, based on the complex network, combining with the impact of the distance between the battlefields, the risk coefficient assessment model of transport network nodes is established. In the meanwhile, the concept of the risk time is put forward to measure the value at risk of the route, based on nodes risk coefficient and the route running time, and then experts decide the comprehensive weight of transportation time and risk time, to establish the multi-objective optimization model of the transport route. Finally, optimized Dijkstra algorithm is used to optimize transport route. According to the experimental simulation analysis, the method is feasible on transport route optimization problem during the wartime.
