摘要:AbstractCurrently, road transportation is still the main part of China's automotive logistics. Railway and waterway traffic are increasing in recent years, but are still small in the proportion of China's automotive logistics. Therefore, the automotive logistics of multimodal transportation and the distribution of the mode of transport are paid more and more attention. This paper focuses on the transport allocation problem of the commodity car. When the route and demand are fixed, considering the transportation cost, transportation time and the mode of transportation capacity constraints, establish a model to solve the road, railway and waterway transportation allocation problem. And design a genetic algorithm to solve the mode of transportation allocation problem to minimize the logistics cost. Finally, a case study is given to verify it.
