Optimization Of The Path Of The Multimodal Network On The Base Of Transport Rationalization

Multimodal transport is to take into account the advantages of all modes of transport as well as the requirement of the integrated transport system, using cooperative relations various modes of transport, so that transportation costs and place utility to a minimum. The development of integrated transport system has brought greater opportunities to the development of multimodal transportation. And multimodal transportation will play an increasingly important role in the integrated transport system. In multimodal transportation, the route selection is of utmost important.On the basis of previous studies, thesis has further studies the route selection of multimodal transportation. Main research contents:(1)On the basis of introduction of the concept of multimodal transportation, thesis analyses the status quo of China's container transportation. Thesis puts forward the strategies China should adopt when developing multimodal transportation.( 2 ) In the context of integrated transport and sustainable development, multimodal transportation is given a special meaning of rationalization. On the premise of rationalization of multimodal transportation, thesis analyses the factors that affect the route selection of multimodal transport operators. Through establishing the evaluation index of the route selection in the rationalization of multimodal transportation, FAHP is adopted to determine the best route of multimodal transportation.(3)At last, based on the decision–making of multimodal transport operators, the thesis build a model of the reasonable route selection in the multimodal network. The model takes into account the transport distance, time, cost and transit times to find the reasonable path and improved genetic algorithm is adopted. Then the other model takes into account of multiple batches of goods, transportation economics of scale and genetic algorithm is adopted.
