| The shipping of Tianjin port mainly in bulk cargo,groceries and container transport,is a relatively large comprehensive port in northern China,the groceries transportation in Tianjin port has been occupying an important position.Tianjin port cargo transportation network construction determines the Tianjin port cargo transport efficiency,and further reflects the Tianjin port general cargo terminal strength,has the vital significance to the future of Tianjin port cargo transportation development.In recent years,with ports throughput of the Tianjin port increases gradually,Tianjin port opens up more new routes,so that cargo transportation route network chaos,the main performance is the route relatively unreasonable,the limited capacity of different schedule,route setting will have some overlap and liner service level is relatively low,it can not meet the needs of cargo transportation increasingly,a serious obstacle to development of general cargo export trade.Therefore,how to arrange the route network of Tianjin port cargo liner shipping market,improve efficiency,and reduce the operation cost of shipping company,has become an urgent problem to solve for Tianjin port.This paper mainly takes Tianjin port cargo transportation as the main research object,First of all,I have combed the research literature of scholars at home and abroad on the shipping network,applied to the related theories,including the characteristics of general cargo liner classification and schedule of the book and liner shipping network optimization theory research etc.Secondly,Tianjin port cargo wharf is analyzed in detail the present situation of the general cargo liner shipping network,has carried on the SWOT analysis to a cargo wharf,and analyzes the tianjin port Southeast Asia different schedule of break-bulk liner transport problems.Then according to different schedule of cargo transportation network overlap integration,I establish the optimization model of general cargo liner shipping network in order to minimize the total cost of operation of the Tianjin port,use genetic algorithm to solve the model.According to above analysis,puts forward the corresponding suggestions for the development of Tianjin port cargo transport. |
