Feeder Hub-and-spoke Shipping Network Design With Foreign Trade Containers

The thesis first analyzes the shaft radial general research situation of container shipping network, found few academic from the Angle of axial radial container transfer in-depth discussion; Then review the container routes influence factors and design, points out the existing problem is mainly for container storage constraint, time window constraint set was lacking, etc.; Regional optimization and lightering operation are discussed, and points out that the urgency of the pearl river delta foreign trade container feeder transportation research, to draw lessons from the VRP or TSP model applied in shipping documents. In practical research, straighten out the import and export container of waterway transportation process, as well as the typical representative of shaft radial network- port group of transportation system and jianghai transport system, and extract the foreign trade container water transfer involved in all aspects. Then analyzes the present situation of the application of the pearl river delta ports group of public barge transportation platform, which provides the basis for building the barge route optimization model.Based on previous studies, the paper finally puts forward the foreign trade container transfer routes based on the axial radial network planning model. To solve the problem of NPH solving complexity of the model, then refer to the current popular heuristic algorithms, improved genetic algorithm was designed, then, the Matlab was used to implement code, through the guangzhou port group "shuttle bus" skill survey data as input and related processing model, to test paper model and solving the feasibility and effectiveness of the algorithm. Finally, return to practical problems, namely the different mode of transfer decision-making service network, in this paper, based on the results of data analysis, quantitatively discusses the implementation of optimized transfer routes advantages and risks, and to support the new transfer network policy recommendations.Results show that this paper puts forward that the transfer of route optimization model, the waterway transportation in port group of system application scenarios in generality, designed by genetic algorithm, GA can effectively solve the model and convergence. Nansha "shuttle bus" platform with data as input, according to the solution of the model and the feasibility of the algorithm through the inspection, the existing regional port of import and export demand the same circumstances, the guangzhou port group to optimize the routes, but instead by 7 "optimization services network" covered by a barge can navigate barge fixed cost, variable cost, the respect such as port cost, total cost respectively 63.2%, 48.2%, 31.6% and 26.6% of savings, rose by an average of 41 TEU loading capacity, and one-way flight density increased by 57.9%, the effective to alleviate the phenomenon of "empty to empty return" at the same time, to the shipper to provide a higher degree of convenience. Way under the new transfer network, on the other hand, each barge "average service time" will extend the 4.4 hours, and port handling fee for a higher proportion problems, need scheduling efficiency through ascension, ports and cooperation, increase the proprietary ship, strengthening the alliance cooperation, support the development of the "transfer to optimize routes".
