Research on Representation Model and Algorithm of Freight Carrying Capacity in Middle Reaches of Yangtze River

Xiangchen Wang

Abstract


Essentials Freight Carrying Capacity of Middle Reaches of Yangtze River is Data Base of Shipping Development Planning.Connecting segments of different sizes in the middle reaches of the Yangtze river to form a multi-stage waterway,taking the cargo flow between any port of departure and the port of destination as a variable,the maximum sum of cargo flow as an objective function ,taking the cargo network, OD matrix and the capacity of each segment as limiting conditions ,using the maximum value of the objective function to characterize the cargo carrying capacity of the middle reaches of the Yangtze river waterway .Applying Complex Network Theory and Method,Combining Port Throughput Data, Calculating Freight Network, OD and Matrix;Applying Ship Following Theory ,Combining Ship Domain Parameters, Calculating Passage Capacity of Each Segment.The research results show that,has a freight carrying capacity of 68 in the middle reaches of the Yangtze River8 billion and T,Among them, the freight carrying capacity of the downstream channel in the middle reaches of the Yangtze River 36.9 billion and T,Restricted leg to Yue yang-Wuhan leg, Freight,Restricted leg to Huangshi-Jiujiang leg.
