In the process of transformation from the traditional handling service to the comprehensive logistics service of the modern coal port,port overall scheduling requires more intelligent and efficient,so the coal port of joint scheduling optimization needs to be solved by the system theory.To counter the key problems affecting unloading scheduling,considering traffic concentration reached,train scheduling factors such as restriction,on the basis of modern coal port production process,focusing on the unloading joint scheduling optimization of modern coal ports,we build the model for the shortest waiting time,the shortest operation time,and the shortest dynamic operation time associated yard operation (the train-car dumper-yard joint scheduling optimization model).Using corresponding optimization strategy,we analyze the optimization model and realize the optimal intelligent unloading scheduling of each link.
