Trade off Optimization of Berth Scheduling in Container Terminal

To offset the negative effects caused by the reduction of operation time,a least-cost model including berthing location,berthing time and loading speed,which is more suitable for the berth scheduling in container terminal,is established.The arithmetic was designed by the combination of human-computer interaction and genetic algorithm and an example was given to verify the validity of the model and the feasibility of the solution method.The results show that equilibrium schedule can be obtained by adjusting values of berthing location,berthing time and loading speed in the objective function.And solutions are more satisfying when combining with the expert experience and the genetic algorithm.The method can solve the equilibrium optimization problem and the results are more proximate to the practical situation.
