Strategy and simulation on berth allocation based on distributed hybrid genetic algorithm

To the problem of berth allocation, a rolling-horizon approach is proposed. According to thisapproach, a dynamic allocation model is initially developed based on the integer programming for berth allocation, which is more closed to reality as the result of basing continuum quayside. At the same time,a simulation model is developed based on the berth allocation model, and a distributed hybrid genetic algorithm is employed for solving the model, which combines distributed hybrid genetic algorithm and heuristic algorithm. A case applying this approach on a certain container terminal shows the validity and usefulness of the model and algorithm.
