Cooperative Optimization for Port and Shipping Line with Unpredictable Disturbance Consideration

As the container shipping which is a complex logistics system is affected by a variety of unpredictable disturbances, a cooperative optimization model of berth and speed is proposed to realize the coordination between port and shipping line. Regarding the total port time of vessels as the objective, a discrete berth allocation model is established. Based on a nonlinear relationship between fuel consumption and speed, a speed optimization model for the vessel is also established, and the fuel consumption during the port time is introduced to improve it. To integrate the berth allocation and the speed optimization, a dynamic negotiation mechanism for port and vessels based on the speed is designed. The simulation experiments verify that the coordination proposed can reduce both the influence of disturbance and the fuel consumption.
