Ship Scheduling Problem Based On Multi-Time Berth Pricing

In recent years,the rapid development of global trade to promote the shipping industry more prosperous,the port berths and facilities and equipment to become scarce resources,the port in order to make full use of port resources,to avoid uneven distribution of time to the port.The port based on this change the original pricing mechanism,The company changed the pricing mechanism in the port without changing the original route under the premise of changing the liner timetable to minimize operating costs,so that the ship can be made more smooth distribution of time and can reduce the operating costs of shipping companies to achieve a win-win.Therefore,this paper attempts to combine the phased berth price with the lowest operating costs of the shipping company as a standard for future liner scheules,assuming that the port is priced at the time of the berth.However,through the empirical analysis,we can see that the current port-to-port time distribution is uneven,and the port is single to the shipping company.For the future development of the shipping industry,the common interests are realized.Based on the ship scheduling problem under the multi-time berthing pricing,Value of the research topic.This paper mainly studies the problem of ship scheduling based on multi-time parking pricing.Firstly,the theory of ship dispatching,the theory of schedule optimization,the theory of port optimization and the research on ship dispatching problems at home and abroad are analyzed.Based on the previous studies,the paper analyzes the distribution of ships to Hong Kong Based on the characteristics of the problem,the ship dispatching model based on the multi-time period parking pricing is established according to the characteristics of the ship scheduling problem under the multi-time parking pricing.And Maersk a cross-Pacific route as an example,call CPLEX to solve the model,and the results of the visualization of the show.Finally,the changes in the timetable under a variety of pricing mechanisms are analyzed.
