Multi-target one-way channel wharf continuous berth allocation scheduling method

Abstract

The invention relates to a multi-target one-way channel wharf continuous berth allocation scheduling method. According to the method, a ship entering and leaving problem is abstracted into a two-dimensional encasement model, a hybrid algorithm is designed for solving with the maximum port effective berth utilization rate and the minimum port effective berth utilization rate as comprehensive targets, and ship entering and leaving conditions and loading and unloading cost factors are fully considered and include that ships with large load tons need to enter and leave a port within a tidal time range; ships incapable of navigating at night need to enter and leave the port before sunset or after sunrise; the shoreline function of the berthing position of the berthed ship should be matched withthe requirements of ship goods types and the like; goods berthed on each section of shoreline have different loading and unloading costs when arriving at each reservoir area. According to the method,the port ship entering and leaving time and the berthing position are automatically arranged, berth resources can be fully utilized, the cost is saved, and the port operation efficiency is improved.

Description

technical field [0001] This patent application belongs to the technical field of port dispatching, and more specifically, relates to a continuous berth allocation and dispatching method for a multi-objective one-way channel wharf aiming at maximizing the effective berth utilization rate of the wharf and minimizing the port cost. Background technique [0002] In recent years, large hub ports along the coast of my country have been keenly aware of the trend of internationalization, intelligence, and green development of global ports, especially in the planning and construction of smart ports, and have accelerated their pace. Due to problems such as early planning and capital investment, it is difficult to improve basic port resources such as waterways and berths in a short period of time. Therefore, a scientific and reasonable arrangement of ship berthing and berthing plans can effectively solve the phenomenon of ship pressure and port pressure. In addition, the storage positi...

Problems solved by technology

With the expansion of the port scale and the increase in the number of ships entering and leaving the port, only focusing on a single goal and artificially arranging the plan based on experience can no longer meet the needs of port development.
