Coordinated Allocation Strategy Of Multiple Quay Berths With Considering Berth Depth

Due to the limited berth resources in the port,many terminal operators began to seek the integration of multiple terminal resources within the portin recent years,a carrier focus on the operation of multiple terminals in different areas of the port,in this way to enhance the overall competitiveness.In addition,at the actual container terminal,due to the limits of the design of the berth water depth and other physical conditionswhen the pier is designed,not all vessels can berth each dock,especially the large-scale container ships,and at the container terminal it is a ubiquitous phenomenon.Therefore,the allocation of berths for the ship must take into account the berths' water depth constraints,so as to enables the berth plan to adapt to the actual demand better.Based on the above background,the problem of continuous berth allocation is extended from a single terminal to a multi-terminal,taking into account that the berth water depth is different depending on the construction period of the wharf,so that the types of ships that can be docked are different.This paper take into account the draft requirements of the ship when the berth is allocated,first allocating the ship to the berth shoreline that meets its draft requirements,and then formulate the specific berth plan for each wharf shoreline.Based on the conditions considered,this article establishes a mathematical model to satisfy the coordinate distribution of multiple berths in the same port,and designs the heuristic algorithm to solve the problem.Finally,based on the actual data of the port,an example is given to validate the model and algorithm.The traditional berth allocation method and the multiple dock coordination allocation method are used to solve the generated examples.
