Description

External expert system linkage device and method {EXTERNAL EXPERT SYSTEM LINKAGE DEVICE AND METHOD}

The present invention relates to terminal operation technology, and more specifically, to an outsourced expert system linkage device and method for optimizing ship terminal operation by linking an external expert system to overcome the performance limitations of the optimization algorithm for ship terminal operation. .

Container terminals play the role of unloading and loading containers, storing containers, and importing and exporting containers from outside. For example, in a container terminal, quay cranes (QC) are placed at the location where the ship docks, and multiple yard cranes (Yard Crane (YC)) are installed at the yard block (yb) where containers to be unloaded and unloaded are loaded. ), container unloading and unloading operations from the ship are performed by the quay crane (QC), and container handling operations at the yard block (yb) are performed by the yard crane (YC) and are transported to the yard truck (Yard Truck). : It is configured to be transported through YT).

In general, the container terminal operation system used in port logistics inevitably has performance limitations due to external environmental factors, no matter how optimized the operation plan algorithm is applied. To overcome these limitations, some parts, such as the shipping plan of the ship's terminal operation system, still rely on the personal capabilities of external experts such as planners or external expert systems. Planners with different standards and different work methods establish loading plans based on their own experiences, so it is difficult to create efficient loading work plans when operating a ship due to differences in capabilities or insufficient information.
