Embodiment Construction

[0089] Hereinafter, in conjunction with the accompanying drawings, a preferred embodiment is described in detail to further illustrate the present invention.

[0090] Such as figure 1 As shown, first of all, the container terminal condition monitoring controller provides an optimized dispatching plan. Then after a period of time, the state monitoring controller measures the state of the equipment, namely the actual position and the actual speed. These status measurements are used to update the minimum completion time required for upcoming tasks. Then update the time of a task for the condition monitoring controller. The condition monitoring controller then determines a new scheduling plan for the interacting devices. When the loading and unloading equipment is disturbed, the present invention provides a method for rescheduling the loading and unloading equipment of an automated container terminal, which includes the following steps: Step 1: Three-stage equipment model step; St...

Abstract

The invention discloses a rescheduling method for automatic container terminal handling equipment. The method comprises the steps of S1, establishing models of devices in three stages; S2, determining scheduling states of the devices in the three stages; S3, determining rescheduling of the devices in the three stages. A state monitoring controller of a container terminal provides scheduling schemes for optimizing the devices in the three stages; after a time period, the state monitoring controller measures actual positions and actual speeds of the devices in the three stages; the minimum completion time required for a to-be-performed task is updated according to state measurement values of the actual positions and the actual speeds; the state monitoring controller monitors updated task time according to the minimum completion time required for the to-be-performed task; and the state monitoring controller determines new scheduling schemes for the devices in the three interacted stages. The method has the advantage of providing rapid and accurate rescheduling schemes under the condition that the handling equipment is interfered.

Description

Technical field [0001] The invention relates to the field of container transportation, in particular to a re-dispatch method of automated container terminal loading and unloading equipment. Background technique [0002] In the past few decades, more than 60% of global deep-sea cargo was transported in containers. Cargo transportation management needs to adapt to the growing demand of containers. Combined transportation is flexible and expandable, and different transportation methods can cover different areas for different transportation distances. A container terminal that can be intermodal generally includes several modes of transportation: barge, train and truck. Therefore, container terminals play a vital role in cargo transportation. [0003] Due to its highly dynamic and complex environment, the optimization of container terminal scheduling is highly concerned by many researchers. The scheduling problem is an optimization problem, which is to allocate a series of tasks to ...
