Container terminal yard bridge busy and idle state assessment method and entering container truck operation queue intelligent dispatching method using method

Abstract

The invention relates to a container terminal yard bridge busy and idle state assessment method and an entering container truck operation queue intelligent dispatching method using the method. The assessment method comprises the steps that 1) standard operation instructions are set; 2) the number of the standard operation instructions required by movement of a yard bridge from the present position to a target yard position is calculated in a conversion way by using a formula; and 3) the busy and idle state of the yard bridge is assessed. The dispatching method comprises the steps that (1) a yard bridge operation partitioning plan is formulated and general parameters are set; (2) container trucks enter and the problem of the container trucks is judged; (3) whether the container trucks of a buffer area are saturated is judged; (4) existence of the container trucks entering the same working area in the buffer area is judged; (5) existence of the yard bridge in the working area is judged; (5.1) the process turns to buffer queuing dispatching if the judgment result is no; (5.2) the number of yard bridge standard operation instructions is calculated in the conversion way if the judgment result is yes, and the busy and idle state is judged; (5.2.1) if the busy and idle state indicates saturation, the container trucks turn to buffer queuing dispatching; (5.2.2) if the busy and idle state indicates the idle state, the container trucks enter the target yard position; and (5.2.3) if the busy and idle state indicates the busy state, a brake block rod is lifted after delay time T2.

Description

technical field [0001] The invention relates to the field of dispatching and controlling field of collection truck entry at a port container terminal, in particular to a method for evaluating the busy / idle status of yard bridges at container terminals and an intelligent scheduling method for operation queues of collection trucks entering the gate using the method. Background technique [0002] In the loading and unloading operation of the container terminal in the whole port, the distribution operation order of the truck entering the gate plays a vital role. When the collection truck arrives at the terminal, it first needs to obtain the permission to enter the yard at the gate of the terminal, then pass through the gate to the target yard, and wait for the yard bridge to pick up or unload the boxes. The passing capacity of the gate and the passing time of bicycles both affect the customer's evaluation of the terminal service, and at the same time affect the operating efficie...

AI Technical Summary

Problems solved by technology

[0004] However, in the loading and unloading operations of the existing container terminals, there are still problems in the scheduling of the entry truck operation queue, which is reflected in the following: the terminal collection truck entry method is regardless of whether there is an operation yard bridge in the yard operation area or whether it has exceeded the operation yard bridge The operating capacity is all given the operating position, resulting in congestion in the yard and the inoperability of the operating yard bridge, which affects the overall efficiency of loading and unloading operations

In addition, the queuing and arrangement of collection trucks are all arranged manually. The unbalanced and unreasonable operations of the yard and bridge due to the differences in the overall control of the personnel also directly affect the efficiency of the yard and bridge operations.

[0005] In recent years, with the development of national port container terminals and the improvement of informatization, in order to reduce the input of manpower and material resources, improve the effect of land transportation management and control, and reduce operating costs, there has been a practice of setting up buffer zones in container terminals for diversion, but the defect is that All collection trucks enter the buffer zone for diversion, and the method of real-time allocation of yard bridges by management personnel according to the situation in the yard is still adopted. As a result, collection trucks that do not need to enter the buffer zone have to enter the buffer zone to get tickets, and the number of truck drivers increases. At the same time, due to manual operation, it is difficult to realize real-time tracking of the on-site operation bridge tasks, it is difficult to find the best position in real time, and it is impossible to realize scientific and accurate deployment, which also causes a decline in the utilization rate of the yard bridge and affects the wharf pile. The efficiency of the overall loading and unloading operation of the yard, waste of energy and human resources
