Hereinafter, a method of adjusting the schedule of the equipment in the container terminal according to the present invention through the system configured as described above will be described with reference to FIGS. 2 to 4 and FIGS. 5 to 7 described later.

FIG. 5 is a flowchart showing a method of adjusting the schedule of equipment in a container terminal according to the present invention, FIG. 6 is an exemplary view after receiving job schedule information applied to the present invention, FIG. 7 is a flowchart of a job schedule information As shown in FIG.

First, the terminal operation server 200 transmits a plurality of pieces of equipment such as a quay crane (QC), a yard truck (YT), a yard crane (YC) and a terminal access gate (GT) 110, the operation time of each device, the work location, and the work time (S310).

As shown in FIG. 6, the information input unit 210 may receive job schedule information from a terminal installed in each of the devices 110, and may input the job schedule information through the input screen shown in FIG. A log of the plan plan including the operational plan of each equipment (110), the integrated statistical plan required for the quantitative operation of each equipment, and the ship work plan for the vessel, resource plan for each equipment and gate operation plan Data can also be received from the administrator.

Next, the terminal operation server 200 transmits operation plan data for each of the devices 110 input through the information input unit 210, statistical data including information generated during quantitative work of each device, And the plan data including information on a ship operation plan and an equipment input plan required for the entire subcontracting work performed in the database 220 (S320).

At this time, the terminal operation server 200 reads the equipment operation data, the statistical data and the plan data from the database 220 through the data loader unit 230, ) Constitute cache information so that the equipment operation data, statistical data and plan data can be read out at high speed.

Next, the terminal operation server 200 calculates the time required for each of the devices 110 to move and work through the predetermined position through the management function module 250 (S330).
4 (a)) and a second yard truck (second YT) (see Fig. 4 (a)), as shown in Figs. 4 4C shows the "Pre-schedule Gantt Chart for Each Equipment" (see FIG. 6), in contrast to the schedule representing the time required to transport the 11th container to the 17th container, The first quay crane (first QC) is a schedule showing the time required for uninterrupted shipment of the eleventh container to the seventeenth container. In FIG. 4A, " 11 (S-1) "indicates the time required for the first yard truck to transport the eleventh container," 13 And the gray space between them indicates the time required to move to the tolerance (in this specification, the scheduling is not considered in this specification). Similarly, "12 (S-1)" in FIG. 4 (b) represents the time required for the second yard truck to carry the 12th container, and "15 It represents the time it takes for the truck to transport, and the gray space between them represents the time it takes to travel by tolerance. Similarly, "11 (S)" in Fig. 4C represents the time required for the first quay crane to load (or unload) the eleventh container, and "12 1 It represents the time required for the crane crane to load (or unload), and the gray space between the crane crane and the crane represents the time required for the crane spreader to move to the tolerance.

Thereafter, the terminal operation server 200 determines whether a job delay (not a work delay occurring when an operation is performed in an actual container terminal) is performed through the management function module 250 when performing a job schedule of each of the devices 110 In other words, it is determined whether a job delay occurs in performing the job schedule (S340).

If it is determined in step S340 that a task delay occurs in the task schedule of each of the devices 110, the terminal operation server 200 may generate a task schedule through the management function module 250 The operation schedule of each of the devices 110 is adjusted in consideration of the occurrence delay time and the occurrence time and the duration time of each device 110 in operation S350.
In the above example, if scheduling is performed when each yard truck and quay crane start work as shown in FIG. 4, the eleventh container and the twelfth container are respectively set to the first and second There is no problem with the yard truck being completed (see x1 and x2 in FIG. 4), but in the case of the 13th and 15th containers, the first yard truck did not complete the transportation (See y1 and y2 in Fig. 4). Therefore, the management function module 25 must force the operation time of the first quay crane at the time point 13 (S-1) when the first yard truck completes the transportation of the thirteenth container (Fig. 4 (Yellow portion) of " Y " is generated as shown in Fig. 4 (d). As a result, it is necessary to tune the schedule of the first quay crane to determine the schedule as shown in FIG. 4 (c), which is indicated by the red part in FIGS. 4 (d) and 4 (e). Meanwhile, as a result of adjusting the schedule for the thirteenth container, since the operation of the first crane crane is delayed by 'Y', the operation delay problem of the fifteenth container is automatically resolved. Thus, it is repeatedly performed for each time zone, and when all is completed, the scheduling is ended. The adjusted work schedule can be found in the "Schedule Gantt Chart for Each QC Equipment" in FIG.

That is, according to the statistics and the plan information according to the job schedules of the respective devices 110, the terminal operating server 200 may notify the terminal of the operation delay (in the scheduling process, not the operation delay generated as a result of performing the actual operation of each device) The schedule for each task 110 is predicted and the task schedule is adjusted according to the task delay time or the schedule is adjusted so that the task can be performed by inputting other equipment.

Next, the terminal operation server 200 determines, based on the work schedule of each of the devices 110 read through the management function module 250, The schedule for the carry-in and carry-in plans is adjusted (S360). However, this process is intertwined with the situation outside the terminal, so the server can not arbitrarily adjust it.

The terminal operation server 200 then outputs the job schedule data of each of the devices 110 transmitted from the management function module 250 through the display unit 260 to the information input unit 210 to coordinate the operation time and the operation order of the equipment (S370).

At the same time, the terminal operation server 200 transmits the job schedule data confirmed by the management function module 250 to the respective devices (QC, YC, YT and GT) through the signal transfer unit 270, So that it can be operated according to the job schedule (S380).

Therefore, according to the present invention, it is possible to perform job scheduling for each device in the container terminal based on various physical object information in the container terminal, operation statistical information to which the operation delay time of each device is applied, It is possible to complete all the tasks in the planned time and to adjust the schedule according to the predicted work delay time so as to shorten the working time of each equipment during actual work and optimally improve the utilization of each equipment.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, Of course.
