Hereinafter, a workflow management method of a plurality of equipment in a container terminal made through the system of the second prior art described above will be described with reference to FIGS. 3 to 7 described above.

6 is a flowchart illustrating a method for managing a workflow of a plurality of equipment in a container terminal according to the second prior art, and FIG. 7 is a view showing a subroutine for designing a main ship work planning program applied to the second prior art.

First, the terminal operation server 200 receives the container loading and unloading operation information including the berthing position of the vessel, the container type and attribute, and the scheduled operation time information, from the ship terminal and the ship terminal provided in the plurality of ships (S310) .

Next, the terminal operation server 200 stores the plurality of loading and unloading operation information received in step S310 in the database 220 (S320).

Then, the terminal operation server 200 is based on the container loading and unloading operation information received from a plurality of ship terminals through the steps S310 and S320, after designing the onboard operation plan program 240, the database 220 is stored in (S330).

At this time, in the step S330, the main line work planning program is designed according to the subroutine as shown in FIG. 7, and steps S3301 to S3310 to be described later may be selectively performed as needed regardless of the order.

First, the terminal operation server 200 is transmitted from a plurality of ship terminals through the mothership berthing plan inquiry module 240a, and according to the loading and unloading operation information stored in the database 220, the mothership berthing location, container type and properties, and work schedule It enables the user to inquire the mothership berthing plan including time information and the like (S3301).

Next, the terminal operation server 200 receives information on the number of quay cranes assigned to each ship or idle information according to the mother ship berthing plan inquired in step S3301 through the quay crane (QC) information collection module 240b. to be collected (S3302).

Then, the terminal operation server 200 aligns the quay wall crane according to the expected berthing time of the berthing vessel through the alignment module 240c, aligns the berthing position according to the berthing vessel, and at the time of loading and unloading for each bus. It is possible to arrange the starting time of the operation (S3303).

Then, the terminal operation server 200 generates a schedule box for the loading and unloading workflow based on the time and location information corresponding to the bus berthing plan according to the execution of step S3303 through the schedule box generating module 240d. to make it possible (S3304).

Next, the terminal operation server 200 searches for a plurality of bus information through the berthing plan inquiry screen formed in the schedule box created in step S3304 through the bus information search and selection module 240e, The comparison target bus information can be selected (S3305).

Then, the terminal operation server 200 enables the creation of the work list in the order of the work flow according to the comparison target bus information selected in step S3305 through the work list generation module 240f (S3306).

Thereafter, the terminal operation server 200 calculates the working time according to the unloading and loading of each container through a combination of the properties of the container and the productivity of the quay crane through the working time calculation module 240g (S3307) .

Next, the terminal operation server 200 allows to calculate the quantity of loading and unloading allocated to the quay crane and the yard truck for each mothership container in units of time through the loading and unloading quantity calculation module 240h (S3308).

Next, the terminal operation server 200 generates and displays the work schedule of the quay crane assigned to each container through the quay crane (QC) schedule screen generation module 240i (S3309).

In addition, the terminal operation server 200 calculates the container loading ratio for the same time period through the double cycling expected ratio calculation module 240j and enables the double cycling occurrence ratio to be displayed through a graph (S3310).

On the other hand, after the step S330, the terminal operation server 200 selects the bus ships of the main ship work planning target for the loading and unloading through the on-board work planning program 240 designed through the step S330, and stores the information on the loading and unloading of the selected bus in the database. Inquire from 220 (S340).

Next, the terminal operation server 200 establishes a loading and unloading work plan for a plurality of bus ships through the main line work planning program 240, and stores the established results in the database 220 (S350).

Then, the terminal operation server 200 displays information on a plurality of ships in which the loading and unloading operation plan is established through the display unit 260, and establishes a loading and unloading operation plan according to the operation of the input unit 210 by the manager. A selection signal for a plurality of comparison target vessels to be compared is received (S360).

Thereafter, the terminal operation server 200 inquires from the database 200 for a plan of loading and unloading for the target vessel selected through the step S360 (S370).

Next, the terminal operation server 200 displays the onboard operation plan information for each time period for the comparison target vessel selected through the onboard operation planning program 240, the unloading and loading quantity ratio, and the double cycling possible expected ratio information on the display unit 260 ) through the display (S380).

At the same time, the terminal operation server 200 transmits information on the expected rate of occurrence of double cycling for the comparison target vessel selected in step S380 through the signal transmission unit 250 according to the loading and unloading operation plan. By transmitting to (QC), yard crane (YC) and yard truck (YT), respectively, as shown in FIG. 5 , the tolerance mileage of the yard truck is minimized and the utilization rate according to the quantity and unloading sequence information of the container to be worked It is possible to increase the probability of occurrence of double cycling that can maximize (S390).

According to this second prior art, through the main ship work plan, a plurality of quay cranes (QC), yard cranes (YC) and yard trucks (YT) arranged in the container terminal to simultaneously perform the loading and unloading work and At the same time, by ensuring that the proportion of the loading and unloading operations is not concentrated on specific equipment, it is possible to increase the probability of occurrence of double cycling, which can maximize the utilization rate while minimizing the tolerance mileage of the yard truck.

In addition, it has the advantage of being able to easily search for an adjustable target after the planner for each bus establishes the on-board work plan and compares it with the on-board plans of other bus ships. It can be designed in consideration of the situation that can increase the occurrence of double cycling by ensuring that the unloading and unloading of cranes exist in the same time period at the time of planning the ship.

On the other hand, as shown in FIG. 8, when the loading and unloading operation is performed on a plurality of busbars at the same time, and the unloading operation and the loading operation are simultaneously performed by a plurality of quay cranes in each busbar, the yard truck Operation requires a more complex dispatch system, and in this case, it is common to divide quay cranes and yard trucks into groups.

For example, as shown in Fig. 8, the first yard truck (QC1), the second quay crane (QC2) and the third quay crane (QC3) assigned to pool A ( YT1) to 6th yard trucks (YT6) are dispatched, and 7th yard trucks (YT7) to 10th for the 4th quay crane (QC4) and the 5th quay crane (QC5) assigned to group B (pool B) A yard truck (YT10) is dispatched to perform quantitative loading and unloading of containers on ships.

However, the general group assignment for the quay wall crane (QC) and the yard truck (YT) as above is due to the delay in dispatch of the yard truck (YT) according to the workload and the working time of the quay wall crane (QC). ) and the yard truck (YT), there is an inefficiency problem, such as increasing the time and cost required for the loading and unloading of containers as the work wait or work delay occurs.

Therefore, among the equipment used in the container terminal, in particular, it is essential to develop a system for a loading and unloading plan that can efficiently operate a quay wall crane (QC) and a yard truck (YT). With reference to this, it demonstrates as a 3rd prior art.

That is, in the third prior art, the tasks of a predetermined quay crane (QC) and a yard truck (YT) used for the loading and unloading of containers in the container terminal are assigned redundantly, and the To provide a system for redundant allocation of equipment in a container terminal to save time and cost, to flexibly operate the dispatch of a yard truck (YT) to a quay crane (QC) assigned a plurality in the container terminal, The yard truck (YT) dispatched to the quay wall crane (QC) is mutually designated, and a predetermined yard truck (YT) is dispatched at the required place and time according to the loading and unloading speed of the individual quay wall crane (QC).

8 is a view showing an example of the operation made through the redundant allocation system of equipment in the container terminal according to the third prior art.

That is, a plurality of quay cranes (QC) and a plurality of yard trucks (YT) are assigned to group A (pool A), and a plurality of quay cranes (QC) and a plurality of yard trucks (YT) are assigned to group B (pool B). ) is assigned, for example, if the third quay wall crane (QC3) of group A (pool A) is on standby for work, the user sends the work standby information through the terminal on the third quay wall crane (QC3) side to the equipment operation server Send to 200.

Then, the equipment operation server 200 corrects the loading and unloading plan according to the work waiting information received through the third quay crane (QC3) side terminal, and at the same time, sends the third quay wall crane (QC3) side terminal B ( By transmitting a signal that allows the work to be performed redundantly in pool B), the third quay crane (QC3) is assigned to work in duplicate in group A (pool A) and group B (pool B), The yard truck YT dispatched to the pool A and pool B may also be redundantly dispatched to the third quay wall crane QC3.

For example, the loading plan information for the third quay wall crane QC3 that is duplicately assigned to the pool A and pool B is as shown in FIG. 9 .

That is, by redundantly assigning the third quay crane (QC3) on standby for work, the first quay crane (QC1) and the second quay crane (QC2) assigned to group A (pool A) for the first yard truck (YT1) ) to the sixth yard truck (YT6) to be dispatched, and for the fourth quay crane (QC4) and the fifth quay crane (QC5) assigned to group B (pool B), the seventh yard truck (YT7) to 10th The yard truck YT10 may be dispatched, and all of the first yard truck YT1 to the tenth yard truck YT10 may be dispatched to the third quay crane QC3 that is overlapped.

Although the above prior arts have their own characteristics, nevertheless, when setting up a dispatch strategy, in both the first prior art to the third prior art, the dispatch strategy of the global setting is comprehensively applied to all yard truck pools. Since it is operated for dispatch truck dispatch (see Fig. 10), it is suitable for some yard truck pools, but not suitable for other yard truck pools. In this case, it may be an evaluation that is not realistically appropriate, and thus may not be effective.

Yard Truck Pool (Yard Truck Pool) is a similar meaning to Resource Pool, and is a group of equipment consisting of N yard trucks.

The tolerance movement distance is the distance that the yard truck must move from the current position (or the completion position of the last transfer operation) to the position of the target container for loading operation.

The arrival request time is a reference time at which the arrival (loading position) of the yard truck is requested in performing the indicated work.

Discharging refers to the operation of unloading a container loaded on a ship and loading it into the yard, and it refers to the operation of loading the container loaded into the yard onto the ship.

Remarshalling refers to the operation of moving containers installed in the yard to another location in the yard to secure space and prepare for ship work in advance.

As an evaluation criterion for optimizing the yard truck dispatch in the present invention, there is a minimization of an empty travel distance or a minimization of arrival delay (or waiting) time.

In addition, according to the evaluation criteria set by the user above, the system allows the user to inquire and analyze the result of dispatching the yard truck to help set the evaluation criteria later.

Now, with reference to FIGS. 15 and 16 , an evaluation method of a combination according to a set dispatch strategy will be described.

The definitions of various parameters related to the set value of the dispatch strategy are as follows.

R _S : weight for arrival delay (or wait) (0.0~1.0)

R _D : Weight for tolerance movement distance (0.0~1.0)

At this time, R _S + R _D = 1.0.

W _N : General importance for arrival delay (or waiting) (1-5)

W _H : Urgent importance for arrival delay (or waiting) (1~5)

T _TH : Threshold value of emergency task judgment criterion (sec)

AT _L : Allowable time for arrival delay (seconds)

AT _E : Allowable waiting time for arrival (seconds)

ET _Arrival : Estimated arrival time

ET _L : Estimated arrival delay time

P _S : Evaluation result for arrival delay (penalty points)

P _D : Evaluation result for tolerance travel distance (penalty points)

P _T : Total evaluation result (penalty points)

First, an evaluation method of a combination set according to a diversified dispatch strategy of a plurality of transportation equipment in a container terminal according to the present invention will be described with reference to FIG. 15 .

Calculate the expected arrival delay time ET _L (= RT _Arrival - ET _Arrival ) obtained by subtracting the expected arrival time (ET _Arrival ) from the arrival request time (RT _Arrival ) (S1401), _{and check whether ET L} is 0 or less ( S1402), if less than 0 (if it is determined that the yard truck arrives later than the expected time), the arrival delay allowable time (AT _L ) is positive again, and the expected arrival delay time (ET _L ) is the arrival delay allowable time (AT _L ) It is determined whether it is smaller than (S1403). If the determination result of step S1403, 'Yes', rating penalty for the arrival delay (P _S) is zero (= 0) (S1404).

On the other hand, if the determination result of step S1403 is 'No', it is determined whether the expected arrival delay time (ET _{L ) is greater than the threshold value (T TH} ) of the preset emergency work determination criterion (S1405), rating penalty (P _S) to get the evaluation penalty (P _S) for the arrival delay set by the product, and (S1406), otherwise the expected arrival delay time (ET _L) and the emergency priority (W _H) of the arrival delay expected It is set as the product of the delay time (ET _L ) and the general importance (W _{N ) for the arrival delay (S1407).}

On the other hand, if the determination result of step S1402 is 'No' (if it is determined that the yard truck has arrived earlier than the expected time), the allowable arrival waiting time (AT _E ) is positive and the expected arrival delay time (ET _L ) is the arrival It is determined whether it is less than the allowable waiting time (AT _{E ) (S1408).} If the determination result of step S1408, 'Yes', is also a demerit rating (P _S) is zero (= 0) for the delayed arrival (S1409).

On the other hand, if the determination result of step S1408 is 'No', similarly to steps S1405 to S1407 described above, it is determined whether the expected arrival delay time (ET _L ) is greater than _{the threshold value (T TH} ) of the preset emergency work determination criterion. (S1405), rating penalty (P _S) to set as the product, and (S1406) of the expected arrival delay time (ET _L) and the emergency priority (W _H) of the arrival delay for a large arrival delay, if not for the arrival delay rating penalty sets (P _S) as the product of general importance (W _N) of the expected arrival delay time (ET _L) and a destination delay (S1407).

The corresponding program coding is shown in Table 1 below.

Step 1. Arrival delay (or waiting) evaluation formula
ET _L = RT _Arrival - ET _Arrival
if (ET _L <= 0) // truck arrives late
if (AT _L > 0 and ET _L < AT _L )
P _S = 0
else
if (ET _L > T _TH )
P _S = ET _L * W _H
else
P _S = ET _L * W _N
end if
end if
else // truck arrives early
if (AT _E > 0 and ET _L < AT _E )
P _S = 0
else
if (ET _L > T _TH )
P _S = ET _L * W _H
else
P _S = ET _L * W _N
end if
end if
end if

Next, an evaluation method considering a weight among evaluation methods of combinations set according to a diversified dispatch strategy of a plurality of transportation equipment in a container terminal according to the present invention will be described with reference to FIG. 16 .

And the expected tolerance movement time (ET _Travel) determines whether or not the following truck movement allowed time (AT _Travel) (S1501), the back surface of the S1501 phase determination result, 'Yes', rating penalty (P _D) of the tolerance distance traveled is If it is zero (=0) (S1502), otherwise, the evaluation penalty for the tolerance travel distance ( _PD ) is set as the expected tolerance travel time (ET _Travel ) (S1503).

The corresponding program coding is shown in Table 2 below.

Step 2. Evaluation formula considering the weight of evaluation items
If (ET _Travel <= AT _Travel )
P _D = 0
else
P _D = ET _Travel
end

In the end, the total penalty in the evaluation result (P _T) is the following <Equation 1> and the like, evaluation penalty (P _S) rating penalty for the weight (R _S) the multiplied value and the allowance moving distance thereof to the arrival delay It is defined as the sum of values obtained by multiplying (P _D ) by its weight (R _{D ).}

[Equation 1]

P _T = (P _S * R _S ) + (P _D * R _D )

However, the sum of the arrival delay (or waiting), the weight (R _S) and the weight _(D R) of the tolerance for the distance traveled is 1.0.

Finally, an evaluation method in consideration of the weight of a combination set according to a diversified dispatch strategy of a plurality of transportation equipment in the container terminal according to the present invention will be described with reference to FIG. 16 .

The evaluation result inquiry screen of FIG. 16 is a screen that can be inquired about the result of evaluating the combination between the yard truck and the candidate work according to the dispatch strategy (weights for evaluation items and various set values) set by the user, and the dispatch strategy It is possible to provide feedback for adjustment, as shown in FIG. 16 , the evaluation result inquiry screen is a result screen evaluated according to the yard truck list 1710 , the candidate work list 1720 and the dispatch strategy set by the user (1730).

First, the importance of two factors (tolerant travel distance and arrival delay or waiting) for yard truck dispatch optimization can be changed and applied in real time according to the user's settings.

Second, there is an advantage in that the user can register and manage a plurality of dispatching strategies to change the dispatching strategy in real time more easily than the conventional method according to the situation.

Third, more flexible terminal operation is possible as a dispatch strategy suitable for the work plan of each yard truck pool can be used separately.

In the above, the present invention has been described according to an embodiment of the present invention, but changes and modifications made by those of ordinary skill in the art to which the present invention pertains without departing from the technical spirit of the present invention also belong to the present invention.
