The outflow jobs of the container include one of a loading work, an unloading work, and a changing work.

Description

Efficient Device Location Determination Considering Outflow Behavior of Containers {Method for Locating Container at a Container Yard respecting the Outflow job of a Container}

The present invention relates to a method for determining the position of a container device in a vertical arrangement device of an automated container terminal, and in particular, to determine the location by classifying the container type according to the way in which the container is discharged from the storage area to improve the overall terminal productivity. It relates to a device positioning method that can be.

Containers work in terminals and are stacked in storage areas before going out. In this case, the storage area is a place where the container is stacked waiting for work before being transported abroad or domestically, such a storage area is divided into a horizontal arrangement and a vertical arrangement in accordance with the arrangement relationship of the quayside that the vessel is docked. As a result, the work performed in the terminal is performed mainly in the equipment field.

The work that is carried on the outside of the rack by the external truck is carried in, and the work that enters the dock is called unloading. The work that is carried out is called the loading work. Among these, the import work, the unloading work, and the unloading work, and the unloading work coming out of the equipment shop are referred to as container spill work.

These inflow and outflow operations are generally performed in pairs. In other words, in case of exported containers, they are loaded into the yard and loaded, and the ships are loaded and then shipped overseas. In the case of imported containers, they are unloaded and stacked in the yard. In addition, in the case of transshipment containers, they are unloaded and stacked in the storage area, and then dropped again to go abroad.

On the other hand, when the container is introduced into the device, the location of the device is determined in this case, considering the convenience of the spill operation. In other words, the container to be loaded and loaded or the container to be loaded should be installed at the position where the delay is minimal when loading. In addition, the container to be unloaded and taken out is stacked so as to avoid rehandling as much as possible because it does not know which external truck will enter.

However, the prior art considers the characteristics of the container itself rather than the characteristics of the work. That is, in general, a specific area is designated according to the type of container and a request of a shipper or a shipping company, and the location is determined so that the container is installed in the area. However, because it is impossible to know exactly when a container should belong to the area, the reserved area is likely to be a waste of space. In addition, when the information of the container used for the area reservation is different from the actual information, the area may be a wrong area.

In addition, the conventional techniques have been developed for a horizontal arrangement device in which the container arrangement of the inner wall and the installation device is parallel as shown in FIG. However, the horizontal arrangement device and the vertical placement device as shown in FIG. 2 are different from each other due to the different arrangement of the container, and the moving distance of the crane and the location of the container are different, and the equipment is also different. It's hard to guarantee.

Therefore, the present invention has been made to solve the above problems, the vertical arrangement device is arranged orthogonal to the inner wall, the device in consideration of the characteristics according to the type of work performed in the container terminal rather than the specific of the container itself. Its purpose is to provide an efficient device positioning method that considers the outflow work characteristics of containers that can increase the space utilization rate of the device and determine the proper device location to reduce the delay that can occur in the terminal.

Another object of the present invention is to reflect the trend of the container terminal is changing and to devise an operation method according to it, to determine the device location by dividing the container into containers after loading, unloading, transshipment, reloading, carrying out after rehandling To provide a way.

It is still another object of the present invention to provide a method for determining device location suitable for each terminal by adjusting a weight multiplied by each element.

In order to achieve the above object, a feature of an efficient device positioning method in consideration of the outflow work characteristic of a container according to the present invention includes (A) extracting and confirming information of a container to be transported to a device, and (B) checking the same. Calculating an evaluation value for each candidate device position according to the type of spilling operation of the container based on the container information, and (C) determining the candidate device position having the lowest evaluation value among the calculated evaluation values as the device location of the container. It includes the steps to.

Preferably, the step (B) is carried out by (B1) a first sorting step of sorting out what kind of work is the outflow work of the container by using the identified container information, and (B2) dropping through the first sorting step And selecting each of the job, the export job, and the transshipment job, and evaluating the candidate device location by the weighted sum of at least one device positioning element for each job.

An efficient device positioning method in consideration of the outflow work characteristic of the container according to the present invention as described above has the following effects.

First, in consideration of the characteristics of the work occurring in the vertical arrangement, there is an effect that can determine the location of the device when the container inflow can improve the efficiency of the outgoing work within the range that does not interfere with the work currently being performed.

Second, the rehandling work also provides a clear location rather than an arbitrary location in the short distance, which can prevent additional rehandling situations.

Third, there is an effect that can determine the location of the device according to the characteristics of the work performed in the container terminal to reduce the additional work caused by the container loaded in an inappropriate position or the work delay caused by it.

Fourth, since the characteristics of the container itself are considered rather than the characteristics of the work, there is an effect that the delay of the work occurs less when the container leaves the device.

Other objects, features and advantages of the present invention will become apparent from the following detailed description of embodiments with reference to the accompanying drawings.

Referring to the accompanying drawings, a preferred embodiment of an efficient device positioning method in consideration of the outflow operation characteristics of the container according to the present invention will be described. However, the present invention is not limited to the embodiments disclosed below, but can be embodied in various forms, and only the present embodiments are intended to complete the disclosure of the present invention and to those skilled in the art to fully understand the scope of the invention. It is provided to inform you. Therefore, the embodiments described in the specification and the drawings shown in the drawings are only the most preferred embodiment of the present invention and do not represent all of the technical idea of the present invention, various modifications that can be replaced at the time of the present application It should be understood that there may be equivalents and variations.

3 is a flowchart illustrating an efficient device positioning method in consideration of the outflow work characteristics of the container according to an embodiment of the present invention.

Referring to FIG. 3, first, information of a container to be transferred to a device head is extracted and confirmed (S100), and an evaluation value is calculated for each candidate device position according to the type of spilled work of the container with reference to the confirmed container information. (S200).

Subsequently, the candidate device position having the lowest evaluation value among the calculated evaluation values is determined as the device position of the container (S300), and the device position determined by the internal transport vehicle (AGV) or the central operation control system is output (S400).

4 is a flowchart illustrating a method of calculating an evaluation value for each candidate device position of FIG. 3 in detail.

Referring to Figure 4, using the information of the container first identified what kind of work is the discharge operation of the container (hereinafter referred to as "first screening") (S210). For reference, the outflow work of containers can be divided into loading work, export work, and transshipment work.

In the first sorting result (S210), if the container to be loaded is a container to be loaded, whether the container to be loaded is newly introduced or whether the container is already loaded and stacked in a storage area and is to be reprocessed by another operation. (Hereinafter referred to as "second screening") (S220).

In the second screening result (S220), when the current job is a new carry-in operation of the container, the evaluation values of candidate device positions are calculated through Equation 1 (S230).

Where x is the stack number (∈ {1,…, 10}) of the candidate position, y is the bay number (∈ {1,…, 41}) of the candidate position, and s is the length of the loaded container (∈ {20, 40). }), o indicates the number of days left before shipment (∈ {1,2,3}).

Equation 1 is a formula for determining the position of the device at the time of loading the container to be loaded and stacked in the storage device to be discharged through the loading operation. The score G according to the group information in the case of loading containers to be loaded takes into account the order of arrival and the group information of the mother ships of the containers loaded at the candidate device locations in order to minimize the rehandling work. In particular, containers working on the same vessel are loaded on the same stack as much as possible to increase space utilization.

These import containers can be divided into containers to be shipped within three days and containers to be shipped after three days, depending on the remaining days until shipment. The former will be released soon, so be sure to follow the shipping order to avoid rehandling as much as possible. In the latter case, since the group information is not yet determined in the case of a future export container, the block space is minimized.

In the case of the fetch container, it is important to position it in order to benefit the job, since its outflow work is classified as the most important job in the terminal. Therefore, in this specification, the preferred position P according to the spilling operation is used to load in a better position by utilizing existing knowledge.

In the case of such an import container, it may have a distribution of a preferred position according to an import point as shown in FIG. 5. Containers brought in three days prior to loading may not have group information yet, and other work may be taking place. In the case of containers brought in two days before loading, the group information has been determined to some extent, but other work may still be performed, so it is likely to be distributed in the middle of the block for ease of loading. In addition, containers that are brought in the day before loading are sure to be distributed on the sea side of the block for ease of operation because they are reliable information and containers are to be released on the next day. This score is represented by the equation (1).

Next, in the case of the second screening result (S220), when the current job is a job of rehandling a container that has been previously loaded and stacked, an evaluation value of candidate device positions is calculated through Equation 2 (S240).

Where x is the stack number (∈ {1,…, 10}) of the candidate position, y is the bay number (∈ {1,…, 41}) of the candidate position, and s is the length of the loaded container (∈ {20, 40). }), o indicates the number of days left before shipment (∈ {1,2,3}).

는 기존에 컨테이너가 장치되어 있던 곳으로부터 새로운 후보 장치위치까지의 거리를 베이 개수로 반환하는 함수이다. 나머지는 앞에서 설명한 것과 동일하다. 적하될 컨테이너는 재취급이 되더라도 그 위치가 중요하지만 임시로 위치를 옮기는 작업이기 때문에 적하 시점에 따른 선호 위치를 고려하지는 않는다. 이것을 점수화하여 수식으로 나타낸 것이 수학식 2이다.Equation 2 is a formula for evaluating the candidate position when the containers are stacked and reloaded for the operation of other containers, and the positions are shifted. here

Is a function that returns the number of bays from the location where the container was previously installed to the new candidate device location. The rest is the same as described earlier. Although the container to be loaded is repositioned, its position is important, but since it is a temporary relocation operation, it does not consider the preferred position according to the loading time. This score is represented by the equation (2).

On the other hand, the first sorting result (S210), if the container to be imported is the container to be taken out currently whether the container is to be unloaded or whether the container is already unloaded and stacked in the storage area to be handled again by another operation Screening (hereinafter referred to as "third screening") (S250).

In addition, when the third screening result (S250) and the current job is not a rehandling operation, the evaluation values of candidate device positions are respectively calculated through Equation 3 (S260).

Where x is the stack number (∈ {1,…, 10}) of the candidate position, y is the bay number (∈ {1,…, 41}) of the candidate position, and s is the length of the loaded container (∈ {20, 40). }).

Equation 3 is an equation for evaluating candidate positions to determine the device position of the container to be carried out. Where P returns the score for the preferred location according to the ease of the export operation. However, for the container to be taken out, it is not known exactly when to take it out, so this value is better to be evaluated as the shorter moving distance of the land crane. This score is represented by the equation (3).

Next, in the case of the third sorting result (S250), and the export operation for rehandling a container in which the current job is previously quantified and accumulated, the evaluation values of candidate device positions are calculated through Equation 4 below (S240).

Where x is the stack number (∈ {1,…, 10}) of the candidate position, y is the bay number (∈ {1,…, 41}) of the candidate position, and s is the length of the loaded container (∈ {20, 40). }).

는 후보 장치위치에서 육측 HP까지의 거리를 반환한다. 이것을 점수화하여 수식으로 나타낸 것이 수학식 4이다.Equation (4) is an equation for evaluating candidate device positions when the container to be carried out, which is stacked in the storage space, is handled again, and has the same structure as in Equation (2). However, Equation 2 targets the container to be loaded, and Equation 4 targets the container to be exported, and thus, different outflow points of the two containers are obtained. That is, here

Is equal to the distance from the container's current position to the candidate position to be rehandled,

Returns the distance from the candidate device location to the hexagonal HP. This score is represented by the equation (4).

Finally, in the case of the first screening result (S210) and the container in which the introduced container is to be transferred, the evaluation values of candidate device positions are calculated through Equation 5 (S280).

Where x is the stack number (∈ {1,…, 10}) of the candidate position, y is the bay number (∈ {1,…, 41}) of the candidate position, and s is the length of the loaded container (∈ {20, 40). }), o indicates the number of days left before shipment (∈ {1,2,3}).

Equation 5 is similar to Equation 3 for evaluating the device position of the dropping container in view of the nature of the job. However, in the case of transshipment containers, since the distance from the inflow point to the device position and the distance from the device location to the outflow point are the same, one of the two values is used here. This score is represented by the equation (5).

Then, the evaluation values of the at least one candidate device position calculated as described above are set as candidate device position evaluation values for respective containers (S290).
