Description

  The present invention relates to a work instruction system in a container terminal and a system capable of giving an optimum work instruction.

Conventionally, in a container terminal, a container is loaded and unloaded from a container ship by a number of cargo handling vehicles.
For example, in a container terminal, a container is lowered from a container trailer to a container yard by a transfer crane, a top lifter, or the like, and a container placed in the container yard is loaded on the container trailer.

  By the way, the number of cargo handling vehicles arranged in the container yard is limited, and it is necessary to cope with work that occurs in various places, so that loading and unloading work with cargo handling vehicles is performed efficiently, A work instruction, that is, a dispatch instruction is issued from the management center to each cargo handling vehicle.

  This work instruction is issued to the cargo handling vehicle determined to be suitable for the cargo handling work at the timing when the work instruction is generated (see, for example, Patent Document 1).

JP 2005-75592 A

  However, as described above, it is issued at the timing when the work instruction is generated. However, depending on the current work content or the next work content of the corresponding cargo handling vehicle, it is more efficient to let other cargo handling vehicles perform it. There was a good case.

  Accordingly, an object of the present invention is to provide a work instruction system in a container terminal that can more optimally issue a work instruction to a cargo handling vehicle in the container terminal.

In order to solve the above-described problems, a work instruction system for a container terminal according to the present invention is a work instruction system that issues a work instruction including at least work content and work position to a cargo handling vehicle that performs a container handling work at the container terminal. There,
Work content data holding means holding work contents for each cargo handling vehicle at the present time and work position data holding means holding the work position of each cargo handling vehicle;
A work time for inputting a newly generated work instruction and calculating a time required for the newly generated work for each cargo handling vehicle based on the current work contents and work positions held in the data holding means. The calculation unit, the movement time calculation unit for calculating the time required for the cargo handling vehicle to move to the newly generated work position, and the work time and movement time calculated by these two time calculation units are added to obtain the work completion time. A work completion time calculation means comprising a completion time calculation unit for calculating;
Optimal vehicle detection means for detecting a cargo handling vehicle having the shortest work completion time determined by the work completion time calculating means;
A work hold judging means for judging whether the work instruction to be immediately issued or temporarily put on the cargo handling vehicle detected by the optimum vehicle detecting means;
A delivery means for delivering the work instruction to the detected cargo handling vehicle when it is determined that the work instruction should be issued by the work hold judging means;
A work instruction data holding means for holding the work instruction when the work hold determining means determines that the work instruction should be held;
Data for instructing the work completion time calculating means to input the work instruction data when it is determined whether or not to cancel the hold of the work instruction data held by the work instruction data holding means. It consists of a hold release determination means,
Further, when the determination criteria for the hold in the work hold determination means is that the work number of the cargo handling vehicle detected by the optimum vehicle detection means is greater than the set number, the work handling vehicle is performing work to be preferentially performed and It is assumed that the cargo handling vehicle does not exist in the container placement lane to perform the work.

Furthermore, the work instruction method in the container terminal of the present invention is a work instruction method for issuing a work instruction consisting of at least work content and work position to a cargo handling vehicle that performs container handling work at the container terminal,
When a new cargo handling operation occurs, based on the current work content and position of each cargo handling vehicle, the work is completed for each cargo handling vehicle until it is finished and moved to the work location of the newly generated cargo handling operation. A work completion time calculation process for obtaining work completion times,
An optimum vehicle detection step for detecting a cargo handling vehicle in which the work completion time of each cargo handling vehicle determined in the work completion time calculation step is the shortest;
A work hold determination step for determining whether the work instruction should be immediately issued or temporarily held in the cargo handling vehicle detected in the optimum vehicle detection step;
A distribution step of distributing the work instruction to the corresponding cargo handling vehicle when it is determined that the work instruction should be issued in the work hold determination step;
A work instruction data hold step for holding the work instruction data when it is determined that the work instruction should be held in the work hold determination step;
It is determined whether or not the work instruction data held in the work instruction data holding process is to be released based on a newly generated event such as a work instruction, and when it is decided to release the work instruction data, It is a method of inputting to the above work completion time calculation step,
In addition, when the number of work operations of the cargo handling vehicle detected by the optimum vehicle detection means is larger than the set number, the determination criteria for the suspension in the work suspension determination process is the case where the cargo handling vehicle is performing work to be preferentially performed and This is a method in which the cargo handling vehicle does not exist in the container placement lane to perform the work.

  According to the work instruction system and the work instruction method described above, in response to a new work instruction, an optimum cargo handling vehicle is detected in consideration of the work instruction in each cargo handling vehicle at the present time, and the current work of the cargo handling vehicle is immediately executed. If it is not possible, the work instruction is suspended, and a new work instruction is issued when an event such as a new work instruction occurs. Therefore, a more optimal work instruction can be issued.

Hereinafter, a work instruction system in a container terminal according to an embodiment of the present invention will be described based on specific examples.
First, the overall configuration of the container terminal will be schematically described with reference to FIG.

  The container terminal 1 is provided with a container yard 3 in which a container C is temporarily placed (stored) near a quay 2 where the container ship S is berthed, and a trailer or the like is provided near the container yard 3. A reception gate 4 for managing the loading and unloading of the container C by the transport vehicle A is provided, and a management building 5 for managing the entire container terminal 1 is provided. The management building 5 has a container terminal management system which is a computer system for instructing various operations such as loading and unloading of the container C, loading (loading) of the container C into the container ship S or unloading (unloading). (Hereinafter simply referred to as a management system).

  The container yard 3 is provided with a large number of container loading lanes R for placing the containers C in a row, and most of the cargo handling work occurring at the container terminal 1 occurs at the container yard 3. This relates to the handling of the container C.

  The loading and unloading operations of the container C on the container ship S are performed by the gantry crane 6 disposed on the quay 2, and the loading and unloading operations of the container C on the transport vehicle A in the container yard 3 are mainly performed. It is performed by a cargo handling vehicle 7 such as a transfer crane (RTG). In addition to the transfer crane, a top lifter or the like is also used.

  By the way, the main item of the management system provided in the management building 5 is to detect (search) a cargo handling vehicle capable of quickly processing the generated cargo handling work, in other words, to dispatch an optimal cargo handling vehicle. is there. For the container terminal as a whole, it is to give a work instruction such as loading or unloading of a container to a transport vehicle, a cargo handling vehicle, a gantry crane or the like. This work instruction includes at least work content data and work position (vehicle position) data. In addition, issuing a work instruction to a cargo handling vehicle has the same meaning as issuing a dispatch instruction. For the sake of explanation, if it is better to use a dispatch instruction than a work instruction, The phrase “allocation instruction” is used alone or in combination with a work instruction.

Here, a work instruction (allocation instruction) will be briefly described.
There are two types of dispatching: manual dispatching, where the yard planner gives instructions, and automatic dispatching, where the management system gives instructions. This automatic dispatching also includes ship work, gate work, and marshalling work.

  The ship operation is an operation for loading or unloading the container C directly on the container ship S, and it is necessary to perform the operation with priority (that is, the ship operation is performed with priority), and is performed in real time.

  On the other hand, the gate work is a work that occurs when the transport vehicle A arrives at the reception gate 4, that is, a work associated with the loading and unloading of the container C. Specifically, the container C is lowered to the container yard 3, 3 is a work of loading the container C placed on the transport vehicle A, and the work instruction system according to the present invention distributes this work instruction to the cargo handling vehicle 7.

  The marshalling work is for organizing the containers C placed in the container yard 1, and a work instruction is issued (issued) at an arbitrary timing by the yard planner.

The work instruction system will be described below.
First, a schematic configuration of the work instruction system will be described with reference to FIG.
This work instruction system includes work content data holding means (which is a database) 11 that holds work content data among work instructions based on cargo handling work for each cargo handling vehicle 7 at the present time, and the current status of each cargo handling vehicle 7. Work position data holding means (database) 12 that holds the work position, and work instructions data (holding dispatch data), which will be described later, are held together with work instructions (vehicle dispatch request) based on the newly generated cargo handling work. Then, a work instruction data holding means (a database, which can also be called a dispatch request data holding means) 13 for delivery to a processing unit such as a subsequent calculation, and a work instruction (a dispatch request) sent from the work instruction data holding means 13 ) That is, based on the work content and work position, work for calculating the time required to finish the work content for each cargo handling vehicle 7 The time calculation unit 14a, the movement time calculation unit 14b that calculates the time required for the cargo handling vehicle 7 to move to the work position, and both times obtained by the time calculation units 14a and 14b are added to complete the work. Work completion time calculating means 14 having a completion time calculating section 14c for calculating the time, and optimum vehicle detection means 15 for detecting a cargo handling vehicle having the shortest work completion time obtained by the work completion time calculating means 14. Then, work hold determination means (which can also be referred to as vehicle allocation hold determination means) 16 for determining whether the optimum cargo handling vehicle 7 detected by the optimal vehicle detection means 15 should immediately perform the work or temporarily hold the work. When the work hold determining means 16 determines that a work instruction should be issued (should be dispatched), the work instruction is distributed to the corresponding cargo handling vehicle 7. Work instruction data hold for temporarily holding the work instruction data when it is determined that the work instruction should be held by the distribution means (also referred to as a dispatch instruction means) 17 and the work hold determination means 16 When it is determined whether or not to release the means (reserved dispatch data holding means) 18 and work instruction data (holding dispatch data) temporarily held in the work instruction data holding means 18 It is composed of a data hold release determination means (also referred to as a vehicle allocation hold release determination means) 19 for instructing to send the work instruction data held in the work instruction data holding means 18 to the work instruction data holding means 13. .

A computer is used as at least each of the constituent members such as the calculation means and the determination means, and the function is executed by a program.
Next, the work instruction operation (allocation instruction operation), that is, the work instruction method in the work instruction system according to the present invention will be described.

  The contents of the cargo handling work for all the cargo handling vehicles 7 at the present time, that is, the work content data for all the cargo handling vehicles 7 are held in the work content data holding means 11 and the work position data of all the cargo handling vehicles 7 are the work positions. It is assumed that it is held in the data holding means 12.

  In this state, for example, when the transport vehicle A loaded with the container C arrives at the reception gate 4, predetermined data (container data, reception data for loading containers such as destinations) is sent from the reception gate 4 to the management system (management). The system sends a confirmation message), and in this management system, work contents such as the placement location (work position) and unloading of the container C in the container yard 3 are determined, and work instructions ( A dispatch request is automatically issued.

  This work instruction is input to the work completion time calculating means 14 via the work instruction data holding means 13, and the work time calculating section 14a calculates the work time for ending the work content, and at the same time, the travel time. In the calculation unit 14b, a plurality of cargo handling vehicles 7 close to the work position are selected (all cargo handling vehicles existing in the container yard can be targeted), and each of the selected cargo handling vehicles 7 is set to the work position. The time required for the movement is calculated, and both the obtained times are input to the completion time calculation unit 14c and added to obtain the work completion time.

Next, the determined work completion time is input to the optimum vehicle detection means 15, and the cargo handling vehicle C with the shortest work completion time is detected as the optimum vehicle.
Here, the optimal vehicle detection method will be described in detail.

Here, in order to simplify the description, a case where the lane arrangement is as shown in FIG. 3 will be described.
As shown in FIG. 3, lanes R (R1 to R3) for placing containers C are juxtaposed in three rows (hereinafter referred to as A row, B row, and C row), and for each lane R, It is assumed that a passage P that divides these lanes R is provided at the center and is divided into front and rear. In the drawings, the right side is referred to as a front lane (R1a to R3a) and the left side is referred to as a rear lane (R1b to R3b).

Three specific examples in the case where a new gate work (the same as the ship work) occurs under the above-described preconditions will be described.
(1) As shown in FIG. 3, in each of the three lanes R (R1 to R3), cargo handling vehicles 7 (7A to 7C) are arranged, and each of these cargo handling vehicles 7 has no work instruction. To do.

In this state, when a work instruction for loading the container C in the lane R2 of the B row and the front lane R2a into the transport vehicle is issued, the work is performed on the cargo handling vehicle 7B existing in the lane R2 of the B row. Instructions are delivered.
(2) As shown in FIG. 4, the handling vehicles 7A and 7C are arranged (exist) in the lane R1 in the A row and the lane R3 in the C row, and work instructions are given to the respective handling vehicles 7A and 7C. There shall be no.

In this state, when a work instruction is issued to load the container C of the front lane R2a in the lane R2 of the B row where no cargo handling vehicle is arranged, the work completion time by the cargo handling vehicles 7A and 7C is shortened. Work instructions are distributed to the cargo handling vehicle. Here, it is delivered to the cargo handling vehicle 7C in the C row with a short travel time.
(3) As shown in FIG. 5, cargo handling vehicles 7 (7A to 7C) are arranged in three lanes R (R1 to R3), respectively, and work instructions are given to the A and C handling vehicles 7A and 7C. The cargo handling vehicle 7B arranged in the front lane R2a of the B row has no reference time (predetermined time for completion of work determined in advance on the terminal side, for example, about 15 minutes). It is assumed that a work instruction has been issued so that it can be completed.

  In this state, when an operation instruction for loading the container C in the rear lane R2b of the B row into the transport vehicle 7 is issued, it is not issued to the loading vehicle 7B existing in the same B row ( The work that is occurring in 7B or the work that is newly issued will be delayed), so that the work is carried out in the row A or C row handling vehicles 7A and 7C that do not have work and the completion time of the work is shortened. Instructions are delivered.

  In this way, when the optimum vehicle detection means 15 detects a cargo handling vehicle to which a work instruction is to be distributed, whether this cargo handling vehicle is input to the work hold determination means 16 and should be immediately executed (Y : Dispatch instruction) or whether to temporarily hold (N: dispatch dispatch) is determined.

At this time, the following three criteria are provided for determining whether or not to hold.
1. 1. When the number of work of the corresponding cargo handling vehicle exceeds the preset number 2. When the corresponding cargo handling vehicle is executing priority work (priority work) When the applicable cargo handling vehicle does not exist in the lane and the cargo handling vehicle existing in the adjacent lane is performing other work. It is determined that the (allocation instruction) is to be temporarily reserved (also referred to as pooling), and this work instruction is held by the work instruction data holding means 18.

Here, the hold instruction operation will be specifically described based on the same drawing as that used in the description of the work instruction.
As shown in FIG. 6, it is assumed that cargo handling vehicles 7A and 7C are arranged in the lane R1 in the A row and the lane R3 in the C row, and these cargo handling vehicles 7A and 7C are working.

  In this state, when an operation instruction is issued to load the container C in the lane R2 in the B row where no cargo handling vehicle is arranged on the transport vehicle, each of the cargo handling vehicles 7A and 7C in the adjacent lanes R1 and R3 performs other operations. Since it is being executed (corresponding to the above-mentioned third criterion), it is determined that this work instruction should be temporarily suspended. That is, this work instruction is held by the work instruction data holding means 18.

  Although not specifically described, it is determined that the work instruction should be temporarily held even when the first or second determination criterion is satisfied, and the work instruction data holding means 18 is determined. Is put on hold.

  Of course, if none of the above three criteria is met, the work instruction data is sent to the distribution means 17 and distributed to each cargo handling vehicle 7 via radio. At the same time, the work instruction data is sent to the work content data holding means 11 and the work position data holding means 12, and when there is a next work instruction (distribution), data for calculating work completion time and detection of the optimum vehicle. Used as business data. In addition, the work instruction data is distributed to necessary places (for example, optimum vehicle detection means, work hold determination means, etc.) other than the data holding means 11, 12. When the work on the cargo handling vehicle 7 is completed (finished), a work completion report is sent to the management system side, and the work data is naturally distributed from the management system side to the gantry crane 6 as well. Yes.

  The work instruction data held in the work instruction data holding means 18 is always determined by the data hold release determining means 19 whether or not the hold state should be released. That is, the data hold release determination means 19 receives a trigger (which is an event and can also be called a hold release command) as a hold release condition. When this trigger is input, the hold is released. Then, the work instruction data is sent to the work instruction data holding means 13, and a work instruction (relocation request) is performed again from here.

  The trigger for releasing the hold state is, for example, when there is a new work instruction (request for dispatch), when any work is completed, or when a predetermined time (predetermined time) has passed.

  When the work instruction is issued again, it is sent to the work completion time calculation means 14 via the work instruction data holding means 13 and the work instruction is again transmitted to the cargo handling vehicle in the same procedure as described above. be delivered.

Here, the outline contents of the above-described work instruction method are represented in the stroke format as follows.
That is, the work instruction method in the container terminal is a work instruction method for issuing a work instruction including at least work content and work position to a cargo handling vehicle that performs container handling work at the container terminal,

In the above work instruction method,
When the number of work loads on the cargo handling vehicle detected by the optimum vehicle detection means is greater than the set number, the work handling judgment process is performed when the work handling vehicle should perform with priority. This is a method in which the vehicle does not exist in the container placement lane to perform the work.

  In this way, in response to a new work instruction (a dispatch request), the optimum work load in consideration of the work instruction in each cargo handling vehicle at the present time, that is, the cargo handling vehicle that the work instruction can be performed quickly (or earliest) is detected. When the current work of this cargo handling vehicle cannot be immediately executed, the work instruction is temporarily held, and when a predetermined trigger, that is, a hold release command is issued, a work instruction (vehicle dispatch request) is issued again. As a result, it is possible to always give an optimal work instruction.

  In the above embodiment, the work content data holding means 11 and the work position data holding means 12 have been described as being provided separately, but they may be provided in the same means, and the work completion time calculating means 14 and Similarly, the optimum vehicle detection means 15 may be provided in the same means, not separately. Furthermore, without providing the work instruction data holding means 13, a new work instruction (reservation request) and a re-operation instruction (re-relocation request) may be directly input to the work completion time calculation means 14.
