An embodiment of the present invention provides a yard trailer scheduling method, and referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of a yard trailer scheduling method according to the present invention.
In this embodiment, the yard trailer scheduling method includes the following steps:
step S10: and when receiving a loading and unloading command, acquiring the number of target working trailers of the target shore bridge and the number of current working trailers.
It should be noted that the main body of the method of this embodiment may be a yard trailer scheduling device having data processing, network communication and program running functions, such as a computer or a control computer, or may be other electronic devices capable of implementing the same or similar functions.
It should be noted that the scheduling information may be command information automatically generated after a certain time interval, where the command information includes: the method comprises the steps of distributing task information to trailers, properly loading and unloading the onshore bridge, properly unloading the task amount and the like, wherein loading and unloading instructions are used for starting scheduling operation of the trailers in the yard.
It will be appreciated that, since the quay is used to transport cargo, a quay container crane (QC) is required to load and unload the container ship, wherein the quay container crane, i.e. a quay crane, is a specialized device specially used for the container quay to load and unload the container ship, and is generally installed on the quay of the port quay.
In this embodiment, since the trailer scheduling is performed on the basis of the entire yard, the target shore bridge may be any shore bridge in the yard, and this embodiment is not particularly limited thereto.
In specific implementation, in order to manage the dispatching of the target shore bridge trailer, the target shore bridge can be classified first, that is, the shore bridges participating in the operation are classified initially according to importance.
Further, before the step S10, the method further includes:
the method comprises the steps of obtaining shore bridge information in a storage yard, and extracting information of work to be completed in the shore bridge information;
grading the shore bridges in the yard according to the to-be-finished work information to obtain shore bridge priority information;
assigning a target number of working trailers based on the shore bridge priority information.
It should be understood that the shore bridge information includes loading and unloading value, polling time interval, minimum distance for loading and unloading, preset time parameter for dispatching vehicles in advance and position distance information of each shore bridge in the storage yard;
in addition, wait to accomplish the total task volume that the work information still need load and unload that corresponds the bank bridge promptly, however, because in the actual operation process, the bank bridge can not once only be with all goods handling work during operation, consequently in this embodiment, suitable dress is suitable for the value of unloading, is suitable for the work load of loading and unloading promptly, and suitable dress is suitable for the value of unloading of each bank bridge and is different can carry out the classification to the bank bridge according to the suitable dress of each bank bridge and is suitable for the work load of unloading, and according to the priority difference of bank bridge, the corresponding trailer quantity is different, for example: the suitable loading and unloading value of the shore bridge A is 1t, the suitable loading and unloading value of the shore bridge B is 2t, the grade of the shore bridge A is the second priority, the priority of the shore bridge B is the first priority, correspondingly, the number of the trailers distributed by the shore bridge A can be 1, and the number of the trailers distributed by the shore bridge B can be 2.
In this embodiment, the land-bridge priority may be divided into three levels: the highest priority, the first priority and the second priority, wherein the highest priority corresponds to an adaptive loading and unloading value of N1; a second priority corresponding to an applicable load and unload value of N2; the loading and unloading value corresponding to the third priority is N3; in general N1 is greater than N2 and N2 is greater than N3, and there is one maximum matching vehicle per shore bridge, i.e. the maximum number of trailers that a shore bridge can accommodate.
The upper limit of the number of trailers that can be accommodated by each shore bridge is set according to a weighted value, the weighted value can be set by a user, the factors influencing the weighted value of the number of trailers are considered first for distance factors, the order property is next, and then the congestion condition of the yard column, the queuing and waiting condition of the working point and the priority rule are sequentially set, so that the weighted value is set, in the embodiment, the weighted value can be 2, 1.8, 1.2, 1.5, 1 corresponds to the distance factors, the order property, the queuing and waiting condition of the congestion condition and the priority principle.
It can be understood that the target working trailer number refers to the trailer number allocated according to the priority of the shore bridge, the allocation principle is that the shore bridge with the residual instructions smaller than the preset value is allocated according to the requirement, and if the residual instructions are insufficient, the residual instructions are allocated according to the proportion of the shore bridge occupying the required total number; and if the surplus exists, subtracting the required number of the shore bridges smaller than the preset value, and distributing the surplus according to the proportion of the total number of vehicles to be distributed by the shore bridges of each grade.
It is easy to understand that the number of the current working trailers is the number of trailers which are suitable for loading and unloading under the current state of the target shore bridge, and generally, the number of the current working trailers can be smaller than the number of the target working trailers due to the influence of environmental factors.
Step S20: and acquiring the number of idle trailers when the number of the current working trailers is less than the number of the target working trailers.
It should be noted that the number of idle trailers refers to the sum of the number of trailers without a task or trailers to complete a task in the yard.
In a specific implementation, when the number of the current working trailers is smaller than the number of the target working trailers, the loading and unloading value of the target shore bridge is still vacant, and additional trailers are required to be added to improve the loading and unloading efficiency.
In this embodiment, the basis for determining whether the trailer is idle according to the working conditions of the trailer in different states is different, for example: under the condition of loading, at most one trailer to be idle is arranged on each rod, and the existing shore bridge can provide accurate position information and lanes allocated to the shore bridge, so that the accurate position of loading the tank by the shore bridge can be determined. The following three conditions will be met: 1. the trailer enters a lane to which the shore bridge belongs; 2. the distance between the trailer and the loading position of the shore bridge is less than the minimum distance to be idle for loading; 3. the loading order assigned by the trailer is under the shore bridge; and to exclude hanging non-shippable trailers. The trailer closest to the position of the shore bridge container is selected as the trailer which is about to idle below the shore bridge.
In the case of ship unloading, the ship unloading is to distribute idle trailers to each yard operation device, each yard operation device obtains the truck to be completed according to the following rules, and a Rubber-tyred Gantry crane (RTG) is selected. Namely, the box is the last box of the vehicle or the first box of the vehicle, and the two boxes of the vehicle are in the same shell or adjacent shells. If the box is the last box of the vehicle, the vehicle is directly considered to be idle. If the first box of the vehicle is the first box of the vehicle and the two boxes of the vehicle are in the same shell or adjacent shells, the time of the vehicle to be completed is the time of adding the shell moving time of the rubber tire gantry crane to the operation time of the rubber tire gantry crane. If the upcoming time for the trailer is less than the current time plus the preset time for dispatch ahead, the vehicle may be considered to be in an upcoming idle state.
Under the condition of box moving, a rubber tire portal crane of a target storage yard is selected, and if the box is the last box of the vehicle, the vehicle is directly considered to be idle. If the first box of the vehicle is the first box of the vehicle and the two boxes of the vehicle are in the same shell or adjacent shells, the time of the vehicle to be completed is the time of the rubber tire portal crane operation plus the shell moving time of the rubber tire portal crane.
Step S30: and acquiring the quantity of the loading and unloading commands, and determining the quantity of the target trailers according to the quantity of the loading and unloading commands and the quantity of the idle trailers.
In a specific implementation, there may be situations where the number of loading orders is not consistent with the number of empty trailers, for example: the loading and unloading instruction quantity is more than the quantity of idle trailers, so that the quantity of idle trailers which can be called is not enough to meet the requirement, and at the moment, the existing idle trailers are used as the target trailer quantity; meanwhile, the quantity of the loading and unloading instructions is less than that of the idle trailers, so that the quantity of the idle trailers which can be called is redundant, and only the quantity of the trailers with the same quantity of the loading and unloading instructions can be called, namely the quantity of the loading and unloading instructions is used as the quantity of the target trailers.
Step S40: and carrying out trailer matching through a preset trailer matching model to obtain target trailers corresponding to the number of the target trailers, and carrying out scheduling operation on the target trailers according to the loading and unloading instructions.
It should be noted that the preset trailer matching model is used for selecting a target trailer corresponding to the number of the target trailers in the yard, and moving the target trailer to the target location for loading and unloading according to the loading and unloading command price.
In this embodiment, the loading and unloading command includes: the method comprises the steps of loading instructions, unloading instructions and box moving instructions, wherein three trailer queues can be determined according to the three instructions, and the three trailer queues are respectively a loading queue, an unloading queue and a box moving queue.
When the trailers are controlled to form a loading queue according to the loading instruction to carry out loading operation, the loading queue can be activated to sequence by preset loading instructions, and loading operation is carried out according to the sequence of the queue. And if the number of the carrying state instructions in the current shipping queue meets the set loading number, no instruction is selected to participate in trailer matching. If not, selecting the activating instructions with the difference quantity between the adaptive number and the carrying state instruction number according to the instruction sequence in the queue. If the instruction priority exists in the queue, preferentially selecting an instruction with the priority;
in addition, when the trailers are controlled to form the ship unloading queue according to the ship unloading command to carry out ship unloading operation, the ship unloading queues activated by the ship unloading commands with preset values can be sequenced, and proper unloading operation is carried out according to the queue sequence. And if the number of the dispatched state instructions in the current ship unloading queue meets the set unloading number, the instructions are not selected to participate in trailer matching. If the number of the eligible state instructions is not satisfied, selecting the activated state instructions with the number of the difference value between the number of the eligible state instructions and the number of the dispatched state instructions according to the instruction sequence in the queue;
the selection of the box moving instructions in the plurality of activated box moving queues is subject to the following rule, the congestion judgment of the source position and the target position of the box moving instructions is carried out, and the selection of the box moving instructions is carried out according to the congestion conditions of the two positions. Preferentially selecting a box moving instruction with the source position and the target position not blocked; secondly, selecting a box moving instruction with an uncongested source position; and selecting a box moving instruction with a target position not blocked, and finally selecting a box moving instruction with a source position and a target position both blocked.
The embodiment discloses that when a loading and unloading command is received, the number of target working trailers of a target shore bridge and the number of current working trailers are obtained; when the number of the current working trailers is smaller than the number of the target working trailers, acquiring the number of idle trailers; acquiring the quantity of loading and unloading instructions, and determining the quantity of target trailers according to the quantity of the loading and unloading instructions and the quantity of idle trailers; and carrying out trailer matching through a preset trailer matching model to obtain target trailers corresponding to the number of the target trailers, and carrying out scheduling operation on the target trailers according to the loading and unloading instructions. This embodiment is through the trailer operating condition who detects target bank bridge, when current work trailer quantity is less than target work trailer quantity, it is not enough to accomplish loading and unloading work on time to judge the trailer quantity of target bank bridge, need select the trailer of a certain amount through predetermineeing trailer matching model promptly, carry out scheduling work, the actual data through work trailer judges whether need carry out the trailer dispatch, the efficiency of trailer full-scale dispatch has been improved, the trailer dispatch need rely on artificial experience to make the dispatch decision among the prior art has been avoided, the not high technical problem of efficiency.
Referring to fig. 3, fig. 3 is a schematic flow chart of a yard trailer dispatching method according to a second embodiment of the present invention.
Based on the first embodiment, in this embodiment, the step S30 includes:
step S301: and when the loading and unloading command number is larger than the idle trailer number, recording the idle trailer number as a target trailer number.
It should be noted that, when the number of loading and unloading instructions is greater than the number of idle trailers, the number of idle trailers that can be called is insufficient to meet the demand, and at this time, the existing idle trailers are used as the target trailer number, and a corresponding number of trailers are selected through a preset trailer matching model to perform scheduling operations, for example: the loading and unloading command quantity is 5, the quantity of the idle trailers is 1, the quantity of the idle trailers is not enough to meet the requirement, and the idle trailers can be moved to the target site according to the loading and unloading command.
In addition, because loading and unloading instruction quantity will be unnecessary idle trailer quantity, can also remain unnecessary loading and unloading instruction, guarantee that loading and unloading instruction quantity is equal with idle trailer quantity when the dispatch.
Step S302: and when the loading and unloading command quantity is not more than the idle trailer quantity, recording the loading and unloading command quantity as a target trailer quantity.
It should be noted that when the number of the loading and unloading commands is less than the number of the idle trailers, the number of the idle trailers that can be called is still vacant when the loading and unloading commands are met, and at this time, the number of the loading and unloading commands is taken as the target trailer number, and a corresponding number of trailers are selected through a preset trailer matching model to perform scheduling operation, for example: the loading and unloading instruction quantity is 1, the idle trailer quantity is 5, the idle trailer quantity is enough to meet the requirement, and the trailer with the minimum cost selected through the preset trailer matching model can be moved to the target place according to the loading and unloading instruction.
Further, in order to make all trailers in the yard available for effective use, after step S302, the method further includes:
and comparing the number of the idle trailers with the sum of the number of the target working trailers, and determining a trailer dispatching strategy according to the comparison result.
It can be understood that, when the vehicle is idle and each operating point all satisfies to be suitable for the dress to unload, need consider to utilize unnecessary idle trailer to carry out the yard arrangement this moment, send the car to the operation of moving the case, reduce the empty load of trailer and spend time. If all the working points meet the requirements of being suitable for loading and unloading, the following two conditions are adopted: 1. when the total quantity of the redundant idle trailers is smaller than the sum of the upper limit values of the trailers under each queue, respectively allocating one trailer to the shore bridge according to the priority sequence of the shore bridge, and if the idle trailers still exist, allocating all the trailers to a box-moving operation instruction so as to enable the idle trailers to perform box-moving operation; 2. and when the total number of the redundant idle trailers is not less than the sum of the upper limit values of the trailers under each queue, respectively adding the number of the trailers to each queue as the difference value between the upper limit value of the trailers in the queue and the currently allocated trailer, and if the idle trailers still exist, allocating all the trailers to the box-moving operation instruction.
It should be appreciated that the trailer dispatch strategy may be to determine the trailer to be allocated based on the number of empty trailers and allocate the trailer to be allocated based on the shore bridge priority information when the number of empty trailers is less than the sum of the target trailer numbers.
The embodiment discloses that when the loading and unloading command number is larger than the idle trailer number, the idle trailer number is recorded as a target trailer number; when the loading and unloading command quantity is not more than the idle trailer quantity, recording the loading and unloading command quantity as a target trailer quantity; this embodiment realizes accurate trailer distribution through the target trailer quantity of selecting different according to loading and unloading instruction quantity and idle trailer quantity, has improved the work efficiency to the trailer in the scene.
Referring to fig. 4, fig. 4 is a schematic flow chart illustrating a yard trailer dispatching method according to a third embodiment of the present invention.
Based on the second embodiment, in this embodiment, the step S40 includes:
step S401: and traversing the idle trailers in the yard to obtain the target idle trailer.
Step S402: and acquiring the matching evaluation factor of the target idle trailer, and determining the trailer weighted value corresponding to the target idle trailer according to the matching evaluation factor.
The matching evaluation factors include: at least one of a location parameter, a handling variation parameter, a queuing trailer parameter, a congestion parameter, and an instruction priority parameter, wherein the matching evaluation factor is used for data processing to obtain a trailer weighting value.
Step S403: and determining a matching cost matrix according to the matching evaluation factors and the trailer weighted value.
It can be understood that the matching cost matrix is used for quantifying the cost of the trailer to the target shore bridge, if the cost of the trailer to the target shore bridge is higher, the lower the working efficiency of the trailer is represented, correspondingly, if the cost of the trailer to the target shore bridge is lower, the higher the working efficiency is represented, and the matching cost matrix is comprehensively represented as: the system comprises a trailer and shore bridge position parameter, a loading and unloading mutual difference parameter, a queuing trailer number parameter, whether a target shore bridge is congested or not, an instruction priority parameter and the like.
Further, the step S403 includes:
carrying out data normalization processing on the matching evaluation factors to obtain a matching evaluation matrix;
determining a matching cost score of a target idle trailer according to the trailer weighted value and the matching evaluation matrix;
determining a matching cost score of a target idle trailer according to the trailer weighted value and the matching evaluation matrix;
generating a matching cost matrix based on the matching cost score;
and generating a matching cost matrix according to the trailer weighted value and the matching evaluation matrix.
It is understood that the matching evaluation matrix may be normalized by the position parameter, the handling-diversity parameter, the queuing trailer parameter, the congestion parameter, and the command priority parameter, respectively, for example: in the process of dispatching trailers, the obtained instruction is { I }1，I2，I3，...，InThe trailer is { T }1，T2，T3，...，TmSuppose for trailer T1Matching commands, n commands can be selected, and the distance between the current position of the trailer and the source position of the n commands is { d1，d2，d3，...，dn}; trailer T1The load and unload mutual difference index between the previous operation instruction and the n instructions is { f1，f2，f3，...，fnF is 0 if the mutual difference is equal to 0, otherwise f is equal to 1; number of queued trailers at work site for each order { q }1，q2，q3，...，qn}; congestion status of the yard column to which each instruction is directed { c1，c2，c3，...，cn}; the instruction class has a priority level of { p }1，p2，p3，...，pn}. Then, each factor is normalized, for example, the position factor, and after the normalization processing, the following steps are carried out:
the normalized processing of the loading and unloading parameters is as follows:
the parameters of the queue trailer are normalized as follows:
the normalization processing of the congestion parameters comprises the following steps:
after the instruction priority parameter is subjected to normalization processing, the instruction priority parameter comprises the following steps:
obtaining a matching evaluation matrix of the trailer T1 according to the position parameter, the loading and unloading diverse parameter, the queuing trailer parameter, the congestion parameter and the instruction priority parameter after the normalization processing:
the formula for generating the matching cost matrix according to the trailer weighted value and the matching evaluation matrix is as follows:
S1＝A*Q1＝{s1，s2，s3，...，sn}
wherein, A is the trailer weighted value, and Q1 is the matching evaluation matrix.
Step S404: and the matching cost matrix determines the target trailers corresponding to the target trailer number, and carries out scheduling operation on the target trailers according to the loading and unloading instruction.
