It should be understood that the specific implementation described herein is only used to illustrate and explain the embodiment of the present invention and is not used to limit the embodiment of the present invention.

[0033] Figure 1 The following schematically shows a flow chart of a method for factory logistics distribution in one embodiment of the present invention. Figure 1 As shown, in an embodiment of the present invention, a method for factory logistics distribution is provided. Taking the method applied to a processor as an example, the method may include the following steps:

[0034] Step S102 , obtaining material information of materials required for processing the workpiece to be produced at each workstation of the target production line, wherein the material information includes the material type and the material quantity corresponding to the material type.

[0035] Step S104 : determining the order information of the material delivery order corresponding to the workstation according to the pre-stored logistics delivery requirements and material information corresponding to the material types.

[0036] Step S106: Control the material delivery device to complete material delivery to the workstation according to the order information.

[0037] It can be understood that the target production line is a production line that needs to produce workpieces, and the target production line includes a plurality of workstations for processing. The workpieces to be produced are workpieces that need to be processed by each workstation, such as tires, vehicles, and the like. The materials required by each workstation can be the same or different, and the material information is information of materials required by each workstation for processing the workpieces to be produced, and can specifically include a material type and a material quantity corresponding to the material type, such as a bracket, a bent pipe, and the like. The logistics distribution demand corresponding to the material type can be determined and stored in advance, that is, the logistics distribution demand corresponding to the materials of different material types can be the same or different, and the logistics distribution demand of the material types in the same material distribution order is the same. The material distribution device is a device for transporting materials to the vicinity of each workstation of the production line, such as an AGV and the like. The AGV is a transport robot equipped with an electromagnetic or optical automatic guide device.

[0038] In some embodiments, the material distribution demand can include whether the material needs to be pre-batched, that is, the material of some material types needs to be pre-batched before distribution, and the material of some material types does not need to be pre-batched and can be directly distributed to the production line. Batch is the process of putting different types of materials into the same material distribution device. In other embodiments, the material distribution demand can include the type of material distribution device corresponding to the material type, that is, the type of material distribution device corresponding to the material of some material type is the same, and the type of material distribution device corresponding to the material of some material type is different. Further, the type of material distribution device can include the size type, model type of the material distribution device (such as AGV and the like), or the size type, model type of the material carrying device (such as a pallet) on the material distribution device. The order information of the material distribution order can include the order quantity, order content and the like of the material distribution order, and the order content can include information such as the specific material type on each material distribution order and the quantity corresponding to each specific material type. In addition, the order information can also include information of the material distribution device.

[0039] Specifically, the processor can obtain material information of the materials required for processing the workpiece to be produced at each workstation of the target production line. The material information is the material type and the material quantity corresponding to the material type required by each workstation to process the workpiece to be produced, wherein the number of workpieces to be produced can be one or more. Then, the processor can determine the order information of the material delivery order corresponding to the workstation based on the pre-stored logistics distribution requirements and material information corresponding to the material type, and control the material delivery device (e.g., AGV, etc.) according to the order information to deliver the materials required by each workstation to the corresponding workstation. The number of material delivery orders can be one or more. For example, when the material delivery requirement is the type of material delivery device corresponding to the material type, if there are a total of three material types in the material information of the materials required by a certain workstation, of which two material types have the same material delivery requirements and the material delivery requirement of another material type is different from the other two material types, then the order information of the corresponding material delivery order can be determined based on the material information corresponding to the two material types with the same material delivery requirements, and the order information of the corresponding material delivery order can be determined based on the material information of the other material type with different material delivery requirements. Furthermore, for example, when the total material quantity of two material types with the same material distribution requirements is less than a first preset threshold, the materials corresponding to the two material types with the same material distribution requirements and their material quantities are all included in one material distribution order; when the material quantity of another material type with different material distribution requirements is less than a second preset threshold, the materials corresponding to the other material type with different material distribution requirements and their material quantities are included in one material distribution order. The first preset threshold and the second preset threshold may be the same or different.

[0040] The above-mentioned method for factory logistics distribution obtains the material information of the materials required for processing the workpieces to be produced at each workstation of the target production line, and determines the order information of the material distribution order corresponding to the workstation based on the logistics distribution requirements and material information corresponding to the pre-stored material types, and then controls the material distribution device to complete the material distribution of the workstation according to the order information. The above-mentioned technical solution overcomes the disadvantages of the material distribution mode of manual material calling, and determines the order information of the material distribution order corresponding to each workstation in advance according to the material information and material distribution requirements of the materials required by each workstation, so that the material distribution device can be controlled according to the order information to complete the material distribution of each workstation, without the need for manual participation, which greatly reduces labor costs, avoids the problem of low accuracy in manual identification of material shortages, improves distribution efficiency, and can also realize real-time information transmission between the production line and the distribution department, further improving the production efficiency of the production line.

[0041] In an embodiment, the order information comprises an order quantity and an order content; and the determining of the material distribution order information corresponding to the work station according to the pre-stored logistics distribution demand corresponding to the material category and the material information comprises: determining that the logistics distribution demand corresponding to the material category is no need to mix, wherein the mixing is a process of putting different categories of materials into the same material distribution device; and determining the order quantity and the order content according to the material quantity and the maximum carrying quantity of the material distribution device carrying the material category.

[0042] It can be understood that the order information of the material distribution order can comprise an order quantity and an order content, and the order content can comprise information such as specific material categories on the material distribution order and the quantity corresponding to each specific material category. The mixing is a process of putting different categories of materials into the same material distribution device. Since the carrying space of the material distribution device is limited, a maximum carrying quantity of the material category that can be carried is usually set. The material category that does not need to be mixed is the material category that does not need to put different materials into the same material distribution device in advance and can be directly sent from the warehouse to the production line.

[0043] Specifically, when the processor determines that the logistics distribution demand corresponding to the material category is no need to mix, the processor can determine the order quantity and the order content of the material distribution order according to the material quantity corresponding to the material category and the maximum carrying quantity of the material distribution device carrying the material of the material category. For example, if the material quantity corresponding to the material category A is 8 and the maximum carrying quantity of the material distribution device carrying the material of the material category A is 5, the order quantity of the material distribution order can be determined as 2, and the order content of the material distribution order is 5 pieces of material category A and 3 pieces of material category A, respectively.

[0044] In the embodiments of the present application, when the logistics distribution demand corresponding to the material category is no need to mix, the order quantity and the order content can be directly determined according to the material quantity and the maximum carrying quantity of the material distribution device carrying the material category, the determination time of the material distribution order is shortened, the maximum utilization of the loading space of the material distribution device is realized, and the distribution efficiency is maximized.

[0045] In an embodiment, the order information comprises an order quantity and an order content; and the determining of the material distribution order information corresponding to the work station according to the pre-stored logistics distribution demand corresponding to the material category and the material information comprises: determining that the logistics distribution demand corresponding to the material category is no need to mix, wherein the mixing is a process of putting different categories of materials into the same material distribution device; and determining the order quantity and the order content according to the pre-set material mixing rule, the material category and the material quantity, wherein the material mixing rule comprises a mixed material category and a quantity corresponding to each mixed material category.

[0046] It can be understood that the preset material combination rule is a combination of materials placed in the same material distribution device in advance, including the combination of material types and the corresponding number of each material type, for example, the combination of 3 materials B, 3 materials C and 2 materials D, or the combination of 4 materials B and 2 materials C, etc. Further, the preset material combination rule can also include the type of material distribution device, that is, the corresponding combination of material types and the corresponding number of each material type of different material distribution devices can be different, for example, the material combination rule corresponding to the material distribution device M can be the combination of 3 materials B, 3 materials C and 2 materials D, and the material combination rule corresponding to the material distribution device N can be the combination of 4 materials B and 2 materials C.

[0047] Specifically, when the processor determines that the logistics distribution demand corresponding to the material type is to be combined, the order quantity and order content of the material distribution order can be determined according to the material type and the number of materials required by the station based on the preset material combination rule, for example, the material type required by the station includes material B and material C, the preset material combination rule includes the combination of 4 materials B and 2 materials C, the number of materials B is 6, and the number of materials C is 4, then the order quantity of the material distribution order can be determined as 2, and the order content of the material distribution order is 4 materials B and 2 materials C, 2 materials B and 2 materials C. In addition, the order content can also include the type of material distribution device, that is, the corresponding material combination rule of different types of material distribution devices can be different, and the corresponding material combination rule of the same type of material distribution device is usually the same.

[0048] In the embodiments of the present application, when the logistics distribution demand corresponding to the material type is to be combined, the order quantity and order content are determined according to the preset material combination rule, the material type and the number of materials, which shortens the determination time of the material distribution order, realizes the full use of the loading space of the material distribution device, and maximizes the distribution efficiency.

[0049] In one embodiment, the material distribution device is controlled to complete the material distribution of the station according to the order information, including: determining the start distribution time of the material distribution order; and controlling the material distribution device to complete the material distribution of the station according to the start distribution time and the order information.

[0050] It can be understood that the start distribution time is the time when the material distribution device starts to distribute the material to the station.

[0051] Specifically, the processor can determine the start time of a material delivery order, such as starting delivery at 7:00 a.m., and then control the material delivery device to complete material delivery to the workstation based on the start time and specific order information. Furthermore, when there are a large number of material delivery orders, each material delivery order can be controlled to start delivery at a preset interval. For example, if the start time of the first material delivery order is 7:00 a.m., the start time of the second material delivery order is 20 minutes after the start time of the first material delivery order, that is, delivery starts at 7:20 a.m. The specific interval length can be determined based on the specific work efficiency or work progress of the workstation.

[0052] In one embodiment, there are multiple material delivery orders, and determining the start delivery time of the material delivery orders includes: determining the order of multiple material delivery orders; determining the start delivery time of the material delivery order in the first priority according to the preset start production time of the workpiece to be produced and the preset delivery time of the material delivery device; obtaining the order content of the first priority material delivery order, wherein the order content includes the quantity of delivered materials; determining the delivery interval duration according to the preset processing time for processing a single workpiece to be produced at the workstation, the quantity of delivered materials, and the total quantity of materials required for the workstation to process a single workpiece to be produced; determining the start delivery time of the material delivery order in the second priority according to the start delivery time and delivery interval duration of the first priority material delivery order.

[0053] It can be understood that the preset start time of production of the workpiece to be produced is the preset start time of production of the workpiece to be produced, such as 8 am. The preset delivery time of the material distribution device is the predetermined time for the material distribution device to deliver the material from the warehouse to the production line, such as 30 minutes. The preset processing time for a workstation to process a single workpiece to be produced is the length of time it takes for the workstation to process a single workpiece to be produced, such as 10 hours. The quantity of delivered materials is the total quantity of materials delivered in each material delivery order. The delivery interval is the length of time between the start time of the current material delivery order and the start time of the previous material delivery order.

[0054] Specifically, when there are multiple material delivery orders, the processor may first determine the order of the multiple material delivery orders. The specific order may be determined based on, for example, the distance between the specific location of the materials in the warehouse and the production line. Furthermore, the processor may determine the start time of the material delivery order with the highest priority based on the preset production start time of the workpiece to be produced and the preset delivery duration of the material delivery device. For example, when the preset production start time is 8:00 and the preset delivery duration is 30 minutes, the start time of the material delivery order with the highest priority may be determined to be 7:30. Furthermore, the processor can obtain the order content (including the quantity of delivered materials) of the first-priority material delivery order, and thereby determine the delivery interval between the second-priority material delivery order and the first-priority material delivery order based on the preset processing time for processing a single workpiece to be produced at the workstation, the quantity of delivered materials, and the total quantity of materials required for processing a single workpiece to be produced at the workstation. For example, the delivery interval can be determined based on a predetermined algorithm using these three values ​​as inputs to the algorithm. The delivery interval can be proportional to the preset processing time for processing a single workpiece to be produced at the workstation and the quantity of delivered materials in the previous material delivery order, and inversely proportional to the total quantity of materials required for processing a single workpiece to be produced at the workstation. Thus, the processor can determine the start delivery time of the second-priority material delivery order based on the start delivery time and the delivery interval. That is, by adding the delivery interval to the start delivery time of the first-priority material delivery order, the start delivery time of the second-priority material delivery order can be obtained. This is repeated in this manner until the start delivery times of all material delivery orders are determined.

[0055] In an embodiment of the present application, the determination of the start delivery time of the material delivery order of the current priority is related to the start delivery time of the material delivery order of the previous priority, the quantity of delivery materials of the material delivery order of the previous priority, the preset processing time for the work station to process a single workpiece to be produced, and the total quantity of materials required for the work station to process a single workpiece to be produced. The embodiment of the present application can accurately determine the start delivery time of each material delivery order according to the processing progress of the work station, thereby improving the work efficiency of the production line.

[0056] In some embodiments, the calculation of the start delivery time may also take into account the production lead time. That is, if there is a production lead time, it is necessary to subtract the production lead time from the start delivery time determined in the above embodiments, so as to flexibly determine the start delivery time in combination with the actual application scenario to meet the different needs of the actual production scenario.

[0057] In one embodiment, the delivery interval duration is determined based on the preset processing time for processing a single workpiece to be produced at the workstation, the quantity of delivered materials, and the total quantity of materials required for processing a single workpiece to be produced at the workstation, including: determining the ratio of the quantity of delivered materials to the total quantity of materials; determining the product value of the preset processing time and the ratio to obtain the delivery interval duration.

[0058] Specifically, the processor can first determine the ratio of the quantity of delivered materials of the first-priority material delivery order to the total quantity of materials required for the workstation to process a single workpiece to be produced, and thus determine the product value of the preset processing time for the workstation to process a single workpiece to be produced and the ratio, so as to obtain the delivery interval duration between the second-priority material delivery order and the first-priority material delivery order.

[0059] In the embodiment of the present application, the delivery interval duration is determined by a precise formula algorithm, which can improve the real-time performance of information transmission between the production line and the delivery department.

[0060] In one embodiment, before controlling the material delivery device to complete material delivery to the workstation according to the order information, the method further includes: determining a material consolidation start time corresponding to the material delivery order; and controlling the consolidation of materials corresponding to the material delivery order according to the material consolidation start time.

[0061] It is understandable that when materials need to be combined, the starting time of the material combination needs to be determined in advance. The starting time of the material combination is the time when different types of materials begin to be combined.

[0062] Specifically, the processor can determine the material consolidation start time corresponding to the material delivery order. For example, the material consolidation start time can be determined to be 3 days or 1 day before the current time when the material delivery order is determined or the preset start time of production of the workpiece to be produced. Then, the materials corresponding to the material delivery order can be controlled to be consolidated according to the material consolidation start time. Furthermore, when the number of material delivery orders is large, each material delivery order can be controlled to start consolidation according to a preset interval. For example, the material consolidation start time of the first material delivery order is 7 a.m., and the interval between the material consolidation start time of the second material delivery order and the material consolidation start time of the first material delivery order is 30 minutes, that is, the consolidation starts at 7:30 a.m. The specific interval can be determined according to the actual scenario.

[0063] In one embodiment, the number of material delivery orders is multiple, and the material binning start time corresponding to the material delivery order is determined by: determining the order of the multiple material delivery orders; determining that the material binning start time corresponding to the material delivery order at the first order is a time point before the preset start production time of the to-be-produced workpiece and interval a preset time period; obtaining the order content of the material delivery order at the first order, wherein the order content includes the delivery material quantity; determining the binning interval time according to the preset processing time of the workpiece processing a single to-be-produced workpiece, the delivery material quantity, and the total material quantity of the material required by the workpiece processing a single to-be-produced workpiece; and determining the material binning start time of the material delivery order at the second order according to the material binning start time corresponding to the material delivery order at the first order and the binning interval time.

[0064] It can be understood that the preset time period is a pre-set time period, for example, 12 hours or 24 hours, etc. The binning interval time is the interval time length between the material binning start time of the current order material delivery order and the material binning start time of the last order material delivery order.

[0065] Specifically, when there are multiple material delivery orders, the processor may first determine the order of the multiple material delivery orders. The specific order may be determined based on, for example, the distance between the specific location of the materials in the warehouse and the production line. Furthermore, the processor may determine that the material consolidation start time corresponding to the first-priority material delivery order is a time that is before the preset production start time of the workpiece to be produced and within a preset time period. For example, when the preset production start time is 8:00 a.m. tomorrow and the preset time period is 24 hours, the processor may determine that 8:00 a.m. today is the material consolidation start time corresponding to the first-priority material delivery order. Furthermore, the processor can obtain the order content (including the quantity of delivered materials) of the first-priority material delivery order, and thereby determine the combined interval duration between the second-priority material delivery order and the first-priority material delivery order based on the preset processing time for processing a single workpiece to be produced at the workstation, the quantity of delivered materials, and the total quantity of materials required for processing a single workpiece to be produced at the workstation. For example, based on a predetermined algorithm, the three values ​​can be used as input quantities of the algorithm to determine the combined interval duration, wherein the combined interval duration can be directly proportional to the preset processing time for processing a single workpiece to be produced at the workstation and the quantity of delivered materials of the previous material delivery order, and inversely proportional to the total quantity of materials required for processing a single workpiece to be produced at the workstation. Therefore, the processor can determine the material consolidation start time of the second-priority material delivery order based on the material consolidation start time and the delivery interval duration of the first-priority material delivery order, that is, add the delivery interval duration to the material consolidation start time of the first-priority material delivery order to obtain the material consolidation start time of the second-priority material delivery order, and so on, until the material consolidation start time of all material delivery orders is determined.

[0066] In an embodiment of the present application, the determination of the material consolidation start time of the material delivery order of the current priority is related to the material consolidation start time of the material delivery order of the previous priority, the quantity of delivered materials of the material delivery order of the previous priority, the preset processing time for the work station to process a single workpiece to be produced, and the total quantity of materials required for the work station to process a single workpiece to be produced. The embodiment of the present application can determine the material consolidation start time of each material delivery order according to the processing progress of the work station, thereby improving production efficiency.

[0067] In some embodiments, the calculation of the material consolidation start time may also take into account the production lead time. That is, if there is a production lead time, it is necessary to subtract the production lead time from the material consolidation start time determined in the above embodiment, so as to flexibly determine the material consolidation start time in combination with the actual application scenario to meet the different needs of the actual production scenario.

[0068] In one embodiment, the interval duration is determined according to a preset processing duration of a single to-be-produced workpiece processed by the work station, a quantity of the distributed materials, and a total quantity of the materials required by the single to-be-produced workpiece processed by the work station, and includes: determining a ratio of the quantity of the distributed materials to the total quantity of the materials; and determining a product value of the preset processing duration and the ratio to obtain the interval duration.

[0069] Specifically, the processor can first determine a ratio of a quantity of distributed materials of a material distribution order in a first order to a total quantity of materials required by a single to-be-produced workpiece processed by the work station, and then determine a product value of a preset processing duration of the single to-be-produced workpiece processed by the work station and the ratio, so as to obtain the interval duration between the material distribution order in the second order and the material distribution order in the first order.

[0070] In the embodiments of the present application, the interval duration is determined by a precise formula algorithm, and the interval duration can be accurately determined.

[0071] In one embodiment, the material information of the materials required by the work station of the target production line for processing the to-be-produced workpiece is obtained, and includes: obtaining workpiece information of a plurality of to-be-produced workpieces produced by the target production line in a preset period, wherein the workpiece information includes a workpiece type of the to-be-produced workpiece; classifying the plurality of to-be-produced workpieces according to the workpiece type to obtain a plurality of classified to-be-produced workpiece sets, wherein the to-be-produced workpieces in the to-be-produced workpiece set have the same workpiece type; and obtaining the material information of the materials required by the work station of the target production line for processing the to-be-produced workpiece set.

[0072] It can be understood that the preset period is a pre-set production period, for example, one day or three days, etc. The to-be-produced workpiece set is a set or group of to-be-produced workpieces of the same workpiece type. The workpiece information can include the workpiece type, and in addition, can include a workpiece quantity corresponding to the workpiece type.

[0073] Specifically, when the quantity of the to-be-produced workpieces is a plurality and the workpiece types are inconsistent, the processor can obtain workpiece information (including the workpiece type) of a plurality of to-be-produced workpieces produced by the target production line in a preset period (for example, within 1 day), and then can classify the plurality of to-be-produced workpieces according to the workpiece type to obtain a plurality of classified to-be-produced workpiece sets including the same workpiece type, so as to obtain the material information of the materials required by the work station of the target production line for processing the to-be-produced workpiece set.

[0074] In the embodiments of the present application, by obtaining the workpiece information of a plurality of to-be-produced workpieces produced by the target production line in a preset period, the plurality of to-be-produced workpieces are classified according to the workpiece information, so as to obtain the material information of the materials required by each type of to-be-produced workpiece, so as to subsequently perform material distribution of the work station for each type of to-be-produced workpiece, and improve the production efficiency.

[0075] In existing technology, due to the limited area along the production line in the workshop, only a portion of the starting materials are delivered to the lineside workstations when the production line is about to start production. During the production process, when the materials are insufficient, manual material orders are made, and the missing materials and quantities are manually identified and compiled into a material order list. This traditional material distribution model lacks real-time information transmission between the production line and the distribution department, and cannot meet the lean production needs of enterprises to improve quality, reduce costs and increase efficiency. The shortcomings of existing technology include: 1) Manual material orders lead to increased labor costs, and the manually counted data may contain errors, and the distribution efficiency is low; 2) The accumulation of materials distributed along the line. When multiple products are produced on the same line, the variety and quantity of materials are large, which easily leads to the accumulation of materials along the line.

[0076] The core basis of the specific technical solution provided by the embodiment of the present invention can be a file that records the detailed plan of each part in the production process, such as a PFEP file. This file records key data such as the materials and quantities required for each production station of a single product in the production process, the delivery rhythm, etc., and cooperates with the daily sorted production work orders issued by the manufacturing execution system to calculate all the sorted material delivery orders for the production work orders of the day. Combined with the automated scheduling of AGV equipment, the automation of material distribution in the production workshop can be realized, and at the same time, the timely and accurate delivery of materials can be guaranteed.

[0077] The equipment support required for the specific technical solution provided by the embodiment of the present invention may include but is not limited to: 1. Handheld PDA that supports barcode scanning and data entry; 2. AGV that supports the transportation of various types of regular materials; 3. IT system server, IT system (such as MES (Manufacturing Execution System) / LES (Logistics Execution System)) provides the basic data maintenance required for this technical solution. At the same time, the system calculates the material delivery order regularly in the background based on the maintained basic information, and schedules the AGV for delivery according to the delivery time of the material delivery order.

[0078] The specific technical solution process can be as follows (for details, please refer to Figure 2 and Figure 3 shown):

[0079] 1. Basic Data Maintenance: Maintained basic data may include workshops, production lines, workstations, delivery points, PFEP documents, production work orders, and distribution rules. Workshops, production lines, workstations, and production work orders can be obtained from the Manufacturing Execution System (MES). Distribution points, PFEP documents, and distribution rules can be maintained in the Logistics Execution System (LES).

[0080] 2. Order pre-processing: Based on the maintained basic data and the production work orders of the day that have been sorted by MES, all the sorted material delivery orders for each workstation on the day are generated according to the rules.

[0081] 1) According to the production order issued by MES, the production lines are grouped and sorted according to the production line when the order is arranged, each order has a production sequence, and the production materials are also distributed according to the sequence of the sorted order.

[0082] 2) According to the PFEP file information of the product (i.e. the workpiece to be produced), the orders are summarized according to the single production line, and all the material information required for the production of each station on this production line is obtained, and each station material is processed separately according to different distribution requirements:

[0083] a. The materials of the warehouse direct delivery production line are disassembled according to the maximum material quantity carried by the distribution tray maintained in the PFEP file, and the materials are disassembled into n material requisition orders (i.e. material distribution orders), and the material requisition orders are sorted, and the material release time Hs of the sorted material requisition orders is calculated.

[0084] b. The materials that need to be combined (multiple types of materials combined into one tray) are disassembled into n material requisition orders according to the material types and quantities defined by the combination rules, and the material requisition orders are sorted, and the material release time Hs and the combination time Hp of the material requisition orders are calculated.

[0085] The material combination needs to be performed in advance, i.e. the material combination is completed before the production call, and the combination time can be set to the day before the scheduled online time of the production order. Taking the n sorted material requisition orders disassembled from a single station as an example:

[0086] The calculation rule of the material combination start time corresponding to the material requisition order can be as follows:

[0087] The material combination start time Hp1 of the material requisition order with the order 1: Hp1 = sysdate-Hs, where sysdate is the current time when the order is preprocessed by the system, and Hs is the production lead time, which can be flexibly configured according to the actual production situation.

[0088] The material combination start time of the material requisition order with the order 2 can be accumulated according to the material combination start time of the previous material requisition order according to the formula, and the material combination start time of the material requisition order with other orders can be calculated according to the same logic as the material requisition order with the order 2, and the calculation formula can be as follows:

[0089]

[0090] Where S is the total time required for producing a single product at a single station (i.e. the preset processing time, such as 10h), N S is the number of materials required in the previous material requisition order, for example, the maximum number of materials that can be carried by a single material distribution device (such as 5), N d is the total number of materials required for producing a single product at a single station (such as 10), and H P1Hm is the material pool start time of the last material requisition (the material requisition with order 1), H P2 Hm is the material pool start time of the material requisition with order 2.

[0091] The calculation rule of the material release time (i.e. the start distribution time) of the material requisition can be as follows:

[0092] The material release time Hs1 of the material requisition with order 1 is Hm-Hn-Hs.

[0093] Hm is the scheduled online time corresponding to the work order with order 1, i.e. the predicted start production time of the work order, Hn is the total time consumed by AGV from warehouse distribution to production line station, which can be maintained in the PFEP file, and Hs is the production lead time, which can be flexibly configured according to the actual production situation.

[0094] The material release time of the material requisition with order 2 is accumulated according to the formula based on the material release time of the last material requisition, and the calculation logic of the material release time of the material requisition with other orders is the same as that of the material requisition with order 2, and the calculation formula can be as follows:

[0095]

[0096] S is the total time required for a single station to produce a single product (i.e. the preset processing time, such as 10h), N S is the number of materials required in the last material requisition (such as 5), N d is the total number of materials required for producing a single set of products (such as 10), H S1 Hm is the material release time of the last material requisition (the material requisition with order 1), H S2 Hm is the material release time of the material requisition with order 2.

[0097] After the required materials of each station are split into n material requisitions, all ordered material requisitions of the production work order of the day can be obtained, as shown in Figure 3 .

[0098] III. Production distribution: The production distribution mode is a combination of pull and push distribution modes.

[0099] 1. After all the material requisitions required by the stations of the production line on the day are generated in order, the logistics execution system will periodically poll the material release time of the material requisition. As long as the material release time is due, the logistics execution system will automatically generate AGV scheduling instructions to automatically distribute materials to the production line side.

[0100] 2. If the worker takes the materials on the line side during the production process and scans the empty tray with the PDA (handheld mobile device supporting mobile scanning), it will automatically determine whether to replenish a tray of the same materials.

[0101] Compared with the traditional material distribution model, the specific technical solution provided by the embodiment of the present invention combines material distribution devices such as automated equipment AGV to realize the automatic splitting and ordering of material requirements. The upstream manufacturing execution system only needs to issue production work orders, and the logistics execution system automatically processes the documents according to the issued work orders, and automatically splits them into N small orders according to the production rhythm, and assigns a delivery time to the order. The AGV only needs to deliver them regularly according to this time. This solution not only saves labor costs, but also ensures the accuracy and timeliness of material distribution, and provides support for the digitalization and intelligence of enterprises. Order preprocessing based on PFEP files subdivides the materials required for production into material requisition orders sorted by time. All distribution rules rely on PFEP data, and the accuracy of PFEP data must be guaranteed.
