For example, the "first time period" can be described as the "second time period", and similarly, the "second time period" can be described as the "first time period".

[0067] The workshop replenishment method provided in the embodiment of the present application can be applied to Figure 1In the application environment shown. Among them, the server 102 communicates with the supply unit device 104 through the network, and the server 102 also communicates with the material transportation tool 106 through the network. The data storage system can store the data that the server 102 needs to process. The data storage system can be integrated on the server 102, or it can be placed on the cloud or other network servers. The server 102 obtains the workshop production plan and the vehicle assembly progress, and determines the first supply demand information according to the workshop production plan and the vehicle assembly progress. It also obtains the first time period required for the vehicle assembly progress to reach the target assembly station, and the second time period required for material transportation, and determines the first arrival time according to the first time period and the second time period. Then the server 102 can generate a first replenishment document according to the first supply demand information and the first arrival time, and send the first replenishment document to the supply unit device 104 to instruct the supply unit to transport the material. When the material is transported to the factory, the server 102 receives the target material by verifying the truck information loaded with the target material, and triggers the storage of the received target material in the material cache area. The logistics personnel store the target material in the material cache area according to the instructions. Finally, when the on-line triggering opportunity is reached, the server sends an on-line instruction to the material transport tool 106 to instruct the material transport tool 106 to transport the target material in the buffer area to the production line.

[0068] The supply unit device 104 may be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, IoT devices, and portable wearable devices. The server 102 may be implemented as an independent server or a server cluster consisting of multiple servers.

[0069] In one embodiment, the server 102 is integrated with a MOM system (Manufacturing Operations Management), a LES system (Logistics Execution System), and an ETCP system (Electronic Traffic Control Panel). The MOM system obtains the workshop production plan and the vehicle assembly progress, and sends the obtained workshop production plan and vehicle assembly progress to the LES system. The LES system determines the first supply demand information based on the workshop production plan and the vehicle assembly progress. The LES system also determines the first arrival time based on the first time period required for the vehicle assembly progress to reach the target assembly station and the second time period required for material transportation, and based on the first time period and the second time period. Furthermore, the LES system can generate a first replenishment document based on the first supply demand information and the first arrival time, and send the first replenishment document to the supply unit equipment to instruct the supply unit to transport the materials. When the materials are transported to the factory, the ETCP system receives the target materials by verifying the information of the trucks loaded with the target materials, and feeds back the material acceptance status to the LES system. The LES system triggers the storage of the received target materials in the material buffer area, and the logistics personnel store the target materials in the material buffer area according to the instructions. Finally, when the online triggering time is reached, the LES system sends an online instruction to the material transport tool to instruct the material transport tool to transport the target materials in the buffer area to the production line.

[0070] In one embodiment, Figure 2 As shown, a workshop replenishment method is provided, which is applied to Figure 1 The server in the example is used to illustrate the following steps:

[0071] Step 202: Obtain the workshop production plan and the vehicle assembly progress, and determine the first supply demand information according to the workshop production plan and the vehicle assembly progress.

[0072] Among them, the workshop production plan is a comprehensive arrangement of the workshop production tasks. The workshop carries out production work according to the production plan. The production plan contains information such as the planned material requirements for production, the material supply sequence, and the material replacement plan. The vehicle assembly progress is the progress of assembling the vehicles to be assembled. The first supply demand information is the material demand information that needs to be provided by the supplier, which generally includes the type and quantity of materials, the consumption sequence of each material, the equipment allocation method of the material, the equipment sequence, the delivery logistics gate, the receiving buffer area, and the estimated consumption time of parts.

[0073] Specifically, after the server obtains the workshop production plan and the vehicle assembly progress, the server may determine the first supply demand information according to the workshop production plan and the vehicle assembly progress, which may specifically include the type and quantity of materials required to be provided by the supplier.

[0074] In one of the embodiments, the first supply demand information is determined according to the workshop production plan and the vehicle assembly progress, including: determining the order trigger station in the production line, and when the vehicle assembly progress reaches the order trigger station, calculating the material information of the target material required for each target assembly station in sequence according to the workshop production plan, until it is determined that the stop condition is met according to the material information obtained by the sequential calculation, and the first supply demand information is obtained.

[0075] Among them, the order trigger station is the station that starts to count the material demand information on the production line. When the assembly progress of the vehicle to be assembled reaches the order trigger station, the server starts to count the material demand information on the production line and then generates a demand document. Therefore, the station that starts to count the material demand information on the production line is called the order trigger station. The target assembly station is the station with replenishment demand, and the material that needs to be replenished at the target assembly station is the target material.

[0076] Specifically, when determining the first supply demand information, the server needs to determine the order triggering station in the production line. Optionally, the server can determine the position number of the order triggering station in the production line according to the position number of the first target assembly station and the ratio of the time required for the vehicle to be assembled to move from the order starting position to the first target assembly station to the production rhythm. Among them, the production rhythm is the time required for a station to complete the assembly of the vehicle to be assembled. The difference between the position number of the order starting position and the position number of the first target assembly station can be determined by the ratio of the time required for the vehicle to be assembled to move from the order starting position to the first target assembly station to the production rhythm. Furthermore, when the assembly progress of the vehicle to be assembled reaches the order triggering station, the server calculates the material information of the target materials required by each target assembly station respectively according to the workshop production plan, until it stops when it is determined that the stop condition is reached according to the material information obtained by sequential calculation, and obtains the first supply demand information. Optionally, the accumulation can be stopped when the number of materials obtained by sequential calculation reaches the maximum number of accumulated parts. The maximum cumulative number of parts is the maximum number of parts that a device can load, and the time it takes for the material quantity to reach the maximum cumulative number of parts is the maximum cumulative time.

[0077] It should be noted that the production line can assemble vehicles of different models, and the materials required for assembling different models at the same workstation are different. Therefore, in the process of calculating the target materials in sequence, for materials that are not required for every model at the same workstation, the material information can be skipped according to the model of the current vehicle to be assembled.

[0078] In this embodiment, by determining the order trigger station in the production line, and then when the vehicle assembly progress reaches the order trigger station, the material information of the target material required for each target assembly station is calculated in sequence according to the workshop production plan, until it is determined that the stop condition is met according to the material information calculated in sequence, and the first supply demand information is obtained, thereby realizing the determination of the supply demand from the production line as the demand side, thereby improving the efficiency of replenishing the workshop.

[0079] Step 204 , obtaining a first time period required for the vehicle assembly progress to reach the target assembly station and a second time period required for material transportation, and determining a first arrival time according to the first time period and the second time period.

[0080] Among them, the first time period is the time when the assembly progress of the vehicle to be assembled reaches the target assembly station that needs to be replenished, the second time period is the time required for the target material to be transported from the supplier to the factory, and the first arrival time is the time when the target material arrives at the factory.

[0081] Specifically, the server obtains the first time period required for the vehicle to be assembled to reach the target assembly station and the second time period required for the material to be transported from the supplier to the factory, and then performs a difference processing on the first time period and the second time period to determine the time when the target material arrives at the factory.

[0082] In one of the embodiments, a first time period required for the vehicle assembly progress to reach a target assembly station and a second time period required for material transportation are obtained, and a first arrival time is determined based on the first time period and the second time period, including: obtaining a target time point for the vehicle to be assembled to pass through the sequencing station; determining a first position number corresponding to the sequencing station, a second position number corresponding to the first target assembly station in the production line, and a production rhythm; determining a first time period required for the vehicle assembly progress to reach the first target assembly station based on the target time point, the first position number, the second position number, and the production rhythm; obtaining the second time period required for material transportation, and determining the first arrival time based on the difference between the first time period and the second time period.

[0083] The sequencing station is a station used to determine the assembly sequence of the vehicles to be assembled, and the first target assembly station is the first station with replenishment demand.

[0084] Specifically, after obtaining the target time point of the vehicle to be assembled passing through the sequencing station, the server determines the first position number corresponding to the sequencing station, the second position number corresponding to the first target assembly station in the production line, and the production rhythm, and then processes the target time point of passing through the sequencing station, the position number corresponding to the sequencing station, and the position number corresponding to the first target assembly station in the production line to determine the first time period required for the assembly progress of the vehicle to be assembled to reach the first target assembly station. In addition, the server also obtains the second time period required for the material to be transported from the supplier to the factory, and then the server subtracts the second time period required for the material to be transported from the supplier to the factory from the first time period required for the vehicle to be assembled to reach the target assembly station to obtain the first arrival time.

[0085] In one of the embodiments, if there is a break time in the first time period for the vehicle to be assembled to arrive at the target assembly station on the work calendar, then after deducting the second time period required for the material to be transported from the supplier to the factory from the first time period required for the vehicle to be assembled to arrive at the target assembly station, the break time needs to be deducted to obtain the first arrival time.

[0086] In one of the embodiments, a first time period required for the vehicle assembly progress to reach the first target assembly station is determined based on the target time point, the first position number, the second position number, and the production rhythm, including: multiplying the difference between the first position number and the second position number by the production rhythm to obtain a corresponding product, and determining the first time period required for the vehicle assembly progress to reach the target assembly station based on the sum of the target time point and the product.

[0087] Specifically, the server obtains the target time point when the vehicle to be assembled passes through the sequencing station, and determines the first position number corresponding to the sequencing station, the second position number corresponding to the first target assembly station in the production line, and the production rhythm, then subtracts the first position number from the second position number to obtain the difference between the first position number and the second position number, multiplies the difference between the first position number and the second position number by the production rhythm to obtain a corresponding product, and then sums the product with the target time point to determine the first time period required for the vehicle assembly progress to reach the first target assembly station.

[0088] In one embodiment, if there is a rest time in the process of moving the vehicle to be assembled from the sequencing station to the first target assembly station on the work calendar, it is necessary to sum the difference between the first position serial number and the second position serial number, the product of the production cycle, the target time point and the rest time, and then the computer device can determine the first time period required for the vehicle assembly progress to reach the first target assembly station according to formula (1):

[0089] T 1 =T 0+(N 定序 -N 装配 )*t 节拍 +T 休息补偿 (1)

[0090] Among them, T 1 The first time period required for the vehicle assembly progress to reach the first target assembly station; T 0 N is the time for the vehicle to be assembled to pass through the sequencing station; 定序 N is the position number of the sequencing station; 装配 is the position number corresponding to the first target assembly station in the production line, t beat is the production beat, T 休息补偿 It is the rest time during the process of moving the vehicle to be assembled from the sequencing station to the first target assembly station on the work calendar.

[0091] Then the first arrival time can be determined according to formula (2):

[0092] T 到货 =T 1 -(T 配送 +T 缓存 )-T 休息补偿 (2)

[0093] Among them, T 到货 is the first arrival time; T 配送 It is the time required to deliver materials from the supplier to the factory gate; T 缓存 It is the storage time of materials in the material buffer area within the factory.

[0094] It should be noted that N 定序 ,t 节拍 , T 休息补偿 , T 配送 , T 缓存 These are the parameters pre-set in the LES system.

[0095] In the above embodiment, the server obtains the target time point when the vehicle to be assembled passes through the sequencing station, and determines the first position number corresponding to the sequencing station, the second position number corresponding to the first target assembly station in the production line, and the production rhythm, and then determines the first time period required for the vehicle assembly progress to reach the first target assembly station according to the target time point, the first position number, the second position number, and the production rhythm, and obtains the second time period required for material transportation, and then determines the first arrival time according to the difference between the first time period and the second time period. In this way, the production line can make clear instructions on the supply time as the demand side, thereby improving the efficiency of replenishing the workshop.

[0096] Step 206: Generate a first replenishment document according to the first supply demand information and the first arrival time, and send the first replenishment document to the supply unit to instruct the supply unit to transport the materials.

[0097] Among them, the replenishment document is a document sent to the supplier, and the supplier replenishes the goods according to the supply demand information and arrival time instructions on the replenishment document. It should be noted that the supplier can be a short-distance supplier close to the factory, a warehouse outside the factory for storing materials, or another sister factory that stores the target materials. Generally speaking, the time required for the supplier to transport the target materials to the factory by truck is usually measured in hours.

[0098] Specifically, after determining the first supply demand information and the first arrival time, the server generates a first replenishment document according to the first supply demand information and the first arrival time, and then sends the first replenishment document to the supply unit to instruct the supply unit to transport the material. The first replenishment document records the first supply demand information and the first arrival time, and then the replenishment unit can replenish the goods according to the first supply demand information and the first arrival time recorded on the first replenishment document.

[0099] Step 208, receiving the target material when the material is transported to the factory, and triggering the storage of the received target material into the material buffer area.

[0100] Among them, the material buffer area is an area within the factory used to temporarily store materials before they go online.

[0101] Specifically, when the supply unit transports the materials to the factory according to the first replenishment document, the server receives the target materials by verifying the license plate information of the truck loaded with the materials, and triggers the storage of the received target materials into the material cache area.

[0102] Step 210, when the on-line triggering opportunity is reached, an on-line instruction is sent to the material transportation tool to instruct the material transportation tool to transport the target material in the buffer area to the production line.

[0103] The on-line triggering timing is when the assembly progress of the vehicle to be assembled reaches a specific station, the server will send an on-line instruction to the material transport tool, the specific station is the on-line triggering station, and the timing when the assembly progress of the vehicle to be assembled reaches the on-line triggering station is the on-line triggering timing. The on-line instruction is an instruction to instruct the material transport tool to transport the target material in the buffer area to the production line.

[0104] Specifically, after the server triggers the storage of the received target material into the material cache area, the target material is temporarily stored in the material cache area waiting to go online. When the server obtains that the assembly progress of the vehicle to be assembled reaches the online triggering station, the server sends an online instruction to the material transport tool to instruct the material transport tool to transport the target material in the cache area to the production line. The material transport tool transports the target material in the cache area to the production line according to the online instruction. It should be noted that the material transport tool can be an AGV (Automated Guided Vehicle) or other transport tools such as transport robots.

[0105] The above-mentioned workshop replenishment method obtains the workshop production plan and the vehicle assembly progress, and determines the first supply demand information according to the workshop production plan and the vehicle assembly progress; obtains the first time period required for the vehicle assembly progress to reach the target assembly station, and the second time period required for material transportation, and determines the first arrival time according to the first time period and the second time period; then generates a first replenishment document according to the first supply demand information and the first arrival time, and sends the first replenishment document to the supplier to instruct the supplier to transport the materials; receives the target materials when the materials are transported to the factory, and triggers the storage of the received target materials in the material cache area; finally, sends an online instruction to the material transportation tool when the online trigger timing is reached, to instruct the material transportation tool to transport the target materials in the cache area to the production line, so that the time for replenishing the workshop can be accurately controlled, thereby improving the efficiency of workshop replenishment.

[0106] In one of the embodiments, when the materials are transported to the factory, the target materials are received, including: receiving the binding information of the truck and the target materials sent by the supplier; determining whether the vehicle arriving at the factory is the target truck based on the binding information, and if so, obtaining the actual arrival time of the target truck; if the actual arrival time is within the preset time interval between the planned arrival time, releasing the access control to allow the target truck to enter the factory and enter the unloading area, thereby receiving the target materials.

[0107] The binding information includes the license plate information of the truck with the binding relationship, the material information loaded on the truck, and the planned arrival time of the truck, which is determined based on the first arrival time in the first replenishment document. The target truck is the truck loaded with the target material.

[0108] Specifically, after the supply unit packs the materials according to the first replenishment document, the license plate information of the truck used to transport the materials is bound to the material information, and the binding information is sent to the server through the supply unit's equipment. After the server receives the binding information of the truck and the material sent by the supply unit, it determines whether the vehicle arriving at the factory is a truck transporting the target material through the license plate information of the truck in the binding information. If so, the actual arrival time of the target truck is obtained, and the actual arrival time of the target truck is compared with the planned arrival time in the binding information. If the interval between the actual arrival time and the planned arrival time is within the preset time interval, the access control is lifted to allow the target truck to enter the factory and enter the unloading area, and then the staff unloads the target material to achieve the reception of the target material.

[0109] In this embodiment, by receiving the binding information of the truck and the material sent by the supply unit, it is determined whether the vehicle arriving at the factory is a truck carrying the target material. If so, the actual arrival time of the target truck is obtained, and then a judgment is made based on the actual arrival time of the truck and the planned arrival time. If the interval between the actual arrival time and the planned arrival time is within the preset time interval, the access control is released to allow the target truck to enter the factory and enter the unloading area to receive the target material. In this way, by verifying the actual arrival time of the truck carrying the target material with the planned arrival time determined based on the supply time, the entry authority of the truck carrying the target material can be controlled, thereby improving the efficiency of workshop replenishment.

[0110] In one of the embodiments, when the online trigger timing is reached, an online instruction is sent to the material transportation tool, including: obtaining the third position serial number corresponding to each target assembly station, and obtaining the transportation time period for the material transportation tool to reach the target assembly station from the cache area; determining each online trigger position according to each third position serial number and the transportation time period; when the vehicle assembly progress reaches each online trigger position, sending an online instruction to the material transportation tool.

[0111] Specifically, the server obtains the assembly progress of the vehicle to be assembled in real time, and then the server obtains the third position serial number corresponding to each assembly station that needs to be replenished, and obtains the transportation time period of the material transport tool from the material buffer area to the location that needs to be replenished. The transportation time period of the material transport tool from the material buffer area to each location that needs to be replenished is divided by the production rhythm and rounded up to obtain the number of positions that may be passed from the online trigger position to each location that needs to be replenished. Then, according to each third position serial number and the number of positions that may be passed from the online trigger position to each location that needs to be replenished, the position serial number of the corresponding online trigger position is derived. The server can determine the online trigger position corresponding to each assembly station that needs to be replenished according to the position serial number of the corresponding online trigger position. Then, when the vehicle assembly progress reaches each online trigger position, the server sends an online instruction to the material transport tool.

[0112] In this embodiment, by obtaining the third position serial number corresponding to each target assembly station and the transportation time period of the material transportation tool from the cache area to the target assembly station, and determining each online trigger position according to each third position serial number and the transportation time period, and then when the vehicle assembly progress reaches each online trigger position, an online instruction is sent to the material transportation tool. In this way, the material transportation tool can transport the target material from the material cache area to the production line in a timely manner, realize accurate replenishment of the stations that need replenishment, and improve the efficiency of workshop replenishment.

[0113] In one embodiment, if Figure 3 As shown, the above workshop replenishment method also includes:

[0114] Step 302, obtaining material inventory information, and determining second supply demand information and a second arrival time according to the workshop production plan and the material inventory information.

[0115] The material inventory information is the material information available for production in the factory, including the material information available in the material buffer area in the factory and the material information available in the warehouse outside the factory for storing materials. The second arrival time is the time when the material is transported to the supplier.

[0116] Specifically, the server obtains the information of the materials available for production in the factory, and calculates the second supply demand information that needs to be replenished based on the material demand for production in the production plan minus the information of the materials available for production, which generally includes the type and quantity of the materials that need to be replenished, the equipment distribution method of the materials, and the delivery logistics gate. In addition, after the server obtains the information of the materials available for production in the factory, it can also calculate the time that the remaining materials available for production can maintain production work based on the material demand for production in the production plan minus the information of the materials available for production, and then divide it by the material information that needs to be consumed per day in the production plan, and then determine the second supply time.

[0117] Step 304: Generate a second replenishment document according to the second supply demand information and the second arrival time, and send the second replenishment document to the remote supplier to instruct the remote supplier to transport the materials.

[0118] Among them, long-distance suppliers are suppliers that are far away from the factory. Generally speaking, the time required for long-distance suppliers to transport target materials to the factory by truck is usually measured in days.

[0119] Specifically, after the server determines the second supply demand information and the second arrival time according to the workshop production plan and the material inventory information, it generates a second replenishment document according to the second supply demand information and the second arrival time, and then sends the second replenishment document to the remote supplier to instruct the remote supplier to transport the materials. The second replenishment document records the second supply demand information and the second arrival time, and then the remote supplier can pack, load and transport the target materials to the supply unit according to the equipment allocation method according to the second supply demand information and the second arrival time recorded on the second replenishment document.

[0120] In this embodiment, the server obtains material inventory information through the WMS system (Warehouse Management System), and determines the second supply demand information and the second arrival time according to the workshop production plan and the material inventory information, and then generates a second replenishment document based on the second supply demand information and the second arrival time, and sends the second replenishment document to the remote supplier to instruct the remote supplier to transport the materials. In this way, the remote supplier can transport the materials to the supply unit according to the second supply demand information and the second arrival time recorded on the second replenishment document, ensuring that the supply unit has enough target materials to replenish the factory, thereby improving the efficiency of workshop replenishment.

[0121] The workshop replenishment method of the present application is described in detail below with a specific embodiment:

[0122] It should be noted that in this embodiment, the server is integrated with a MOM system, a DPS system (Digital Processing System), a LES system, and an ETCP system. Among them, the MOM system is used to formulate a production plan and obtain the forward position of the vehicle to be assembled on the production line, and the assembly progress. The production plan includes material requirements, material supply sequence, and material replacement plan that match the production plan. The DPS system is used to specify the assembly location information of the corresponding material under the production model in the production plan. The LES system is used to obtain the production plan in the MOM system and the material inventory information in the WMS system, and controls the order time and the online time according to the vehicle assembly progress. The ETCP system is used to scan the vehicle information arriving at the factory.

[0123] The parameters pre-set in the LES system include: 定序 (position number of the sequencing station), (N 装配 ) The position number corresponding to each assembly station, S max (Cumulative maximum number of parts), T max (maximum cumulative time), t 节拍 (production rhythm), T 配送(the time required to deliver materials from the supplier to the factory access control), T 缓存 (Storage time of materials in the material buffer area in the factory), T 分拣 (Sorting time of small materials such as screws, bolts, nuts, etc. that need to be used together), T 待机 (Waiting time of vehicles arriving at the factory at the access control station), T 运输 (the time required to transport materials from a distant supplier to the supply unit), T 拣货 (The time required for the supplier to pick the goods according to the replenishment document), T 休息补偿 (break time, set in the form of work calendar), T 运送 (Time required to transport materials from the factory material buffer area to the line side).

[0124] Specifically, the staff specifies the production plan through the MOM system, and specifies the assembly location information of the corresponding materials under the production model in the production plan through the DPS system. The production plan includes material requirements, material supply sequence, and material replacement plan that match the production plan. After receiving the production plan and vehicle assembly progress sent by the MOM system, the LES system generates the first replenishment document. The first replenishment document records the first supply demand information (including material type, material quantity), the consumption sequence of each material, the material equipment allocation method, the equipment sequence, the delivery logistics gate, the receiving storage area, the estimated consumption time of the parts, the first arrival time, the reference delivery time, the reference picking time, and the packable mark. Among them, the equipment allocation method of the material is determined by the LES system based on the production task information of the online workstation, so that different materials at the same workstation are divided into the same production plan quantity for ordering. The materials of the same workstation from different sources in the factory are integrated into one tool in boxes, and all materials in this tool are put online and returned at the same time.

[0125] It should be noted that after the LES system receives the production plan and vehicle assembly progress from the MOM system, it determines the position number N of the first target assembly station according to the vehicle assembly progress. 装配 , and then determine the position number N of the order triggering station according to formula (3) 发单触发 :

[0126] N 发单触发 =N 装配 -(T 拣货 +T 配送 +T 待机 +T 缓存 +S max *t 节拍 ) / t 节拍 (3)

[0127] Among them, (T 拣货 +T 配送+T 待机 +T 缓存 +S max *t 节拍 ) is the time required for the vehicle to be assembled to move from the order departure position to the first target assembly station.

[0128] When the target material is a small material such as screws, bolts, nuts, etc. that needs to be used in combination, the position number N of the order triggering station is determined according to formula (4): 发单触发 :

[0129] N 发单触发 =N 装配 -(T 拣货 +T 配送 +T 待机 +T 分拣 +T 缓存 +S max *t 节拍 ) / t 节拍 (4)

[0130] When the MOM system obtains that the assembly progress of the vehicle to be assembled has reached the order triggering station, the LES system calculates the material information of the target materials required for each target assembly station in turn according to the workshop production plan and the assembly station information of the corresponding materials under the production model in the production plan, until the material quantity obtained by the sequential calculation reaches the cumulative maximum number of parts or the cumulative time reaches the maximum cumulative time, and stops to obtain the first supply demand information.

[0131] In addition, after the LES system receives the production plan and vehicle assembly progress from the MOM system, the LES system obtains the position number N of the sequencing station. 定序 , at the sequencing station, count the time T that the vehicle to be assembled passes through the sequencing station 0 and the order of passing (another mode is to calculate the time T passing through the sequencing station based on the planned order in the workshop production plan and the time when the vehicle to be assembled is put on the line in the workshop production plan 0 ), and then determine the order of consumption of each material (also the order in which the materials are placed in the equipment). In this way, the LES system obtains the position number N corresponding to the first target assembly station in the production line 装配 According to formula (1), the first time period T required for the vehicle assembly progress to reach the first target assembly station can be determined 1 , and determine the first arrival time T according to formula (2) 到货 :

[0132] T 1 =T 0 +(N 定序 -N 装配 )*t 节拍 +T休息补偿 (1)

[0133] T 到货 =T 1 -(T 配送 +T 缓存 )-T 休息补偿 (2)

[0134] When the target material is a small material such as screws, bolts, nuts, etc. that needs to be used together, T is determined according to formula (5). 到货 :

[0135] T 到货 =T 1 -(T 配送 +T 缓存 +T 分拣 )-T 休息补偿 (5)

[0136] In one embodiment, the LES system can also determine the reference delivery time T according to equations (6) and (7): 发货 and reference picking time T 拣配 For reference of suppliers:

[0137] T 发货 =T 到货 -(T 拣货 +T 配送 ) (6)

[0138] T 拣配 =T 发货 -T 拣货 (7)

[0139] After the LES system determines the first supply demand information and the first arrival time, it generates the first replenishment document and sends the first replenishment document to the supplier. The supplier supplies the goods according to the first supply demand information and the first arrival time recorded on the first replenishment document, packs and loads the target materials according to the equipment allocation method, and binds the license plate information of the truck loaded with the target materials with the material information through the equipment of the supplier to generate binding information. After the binding is successful, the binding information is sent to the LES system, and the LES system synchronizes the binding information to the ETCP system. It should be noted that the binding information includes the planned arrival time determined based on the first arrival time in the first replenishment document. After the truck loaded with the target materials arrives at the factory, the ETCP system scans the vehicle information and compares the planned arrival time of the truck with the actual arrival time. If the time matches, the access control is released, otherwise it remains closed.

[0140] After the truck loaded with the target material enters the factory, it enters the waiting area to wait. At the same time, the LES system obtains the material information on the truck in the waiting area and determines whether there are urgent materials. If there are, the truck loaded with urgent materials is instructed to skip the waiting area and go directly to the unloading area to unload. In the unloading area, the truck is unloaded by logistics personnel and the materials are delivered to the material buffer area in the factory according to the production plan.

[0141] It should be noted that the MOM system obtains the assembly progress of the vehicles to be assembled on the production line in real time. When the MOM system obtains each assembly station that needs to be replenished, it synchronizes the vehicle assembly progress to the LES system. The LES system obtains the corresponding position number N for each assembly station that needs to be replenished. 装配 , and obtain the transportation time T of the material transportation tool to transport the material from the material buffer area to the location where replenishment is required 运送 , and then according to formula (8) we can get the position number N of the online trigger position 上线触发 :

[0142] N 上线触发 =N 装配 -T 运送 / t 节拍 (8)

[0143] Among them, T 运送 / t 节拍 Round upwards.

[0144] When the MOM system obtains that the vehicle assembly progress has reached the online trigger position, the MOM system synchronizes the vehicle assembly progress to the LES system. The LES system sends an online instruction to the material transport tool. The material transport tool transports the target material in the cache area to the production line according to the online instruction.

[0145] The production line uses the target materials transported by material transport tools to carry out production activities. When the target materials are consumed, the LES system issues a return command to transport the empty equipment from the production line back to the unloading area. Then the staff loads the empty equipment onto the supplier's delivery vehicle according to the production plan, and the supplier takes it away. After the supplier takes back the empty equipment, it waits for the next replenishment instruction and starts replenishing the factory according to the replenishment document.

[0146] In one of the embodiments, when the target material is a smaller material such as screws, bolts, nuts, etc. that needs to be used in conjunction with each other, when the supplier packs and loads the target material, the smaller materials such as screws, bolts, nuts, etc. that need to be used in conjunction with each other need to be packed with their corresponding minimum packaging units first. Materials of the same workstation, date, and vehicle sequence are divided into the same material batch, and this batch forms a serial code (batch code), which is then combined with the packaging distribution method of the material to form a generated document. When generating a document, a serial code is generated with the same arrival time period attribute (or materials used in the same batch and vehicle sequence), the same receiving storage area, and the same equipment code. When binding the package during the picking operation, the documents bound to the same package are verified, and those with the same serial code can be bound together, otherwise the verification fails to ensure the accuracy of the packaging operation (grouping operation).

[0147] In addition, when a replenishment document is generated, the code representing the packaging type will be recorded on the document. During picking operations, the unique serial code representing the packaging on the packaging needs to be bound to the document, and the fields in the packaging serial code are matched and verified with the packaging type code on the document. If it passes, binding is allowed, otherwise it fails, to ensure that the correct packaging is used during picking.

[0148] It should be noted that multiple smaller materials that need to be used together can be replenished by multiple supply units. Multiple supply units pick materials according to replenishment documents to form several packaging units. After multiple supply units deliver multiple smaller materials to the factory, the staff in the factory will use AGV goods-to-person delivery technology to sort the packaging units to the same online equipment for the second time according to the same batch code. This achieves the purpose of consuming multiple materials from multiple sources on the production line side at the same time and returning the equipment at the same time, saving the area occupied on the line side.

[0149] In one embodiment, the document is generated according to the minimum packaging unit of the material, and a unique serial code is formed. The serial codes of the packaging units of the same type of materials are distinguished in order, and the serial codes are arranged in ascending order to form a verification queue to obtain the verification order of the arrival of the materials. For the mechanized unloading place, the LES system will send the verification order of the arrival of the materials to the mechanized central control, and the mechanized equipment will collect the material information and perform verification to prevent the wrong order of the materials.

[0150] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.
