In addition, for clarity and brevity, the description of known functions and structures is omitted.

[0051] It should be understood that the references to "one embodiment" or "an embodiment" throughout the specification mean that the specific features, structures, or characteristics associated with the embodiment are included in at least one embodiment of the present invention. Therefore, the references to "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. In addition, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0052] In various embodiments of the present invention, it should be understood that the sequence numbers of the following processes do not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0053] Embodiment 1

[0054] The embodiment of the present invention provides a material distribution management system based on the WMS system (hereinafter referred to as the system), such as Figure 1 As shown, the system includes: a basic data module 10, a work order analysis module 20, a batching and mixing module 30, and a warehouse delivery verification module 40. Specifically:

[0055] The basic data module 10 is used to store material information, which at least includes material name, material quantity, material location and material attributes.

[0056] The material name refers to the lot, that is, the batch number, and the material attributes are supplementary descriptions of the batch lot.

[0057] Exemplarily, the material information may include the information shown in Table 1 below.

[0058] Table 1

[0059]

[0060] The lot number is the material name, the material quantity is the quantity corresponding to the batch lot, the material location is the storage location corresponding to the batch lot, and the Owner, Product, and Device are the material attributes of the batch lot.

[0061] In actual applications, the system background provides a basic data maintenance section, which mainly includes AO material number (referring to the output material number of Assy), Device chip material number, chip bundle quantity, Assy material size quantity, Lot Size range, IE Size, ratio, main and auxiliary Die, etc.

[0062] The method of obtaining material information in the embodiment of the present invention can be to obtain material information by reading the RFID (Radio Frequency Identification) information of the material, and then enter the obtained material information into the system. In the practical application of the present invention, by binding RFID tags to goods one by one, using a PDA card reader to read the material information on the goods and store it in the system, each batch of materials can have a unique RFID code information record and be stored in the system.

[0063] The work order parsing module 20 is used to generate a WMS work order template according to the customer work order and the SAP work order.

[0064] In actual applications, the work order parsing module 20 generates a WMS work order template by parsing the contents of the customer work order and the SAP work order, combined with the SAP Picking list (SAP material delivery details), for guiding the material delivery operation.

[0065] For example, in combination Figure 2As shown in the figure, the SAP Picking list includes at least: Order (work order number), Group (group), Materials (materials), Materials Description (material description), Plant (plant code), Location (site), SAP Batch No (SAP batch number), MES Lot Number (MES lot batch number), Fablot Number (Fab plant batch number), BU Owner (product owner), Order Remain Qty (work order remaining quantity), Stock Qty (stock quantity of lot batch number), etc.

[0066] The batching and combining module 30 is used to generate batching and combining operation instructions according to the WMS work order template, batch inventory information that meets the work order material issuance requirements, and batching and combining rules, and complete the automatic batching and combining of original batch materials.

[0067] In actual applications, SAP Picking List is the batch inventory information generated by the SAP system that meets the work order delivery requirements, mainly including work order number, batch lot, work order quantity, etc. The system background is configured with batch separation and combination rules for different products and materials. The system generates batch separation and combination operation instructions based on the material information and the batch separation and combination rules maintained in the background, and completes the material batch separation and combination operations.

[0068] Illustratively, the batch splitting and merging rules in the embodiment of the present invention are shown in Table 2 below.

[0069] Table 2

[0070]

[0071]

[0072] Considering that the inventory quantity of each batch lot is different, in order to meet the IE Size, it is necessary to split the original batch lot into large batches and merge the small batches. Specifically, when the inventory quantity of a single batch lot is greater than IESize, it is split first; when the inventory quantity of a single batch lot is less than IE Size, it is merged first.

[0073] Before sending the materials in the warehouse to the production line, the batching module 30 of the present invention will automatically batch and combine the original inventory batch materials (such as splitting the batch lots of large quantity inventory and combining the batch lots of small quantity inventory) to meet the IE Size material delivery requirements.

[0074] The outbound verification module 40 is used to generate a material outbound list according to the batch separation and combination operation instruction book, and verify the outbound materials recorded in the material outbound list, wherein the outbound materials that pass the verification are allowed to be shipped out.

[0075] In actual applications, by binding RFID tags to goods one by one, using PDA card readers to read the material information on the goods and store it in the system, each batch of materials can have a unique RFID coding information record and be stored in the system. In this way, when leaving the warehouse, the RFID tags of the goods to be shipped can be read by the PDA reader, and the material information read can be verified with the material information on the material shipment list. If the verification is correct, the material is allowed to leave the warehouse.

[0076] As a preferred embodiment of the present invention, the material distribution management system based on the WMS system provided by the present invention also includes a work order tracking template 50, such as Figure 3 shown.

[0077] The work order tracking template 50 is used to track the execution status of the SAP work order based on the material preparation data, the data of the goods shipped out of the warehouse, and the corresponding total demand data of the work order.

[0078] The data on shipped goods refers to the quantity that has completed batch separation and combination operations and has been shipped to the production line, and the data on material preparation refers to the quantity that has been taken off the shelves and completed batch separation and combination operations but has not yet been shipped out.

[0079] The embodiment of the present invention records the number of products that have completed batching and batching operations and have been shipped to the production line in the system as shipped data, and records the data that have been removed from the shelves and completed batching and batching operations but have not been shipped as material preparation data in the system's material preparation database. The system compares the material preparation data and shipped data with the total work order demand data recorded in the SAP work order to determine the execution status of the work order.

[0080] Specifically, according to the total demand quantity of the work order - the data that has been shipped out - the quantity of prepared materials = the remaining quantity of the work order, the material batching operation is continuously performed for the unfinished work order until the work order material delivery is completed.

[0081] If the required quantity of the work order has been completed, the system will automatically deduct and no longer perform the batching operation on this work order. If the required quantity of the work order has not been completed, the system will execute the corresponding quantity to be issued based on the remaining unfinished data, and perform the batching operation on the inventory again to ensure that each work order requirement is 100% completed. The present invention can track the execution and completion of the work order to ensure that the production of each work order is 100% executed.

[0082] Embodiment 2

[0083] The embodiment of the present invention provides a material distribution management method based on a WMS system, which is applied to the material distribution management system based on the WMS system (hereinafter referred to as the system) as described above. Figure 4 As shown, the method includes:

[0084] Step 101, generating a WMS work order template according to the customer work order and the SAP work order.

[0085] In the embodiment of the present invention, the system generates a WMS work order template (also referred to as a WMS work order delivery template) by parsing the content of the customer work order and the content of the SAP work order.

[0086] The SAP work order includes Plant (SAP work order number, which refers to the factory code in SAP), Factory, Order Number, Order Type, Material, MES Material (batch lot material number in SAP), 2A Input PN (SAP target input material), priority, over-issuance, Status, Tasklist description, Total Order Quantity (total work order requirement quantity), material preparation quantity on duty, External Device, etc.

[0087] The WMS work order template generated by the present invention based on the customer work order and the SAP work order is as follows: Figure 5 As shown, it may include OrderNumber, Order Type, Material, MES Material, 2A Input PN, Priority, Over-issuance, Total OrderQuantity, Material Quantity on Shift, External Device and other information.

[0088] In actual applications, the system will first parse the content of the customer's work order to identify the special requirements in the customer's work order, and generate it into SAP work order information that the system can recognize. The system will then uniformly export the WMS work order template from the SAP system. For example, the special requirements in the customer's work order include priority, over-issuance, clearing the DIE quantity, the minimum quantity limit for material delivery, work order-specified batches, and work order-specified material numbers. Before generating the WMS work order template, the system first converts the special requirements of the customer's work order into the SAP work order, such as the priority description in the SAP work order, which product should be prioritized for production, whether over-issuance is allowed, whether DIE or inventory needs to be cleared, whether there is a minimum quantity limit for material delivery, whether there is a specified batch number for material delivery, whether there is a specified material number, etc. These are all combined with the requirements of the customer's work order by the system and then implemented in the content of the SAP work order, and finally the WMS work order template is exported from the SAP system.

[0089] Step 102, based on the WMS work order template, the batch inventory information that meets the work order material delivery requirements, and the batch separation and combination rules, generate a batch separation and combination operation instruction, and complete the automatic batch separation and combination of the original batch materials.

[0090] The batch inventory information that meets the work order delivery requirements can be the SAP Picking list generated by the SAP system. The SAP picking list mainly includes work order number, batch lot, work order quantity, etc. Considering that the inventory quantity of each batch lot is different, in order to meet the IE Size, it is necessary to split the original batch inventory for large quantities and merge the original batch inventory for small quantities.

[0091] Specifically, when the inventory quantity of a single batch lot is greater than the IE Size, it is split first; when the inventory quantity of a single batch lot is less than the IE Size, it is merged first.

[0092] For example, assuming that the original inventory quantity of a batch lot is 828 pieces, if the IE Size requires 800 pieces, then the present invention will split the 828 pieces into 800+28, and then these 28 pieces will be batched with other batch lots according to the batching rules. Batching is to meet the quantity required by IE Size. In actual applications, the inventory quantity of each batch lot will not be constant, and the quantity may be large or small. When the inventory quantity of a batch lot is greater than the IE Size (referring to the lot Size that best meets the production capacity in terms of maximizing production capacity), it needs to be split. Similarly, when the inventory quantity of a batch lot is less than the IE Size, it will be batched to maximize production capacity and reduce waste.

[0093] The splitting and merging rules are defined based on customer name, product category, and material attributes. An example is as follows:

[0094] ①First determine whether the customer names of the products are the same. Only products of the same customer can be batched together;

[0095] ② Secondly, determine whether the material properties are consistent. Only products with the same material properties are allowed to be batched together.

[0096] Combined with the batch combination demand judgment rules shown in Table 2 above, the first three batches can be combined because the customer names and material attributes are consistent. The first four batches cannot be combined because although the customer names are the same, the product categories and material attributes are different. At the same time, it is obvious that the five batches cannot be combined because the customer names of the five batches are inconsistent.

[0097] ③Finally, the batches should be divided and combined based on the lot size requirements of each product and the proportion requirements of the mix.

[0098] As shown in Table 3 below, when the batching attributes meet the requirements, they are further subdivided into specific batching and splitting logic.

[0099] Table 3

[0100]

[0101]

[0102]

[0103]

[0104]

[0105]

[0106] It should be noted that different types of products will have different packaging quantities. For different packaging quantities, when there is a need to distribute materials with a certain ratio, it is necessary to consider how to operate to achieve the optimal solution. See Table 4 below.

[0107] Table 4

[0108] Product Type Number of disks Whole pack quantity LordDie 4 40 pcs Die 1 6 60 pcs Die 2 9 90 pcs

[0109] Assume that when the main die is running and 200 products need to be produced, 5 whole packages of "4 dies / single tray" can be directly taken to fully meet the production needs.

[0110] Assuming that three different types of products, namely, main Die, sub Die 1 and sub Die 2, are used to make the proportion of main and sub Dies, it will be found that because "60 pieces / pack" and "90 pieces / pack" are not multiples of 200, according to the previous manual batching operation method, it will take a lot of manpower and time to perform a large number of picking and batching operations on the inventory quantities of "60 pieces / pack" and "90 pieces / pack". However, by adopting the material distribution management system based on the WMS system provided by the embodiment of the present invention, the core algorithm in the system can quickly process the materials that can be dispatched in the inventory (i.e., the Picking list of SAP) in a centralized manner, thereby obtaining a reasonable batching and batching operation instruction.

[0111] In the embodiment of the present invention, when the batching attribute requirements are met, the optimal batching and combining operation logic will be calculated in combination with the Lot Size requirements of each product and the proportion requirements of the ratio, and then a batching and combining operation instruction book corresponding to the optimal batching and combining operation logic will be generated, and the automatic batching and combining of the original batch materials will be completed according to the optimal batching and combining operation logic.

[0112] Combination Figure 6 As shown, the optimal batch operation logic for calculating the optimal batch operation in the embodiment of the present invention includes:

[0113] Step 201, according to the batch inventory information that meets the work order material delivery requirements and the target lot size requirements, find out whether there is a first target lot that meets the target lot size requirements; if so, execute step 202, if not, execute step 203;

[0114] The batch inventory information that meets the work order delivery requirements is the SAP Picking list generated by the SAP system, which mainly includes work order number, batch lot, work order quantity, etc. The target lot size requirement is, for example, the IE size requirement.

[0115] Step 202, determining that the first target lot is the optimal solution, and calculating the optimal batch splitting and merging operation logic according to the first target lot;

[0116] If there is a first target lot that completely matches the target lot size requirement, the first target lot is preferentially used as the optimal solution, and the optimal batch splitting and merging operation logic is calculated based on the first target lot. In the embodiment of the present invention, the target lot that completely matches the target lot size requirement is preferentially used.

[0117] Step 203, searching whether there is a second target lot that is larger than the target lot size requirement; if so, executing step 204; if not, executing step 205;

[0118] Step 204, calculating and obtaining the optimal batch splitting and merging operation logic according to the second target lot;

[0119] In actual applications, try not to unpack the packages. Use the bundle as the unit. If unpacking is necessary, first unpack the lot with the largest quantity, and try to use the lot with the earliest time to avoid excessive squeezing of the lot with the earliest time.

[0120] Step 205, searching whether there is a third target lot smaller than the target lot size requirement; if so, executing step 206; if not, returning to executing step 201;

[0121] Step 206, calculate and obtain the optimal batch splitting and merging operation logic according to the third target lot.

[0122] Combined with batch operation instructions Figure 7 , Figure 8 As shown. Taking IE Size of 360 as the standard, Figure 7 The original inventory quantity of the batch lot shown is 480 pieces. At this time, it needs to be split into 360+120 pieces. Figure 8 The number of lots in the three batches shown is less than the IE Size, so they are batched together under the premise of meeting the batching rules.

[0123] Before sending materials from the warehouse to the production line, the system of the present invention will automatically divide and merge the original inventory batch materials (such as splitting batches of large quantity inventory and merging batches of small quantity inventory) to meet the IE Size material delivery requirements.

[0124] The present invention completely completes batch division and batch combination automatically according to the batch division and combination rules and generates batch division and combination operation instructions, completely replacing the error risks caused by manual judgment and operation in the past.

[0125] Step 103, generating a material outbound list according to the batch separation and combination operation instruction book, and verifying the outbound materials recorded in the material outbound list, wherein the outbound materials that pass the verification are allowed to be shipped out.

[0126] The embodiment of the present invention verifies all outbound materials recorded on the outbound material list. In actual operation, by binding RFID tags to goods one by one, using PDA card readers to read the material information on the goods and linking with the system, each batch of materials can have a unique RFID coding information and be recorded and stored in the material distribution management system based on the WMS system.

[0127] When materials are shipped out of the warehouse, the present invention will check and verify the physical information of the lot (i.e., the information of the shipped materials, such as the lot batch number and quantity) with the information recorded and stored in the system (such as the lot batch number and quantity). Because the lot batch number is bound to the RFID one-to-one, when reading the RFID information, the system will automatically identify which batch lot this RFID is bound to, and then perform a one-to-one verification with the physical lot. RFIDs with inconsistent verification information are not allowed to be unbound and shipped out of the warehouse. Only when the lot or work order (work order number) or Qty information is consistent will the RFID verification be passed and the shipment be allowed, thereby ensuring the correctness of the delivery of materials.

[0128] The present invention replaces the disadvantages of previous manual visual verification, and automatically verifies the physical object RFID information with the system information by scanning the code, thereby ensuring 100% correctness of the physical object leaving the warehouse.

[0129] More preferably, if Fig. 9 As shown, the material distribution management method based on the WMS system provided by the embodiment of the present invention may also include:

[0130] Step 104 , tracking the execution status of the SAP work order based on the material preparation data, the data of the goods shipped out of the warehouse, and the corresponding total demand data of the work order.

[0131] In the embodiment of the present invention, the shipped data refers to the quantity that has completed the batching operation and shipped to the production line, and the material preparation data refers to the quantity that has been taken off the shelf and completed the batching operation but the physical objects have not been shipped. In the embodiment of the present invention, the quantity that has completed the batching operation and shipped to the production line is recorded in the system as the shipped data, and the quantity that has been taken off the shelf and completed the batching operation but the physical objects have not been shipped is recorded in the system's material preparation database as the material preparation data. The system compares the material preparation data, the shipped data, and the total work order demand data recorded in the SAP work order to determine the execution status of the work order.

[0132] Specifically, according to the total demand quantity of the work order - the data that has been shipped out - the quantity of prepared materials = the remaining quantity of the work order, the material batching operation is continuously performed for the unfinished work order until the work order material delivery is completed.

[0133] If the required quantity of the work order has been completed, the system will automatically deduct and no longer perform the batching operation on this work order. If the required quantity of the work order has not been completed, the system will execute the corresponding quantity to be issued based on the remaining unfinished data, and perform the batching operation on the inventory again to ensure that each work order requirement is 100% completed. The present invention can track the execution and completion of the work order to ensure that the production of each work order is 100% executed.
