[0027] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0028] The present disclosure provides a material demand inventory allocation method and device to optimize the material demand inventory allocation process. Figure 1 is a flow chart of a material requirement inventory allocation method according to an exemplary embodiment. It should be noted that the material requirement inventory allocation method of the embodiment of the present disclosure can be used in the material requirement inventory allocation device in the embodiment of the present disclosure, and the material requirement inventory allocation device in the embodiment of the present disclosure can be configured in an electronic device. Figure 1 As shown, the material requirement inventory allocation method may include but is not limited to the following steps.

[0029] Step 101, obtain the production demand information of production projects under multiple factories, the material inventory information of multiple warehouses and the BOM information, wherein the material inventory information of the warehouse includes the material identification information, inventory quantity and factory information of the factory to which the material can be supplied, and the BOM information includes the available material information of multiple different production projects.

[0030] It should be noted that each factory can meet the production needs of multiple production projects. The warehouse stores the materials required for factory production. During the factory production process, the material inventory in the corresponding warehouse will be allocated to the production projects under each factory according to the production needs of the production projects.

[0031] As an example, the production demand information of a factory can refer to Table 1, which includes the demand quantities corresponding to different production projects under multiple factories. As can be seen from Table 1, the demand quantity of the M1 project under factory LOC1 is D1, and the demand quantity of the M2 project is D2. The demand quantity of the M3 project under factory LOC2 is D3.

[0032] Table 1

[0033] project factory Required quantity M1 LOC1 D1 M2 LOC1 D2 M3 LOC2 D3

[0034] The material inventory information of the warehouse can be referred to Table 2. Table 2 shows the materials stored in multiple warehouses, the inventory, and the material supply relationship between the warehouse and the factory. Warehouse W1 stores material MPN01 with an inventory of INV1, and warehouse W1 can supply materials for the production of factory LOC1. Warehouse W2 stores material MPN02 with an inventory of INV2, and can supply materials for the production of factory LOC2. Warehouse 3 has materials MPN01 and MPN02, with inventory of INV3 and INV4 respectively, which can supply the production needs of both factory LOC1 and factory LOC2.

[0037] The BOM information can be found in Table 3. In Table 3, the BOM information includes the available material information of different production projects under multiple factories (where Y represents available and N represents currently unavailable). As can be seen from Table 3, the available materials for the M1 project are material MPN01 and material MPN02. The available material for the M2 project is material MPN02. The available material for the M3 project is material MPN01.

[0040] Step 102: Determine production constraint information based on BOM information.

[0041] It should be noted that, since different production projects have different usable materials, each production project cannot arbitrarily use the inventory of each material in each factory. Therefore, the production constraint relationship information can be determined based on the BOM information. The production constraint relationship is used to describe that if production project j cannot use material i, then production project j cannot use the inventory of material i in any factory l. As an example, the production constraint relationship information can be expressed by the following formula, which is used to describe that if production project j cannot use material i, then the inventory of material i in any factory l where material i can be allocated to production project j is 0:

[0042] x i,j,l =0,l=1,2,…,L

[0043] Where L is the total number of factories.

[0044] Step 103, determining the warehouse location restriction information and the maximum supply restriction information of the inventory according to the production demand information of the production items of the multiple factories and the material inventory information of the multiple warehouses.

[0045] It should be noted that due to limiting factors such as distance, the warehouse corresponding to each factory cannot supply materials to each production project at will, and the total amount of materials supplied by each warehouse for multiple production projects cannot exceed the inventory of the material in the warehouse. Therefore, the warehouse location restriction information and the maximum supply restriction information of the inventory can be determined based on the production demand information of the production projects under multiple factories and the material inventory information of multiple warehouses. The warehouse location restriction information of the inventory is used to describe the supply relationship between the production project and the warehouse corresponding to the factory. If production project j cannot use the warehouse inventory corresponding to factory l, then production project j cannot use all the materials in the warehouse under factory l. The maximum supply restriction information is used to describe that under factory l, the total usage of each material i by all production projects j that can use the inventory of factory l is not greater than the inventory of material i under factory l.

[0046] As an example, the warehouse location restriction information of the inventory can be expressed by the following formula, which is used to describe that due to restrictions such as distance, production project j cannot use all materials i under factory l. In this case, the inventory of all materials i in factory l that can be allocated to production project j is 0:

[0047] x i,j,l =0,i=1,2,…,I

[0048] Among them, I is the total number of all material types under factory l.

[0049] The maximum supply limit information can be expressed by the following formula, which is used to describe that the total usage of each material i by all production items j that can use the inventory of factory l under factory l is not greater than the inventory of material i under factory l:

[0050]

[0051] Among them, Inv i,l is the inventory quantity of material i in factory l.

[0052] Step 104, obtaining the priority of each production item, the priority of each factory among multiple factories, and the priority of each material among all materials in multiple warehouses.

[0053] The priority of each production project, factory, and material can be set according to the actual production scenario. As an example, taking Table 2 as an example, there are two materials stored in warehouse W1, warehouse W2, and warehouse W3, material MPN01 and material MPN02. Among them, material MPN01 in warehouse W1 and material MPN01 in warehouse W3 have the same priority.

[0054] Step 105, based on the priority of each production item, the priority of each factory, the priority of each material, the production constraint relationship information, the warehouse location restriction information of the inventory and the maximum supply restriction information, determine the material demand inventory allocation information.

[0055] In a possible implementation, the allocation of material demand inventory can be determined based on production constraint information, inventory warehouse location restriction information, and maximum supply restriction information, while satisfying multiple constraints in actual production scenarios, by comprehensively considering the priorities of different production projects, factories, and materials. For example, based on the constraints, production projects with high priorities are preferentially satisfied.

[0056] It should be noted that the material demand inventory allocation information is the inventory of material i in factory l to which production project j can be allocated. Optionally, in some embodiments of the present disclosure, the purchase list information can also be determined based on the material demand inventory allocation information and the material inventory information of multiple warehouses to replenish the material inventory in a timely manner.

[0057] By implementing the embodiments of the present disclosure, the production constraint relationship information, inventory warehouse location restriction information and maximum supply restriction information in the actual production scenario are comprehensively considered, the material demand inventory allocation information is determined on the basis of meeting the priorities of different production projects, factories and materials, and the material inventory is accurately allocated. This is suitable for production scenarios with multiple warehouses and multiple factories, and improves the material demand satisfaction rate and material management efficiency.

[0058] It should be noted that there may be an alternative relationship between materials used to produce the same finished product (or it can be understood as having multiple suppliers), and the YN available certification status under the BOM of different projects is different, which means that different projects can use different combinations of material suppliers.

[0059] In the related art, materials can be allocated according to certain deduction rules or logics, such as directly using the priority of material use to allocate material inventory according to the priority of production projects. However, this method cannot take global information into consideration well. For example, for the first production project, both material A and material B can be used (for the first production project, material A and material B have a replacement relationship), while the second production project can only use material B. If the available materials for subsequent demand are not considered during processing, and the inventory of material B is directly allocated when the first production project is met, the second production project will not be met, and material A will also become stagnant. In order to reduce such problems to a certain extent, the present disclosure proposes another material demand inventory allocation method. Figure 2 FIG. 1 is a flow chart of another material requirement inventory allocation method according to an exemplary embodiment. Figure 2 As shown, the material requirement inventory allocation method may include but is not limited to the following steps.

[0060] Step 201, obtain the production demand information of production projects under multiple factories, the material inventory information of multiple warehouses and the BOM information, wherein the material inventory information of the warehouse includes the material identification information, inventory quantity and factory information of the factory to which the material can be supplied, and the BOM information includes the available material information of multiple different production projects.

[0061] Step 202: Determine production constraint relationship information based on BOM information.

[0062] Step 203, according to the production demand information of the production items of the multiple factories and the material inventory information of the multiple warehouses, determine the warehouse location restriction information and the maximum supply restriction information of the inventory.

[0063] Step 204, obtaining the priority of each production item, the priority of each factory among multiple factories, and the priority of each material among all materials in multiple warehouses.

[0064] Step 205, based on the production demand information of the production items under the multiple factories, determine the demand quantity of each production item.

[0065] Step 206, based on the priority of each production project, the demand of each production project and the inventory of materials to be allocated for each production project, determine the total shortage of materials for multiple different production projects, wherein the inventory of materials to be allocated refers to the inventory of each material that can be allocated to each factory.

[0066] It should be noted that the material shortage of a production project can be used as one of the business logic requirements that need to be considered in an actual production scenario. In the material allocation business, it is hoped that the production needs of more production projects can be met as much as possible to reduce the total material shortage. Among them, the difference between the demand of each production project and the inventory of materials to be allocated is the actual material shortage of each production project. In the embodiment of the present disclosure, the proportion of the material shortage of high-priority production projects in the total material shortage can be increased, so that when the production needs of production projects are met, materials can be allocated to high-priority production projects first.

[0067] Step 207, based on the priority of each production project, the priority of each factory, the priority of each material and the inventory of materials to be allocated for each production project, determine the total amount of material demand inventory allocation business.

[0068] Among them, the total amount of material demand inventory allocation business is the total amount of materials that can be provided for production projects under multiple factories in all warehouse inventories. It should be noted that the substitution relationship between materials can also be considered in the business logic requirements, hoping to make full use of the existing warehouse material inventory to supply materials for more production projects, to maximize the total amount of material demand inventory allocation business, and reduce material stagnation.

[0069] In one implementation, the sum of the priority of the jth production project, the priority of the lth factory, and the priority of the ith material can be used as the weight of the inventory of materials to be allocated for the jth production project (the inventory of the ith material in the lth factory to which the jth production project can be allocated), thereby determining the total amount of material demand inventory allocation business for all production projects. In the disclosed embodiment, when determining the total amount of material demand inventory allocation business, the priorities of each production project, factory, and material in multiple dimensions are comprehensively considered to meet the priority requirements of different dimensions.

[0070] Step 208, based on the total shortage of materials and the total amount of material demand inventory allocation business, combined with production constraint relationship information, inventory warehouse location restriction information and maximum supply restriction information, determine material demand inventory allocation information.

[0071] It should be noted that the production constraint relationship information, inventory warehouse location restriction information and maximum supply quantity restriction information are restrictions on the inventory quantity of materials to be allocated for each production project. In a possible implementation, the inventory quantity of materials to be allocated for each production project can be adjusted in combination with the production constraint relationship information, inventory warehouse location restriction information and maximum supply quantity restriction information. Taking into account the priorities and restrictions of different production projects, factories and materials, the total shortage of materials can be reduced as much as possible, and the total amount of material demand inventory allocation business can be increased to meet the business logic requirements.

[0072] In the embodiment of the present disclosure, step 201 to step 204 may be implemented in any manner in the embodiments of the present disclosure, and the embodiment of the present disclosure does not limit this and will not be described in detail.

[0073] By implementing the disclosed embodiments, the constraints of production constraint relationship information, inventory warehouse location restriction information, maximum supply restriction information, and priorities of different production projects, factories, and materials are comprehensively considered, and the total amount of material shortage and the total amount of material demand inventory allocation business are used as the business logic requirements to be met to determine the material demand inventory allocation information. It can be applied to production scenarios with multiple warehouses and multiple factories, and material inventory allocation can be performed more accurately, and it can also reduce the stagnation of materials, further improve the material demand satisfaction rate and material management efficiency, and optimize the material demand inventory allocation process.

[0074] Figure 3 FIG. 1 is a flow chart of another material requirement inventory allocation method according to an exemplary embodiment. Figure 3 As shown, the material requirement inventory allocation method may include but is not limited to the following steps.

[0075] Step 301, obtain the production demand information of production projects under multiple factories, the material inventory information of multiple warehouses and the BOM information, wherein the material inventory information of the warehouse includes the material identification information, inventory quantity and factory information of the factory to which the material can be supplied, and the BOM information includes the available material information of multiple different production projects.

[0076] Step 302: Determine production constraint relationship information based on BOM information.

[0077] Step 303, determining the warehouse location restriction information and the maximum supply restriction information of the inventory according to the production demand information of the production items of the multiple factories and the material inventory information of the multiple warehouses.

[0078] Step 304, obtaining the priority of each production item, the priority of each factory among multiple factories, and the priority of each material among all materials in multiple warehouses.

[0079] Step 305, based on the production demand information of the production items under the multiple factories, determine the demand quantity of each production item.

[0080] Step 306: Calculate the difference between the demand of each production item and the inventory of materials to be allocated for each production item to obtain the shortage of materials for each production item.

[0081] Step 307 , performing weighted sum processing based on the priority of each production project and the material shortage amount of each production project, to obtain the total material shortage amount of multiple different production projects.

[0082] As an example, the total shortage of materials for different production items can be expressed as follows:

[0083]

[0084] Among them, M is the total amount of material shortage for different production projects, d j is the demand for production item j, ∑ i,l x i,j,l is the inventory of materials to be allocated for production project j (the inventory of the i-th material in the l-th factory to which the j-th production project can be allocated), d j -∑ i,l x i,j,l is the material shortage of production item j, W j is the priority of production item j. The higher the priority of production item j, the higher the W j The larger it is, the greater the weight value assigned.

[0085] Step 308, based on the priority of each production project, the priority of each factory, the priority of each material and the inventory of materials to be allocated for each production project, the total amount of material demand inventory allocation business is determined using the first formula.

[0086] Among them, the first formula is expressed as follows:

[0087]

[0088] Where N is the total amount of material demand inventory allocation business, W j is the priority of the jth production item, U l is the priority of the lth factory, V i is the priority of the ith material, x i,j,l is the inventory of materials to be allocated for the jth production item.

[0089] In the first formula, the higher the priority of factory l, the higher the U l The larger the value, the higher the material usage priority. i The larger the value, the higher the priority of factory l, material i, and production item j. j *(U l *100+V i ) This combination can achieve different dimensions of priority. Under this combination of priorities, the production project priority can be considered first, followed by the factory priority, and then the material priority. This can better adapt to complex actual production scenarios and meet different priority consideration orders.

[0090] Step 309, combining the production constraint information, the inventory warehouse location restriction information and the maximum supply restriction information, adjusts the inventory of materials to be allocated for each production project until the total shortage of materials is minimized and the total amount of material demand inventory allocation business is maximized.

[0091] In a possible implementation, the total understock amount can be minimized by the following formula:

[0092]

[0093] Since the production project with a higher priority is assigned a greater weight value, if the production project with a higher priority is out of material, the total amount of material out of stock M will be larger, so it is necessary to allocate materials to the production projects with higher priority first to minimize the total amount of material out of stock.

[0094] The total amount of material demand inventory allocation business can be maximized by the following formula:

[0095]

[0096] It should be noted that the order of meeting the production items is given in the step of minimizing the total shortage of materials. In addition, the order of factories and the order of meeting the priority of materials can be further refined. Therefore, on the basis of minimizing the total shortage of materials, the priority order of different dimensions can be achieved by maximizing the total amount of material demand inventory allocation business, that is, the production project priority is considered first, followed by the factory priority, and finally the material priority.

[0097] Step 310: determine the adjusted inventory of materials to be allocated for each production item as material demand inventory allocation information.

[0098] In the embodiments of the present disclosure, steps 301 to 305 may be implemented in any manner in the embodiments of the present disclosure, and the embodiments of the present disclosure do not limit this and will not be described in detail.

[0099] By implementing the embodiments of the present disclosure, the constraints of production constraint relationship information, inventory warehouse location restriction information, and maximum supply restriction information are comprehensively considered, and the minimization of the total shortage of materials and the maximization of the total amount of material demand inventory allocation business are taken as the business logic requirements that need to be met. The priorities of factories, materials, and production projects are combined to determine the material demand inventory allocation information. The embodiments of the present disclosure can realize the priority order of different dimensions, which can better adapt to complex actual production scenarios and meet different priority consideration orders. It is suitable for production scenarios with multiple warehouses and multiple factories, and can more accurately allocate material inventory. It can also reduce the stagnation of materials, further improve the material demand satisfaction rate and material management efficiency, and optimize the material demand inventory allocation process.

[0115] Where N is the total amount of material demand inventory allocation business, Wj is the priority of the jth production item, U l is the priority of the lth factory, V i is the priority of the ith material, x i,j,l is the inventory of materials to be allocated for the jth production item.
