Description

Technical Field

[0001] The present invention relates to the technical field of material supply, and particularly to a material procurement allocation method, system, and storage medium. Background Art

[0002] In modern supply chain management systems, precise control of the procurement ratio is crucial for ensuring the smooth production process and optimizing material inventory. However, in actual business scenarios, especially in complex environments involving KD (Knocked Down) operations, correcting the procurement ratio faces a series of challenges.

[0003] In the KD business model, enterprises usually disassemble products into multiple components or loose parts for procurement and storage, so as to assemble them when needed. This business model increases the complexity of material management because the procurement ratios between different components may be affected by various factors, including but not limited to market demand, production plans, and supply chain stability.

[0004] Specifically, when an enterprise conducts material procurement according to a certain procurement ratio, the introduction of KD operations may lead to an imbalance in the procurement ratio. Especially when placing a large order for a large quantity of KD parts of a certain material, correcting according to the procurement ratio may result in the corrected quantity of other materials far exceeding the actual demand. In this case, if the current actual demand is much lower than the corrected procurement quantity, there may be a problem that some materials are over-corrected, while other materials cannot be ordered due to insufficient corrected quantity.

[0005] This imbalance in the procurement ratio not only affects the stability of the supply chain but also may lead to overstocking and waste of material inventory, increasing the operating costs of the enterprise. Therefore, how to achieve reasonable correction of the procurement ratio in the KD business scenario, ensure the balance of material procurement, and the stability of the supply chain has become an urgent problem to be solved in current supply chain management and procurement strategies.

[0025] The present invention will be described in detail below in conjunction with the specific implementation manners shown in the accompanying drawings. However, these implementation manners do not limit the present invention, and any structural, method, or functional transformation made by those of ordinary skill in the art based on these implementation manners is included in the protection scope of the present invention.

[0026] It should be noted that the term "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article, or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article, or device. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0027] As Figure 1 shown, an embodiment of the present invention provides a method for material procurement and allocation, including but not limited to the following steps.

[0028] Step S1, obtaining the preset procurement ratios of N kinds of materials for preparing the target product.

[0029] Step S2, when it is determined that M kinds of directly sold materials are included in the N kinds of materials, obtaining the total demand for the other N - M kinds of materials.

[0030] Step S3, according to the procurement ratios between the total demand and the N - M kinds of materials in the preset procurement ratios, determining the actual procurement ratios between the N - M kinds of materials so that the sum of the ratio values of the N - M kinds of materials matches the actual demand.

[0031] In this way, by obtaining the preset procurement ratios of N kinds of materials for preparing the target product, and when it is determined that M kinds of directly sold materials are included in the N kinds of materials, obtaining the total demand for the other N - M kinds of materials, and accordingly adjusting the actual procurement ratios of these materials, this method can more accurately calculate and adjust the procurement ratios of other materials by excluding the influence of directly sold materials on procurement and allocation, thereby ensuring the stability of the supply chain and the balance of material supply, effectively avoiding the problem of unbalanced ratios of materials during the procurement process, and improving the flexibility and accuracy of supply chain management.

[0032] In step S1, the preset procurement ratio refers to the share that different suppliers or different materials should account for in procurement, which is preset by an enterprise based on factors such as business requirements, supplier capabilities, and material characteristics before the procurement activity starts. The preset procurement ratio reflects the relative importance and demand relationship among various materials.

[0033] Specifically, in one embodiment, the preset procurement ratio refers to the ratio of the order quantity that an enterprise issues to several suppliers to the total demand procurement order quantity of the same type in the normal procurement process for preparing a target product. This reflects the order allocation situation of the enterprise among multiple suppliers and is an important indicator for measuring the cooperation degree of suppliers and the effectiveness of procurement strategies.

[0034] In another embodiment, the preset procurement ratio can also refer to the ratio of the order quantity of various materials to the total procurement order quantity when an enterprise procures different materials for preparing a target product. This helps the enterprise optimize material inventory management and ensure a balanced supply of materials required for production.

[0035] In the above embodiments, the materials corresponding to the preset procurement ratio can be the procurement quantity ratio of N essential materials required for preparing a certain target product, or the procurement quantity ratio of the main material and substitute materials when preparing a certain target product. The present invention does not make specific limitations on this.

[0036] For example, assume that three materials, namely material A, material B, and material C, are required for preparing a certain target product, and their corresponding procurement ratio is A:B:C = 30:65:5. This procurement ratio can be understood as for every 100 units of the target product, 30 units of material A, 65 units of material B, and 5 units of material C need to be procured. It can also be understood that material A and material B can be regarded as the main materials for preparing the target product, while material C is regarded as a substitute material or spare material. Under normal circumstances, the procurement quantities of the main materials A and B are relatively large, accounting for 30% and 65% of the total procurement quantity respectively, while the procurement quantity of the substitute material C is relatively small, only accounting for 5%.

[0037] In step S2, direct-sale materials refer to materials that can be directly sold to customers. These materials may be finished products, semi-finished products, or components, including at least one of direct selling and selling. In supply chain management, direct-sale materials have clear sales targets and sales channels, and their procurement and inventory management are relatively independent, but they will have a greater impact on the procurement ratio of other materials for preparing the target product.

[0038] In the present invention, direct-sale materials can be understood as a specific form of KD business, specifically referring to KD materials imported in bulk or disassembled state. KD business can include at least one of SKD (Semi-Knocked Down) and CKD (Completely Knocked Down). SKD refers to imported core components, modules and other electronic parts, which are partially assembled in China to form a complete product; while CKD refers to imported equipment entering in a completely disassembled state, and domestic manufacturers need to receive these spare parts and perform detailed assembly and integration to form the final product.

[0039] In the KD (knockdown) business, companies need to purchase various parts from multiple suppliers and assemble them domestically. In order to reduce logistics costs and improve assembly efficiency, companies may tend to purchase a large amount of KD materials at one time to maintain the continuity and stability of the supply chain during the assembly process.

[0040] Based on this, the purchase volume of direct-sale materials is often large. In order to maintain the original purchase ratio, the purchase quantity of other materials will be calculated and revised. However, when this correction is too large, and the current actual demand is far less than this corrected quantity, a problem will arise: when trying to balance the ratio by increasing the purchase volume of other materials, due to limited actual demand, these additional purchase volumes are often unable to be digested, resulting in a continuous imbalance in the purchase ratio. Even when this imbalance persists, it may lead to a long period of time without new purchase orders for a certain material, which in turn affects the stability of the entire supply chain and the production efficiency of the enterprise.

[0041] For example, let's continue with the purchase ratio of A:B:C=30:65:5 (N=3). Assuming that in the KD business scenario, material C (M=1) is a direct-sale material, and the corresponding designated order material C is 1000k, in order to maintain this purchase ratio, the purchase quantities of material A and material B are revised. The revised quantity of material A is 1000k / 5*30=6000k, and the revised quantity of material B is 1000k / 5*65=13000k. At this time, the revised purchase quantities (6000k and 13000k) are calculated based on the designated order quantity of material C (1000k) and the preset ratio, and they do not represent the actual demand at present or in the future. When the actual demand (for example, the total demand for material A and material B is 10k) is much lower than the revised purchase quantity, material A will be purchased first to meet this larger revised purchase quantity, which may cause the actual order quantity of material B to be shelved or postponed for a long time, resulting in an imbalance in the ratio between material A and material B.

[0042] In step S3, the actual demand refers to the actual demand of the target product. The actual demand of each material is determined based on the actual demand and the BOM (Bill of Materials) information for preparing the target product. The purchase ratio between the NM materials is determined based on the actual demand of each material in the NM materials. In other words, for the NM materials, no matter how many specific types there are (such as 3 or 2), the purchase ratio between them is allocated according to their respective actual demand, but the sum of these ratios is always 100% (or can be converted to any sum, 100% is easy to understand). Therefore, if there are 3 materials, the purchase ratio between them may be 20%: 30%: 50%; and if there are 2 materials, the corresponding ratio may be 40%: 60%.

[0043] In step S3, "the sum of the proportion values matches the actual demand" means that when purchasing NM types of materials according to the actual purchasing proportion determined above, the total amount of these materials should just meet the overall demand calculated in step S2.

[0044] like Figure 2 As shown, in one embodiment, step S2 of the present invention may specifically include the following steps.

[0045] Step S21, when it is determined that N materials include M direct-sale materials, the current purchase quantity of the M direct-sale materials is also obtained, and the target purchase quantity of the other NM materials is determined according to the current purchase quantity of the M direct-sale materials and the ratio between the NM materials in the preset purchase ratio.

[0046] Step S22: determining the actual purchase ratio among the NM materials according to the total demand for the NM materials and the target purchase quantity of the NM materials.

[0047] In this way, by first determining the purchase quantity of directly sold materials, and then using this as a basis to estimate the purchase quantity of other materials, the purchase quantity can be determined according to the proportional relationship between materials. This will help to achieve a reasonable allocation of resources and avoid over-purchasing of some materials and shortages of other materials.

[0048] The target purchase quantity makes the ratio between NM materials and M materials meet the preset purchase ratio; the relationship between the target purchase quantities of NM materials indicates the proportional relationship between the NM materials. In other words, in each purchase process, the actual purchase ratio is close to or equal to the preset purchase ratio.

[0049] In step S21, the overall demand refers to the total quantity of all N-M materials that are demanded. The target purchase quantity is the quantity that should be purchased for the N-M materials theoretically calculated based on the preset purchase ratio and the purchase quantity of the M direct-sale materials. In other words, it reflects the expected purchase quantity set for the N-M materials in an ideal situation to meet the overall demand.

[0050] In a specific embodiment, the M direct-sale materials include the first direct-sale material. The step of determining the target purchase quantity of the other N-M materials according to the ratio between the current purchase quantity of the M direct-sale materials and the N-M materials in the preset purchase ratio may specifically include the following steps.

[0051] Step S211, according to the ratio relationship between each of the N-M materials and the first direct-sale material in the preset purchase ratio, determine the corresponding number of ratio values.

[0052] Step S221, obtain the current purchase quantity of the first direct-sale material, and calculate the product of each ratio value and the current purchase quantity respectively to obtain the target purchase quantity of each of the N-M materials.

[0053] In this way, by correcting the purchase quantity of the N-M materials, the target purchase quantity of them can be kept in a preset ratio relationship with the current purchase quantity of the direct-sale materials, ensuring that they can meet the actual demand for producing the target product and guaranteeing the continuity and stability of production.

[0054] As Figure 3 shown, in an embodiment, step S3 of the present invention may specifically include the following steps.

[0055] Step S31, determine whether the overall demand of the N-M materials is less than the target purchase quantity of the N-M materials, and / or determine whether the overall demand of the N-M materials is less than the sum of the target purchase quantities of the N-M materials.

[0056] If so, jump to step S32A, allocate the overall demand of the N-M materials according to the relationship between the target purchase quantities of the N-M materials to obtain the actual purchase quantity of the N-M materials, and determine the actual ratio according to the relationship of the actual purchase quantities.

[0057] If not, jump to step S32B, and complete the complete set quantity of the historical purchases of some of the N-M materials according to the remaining complete set quantity of the historical purchases of each of the N-M materials and the purchase ratio between the N-M materials to obtain the actual purchase quantity of the N-M materials, and determine the actual ratio according to the relationship of the actual purchase quantities.

[0058] Thus, according to the comparison result between the total demand and the target purchase quantity of N - M materials, the actual purchase quantity of N - M materials is intelligently adjusted, and a reasonable proportional relationship is ensured among the actual purchase quantities.

[0059] In other embodiments, it is also possible to determine whether the demand for at least one of the N - M materials is less than the target purchase quantity of the corresponding material; if so, according to the relationship between the target purchase quantities of the N - M materials, the total demand of the N - M materials is allocated to obtain the actual purchase quantities of the N - M materials, and the actual ratio is determined according to the relationship of the actual purchase quantities.

[0060] For the sake of facilitating the understanding of the above steps S31 to S32A, for example, assume that the preset purchase ratio of three materials (i.e., N = 3) for preparing the target product is A:B:C = 30:65:5. In the KD scenario, the current purchase quantity of material C (direct - sale material) is specified as 1000k. Based on the purchase ratios of the other materials (i.e., materials A and B) in the preset purchase ratio (A:B = 30:65), the target purchase quantities of materials A and B are determined to be 6000k and 13000k respectively.

[0061] If the total demand for materials A and B is 10k, then according to the target purchase quantities and the total demand, the actual purchase ratio of materials A and B is calculated. That is . The total demand of 10k is split, and the purchase quantity of material A is 3158, and the purchase quantity of material B is 6842, thus avoiding the occurrence of the phenomenon of unbalanced material purchase ratio.

[0062] As Figure 4 shown, in a specific embodiment, before step S32B, the method may further include the following steps.

[0063] Step P31, obtaining the historical purchase quantity and the corresponding unit usage amount of each of the N - M materials for preparing the target product.

[0064] Step P32, calculating the historical purchase quantity and the corresponding unit usage amount to determine the remaining complete - set quantity of the historical purchase of this material.

[0065] Thus, by obtaining the historical purchase quantity and the corresponding unit usage amount of the N - M materials, the past purchase and usage situations of each material can be comprehensively understood, and these data can be used to evaluate the remaining quantity available for future production after each material meets the production demand.

[0066] In step P31, the historical purchase quantity refers to the total quantity of materials actually purchased by an enterprise for preparing the target product over a past period. The unit consumption refers to the quantity of a certain material required for preparing a unit quantity of the target product, which can be expressed in measurement units such as weight, volume, or quantity. For example, if preparing one target product requires one material A and two materials B, then the unit consumption of material A is 1, and the unit consumption of material B is 2.

[0067] Understandably, in the actual procurement process, due to various factors in the procurement, transportation, storage, and preparation processes, it is difficult to ensure that the purchase quantity of each material can precisely match the preparation requirements of the target product. Therefore, over-purchase or under-purchase of materials may occur. Based on this, in step P32, the remaining complete set quantity of historical purchases refers to the quantity of materials remaining after meeting the preparation requirements of the target product in a certain period or batch.

[0068] For example: Assume that material A and material B are key materials for preparing a certain target product, and the ratio between them is 1:1 (i.e., for each unit of the target product prepared, 1 unit of material A and 1 unit of material B are required). In a certain historical purchase, 4k of material A and 4k of material B were purchased. However, due to production adjustments or changes in market demand, only 2k of material A and 4k of material B were actually used. In this case, the remaining 2k of material A and 0k of material B constitute the "remaining complete set quantity of historical purchases".

[0069] As Figure 5 shown, in a specific embodiment, the step of supplementing the complete set quantity of historical purchases of some of the N - M materials according to the remaining complete set quantity of historical purchased materials of each of the N - M materials and the purchase ratio between the N - M materials in step S32B to obtain the actual purchase quantity of the N - M materials may specifically include the following steps.

[0070] Step S321: According to the purchase ratio between the N - M materials and the maximum value of the remaining complete set quantity of historical purchases among the N - M materials, supplement the complete set quantity of historical purchases of the remaining materials to obtain the total sum of the required complete set quantity to be supplemented for the N - M materials.

[0071] Step S322: When the total demand for the N - M materials is greater than the total sum of the required complete set quantity to be supplemented, allocate the remaining total complete set quantity of the N - M materials according to the purchase ratio between the N - M materials, where the remaining total complete set quantity is equal to the difference between the total demand and the total sum of all required complete set quantity to be supplemented.

[0072] Step S323: Determine the actual purchase quantity of the N - M types of materials based on the allocation result of the quantity to be supplemented for the N - M types of materials and the remaining overall kit quantity of the corresponding N - M types of materials.

[0073] In this way, by comprehensively considering the purchase quantity of historical materials, the purchase quantity of the current batch of materials is adjusted, aiming to gradually make the purchase ratio among the N - M types of materials purchased this time approach the preset purchase ratio and ensure the balance of each material during the purchase process.

[0074] In step S321, the kit quantity refers to the ratio and total quantity that the quantities of various materials should reach in order to ensure the preparation or production of a certain quantity of complete products during one purchase or production process. In other words, in a group of materials, each material is purchased or prepared according to a preset ratio to meet the requirements for producing one or more complete target products.

[0075] In step S321, the quantity to be supplemented for the kit refers to the quantity of materials among the N - M types of materials that have not reached the kit state (i.e., are completely matched according to a certain ratio and quantity) for meeting the production or preparation of the target product.

[0076] For example, assume that material A and material B are key materials for preparing a certain target product, and the ratio between them is 1:2. If the maximum remaining kit quantity of historical purchases for material A is 2k, and the remaining kit quantity of historical purchases for material B is 0, then material B is supplemented, and the corresponding quantity to be supplemented for the kit is 4k, while the quantity to be supplemented for the kit corresponding to material A is 0. Therefore, the overall quantity to be supplemented for the kit is 0 + 4k = 4k.

[0077] In a specific embodiment, step S323 of the present invention may further specifically include the following steps.

[0078] Step S3231: Calculate the sum of the allocation result of the remaining overall kit quantity of each of the N - M types of materials and the corresponding quantity to be supplemented for the kit, and obtain the total required kit quantity for the corresponding material.

[0079] Step S3232: Calculate the product of the unit usage of each of the N - M types of materials and the corresponding total required kit quantity, and determine the actual purchase quantity of each of the N - M types of materials.

[0080] In this way, by calculating the sum of the allocation results of the remaining overall complete sets of quantities and the required complete sets of quantities to be supplemented, and determining the actual purchase quantity of each material based on the unit usage of each material and this sum, on the one hand, the materials purchased in excess in the past can be fully utilized, reducing inventory backlogs and material waste; on the other hand, it can ensure that the quantity of materials purchased this time matches the production plan, avoiding production interruptions or material shortages caused by unbalanced materials.

[0081] To facilitate the understanding of determining the actual purchase quantity of each of the N - M materials based on the remaining complete sets of quantities of the historical purchased materials, for example. The materials required to prepare the target product M are two units of material A and one unit of material B respectively. There are multiple suppliers for material A. Suppose the proportion of material A (let's define it as material A1) provided by supplier 1 is 10, the proportion of material A (let's define it as material A2) provided by supplier 2 is 20, and the proportion of material B provided by supplier 1 is 30. In addition, the demand quantity (i.e., the overall demand quantity) of the target product M is 16k, and the historical over - ordered quantities of material A1, material A2, and material B are 0, 4k, and 0 respectively.

[0082] Based on the historical over - ordered quantities of material A1, material A2, and material B being 0, 4k, and 0 respectively, and the unit usage of each material for preparing the target product M, the remaining complete sets of quantities of material A1, A2, and B are obtained as 0, 4k / 2k = 2, and 0 respectively; taking the maximum value of the remaining complete sets of quantities as the reference standard for the replenishment operation, that is, the maximum value of the remaining complete sets of quantities of the historical purchased materials is 2k.

[0083] According to the proportions of material A1, material A2, and material B (10:20:30) and the maximum value of the remaining complete sets of quantities, the historical complete sets of quantities of the remaining materials (A1 and B) are replenished to obtain the required complete sets of quantities to be supplemented, that is, 1k for material A1, 0 for material A2, and 6k for material B.

[0084] After replenishing the historical complete sets of quantities of the remaining materials, calculate the difference between the demand quantity of the target product and the sum of the required complete sets of quantities to be supplemented to obtain the remaining net required complete sets of quantities (i.e., the remaining overall complete sets of quantities) of the target product M, that is, 16k - (1k + 6k) = 9k. Allocate the remaining overall complete sets of quantities (9k) according to the purchase proportions of material A1, material A2, and material B (10:20:30), and the allocation results of material A1, material A2, and material B are 1k, 2k, and 6k respectively.

[0085] Calculate the sum of the allocation results of Material A1, Material A2, and Material B and the corresponding quantity of the demand to be completed to obtain the total quantity of the demand to be completed for the corresponding material. That is, the total quantity of the demand to be completed for Material A1 is 1k + 1k = 2k, the total quantity of the demand to be completed for Material A2 is 0 + 2k = 2k, and the total quantity of the demand to be completed for Material B is 6k + 6k = 12k.

[0086] Based on the unit usage of Material A1 and Material A2 being 2, and the unit usage of Material B being 1, the actual purchase quantity of Material A1 is 2 * 2k = 4k, the actual purchase quantity of Material A2 is 2 * 2k = 4k, and the actual purchase quantity of Material B is 1 * 12k = 12k. Therefore, the actual purchase ratio among Material A1, Material A2, and Material B is A1:A2:B = 4k:4k:12k = 1:1:3, and this actual purchase ratio is also the ratio set for this purchase order.

[0087] In an embodiment of the present invention, a material procurement and allocation system is provided.

[0088] The material procurement and allocation system can adopt a material procurement and allocation method for determining the actual purchase ratio of multiple materials used to prepare a target product.

[0091] The material procurement and allocation system includes a second module. The second module is used to determine the actual purchase ratio among the N - M materials according to the purchase ratio between the total demand and the N - M materials in the preset purchase ratio, so that the sum of the ratio values of the N - M materials matches the actual demand.

[0092] In an embodiment of the present invention, a computer-readable storage medium is provided.

[0093] In one embodiment, the computer-readable storage medium stores a computer program executed by the foregoing-mentioned processor, or the material procurement and allocation method in any of the foregoing technical solutions.
