However, the transportation cycle of materials from the storage site used to store materials to the demand sites located in different regions and available for use is different. For example, the transportation cycle from the storage site to the demand site closer to the storage site is generally available on the same day, while the transportation from the storage site to the demand site far away from the storage site requires transportation and even quality inspection before it can be used at the corresponding demand site, that is, the transportation from the storage site to the demand site far away from the storage site and can be used requires a longer transportation cycle, resulting in that the complete set result of the demand site far away from the storage site calculated by the traditional material pre-allocation method may not be realized from the perspective of actual execution, that is, the materials allocated to the demand site far away from the storage site cannot arrive at the demand site at the actual demand time of the demand site and cannot be used, and the demand site far away from the storage site cannot perform complete production at the actual demand time, resulting in the calculation being inconsistent with the actual situation.

BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Figure 1 is a flow chart of the material pre-distribution method of the present invention;

[0031] Figure 2 for Figure 1 The steps in the flowchart are used to pre-allocate materials according to the obtained supply quantity. DETAILED DESCRIPTION

[0032] The present invention will be described in detail below in conjunction with the various embodiments shown in the accompanying drawings. Figure 1-Figure 2 It is shown as a preferred embodiment of the present invention. However, the following embodiments are only used to illustrate the present invention but are not used to limit the scope of the present invention.

[0033] Please refer to Figure 1~2 As shown, the present invention provides a material pre-allocation method, which is used to obtain the material pre-allocation amount of each demand site at a preset time in the future, such as the material pre-allocation amount of each demand site in each month in the next 6 months, wherein the material pre-allocation amount of each demand site in each month can be allocated according to the material pre-allocation method. On the one hand, it can ensure that the materials required in the production process of each demand site can be used for complete production at the appropriate time and place, reduce production waiting time, and improve the efficiency and capacity of the production line; on the other hand, it can also facilitate customers to adjust production plans in time according to the obtained material pre-allocation amount and communicate effectively with customers in time to ensure timely delivery and improve customer satisfaction.

[0034] It can be known that the material pre-allocation method in the present invention obtains the material pre-allocation quantity of each demand site at the planning level; in the actual allocation process, the material pre-allocation quantity of each demand site can be coordinated to a certain extent according to the specific circumstances (such as the production plan of the demand site, the urgency of each order, etc.).

[0035] At the same time, for the various materials required for complete set production, generally only important materials (such as chips, screens, cameras, etc.) need to be purchased from storage sites, and other general materials (such as fastening screws, etc.) can be directly purchased locally according to demand to reduce procurement costs. That is, only important materials will be pre-allocated using this material pre-allocation method.

[0036] Specifically, combined Figure 1 As shown, the material pre-distribution method comprises the following steps:

[0037] Get the actual demand time t of the demand site for the demand material 实 ;

[0038] Get the transportation cycle t that can be used to transport materials from the storage site to the demand site 运 ;

[0039] According to the actual demand time t 实 And the transportation cycle t 运 Get the pulling demand time t after pulling 提 ,in, ;

[0040] According to the pulling demand time t 提 The supply quantity is obtained, and material pre-allocation is performed on the obtained supply quantity.

[0041] It is known that the supply includes the amount of materials in stock at the storage site and the amount of materials in stock at the pull demand time t 提 The amount of materials in transit that could be transported to the storage site and the expected material production volume.

[0042] In the material pre-allocation method of the present invention, the amount of materials in transit and the expected material production volume are taken into account when pre-allocating materials, and the transportation cycle t of materials from the storage site to each demand site is also taken into account. 运 The impact on the actual available time of materials, based on the actual demand time t 实 And the transportation cycle t 运 The actual demand time t 实 Perform lifting, according to the lifting demand time t after lifting 提 Pre-sorting to reduce the transportation cycle t corresponding to each demand site 运The impact on the time point of full-set production at the demand site makes material distribution more fair, can provide more accurate full-set calculation results, better match the actual demand situation, improve the accuracy of order fulfillment, and enhance the reliability of production plans.

[0043] Specifically, the actual required time t 实 It refers to the time when the corresponding demand site needs to use the material for complete production; the above-mentioned pull demand time t 提 This means that the demand site can be 实 The latest delivery time for the storage site that carries out complete set production.

[0044] In one embodiment, the transport period t 运 It refers to the time it takes for materials to be transported from the storage site to the demand site, that is, it is assumed that materials can be used for complete production after being transported from the storage site to the demand site. Of course, this is not limited to this. In other embodiments, the transportation cycle t 运 It can also include the transportation time of materials from the storage site to the demand site and the quality inspection time, that is, after the materials are transported from the storage site to the demand site, they still need to undergo quality inspection and other processes before they can be used for complete production.

[0045] It can be seen that the transportation cycle t corresponding to a certain demand station 运 is a variable value, specifically, the transport period It may be affected by the transportation transit time and inspection time, for example, the transportation transit time of ordinary logistics is longer than that of expedited logistics. When the material pre-allocation quantity Q obtained by the material pre-allocation method at a certain demand site cannot meet the full set production, the user can communicate with the logistics company to replace the original ordinary logistics with the updated transportation cycle t corresponding to the expedited logistics 运 , and the updated transport cycle t 运 Substitute the material into the material pre-allocation method to re-perform material pre-allocation, so that the user can compare multiple material pre-allocation results to obtain a better material pre-allocation result.

[0046] Furthermore, the number of demand sites is not less than 2. In this case, the obtained supply quantity needs to be pre-allocated among the demand sites to obtain the material pre-allocation quantity Q of each demand site. It can be seen that if the number of demand sites is only 1, then the material pre-allocation of the obtained supply quantity is to pre-allocate the obtained supply quantity according to the material demand quantity of the demand site.

[0047] In a specific implementation of the number of demand sites being no less than 2, Figure 2 As shown, “pre-allocating materials according to the obtained supply quantity” specifically includes the following steps:

[0048] Get the material demand D of each demand site and sum them up to get the total demand D 总 ;

[0049] Obtain the inventory balance S of each demand site, and sum the inventory balance S of each demand site and the supply quantity to obtain the total supply quantity S 总 ;

[0050] According to the total supply S 总 And the total demand D 总 Get the supply-demand ratio S 总 / D 总 ;

[0051] According to the supply-demand ratio S 总 / D 总 , calculate the material pre-allocation quantity Q of each demand site;

[0052] The material pre-allocation quantity Q of the i-th demand site i The calculation formula is as follows: i =D i *S 总 / D 总 -S i , where i is the i-th demand site, i=1, 2, ... n, n means there are n demand sites, D i is the material demand of the i-th demand site, S i is the inventory surplus of the i-th demand site.

[0053] Specifically, the total demand D 总 =D1+ D2+…+ D n Total supply S 总 = S1+ S2+…+ S n +ATP.

[0054] In the present invention, when pre-allocating the obtained supply, the total demand D is considered. 总 , the inventory balance S and supply of each demand site, based on the total supply-demand ratio S 总 / D 总 Allocate in proportion so that the pre-allocated amount Q of materials to each demand site is relatively balanced, ensuring fair distribution of materials.

[0055] Specifically, the material demand of each demand site can be calculated based on the previously preset demand to estimate the material demand of the site. In a specific implementation, the material demand D of the i-th demand site in month M is iMIt is the sum of the preset demand of (M-3) month * 0.6, the preset demand of (M-2) month * 0.3, and the preset demand of (M-1) month * 0.1, that is, D i =D i（M-3） *0.6+ D i（M-2） *0.3+ D i（M-1） *0.1. Of course, this is not the limit.

[0056] It can be seen that although the supply-demand ratio S 总 / D 总 S 总 When the inventory surplus S of each demand site is counted in S 总 However, the inventory balance S of each demand site belongs to non-allocatable materials, and only the materials corresponding to the supply quantity belong to allocable materials, that is, the materials will not be transported and allocated between different demand sites to avoid increasing unnecessary transportation costs.

[0057] Further, in “according to the supply-demand ratio S 总 / D 总 After calculating the material pre-allocation quantity Q" of each demand site, the material pre-allocation method further includes the following steps:

[0058] Determine whether there is a demand site with a material pre-allocation quantity Q≤0. If so, eliminate the demand site with the material pre-allocation quantity Q≤0, and re-pre-allocate materials to the remaining other demand sites according to the obtained supply quantity.

[0059] It can be seen that if the material pre-allocation quantity Q of a demand site is less than or equal to 0, it means that according to the supply-demand ratio S 总 / D 总 The calculated D*S of the demand site 总 / D 总 is less than or equal to the inventory balance S of the demand site itself, that is, there is no need to allocate materials to the demand site in the calculated allocable material supply. At this time, the demand site is eliminated, and the remaining other demand sites are re-pre-allocated materials according to the specific steps of "pre-allocating materials according to the obtained supply" so that the material pre-allocation quantity Q of each demand site is relatively balanced and more accurate.

[0060] Furthermore, the actual required time t 实 And the pulling time t 提 The unit is day; "According to the pulling demand time t 提 Obtaining the supply quantity is specifically as follows: according to the pulling demand time t 提The supply quantity corresponding to the time period is obtained for the time period, and the supply quantity is the sum of the initial inventory quantity (the quantity of materials in stock) of the storage site, the quantity of materials in transit that can be transported to the storage site within the time period, and the expected material production quantity. That is, the material pre-allocation method in the present invention allocates the supply quantity of a time period to the demand site that needs materials within the time period, which can simplify the material pre-allocation method and improve the material pre-allocation efficiency.

[0061] In a specific implementation, the time period is in months. For example, the actual demand time t of a demand site 实 For October 3, 2024, if the transportation period is t 运 is 3 days, and the corresponding lifting demand time t 提 If the delivery date is September 30, 2024, the demand station is allocated the supply for the entire month of September. 运 is 2 days, and the corresponding lifting demand time t 提 If the date is October 1, 2024, the demand site is allocated the supply for the entire month of October. Of course, this is not limited to this. In other implementations, the time period can also be in weeks, or part of the time period can be in weeks and part of the time period can be in months. For example, when predicting the material pre-allocation amount for the next 6 months, for a relatively recent time, the time period is in weeks, such as within 13 weeks, which can be the predicted material pre-allocation amount for each week in the next 13 weeks; for a relatively distant time, such as after 13 weeks, the time period can be in months.

[0062] Further, in "according to the pulling demand time t 提 Obtaining the supply quantity is specifically as follows: according to the pulling demand time t 提 In an implementation manner of obtaining a supply amount corresponding to a time period, after performing material pre-allocation according to the obtained supply amount to obtain a material pre-allocation amount for each demand site, the material pre-allocation method further comprises the following steps:

[0063] Determine the storage time and transportation cycle t corresponding to the material pre-allocation quantity of the demand site 运 Whether the sum meets the actual demand time t of the demand site 实 .

[0064] It is known that in the material pre-allocation method, the supply is allocated within a time period, which includes the amount of in-transit materials that have not yet been put into storage and the expected material production. However, the demand time t 实 is a fixed date. If the material pre-allocation quantity of the demand site corresponds to the storage time and the corresponding transportation cycle t 运The sum is later than the actual demand time t of the demand site 实 , it means that the material pre-allocation quantity of the demand site cannot meet the actual demand time t corresponding to the demand site 实 , the demand site cannot produce the entire set as planned. At this time, the demand site can communicate effectively with the customer to adjust the production plan, or communicate effectively with the logistics company corresponding to the amount of materials in transit or the manufacturer corresponding to the expected material production volume to see if they can be put into storage in advance, or communicate with the logistics company that transports the materials from the storage site to the demand site to see if the transportation cycle can be adjusted. 运 , if the transport cycle t can be adjusted 运 , then according to the updated transportation cycle t 运 Re-determine the storage time and transportation cycle t corresponding to the material pre-allocation quantity of the demand site 运 Whether the sum meets the actual demand time t of the demand site 实 , or the updated transport cycle t 运 Substitute it into the material pre-allocation method to re-allocate materials. If the material pre-allocation quantity of the demand site corresponds to the storage time and the corresponding transportation cycle t 运 The sum is no later than the actual demand time t of the demand site 实 , that is, the storage time corresponding to the material pre-allocation quantity of the demand site and the corresponding transportation cycle t 运 The sum is earlier than or equal to the actual demand time t of the demand site 实 , it means that the material pre-allocation quantity of the demand site can meet the actual demand time t corresponding to the demand site 实 , the demand site is able to carry out complete production as planned.

[0065] In a specific implementation, the demand site includes a first regional factory and a second regional factory located in different regions. The transportation period for materials to be transported from the storage site to the first regional factory and available for use is available on the same day, while the transportation period for materials to be transported from the storage site to the second regional factory and available for use is longer and not available on the same day. That is, the first regional factory is closer to the storage site, while the second regional factory is farther away from the storage site. At this time, for the first regional factory, its actual demand time is and the lifting demand time t 提 To reduce logistics and transportation costs.

[0066] Furthermore, the present invention also provides a material pre-distribution device, which comprises at least an information acquisition module, an ATP pre-calculation module, and a pre-distribution module. The information acquisition module is used to obtain the actual demand time t of the material by the demand site of the demand material. 实And the transportation cycle t that materials can be transported from the storage site to the demand site and can be used 运 The ATP pre-calculation module calculates the actual demand time t 实 And the transportation cycle t 运 According to t 提 =t 实 -t 运 Calculate the required time t after pulling 提 , and then according to the pulling demand time t 提 The supply quantity is calculated. The pre-allocation module is used to pre-allocate materials according to the obtained supply quantity.

[0067] Furthermore, the information acquisition module is also used to obtain the material demand D of each demand site and the inventory balance S of each demand site. The pre-allocation module first sums the material demand D of each demand site to obtain the total demand D 总 , sum up the inventory balance S of each demand site and the supply quantity to obtain the total supply quantity S 总 , and then based on the total supply And the total demand D 总 Get the supply-demand ratio S 总 / D 总 , and then according to the material pre-allocation quantity Q of the i-th demand site i The material pre-allocation quantity Q of the i-th demand site is calculated by the calculation formula i Among them, the material pre-allocation quantity Q of the i-th demand site i The calculation formula is as follows: i =D i *S 总 / D 总 -S i , where i is the i-th demand site, i=1, 2, ... n, n means there are n demand sites, D i is the material demand of the i-th demand site, S i is the inventory surplus of the i-th demand site.

[0068] Furthermore, the material pre-allocation device also includes a judgment module, after the pre-allocation module calculates the material pre-allocation quantity Q of each demand site, it feeds back to the judgment module, the judgment module determines whether there is a demand site with a material pre-allocation quantity Q≤0, and if so, feeds back to the pre-allocation module, the pre-allocation module eliminates the demand site with a material pre-allocation quantity Q≤0, and recalculates the remaining other demand sites according to the obtained supply quantity to re-pre-allocate materials.

[0069] Furthermore, after the pre-allocation module calculates the material pre-allocation amount Q of each demand site and feeds it back to the judgment module, the judgment module will also judge whether the material pre-allocation amount of each demand site meets the corresponding pulling demand time t of each demand site. 提 .
