[0036] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The following will describe the present application in detail with reference to the accompanying drawings and in combination with the embodiments.

[0037] Figure 1 FIG. 100 shows an exemplary system architecture where the replenishment quantity determination method or device according to the present disclosure can be applied.

[0038] As Figure 1 shown in FIG. 100, the system architecture 100 may include terminal devices 101, 102, 103, a network 104, and a server 105. The network 104 is used to provide a medium for communication links between the terminal devices 101, 102, 103 and the server 105. The network 104 may include various connection types, such as wired, wireless communication links, or fiber optic cables, etc.

[0039] Users can use the terminal devices 101, 102, 103 to interact with the server 105 through the network 104 to receive or send messages, etc. Various communication client applications can be installed on the terminal devices 101, 102, 103, such as shopping applications, warehouse management applications, video applications, live broadcast applications, instant messaging tools, email clients, social platform software, etc.

[0040] Here, the terminal devices 101, 102, 103 can be hardware or software. When the terminal devices 101, 102, 103 are hardware, they can be various electronic devices with a display screen, including but not limited to smart phones, tablet computers, e - book readers, laptop computers, and desktop computers, etc. When the terminal devices 101, 102, 103 are software, they can be installed in the above - listed electronic devices. It can be implemented as multiple software or software modules (for example, multiple software or software modules for providing distributed services), or it can be implemented as a single software or software module. No specific limitation is made here.

[0041] The server 105 can be a server that provides various services, such as a background server that provides support for the terminal devices 101, 102, 103. The background server can analyze and process replenishment instructions, etc., and feedback the processing results (such as the replenishment quantity of the target item) to the terminal devices.

[0042] It should be noted that the replenishment quantity determination method provided by the embodiments of the present application can be executed by the server 105 or the terminal devices 101, 102, 103. Correspondingly, the replenishment quantity determination device can be set in the server 105 or the terminal devices 101, 102, 103.

[0043] It should be understood, Figure 1The numbers of the terminal devices, networks, and servers in [it] are merely illustrative. According to the implementation requirements, there can be any number of terminal devices, networks, and servers.

[0044] Continuing to refer to Figure 2 , a flowchart 200 of an embodiment of the replenishment quantity determination method according to the present application is shown. The replenishment quantity determination method includes the following steps:

[0045] Step 201, in response to determining that the current inventory of the target item is less than the inventory threshold, determine the initial replenishment quantity of the target item.

[0046] In this embodiment, the execution subject of the replenishment quantity determination method (such as Figure 1 the server or terminal device shown) can determine the initial replenishment quantity of the target item when determining that the current inventory of the target item is less than the inventory threshold. Here, the inventory threshold is the safety inventory set for the inventory. If the current inventory is lower than the safety inventory, replenishment is required. In the replenishment quantity and inventory here, the quantity refers to the number of items of the item. One corresponding to the number of items refers to one stock keeping unit (SKU).

[0047] In practice, the above execution subject can determine the initial replenishment quantity of the target item in various ways. For example, the above execution subject can directly obtain the initial replenishment quantity from the local or other electronic devices. In addition, the above execution subject can also use the difference between the inventory threshold and the current inventory as the initial replenishment quantity.

[0048] In some alternative implementation manners of this embodiment, determining the initial replenishment quantity of the target item in step 201 may include: obtaining the target inventory of the target item; determining the difference between the target inventory and the current inventory as the initial replenishment quantity of the target item.

[0049] In these alternative implementation manners, the above execution subject can obtain the target inventory (TI) of the target item and determine the difference between the target inventory and the current inventory. Then, the above execution subject can determine this difference as the initial replenishment quantity of the target item. Here, the target inventory can be preset or determined in real time. For example, the target inventory can be associated with the inventory threshold, such as the sum of the inventory threshold and the inventory consumption of the target number of days.

[0050] In these implementation manners, the above execution subject can accurately determine the initial replenishment quantity by using the target inventory, which helps to determine the accurate actual replenishment quantity.

[0051] In some alternative implementation manners of this embodiment, step 201 may include: obtaining the target inventory quantity of the target item; and determining the difference between the target inventory quantity and the current inventory quantity as the initial replenishment quantity of the target item.

[0052] In these alternative implementation manners, the above-mentioned execution entity may obtain the target inventory quantity and determine the difference between the target inventory quantity and the current inventory quantity. After that, the above-mentioned execution entity may determine this difference as the initial replenishment quantity of the target item.

[0053] These implementation manners can accurately determine the initial replenishment quantity of the target item.

[0054] In some alternative implementation manners of this embodiment, the inventory threshold may be determined through the following steps: determining the product of the delivery days of the target item and the daily average value of the inventory consumption in the target future time period as the first product; determining the product of the normal distribution value corresponding to the probability that the target item can be continuously provided and the standard deviation of the historical inventory consumption of the target item as the second product; and taking the sum of the first product and the second product as the inventory threshold.

[0055] In these alternative implementation manners, the above-mentioned execution entity or other execution entities may determine the inventory threshold. Taking the above-mentioned execution entity as an example, the above-mentioned execution entity may determine the product of the delivery duration and the daily average value of the predicted inventory consumption and use it as the first product. Here, the predicted daily average value may be the ratio of the predicted inventory consumption in the future n days to n, or it may be the inventory consumption obtained for each future day.

[0056] Moreover, the above-mentioned execution entity may also determine the probability that the target item can be continuously provided, that is, the service level, and look up the normal distribution value corresponding to this probability in the normal distribution table. After that, the above-mentioned execution entity may determine the product of this normal distribution value and the standard deviation. Here, the standard deviation may be the standard deviation of the inventory consumption of each day in the target historical time period. For example, the target historical time period may be the just-passed 30 days. The above-mentioned execution entity may obtain the inventory consumption of the target item in these 30 days, remove the maximum value and the minimum value, and calculate the standard deviation of the inventory consumption of the remaining 28 days.

[0057] These implementation manners can determine the inventory threshold based on the historical inventory consumption, which helps to determine a more accurate replenishment quantity.

[0058] In some alternative application scenarios of these implementation manners, the inventory consumption amount of the above-mentioned target future time period can be determined through the following steps: perform regression on the inventory consumption amounts of the first historical time period, the second historical time period, and the third historical time period to determine the regression coefficients corresponding to the first historical time period, the second historical time period, and the third historical time period respectively, where the number of days included in the third historical time period is greater than the number of days included in the second historical time period, and the number of days included in the second historical time period is greater than the number of days included in the first historical time period; generate a regression equation for the inventory consumption amount of the first future time period, including the regression coefficients corresponding to the first historical time period, the second historical time period, and the third historical time period respectively, where the number of days included in the first future time period is the same as the number of days included in the first historical time period; for the target future time period, obtain the inventory consumption amounts of the first historical time period, the second historical time period, and the third historical time period, and determine the inventory consumption amount of the target future time period based on the regression equation and each obtained inventory consumption amount.

[0059] In these alternative implementation manners, the above-mentioned execution entity can obtain the inventory consumption amounts of the first historical time period, the second historical time period, and the third historical time period, and perform regression on these three to obtain the regression coefficients corresponding to these three respectively. After that, the above-mentioned execution entity can determine the regression equation corresponding to the first future time period, where the duration of the first future time period is the same as that of the first historical time period. In this way, the inventory consumption amounts of multiple historical time periods corresponding to the target future time period can be obtained and substituted into the above-mentioned regression equation, so as to predict the inventory consumption amount of the target future time period. Specifically, the above-mentioned execution entity can, for the target future time period, determine the inventory consumption amounts of the first historical time period, the second historical time period, and the third historical time period corresponding to the target future time period respectively, and based on these three inventory consumption amounts and the above-mentioned regression equation, determine the inventory consumption amount of the target future time period.

[0060] For example, for yesterday, the inventory consumption amounts of the historical 7 days (7 consecutive days including the day before yesterday) before yesterday, the historical 14 days, and the historical 28 days can be obtained. After that, perform regression on these three inventory consumption amounts to obtain three regression coefficients α, β, and γ respectively. Generate a regression equation for the inventory consumption amount Y of the future 7 days, which can be expressed as:

[0061] Y = αX 1 + βX 2 + γX 3 ,

[0062] where X1 , X 2 , X 3 are respectively the inventory consumption amounts in the first historical time period, the second historical time period, and the third historical time period. In practice, if it is necessary to predict the inventory consumption amount for the next 7 days today, the inventory consumption amounts for the historical 7 days (7 consecutive days including yesterday) before today, the inventory consumption amounts for the historical 14 days, and the inventory consumption amounts for the historical 28 days can be obtained and used as X 1 , X 2 , X 3 values are substituted into the regression equation to predict the inventory consumption amount for the next 7 days today. In practice, the above-mentioned executing entity can determine the ratio of the inventory consumption amount for the next 7 days to 7 (days) to obtain the daily average value of the inventory consumption amount for the next 7 days.

[0063] Step 202: Obtain the full case quantity of the target item, where the full case quantity is used to indicate the number of pieces of the target item in a full case.

[0064] In this embodiment, the above-mentioned executing entity can obtain the full case quantity of the target item. Here, the full case quantity, that is, the case specification, can indicate the number of pieces of the target item in the case when the case for loading the target item is full.

[0065] Step 203: Based on the full case quantity, compare the replenishment quantity obtained after making up a full case for the initial replenishment quantity with the inventory consumption amount on the first day.

[0066] In this embodiment, the above-mentioned executing entity can determine the replenishment quantity obtained after making up a full case for the initial replenishment quantity based on the full case quantity and compare the size between this replenishment quantity and the inventory consumption amount on the first day. Here, the first day can be a specified number of days. In practice, based on the full case quantity, the above-mentioned executing entity can determine whether the initial replenishment quantity is greater than one case. Specifically, the initial replenishment quantity may be less than one case, and then it is one case after making up a full case. In addition, the initial replenishment quantity may also be greater than one case and not fully make up a full case. In this case, after making up a full case for the initial replenishment quantity, the part that is not a full case is changed to a full case. For example, if the initial replenishment quantity is two and a half cases, and the replenishment quantity for the full cases is two cases, after making up a full case, two and a half cases become three cases, that is, the replenishment quantity obtained after making up a full case is three cases.

[0067] In some scenarios, in order to avoid performing ineffective steps, the above-mentioned executing entity can execute this step 203 in response to the initial replenishment quantity being a non-full case replenishment quantity.

[0068] In practice, the above-mentioned execution entity can compare the obtained replenishment quantity with the inventory consumption quantity on the first day in various ways. For example, the above-mentioned execution entity can determine whether the obtained replenishment quantity is less than or equal to the inventory consumption quantity on the first day. In addition, the above-mentioned execution entity can also determine whether the obtained replenishment quantity is greater than the inventory consumption quantity on the first day.

[0069] Step 204: Based on the comparison result, determine and output the replenishment quantity of the target item.

[0070] In this embodiment, the above-mentioned execution entity can determine the replenishment quantity of the target item based on the comparison result and output it. Specifically, the output executed by the above-mentioned execution entity can be output to other modules in the same electronic device, or can be output to other electronic devices. The replenishment quantity of the target item determined here is the final (determined) replenishment quantity output by the above-mentioned execution entity, and it is also the replenishment quantity to be adopted in practice.

[0071] In practice, the above-mentioned execution entity can determine the replenishment quantity of the target item in various ways. For example, when the obtained replenishment quantity is greater than the inventory consumption quantity on the first day, the execution entity can determine the replenishment quantity of the whole box in the initial replenishment quantity as the replenishment quantity of the target item.

[0072] The method provided by the above embodiment of the present application can accurately determine the replenishment quantity of the target item based on the comparison result between the replenishment quantity after making up a whole box and the inventory consumption quantity on the first day.

[0073] In some optional implementation manners of this embodiment, step 204 may include: if the obtained replenishment quantity is less than or equal to the inventory consumption quantity on the first day, determine the obtained replenishment quantity as the replenishment quantity of the target item and output the obtained replenishment quantity.

[0074] In these optional implementation manners, if the comparison result is that the replenishment quantity obtained after making up a whole box of the initial replenishment quantity is less than or equal to the inventory consumption quantity on the first day, the above-mentioned execution entity can determine the replenishment quantity obtained after making up a whole box of the initial replenishment quantity as the replenishment quantity of the target item and output this replenishment quantity.

[0075] These implementation manners can, in the case where the replenishment quantity obtained after making up a whole box can be consumed relatively quickly, use the replenishment quantity obtained by making up a whole box as the final replenishment quantity of the target item and output it. In this way, it is possible to avoid the problem of excessive inventory items caused by too large a replenishment quantity after making up a whole box.

[0076] In some alternative implementation manners of this embodiment, before step 203, the above method may further include: judging whether the initial replenishment quantity is greater than one case based on the full case quantity; and step 203 may include: if the initial replenishment quantity is greater than one case, comparing, based on the full case quantity, the replenishment quantity obtained after making up a full case from the initial replenishment quantity with the inventory consumption quantity on the first day.

[0077] In these alternative implementation manners, the above execution subject may judge whether the initial replenishment quantity is greater than one case based on the full case quantity, and execute step 203 when the initial replenishment quantity is greater than one case.

[0078] If the initial replenishment quantity is greater than one case, there is a relatively large space for adjusting the initial replenishment quantity. These implementation manners may first judge whether the initial replenishment quantity is greater than one case, and perform subsequent steps when it is greater than one case, so as to avoid performing invalid operations subsequently.

[0079] In some alternative application scenarios of these alternative implementation manners, step 203 may include: if the initial replenishment quantity is not greater than one case, comparing the full case quantity with the inventory consumption quantity on the first day; step 204 may include: if the full case quantity is less than or equal to the inventory consumption quantity on the first day, determining the full case quantity as the replenishment quantity of the target item and outputting it; if the full case quantity is greater than the inventory consumption quantity on the first day, determining the initial replenishment quantity as the replenishment quantity of the target item and outputting it.

[0080] In these alternative application scenarios, if the initial replenishment quantity is less than one case, the above execution subject may compare the magnitudes of the above full case quantity and the inventory consumption quantity on the first day. If the full case quantity is larger, the above execution subject may directly use the initial replenishment quantity as the final replenishment quantity of the target item. If the full case quantity is smaller, the above execution subject may determine the full case quantity as the replenishment quantity of the target item and output it.

[0081] These application scenarios may make up a full case of the target item and use the full case quantity as the final replenishment quantity when the initial replenishment quantity is less than one case and the full case quantity is small, so as to avoid the replenishment quantity obtained after making up a full case being too large.

[0082] It should be noted that the step of making up (to) a full case in this application may be performed when it is determined that the supply of the target item is sufficient.

[0083] Continue to refer to Figure 3 , Figure 3 which is a schematic diagram of an application scenario of the replenishment quantity determination method according to this embodiment. In Figure 3In the application scenario, the execution entity 301 can determine the initial replenishment quantity 302, 7 pieces, of the computer of model X in response to determining that the current inventory quantity of the computer of model X, which is 20 pieces, is less than the inventory threshold of 25 pieces. Obtain the full-box quantity 303, 4 pieces, of the computer of model X, where the full-box quantity is used to indicate the number of pieces of the target item in a full box. Based on the full-box quantity, compare the replenishment quantity of 8 pieces obtained after making up a full box from the initial replenishment quantity of 7 pieces with the inventory consumption quantity of 9 pieces on the first day. Based on the comparison result 304, determine and output the replenishment quantity 305 of the computer of model X.

[0084] Further referring to Figure 4 , which shows the flow 400 of another embodiment of the replenishment quantity determination method. The flow 400 of the replenishment quantity determination method includes the following steps:

[0085] Step 401, in response to determining that the current inventory quantity of the target item is less than the inventory threshold, determine the initial replenishment quantity of the target item.

[0086] In this embodiment, the execution entity (such as Figure 1 the server or terminal device shown) of the replenishment quantity determination method can determine the initial replenishment quantity of the target item when it is determined that the current inventory quantity of the target item is less than the inventory threshold. Here, the inventory threshold is the safety inventory quantity set for the inventory. If the current inventory quantity is lower than the safety inventory quantity, replenishment is required.

[0087] Step 402, obtain the full-box quantity of the target item, where the full-box quantity is used to indicate the number of pieces of the target item in a full box.

[0088] In this embodiment, the above-mentioned execution entity can obtain the full-box quantity of the target item. Here, the full-box quantity, that is, the box specification, can indicate the number of pieces of the target item in the box when the box used to hold the target item is full.

[0089] Step 403, based on the full-box quantity, compare the replenishment quantity obtained after making up a full box from the initial replenishment quantity with the inventory consumption quantity on the first day.

[0090] In this embodiment, the above-mentioned execution entity can determine the replenishment quantity obtained after the initial replenishment quantity is made up to a full case, and based on the full case quantity, compare the size between this replenishment quantity and the inventory consumption quantity on the first number of days. Here, the first number of days is the specified number of days. In practice, based on the full case quantity, the above-mentioned execution entity can determine whether the initial replenishment quantity is greater than one case. Specifically, the initial replenishment quantity may be less than one case, so after making it up to a full case, it is one case. In addition, the initial replenishment quantity may also be greater than one case and not fully made up to a full case. For example, the initial replenishment quantity is two and a half cases. Then, in this case, after the initial replenishment quantity is made up to a full case, the part that is not fully made up to a full case becomes a full case. For example, two and a half cases become three cases.

[0091] Step 404, if the obtained replenishment quantity is greater than the inventory consumption quantity on the first number of days, based on the full case quantity, compare the replenishment quantity of the full cases in the initial replenishment quantity with the inventory consumption quantity on the second number of days, where the first number of days is greater than the second number of days.

[0092] In this embodiment, if the obtained replenishment quantity is greater than the inventory consumption quantity on the first number of days, then the above-mentioned execution entity can, based on the full case quantity, compare the size between the replenishment quantity of the full cases in the initial replenishment quantity and the inventory consumption quantity on the second number of days. Here, the second number of days can be the specified number of days. Specifically, the above-mentioned execution entity can, based on the full case quantity, determine the replenishment quantity of the full cases in the initial replenishment quantity, and then compare the size between the replenishment quantity of the full cases and the inventory consumption quantity on the second number of days.

[0093] In practice, the above-mentioned execution entity can use various methods to compare the replenishment quantity of the full cases in the initial replenishment quantity with the inventory consumption quantity on the second number of days. For example, the above-mentioned execution entity can determine whether the replenishment quantity of the full cases in the initial replenishment quantity is greater than or equal to the inventory consumption quantity on the second number of days. In addition, the above-mentioned execution entity can also determine whether the replenishment quantity of the full cases in the initial replenishment quantity is less than the inventory consumption quantity on the second number of days.

[0094] Specifically, the initial replenishment quantity can be expressed as R, the full case quantity can be expressed as PR, that is, (Packing Rule, case rule), then the replenishment quantity of the full cases is the product of the integer part of the result of R / PR and PR. Correspondingly, the replenishment quantity obtained after making it up to a full case is the product of the sum of the integer part of the result of R / PR plus 1 and PR.

[0095] In some alternative implementation manners of this embodiment, the inventory consumption quantity on the first number of days is the sum of the target inventory quantity and the inventory consumption quantity on the first specified number of days, where the target inventory quantity is greater than the inventory quantity threshold; the inventory consumption quantity on the second number of days is the difference between the target inventory quantity and the inventory consumption quantity on the second specified number of days.

[0096] In these alternative implementations, the inventory consumption quantity is the number of items output from the warehouse where the target item is located, and the warehouse here is the warehouse that needs to be replenished. When the first number of days is greater than the second number of days, the inventory consumption quantity on the first day is greater than the inventory consumption quantity on the second day.

[0097] These implementations can accurately determine the first number of days and the second number of days, and thus obtain an accurate replenishment quantity.

[0098] Optionally, among the replenishment quantities for output of the target item i, the number of full boxes (such as n boxes) can be expressed as:

[0099] min(∑(R i mod PR i ))

[0100] where R i and PR i satisfy the following conditions:

[0101] The above-mentioned R i represents the initial replenishment quantity of the target item i, PR i represents the full box quantity of the target item i, mod is to find the remainder, T i represents the maximum target inventory of the target item i, S i represents the maximum inventory threshold of the target item i. represents taking the integer of R i and PR i .

[0102] Specifically, the maximum target inventory T i can be expressed as T i = t i + n up * f, where t i is the target inventory, n up is the first specified number of days, and f is the predicted daily average value (that is, the daily average value of the inventory consumption quantity of the target item within the target future time period). The maximum inventory threshold S i can be expressed as S i = max(s i , t i - n low * f), that is, take the larger one of the results of s i - n low * f and t i - n low * f. Among them, s i is the inventory threshold, t iLet the stock in the target library be the inventory, and \(f\) be the predicted daily average value. All the above "*" represent multiplication.

[0103] Step 405: If the replenishment quantity of full cases in the initial replenishment quantity is greater than or equal to the inventory consumption quantity on the second day, determine the replenishment quantity of full cases in the initial replenishment quantity as the replenishment quantity of the target item, and output the replenishment quantity of full cases in the initial replenishment quantity.

[0104] In this embodiment, if the comparison result in step 404 is that the replenishment quantity of full cases in the initial replenishment quantity is greater than or equal to the inventory consumption quantity on the second day, the above-mentioned execution entity may determine the replenishment quantity of full cases as the replenishment quantity of the target item.

[0105] In this embodiment, when the replenishment quantity of full cases in the initial replenishment quantity is relatively large, the scattered part can be discarded, and the full-case part in the replenishment quantity can be used as the replenishment quantity of the target item. In this way, it can not only ensure that the inventory after replenishment is relatively sufficient but also avoid the problem of excessive replenishment.

[0106] In some alternative implementation manners of this embodiment, after step 404, the method may further include: If the replenishment quantity of full cases in the initial replenishment quantity is less than the inventory consumption quantity on the second day, determine the initial replenishment quantity as the replenishment quantity of the target item, and output the initial replenishment quantity.

[0107] In these alternative implementation manners, if the comparison result in step 404 is that the replenishment quantity of full cases in the initial replenishment quantity is less than the inventory consumption quantity on the second day, the above-mentioned execution entity may directly determine the initial replenishment quantity as the replenishment quantity of the target item and output it.

[0108] Specifically, if the initial replenishment quantity after making up full cases is greater than the inventory consumption quantity on the first day and the replenishment quantity of full cases is less than the inventory consumption quantity on the second day, then the matching degrees of these two full-case replenishment methods with the inventory consumption quantity are relatively low.

[0109] These implementation manners can use the entire initial replenishment quantity as the actual replenishment quantity when the replenishment quantity of full cases in the initial replenishment quantity is very small and the replenishment quantity obtained by making up full cases is very large.
