Then, through the preset replenishment parameter set and the preset stocking days set, each item information to be tested in the test item information set is tested to obtain the inventory spot rate set and the inventory turnover rate set. Through the inventory spot rate set and the inventory turnover rate set, each item information in the pre-acquired item information set can be classified to obtain the first item information set and the second item information set. Afterwards, an inventory index increase table and an inventory index decrease table are generated, which can be used to characterize the two situations of positive growth and negative growth of inventory consumption. Finally, based on the above-mentioned inventory index increase table and inventory index decrease table, the target inventory information is generated. By generating target inventory information, the two situations of inventory consumption can be complemented to stabilize inventory consumption. Thus, the impact of promotional activities on inventory can be avoided. Thus, the generated target inventory information can be made more accurate. Thus, the purpose of improving the accuracy of generated inventory information is achieved. BRIEF DESCRIPTION OF THE DRAWINGS

Among them, each replenishment parameter in the above-mentioned preset replenishment parameter set can be used to characterize the initial inventory service level of the items represented by each item information to be tested in the item information set to be tested. Each preparation days in the above-mentioned preset preparation days set can be used to characterize the number of days that the items represented by each item information to be tested in the item information set to be tested need to be prepared before replenishment, and can also be used to adjust the inventory turnover rate and the inventory spot rate. The item information set to be tested can be some item information used for testing. Each item information to be tested in the item information set to be tested can include the name of the item and the quantity of the item. The above-mentioned test can be to input the above-mentioned item information set to be tested into a preset test model to generate the inventory spot rate set and the inventory turnover rate set.

The deduction order information in the deduction order information sequence can include the deduction item category and the deduction item quantity (for example, it can include SKU (Stock keeping Unit) and the unit quantity), and each deduction order information in the deduction order information sequence can correspond to a date. Then, the first preset condition can be: the earliest deduction order information among the dates included in each deduction order information in the deduction order information sequence. It can also be the deduction order information whose date included in each deduction order information in the deduction order information sequence is within the earliest day. The deduction order information in the above deduction order information sequence can be used to represent the number of items that need to be deducted from the number of items corresponding to the item category included in the deduction order information. The above target deduction order information is the deduction order information used for the current cycle.

[0057] The second test step is to deduct the number of items included in the to-be-tested item information that matches the target deduction order information in the to-be-tested item information set to obtain the deduction item information set. The corresponding relationship can be determined by the item category included in the to-be-tested item information and the item category included in the target deduction order information. Thus, the number of items included in the to-be-tested item information that matches the target deduction order information in the to-be-tested item information set can be deducted to obtain the deduction item information set.

[0058] The third test step is to generate replenishment order information based on the above-mentioned preset replenishment parameter set, the above-mentioned preset stocking days set, the to-be-tested item information set, the target deduction order information and the deduction item information set. Among them, the replenishment order information may include the item replenishment quantity corresponding to the item category included in each to-be-tested item information in the above-mentioned to-be-tested item information set, and the item replenishment quantity corresponding to each item category. The replenishment order information can be generated in the following manner: First, the mean of the item sales volume corresponding to each item category in the to-be-tested item information set within a preset time period (for example, within 60 days from the current moment as the end time point), the variance of the item sales volume, the mean of the item replenishment consumption time, the procurement cycle corresponding to each item category, and the variance of the item replenishment consumption time and the procurement cycle corresponding to each item category. Then, the in-transit inventory information can be determined. The in-transit inventory information may include the number of in-transit items corresponding to each item category. The in-transit inventory information can be used to characterize the item information in transit. Finally, the item replenishment quantity corresponding to each item category included in the replenishment order information can be generated by the following formula:

[0059]

[0060] Wherein, Q represents the replenishment quantity of the item corresponding to the above item category. k represents the replenishment parameter corresponding to the above item category in the above preset replenishment parameter set. μ VLT Represents the average replenishment time of the above-mentioned item categories. NRT represents the procurement cycle corresponding to the above-mentioned item categories. D Represents the variance of the sales volume of the above item categories. D Represents the mean sales volume of the above item categories. VLT+NRT represents the variance of the replenishment time of the above-mentioned item category and the sum of the procurement cycles of each item category. BP represents the number of days for stocking corresponding to the above-mentioned item category in the above-mentioned preset replenishment parameter set. X represents the sum of the number of items corresponding to the above-mentioned item category in the above-mentioned test item information set. Y represents the number of in-transit items corresponding to the above-mentioned item category.

[0061] In the fourth test step, the number of items included in the item information to be tested that matches the replenishment order information in the deducted item information set to be tested is added to obtain an added item information set. The item information to be tested and the replenishment order information that include the same item category can be determined as a matching relationship. Thus, the sum of the number of items corresponding to each item category in the replenishment order information and the number of items included in the corresponding item information to be tested can be determined as the number of items included in the added item information. The added item information set can be used to characterize the added inventory information in the inventory after simulating a replenishment.

[0062] In a fifth test step, in response to determining that the number of items included in each of the information of the items to be tested in the added information set of the items to be tested is greater than zero, the cycle count value is increased by 1, wherein the initial value of the cycle count value is 0. The cycle count may represent the number of days in the test. For example, a cycle count value of 1 may represent the change in the number of items in the inventory on the first day of the above-mentioned preset time period.

[0063] In the second step, in response to determining that the number of deduction order information in the deduction order information sequence after the deduction order information is selected is equal to zero, based on the cycle count value, the above-mentioned preset deduction order information sequence and the added item information set, an inventory spot rate set and an inventory turnover rate set are generated. Among them, the number of deduction order information in the deduction order information sequence after the deduction order information is selected is equal to zero, which can represent that there is no user order information that needs to be simulated and deducted, thereby ending the cycle. First, the number of days in which the number of items corresponding to each item category in each deduction item information set is greater than zero in all the cycle steps of the test process can be determined. Then, the ratio of the number of days to the cycle count value when the cycle ends can be determined as the inventory spot rate of the item category. Thus, the inventory spot rate set can be obtained. The cycle count value when the cycle ends can be the cycle count value when the number of deduction order information in the deduction order information sequence after the deduction order information is selected is equal to zero. Finally, the inventory turnover rate of the item category can be determined as the ratio of the sum of the item quantities included in each deduction order information corresponding to each item category in the above-mentioned preset deduction order information sequence to the total inventory quantity corresponding to the item category, thereby generating an inventory turnover rate set.

[0064] The total inventory quantity corresponding to an item category can be generated in the following manner: the total inventory quantity corresponding to the item category in each item information to be tested in the sequence of item information to be tested and the sum of the number of items corresponding to the item category in the replenishment order information in each cycle are determined as the total inventory quantity corresponding to the item category.

[0065] In some optional implementations of some embodiments, the execution subject tests each item information to be tested in the item information set to be tested according to a preset replenishment parameter set and a preset stocking days set to obtain an inventory spot rate set and an inventory turnover rate set, and may further include the following steps:

[0066] In response to determining that the number of deduction order information in the deduction order information sequence after the deduction order information is selected is greater than zero, the above test step is performed again. Wherein, the number of deduction order information in the deduction order information sequence after the deduction order information is selected is greater than zero, which can indicate that the test is not completed, so the test step is performed again.

[0067] Step 202: Classify each item information in the pre-acquired item information set according to the inventory spot rate set and the inventory turnover rate set to obtain a first item information set and a second item information set.

[0068] In some embodiments, the execution entity may classify the individual item information in the pre-acquired item information set according to the inventory spot rate set and the inventory turnover rate set to obtain a first item information set and a second item information set. The pre-acquired item information set may be information about items currently in inventory. The item information in the pre-acquired item information set may also include item names. The correspondence between the to-be-tested item information with the same item name and the item information in the pre-acquired item information set may be determined. Thus, the item information in the pre-acquired item information set that meets the classification condition may be determined as the first item information, and the item information that does not meet the classification condition may be determined as the second item information. The classification condition may be that the product of the inventory spot rate and the inventory turnover rate corresponding to the item information in the pre-acquired item information set is greater than a preset classification threshold (e.g., 85%).

[0069] Step 203: Generate an inventory index decrease table based on the first item information set.

[0070] In some embodiments, the execution entity may generate an inventory index decrease table based on the first item information set. Each first item information in the first item information set and the corresponding inventory spot rate and inventory turnover rate may be recorded as a table record in the inventory index decrease table. Thus, an inventory index decrease table may be generated. The inventory index decrease table may be used to characterize the decrease in the index in the pre-acquired item information set. In practice, the index decrease table may be used to record item information whose inventory spot rate and inventory turnover rate do not meet the second preset condition. Therefore, the replenishment parameters may be adjusted lower for each item information in the inventory index decrease table so that the item information in the inventory index decrease table also meets the second preset condition. Thus, the replenishment parameters may be changed according to the actual item consumption to improve the accuracy of the generated inventory information.

[0071] Step 204: Generate an inventory index increase table based on the second item information set.

[0072] In some embodiments, the execution entity may generate an inventory index increase table based on the second item information set. Each second item information in the second item information set and the corresponding inventory spot rate and inventory turnover rate may be recorded as a table record in the inventory index increase table. Thus, an inventory index increase table may be generated. The inventory index increase table may be used to characterize the item information with increased indicators in the pre-acquired item information set. Therefore, the number of days for stocking may be increased for each item information in the inventory index decrease table, so that the item information in the inventory index increase table also meets the second preset condition. Thus, the number of days for stocking may be changed according to the actual item consumption to improve the accuracy of the generated inventory information.

[0073] Step 205: Generate target inventory information based on the inventory index increase table and the inventory index decrease table.

[0074] In some embodiments, the execution subject may generate target inventory information based on the inventory index increase table and the inventory index decrease table. First, the replenishment parameters corresponding to each item information in the inventory decrease table may be adjusted so that the inventory turnover rate and inventory spot rate corresponding to the item category included in the item information meet the second preset condition. Then, the item information in the inventory index increase table and the inventory index decrease table may be merged as the target inventory information.

[0075] Optionally, the execution entity may also replenish the items in stock based on the target inventory information. Figure 3 As shown. The target inventory information 301 may include the inventory availability rate 3011 and the inventory turnover rate 3012 corresponding to each item information. The item replenishment parameter 302 or the item stocking days 303 corresponding to the inventory availability rate 3011 and the inventory turnover rate 3012 included in the above target inventory information may be input into the above formula to generate the item replenishment quantity 304 for replenishment.

[0076] The above-mentioned embodiments of the present disclosure have the following beneficial effects: through the inventory information generation method of some embodiments of the present disclosure, the accuracy of generating inventory information can be improved. Specifically, the reason for the inaccuracy of the generated inventory information is that the influence of special circumstances (for example, promotional activities) on the inventory volume is not considered, and the replenishment parameters in the inventory model are artificially specified and cannot be changed according to the changes in the actual item consumption. Based on this, the inventory information generation method of some embodiments of the present disclosure, first, considering the situation that there is a large impact of promotional activities on the inventory volume in practice, introduces a preset stocking days. Then, through the preset replenishment parameter set and the preset stocking days set, each item information to be tested in the test item information set is tested to obtain the inventory spot rate set and the inventory turnover rate set. Through the inventory spot rate set and the inventory turnover rate set, each item information in the pre-acquired item information set can be classified to obtain the first item information set and the second item information set. Afterwards, an inventory index increase table and an inventory index decrease table are generated, which can be used to characterize the two situations of positive growth and negative growth of inventory consumption. Finally, based on the above-mentioned inventory index increase table and inventory index decrease table, the target inventory information is generated. By generating target inventory information, the two situations of inventory consumption can be complemented to stabilize inventory consumption. Thus, the impact of promotional activities on inventory can be avoided. Thus, the generated target inventory information can be made more accurate. Thus, the purpose of improving the accuracy of generated inventory information is achieved.

[0077] Further references Figure 4, which shows a process 400 of another embodiment of the inventory information generation method. The process 400 of the inventory information generation method includes the following steps:

[0078] Step 401 : testing each item to be tested in the item to be tested information set according to preset replenishment parameters and preset stocking days, and obtaining an inventory spot rate set and an inventory turnover rate set.

[0079] In some embodiments, the specific implementation of step 401 and the technical effects brought about can be referred to Figure 2 The corresponding step 201 in the embodiments will not be described in detail here.

[0080] Step 402: determine the item information that meets the second preset condition in the pre-acquired item information set as the first item information to obtain the first item information set.

[0081] In some embodiments, the execution body of the inventory information generation method (such as Figure 1 The computing device 101 shown in the figure can determine the item information in the above-mentioned pre-acquired item information set that meets the second preset condition as the first item information, and obtain the first item information set. The item information in the above-mentioned pre-acquired item information set may include item categories. The inventory spot rate and inventory turnover rate corresponding to the item category included in the first item information in the above-mentioned first item information set meet the above-mentioned second preset condition. The second preset condition may be that the inventory spot rate and inventory turnover rate corresponding to the item information are both greater than the preset indicator threshold (for example, 95%).

[0082] Step 403: determine the item information in the pre-acquired item information set that does not meet the second preset condition as the second item information, and obtain the second item information set.

[0083] In some embodiments, the execution subject may determine the item information in the pre-acquired item information set that does not meet the second preset condition as the second item information to obtain the second item information set. The second item information in the second item information set that does not meet the second preset condition may be that the inventory spot rate and inventory turnover rate corresponding to the item category included in the second item information do not meet the second preset condition. The item information whose item spot rate and item turnover rate corresponding to the item category are both less than the preset indicator threshold value may be determined as the stacked item information.

[0084] Step 404: Generate an inventory index decline table based on the first item information set.

[0085] In some embodiments, the execution entity may generate an inventory index drop table based on the first item information set. The inventory index drop table may be generated by the following steps:

[0086] The first step is to determine the pre-arrival ending inventory information set corresponding to each first item information in the above-mentioned first item information set. The pre-arrival ending inventory information in the above-mentioned pre-arrival ending inventory information set includes the pre-arrival ending inventory quantity. The above-mentioned pre-arrival ending inventory information set can be used to characterize the ending inventory of items of an item category one day before different arrival dates. Each arrival date can be determined using a preset arrival cycle. Then, the ending inventory of each arrival date within the historical time (for example, within the past 60 days with the current time point as the end time point) can be determined as the pre-arrival ending inventory information.

[0087] In the second step, for each first item information in the first item information set, perform the following steps:

[0088] In the first sub-step, in response to determining that the number of days for stocking corresponding to the first item information is greater than or equal to zero, and the number of stocks before arrival included in the stocking information before arrival in the stocking information set before arrival corresponding to the first item information is greater than 1, the stocking before arrival is adjusted down to the target stocking before arrival. The number of days for stocking is greater than or equal to zero, which indicates that the item needs to be stocked for at least one day. Therefore, such an item needs to be stocked in advance to avoid the situation where the item is sold out. The target stocking before arrival can be 1. The stocking before arrival can be used to characterize the remaining amount of the items in the inventory before replenishment. At this time, the fewer the number of items included in the stocking before arrival, the more the inventory of the item meets the market demand, that is, the items in the inventory meet the needs of users. Secondly, when the stocking before arrival is greater than 1, the stocking before arrival can be adjusted to 1. The stocking before arrival adjusted to 1 can be used for the replenishment parameter of reverse adjustment.

[0089] The second sub-step is to generate a lowered replenishment parameter based on the above target end-of-period inventory quantity. The above target end-of-period inventory quantity 1 can be used as a target for lowering the replenishment parameter, so as to lower the replenishment parameter. After the item replenishment quantity is generated by the above formula, the end-of-period inventory quantity before the arrival of the goods is equal to the above target end-of-period inventory quantity. Thus, the lowered replenishment parameter is generated.

[0090] In the third step, for each first item information in the first item information set, the adjusted replenishment parameter corresponding to the first item information that satisfies the third preset condition is determined as the first target replenishment parameter to obtain the first target replenishment parameter set. The third preset condition may be: the adjusted replenishment parameter has the smallest change compared to the preset replenishment days. In addition, each first item information may correspond to one first target replenishment parameter.

[0091] In the fourth step, each first target replenishment parameter in the above-mentioned first target replenishment parameter set is used to update the preset initial inventory curve to generate a first inventory curve, and obtain a first inventory curve set. The initial inventory curve can be a preset inventory curve, which is used to characterize the change in the end-of-period inventory within a period of time before the update (for example, within two months from the current time as the starting time point). The independent variable of the initial inventory curve can be each arrival date within the above-mentioned period of time, that is, the arrival date. The dependent variable can be the end-of-period inventory amount one day before each arrival date. The first target replenishment parameter can be used to adjust the replenishment amount of the corresponding first item information.

[0092] In some embodiments, first, the first target replenishment parameter can be substituted into the above formula to generate the replenishment quantity corresponding to the first item information. Then, the sum of the ending inventory quantity before the arrival date included in the first item information and the replenishment quantity can be determined as the inventory quantity after replenishment. Then, the inventory quantity after replenishment is deducted by the deduction item quantity included in the preset deduction order information, and the ending inventory quantity one day before the arrival date can be obtained. Finally, the parameters of the initial inventory curve can be adjusted using the independent variables in the above initial inventory curve so that the corresponding arrival date is the ending inventory quantity, thereby completing the update of the above initial inventory curve. Thus, the entire initial inventory curve can be updated to obtain the first inventory curve. Thus, the preset initial inventory curve can be updated using each first target replenishment parameter to obtain a first inventory curve set. In addition, each first target replenishment parameter can correspond to a first inventory curve.

[0093] Step 5: Using each first inventory curve in the first inventory curve set, the preset initial stock-out cycle and initial stock-out date are adjusted to generate the first stock-out cycle and the first stock-out date, and obtain the first stock-out cycle set and the first stock-out date set. The initial stock-out cycle can be used to characterize the time interval between the stock-out dates when the end-of-period inventory is less than zero within the predicted period before the inventory curve is updated. The initial stock-out date can be used to characterize all time points when the end-of-period inventory is less than zero within the predicted period before the inventory curve is updated.

[0094] In some embodiments, first, the above-mentioned dates in the first inventory curve where the end-of-period inventory is less than zero can be counted as the first out-of-stock date. Then, the time intervals between the various time points in the out-of-stock date can be determined as the first out-of-stock cycle. Thus, the initial out-of-stock cycle and the initial out-of-stock date can be adjusted to the first out-of-stock cycle and the first out-of-stock date. Thus, the preset initial out-of-stock cycle and the initial out-of-stock date can be adjusted using each first inventory curve in the above-mentioned first inventory curve set to obtain a first out-of-stock cycle set and a first out-of-stock date set. In addition, each first inventory curve can correspond to a first out-of-stock cycle and a first out-of-stock date.

[0095] In some optional implementations of some embodiments, the execution subject generates the inventory index decline table based on the first item information set, and may further include the following steps:

[0096] In the first step, for each first item information in the first item information set, perform the following steps:

[0097] In the first sub-step, in response to determining that the number of days for preparation corresponding to the first item information is less than zero, and the number of inventory before arrival included in the end-of-arrival inventory information set corresponding to the first item information is greater than 1, the end-of-arrival inventory quantity before arrival is adjusted down to the target end-of-period inventory quantity. The number of days for preparation being less than zero can indicate that the corresponding item can be replenished at the time when replenishment is needed. Therefore, there is no need to have a large amount of inventory before arrival remaining. Therefore, the end-of-period inventory quantity before arrival can be adjusted down to the target end-of-period inventory quantity.

[0098] The second sub-step is to generate a lowered stocking days based on the target end-of-period inventory quantity. The preset stocking days corresponding to the first item information may be lowered so that the item replenishment quantity is generated using the lowered stocking days, and after replenishing the inventory items, the end-of-period inventory quantity before the arrival of the goods is exactly equal to the target end-of-period inventory quantity.

[0099] In the second step, the lowered stocking days corresponding to each first item information in the first item information set that meets the fourth preset condition are determined as the first target stocking days, and the first target stocking days set is obtained. The fourth preset condition may be that the change in the lowered stocking days compared to the preset stocking days is the smallest. In addition, each first item information may correspond to a first target stocking days.

[0100] The third step is to update the preset initial inventory curve using each first target stocking days in the first target stocking days set to generate a second inventory curve and obtain a second inventory curve set. First, the first target stocking days can be substituted into the above formula to generate the replenishment quantity corresponding to the second item information. Then, the sum of the end-of-stock inventory quantity before the shortage period included in the second item information and the replenishment quantity can be determined as the inventory after replenishment. Then, the inventory after replenishment is deducted by the deduction item quantity included in the preset deduction order information to obtain the end-of-period inventory one day before the arrival date. Finally, the parameters of the initial inventory curve can be adjusted using the independent variables in the initial inventory curve so that the corresponding arrival date is the end-of-period inventory, thereby completing the update of the initial inventory curve. Thus, the entire initial inventory curve can be updated to obtain the second inventory curve. Thus, the preset initial inventory curve can be updated using each first target stocking days to obtain the second inventory curve set. In addition, each first target stocking day can correspond to a second inventory curve.

[0101] In the fourth step, each second inventory curve in the second inventory curve set is used to adjust the preset initial out-of-stock cycle and the initial out-of-stock date to generate a second out-of-stock cycle and a second out-of-stock date, and obtain a second out-of-stock cycle set and a second out-of-stock date set. First, the dates in the second inventory curve where the end-of-period inventory is less than zero can be counted as the second out-of-stock date. Then, the time interval between each time point in the out-of-stock date can be determined as the second out-of-stock cycle. Thus, the initial out-of-stock cycle and the initial out-of-stock date can be adjusted to the second out-of-stock cycle and the second out-of-stock date. Thus, each second inventory curve in the second inventory curve set can be used to adjust the preset initial out-of-stock cycle and the initial out-of-stock date to obtain a second out-of-stock cycle set and a second out-of-stock date set. In addition, each second inventory curve can correspond to a second out-of-stock cycle and a second out-of-stock date.

[0102] In some optional implementations of some embodiments, the execution subject generates the inventory index decline table based on the first item information set, and may further include the following steps:

[0103] Based on the above-mentioned first out-of-stock cycle set, the above-mentioned first out-of-stock date set, the above-mentioned second out-of-stock cycle set, the above-mentioned second out-of-stock date set and the above-mentioned first item information set, an inventory index decline table is generated. Among them, firstly, the inventory change corresponding to the first out-of-stock cycle and the first out-of-stock date or the first target replenishment parameter or the first target stocking days corresponding to the second out-of-stock cycle and the second out-of-stock date corresponding to each of the above-mentioned first item information can be determined as a record in the inventory index decline table. Then, each table record can be sorted in the order of the inventory change from small to large to obtain the inventory index decline table.

[0104] Step 405: Generate an inventory index increase table based on the second item information set.

[0105] In some embodiments, the execution entity may generate an inventory index increase table based on the second item information set. The inventory index increase table may be generated by the following steps:

[0106] The first step is to determine the pre-out-of-stock ending inventory information set corresponding to each second item information in the above second item information set. The pre-out-of-stock ending inventory information in the above pre-out-of-stock ending inventory information set may include the pre-out-of-stock ending inventory quantity and the out-of-stock quantity. The pre-out-of-stock ending inventory information set of the items corresponding to the item categories included in the above-mentioned second item information on each arrival date may be obtained. The pre-out-of-stock ending inventory information may be used to characterize the information of the items one day before replenishment. The pre-out-of-stock ending inventory quantity included in the pre-out-of-stock ending inventory information may be the number of items remaining in the inventory one day before replenishment. The out-of-stock quantity may be the number of items still missing before replenishment in addition to the remaining number of items.

[0107] Step 2: For each second item information in the second item information set, perform the following steps:

[0108] In a first sub-step, in response to determining that the replenishment parameter corresponding to the second item information is less than or equal to a preset replenishment parameter threshold, and the sum of the pre-outage ending inventory quantity and the stock-out quantity included in the pre-outage ending inventory information set corresponding to the second item information is less than 1, the end-of-period inventory quantity is adjusted up to a target end-of-period inventory quantity, wherein the sum of the target end-of-period inventory quantity and the stock-out quantity is 1.

[0109] As an example, the preset replenishment parameter threshold may be: 0.995.

[0110] The second sub-step is to generate an increased replenishment parameter based on the target end-of-period inventory quantity. The preset replenishment parameter corresponding to the first item information may be increased so that the item replenishment quantity generated by the increased replenishment parameter is equal to the sum of the end-of-period inventory quantity and the stock-out quantity obtained after replenishing the inventory items.

[0111] In the third step, the adjusted replenishment parameters corresponding to each second item information in the second item information set that meet the fifth preset condition are determined as the second target replenishment parameters to obtain the second target replenishment parameter set. The fifth preset condition may be: the adjusted replenishment parameters have the smallest change compared to the preset replenishment parameters. In addition, each second item information may correspond to one second target replenishment parameter.

[0112] In the fourth step, each second target replenishment parameter in the second target replenishment parameter set is used to update the preset initial inventory curve to generate a third inventory curve and obtain a third inventory curve set. First, the second target replenishment parameter can be substituted into the above formula to generate the replenishment quantity corresponding to the second item. Then, the sum of the ending inventory quantity before the shortage period included in the second item information and the replenishment quantity can be determined as the inventory after replenishment. Then, the inventory after replenishment is deducted by the deduction item quantity included in the preset deduction order information, and the ending inventory one day before the arrival date can be obtained. Finally, the independent variable in the initial inventory curve corresponding to the arrival date can be adjusted to the ending inventory, so as to complete the update of the initial inventory curve. In this way, the entire initial inventory curve can be updated to obtain the third inventory curve. Thus, the preset initial inventory curve can be updated by using each second target replenishment parameter to obtain the third inventory curve set. In addition, each second target replenishment parameter can correspond to a third inventory curve.

[0113] In the fifth step, each third inventory curve in the third inventory curve set is used to adjust the preset initial stock-out cycle and the initial stock-out date to generate a third stock-out cycle and a third stock-out date, and obtain a third stock-out cycle set and a third stock-out date set. Among them, first, the date in the third inventory curve where the end-of-period inventory is less than zero can be used as the third stock-out date. Then, the time interval between each time point in the stock-out date can be determined as the third stock-out cycle. Thus, the initial stock-out cycle and the initial stock-out date can be adjusted to the third stock-out cycle and the third stock-out date. Thus, each third inventory curve in the third inventory curve set can be used to adjust the preset initial stock-out cycle and the initial stock-out date to obtain a third stock-out cycle set and a third stock-out date set. In addition, each third inventory curve can correspond to a third stock-out cycle and a third stock-out date.

[0114] In some optional implementations of some embodiments, the execution subject generates the inventory index increase table based on the second item information set, and may further include the following steps:

[0115] In the first step, for each second item information in the second item information set, perform the following steps:

[0116] In a first sub-step, in response to determining that the replenishment parameter corresponding to the second item information is greater than the preset replenishment parameter threshold, and the sum of the pre-outage ending inventory quantity and the stock-out quantity included in the pre-outage ending inventory information set corresponding to the second item information is less than 1, the end-of-period inventory quantity is adjusted up to the target end-of-period inventory quantity, wherein the sum of the target end-of-period inventory quantity and the stock-out quantity is 1.

[0117] The second sub-step is to generate an increased number of lead time days based on the target end-of-period inventory quantity. The preset lead time days corresponding to the first item information may be increased so that the item replenishment quantity generated by the increased lead time days is equal to 1, and the sum of the end-of-period inventory quantity and the stock-out quantity obtained after replenishing the inventory items is 1. In this way, the increased number of lead time days may be generated.

[0118] In the second step, the increased stocking days corresponding to each second item information in the second item information set that meets the sixth preset condition is determined as the second target stocking days, and a second target stocking days set is obtained. The sixth preset condition may be: the increased stocking days have the smallest change compared to the preset stocking days. In addition, each second item information may correspond to a second target stocking days.

[0119] In the third step, the preset initial inventory curve is updated by using each second target stocking days in the second target stocking days set to generate a fourth inventory curve, and a fourth inventory curve set is obtained. First, the second target stocking days can be substituted into the above formula to generate the replenishment quantity corresponding to the second item. Then, the sum of the end-of-stock quantity before the shortage period included in the second item information and the replenishment quantity can be determined as the inventory after replenishment. Then, the inventory after replenishment is deducted by the deduction item quantity included in the preset deduction order information, and the end-of-period inventory on the day before the arrival date can be obtained. Finally, the independent variable in the initial inventory curve can be adjusted to the end-of-period inventory corresponding to the arrival date, so as to complete the update of the initial inventory curve. Thus, the entire initial inventory curve can be updated to obtain the fourth inventory curve. Thus, the preset initial inventory curve can be updated by using each second target stocking days to obtain the fourth inventory curve set. In addition, each second target stocking days can correspond to a fourth inventory curve.

[0120] In the fourth step, each fourth inventory curve in the fourth inventory curve set is used to adjust the preset initial out-of-stock cycle and the initial out-of-stock date to generate a fourth out-of-stock cycle and a fourth out-of-stock date, and obtain a fourth out-of-stock cycle set and a fourth out-of-stock date set. First, the date in the fourth inventory curve where the end-of-period inventory is less than zero can be determined as the fourth out-of-stock date. Then, the time interval between each time point in the out-of-stock date can be determined as the fourth out-of-stock cycle. Thus, the initial out-of-stock cycle and the initial out-of-stock date can be adjusted to the fourth out-of-stock cycle and the fourth out-of-stock date. Thus, each fourth inventory curve in the fourth inventory curve set can be used to adjust the preset initial out-of-stock cycle and the initial out-of-stock date to obtain a fourth out-of-stock cycle set and a fourth out-of-stock date set. In addition, each fourth inventory curve can correspond to a fourth out-of-stock cycle and a fourth out-of-stock date.

[0121] In some optional implementations of some embodiments, the execution subject generates the inventory index increase table based on the second item information set, and may further include the following steps:

[0122] Based on the third out-of-stock cycle set, the third out-of-stock date set, the fourth out-of-stock cycle set, the fourth out-of-stock date set and the second item information set, an inventory index increase table is generated. First, the third out-of-stock cycle and the third out-of-stock date corresponding to each second item information, or the second target replenishment parameter corresponding to the fourth out-of-stock cycle and the fourth out-of-stock date, or the second target stocking days corresponding to the inventory change can be determined as a record in the inventory index increase table. Then, each table record can be sorted in the order of inventory change from small to large to obtain an inventory index increase table.

[0123] Step 406: Based on a preset replacement condition, corresponding table records between the inventory index decrease table and the inventory index increase table are replaced with each other to generate target inventory information.

[0124] In some embodiments, the execution subject may replace the corresponding table records between the inventory index decrease table and the inventory index increase table based on a preset replacement condition to generate target inventory information. The preset replacement condition may be: the table record in the inventory index increase table is the same as the absolute value of the time change represented by the table record in the inventory index decrease table. And the table record in the inventory index decrease table includes an absolute value of the inventory change that is greater than the inventory change corresponding to the table record in the inventory index increase table. Thus, the average of the replenishment parameters or preparation days corresponding to the table records between the inventory index decrease table and the inventory index increase table that meet the replacement conditions can be taken as the final replenishment parameters or preparation days. Thus, the replenishment parameters and preparation days corresponding to each item information in the item information set can be obtained as the target inventory information.

[0125] In some embodiments, the specific implementation of step 406 and the technical effects brought about can be referred to Figure 2 The corresponding step 205 in the embodiments will not be described in detail here.

[0126] from Figure 4 It can be seen that Figure 2 Compared with the description of some corresponding embodiments, Figure 4The process 400 of the inventory information generation method in some corresponding embodiments reflects the process of adjusting the replenishment parameters in the preset replenishment parameter set and the stocking days in the preset stocking days set, and generating the inventory index increase table and the inventory index decrease table. Among them, the situation that the number of items in the inventory is more than the market demand is first considered. At this time, the replenishment parameter or the stocking days can be reduced to reduce the item replenishment quantity. Thus, the number of items in the inventory is reduced. So that the optimal inventory spot rate and inventory turnover rate can be obtained. Thus, the accuracy of inventory information is improved. In the process of generating the inventory index increase table, whether the replenishment parameter is greater than the preset replenishment parameter threshold is first considered. When the replenishment parameter is less than or equal to the preset replenishment parameter threshold, the method of increasing the replenishment parameter can be used to make the sum of the inventory quantity at the end of the pre-outage period and the out-of-stock quantity equal to the target end-of-period inventory quantity. When the replenishment parameter is greater than the preset replenishment parameter, the method of increasing the stocking days can be used to make the sum of the inventory quantity at the end of the pre-outage period and the out-of-stock quantity equal to the target end-of-period inventory quantity. Then, whether the stocking days are less than zero is considered. When the number of lead days is less than zero, the method of lowering the replenishment parameters can be used to make the end-of-period inventory quantity reach the target end-of-period inventory quantity. When the number of lead days is greater than zero, the method of lowering the number of lead days can be used to make the end-of-period inventory quantity reach the target end-of-period inventory quantity. Thus, the replenishment parameters and lead days can be flexibly adjusted according to the actual item consumption, so that the control of the item replenishment quantity can be more accurate. Afterwards, the generated inventory index increase table and inventory index decrease table can respectively represent the item information of the increased index (for example, the replenishment parameters and the number of lead days) and the item information of the decreased index. Finally, according to the above-mentioned preset replacement conditions, the item information included in the inventory index increase table and the inventory index decrease table is verified to improve the accuracy of the generated target inventory information.
