Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Article transferring method
As shown in fig. 1, the method for transferring an article according to the embodiment of the present invention includes: an information acquisition step S101, a data calculation step 102, a threshold setting step 103, and an article allocation step 104.
An information acquisition step 101 of acquiring inventory information, ex-warehouse information, and item allocation information of a target item.
As shown in fig. 2, in an information acquisition step 101, information of a target item in a database is acquired. The information of the target object comprises inventory information, ex-warehouse information and object allocation information.
The inventory information includes the daily orderable inventory of the target item at each bin. The ex-warehouse information comprises daily ex-warehouse quantity of the target item and attribute information of the target item. The attribute information of the target item includes whether the target item is a new item (i.e., an item newly added based on the original item type), a department to which the target item belongs, a category to which the target item belongs, whether the target item is put in a cabinet, and the like.
The commodity allocation information includes an allocation target bin (commodity allocation bin, i.e., bin requiring replenishment), commodity allocation time, estimated arrival time, actual arrival time, commodity allocation amount, arrival quantity, supplier, purchaser, actual safe stock days (VLT (Vendor lead time)), and the like of the target commodity. The item allocation information may further include parameters in the item allocation model, such as the number of days in safety stock (VLT)model) Model safety stock (safety stock)model) Model target inventory (target inventory)model) Article allocation period (VLT)model+NRTmodel(NRT is Next reorder time, i.e., the time interval from the Next order today)). The item allocation information may further include a predicted daily stock-out amount (predicted stock-out amount) of the target item, a predicted safe stock amount, and a predicted target stock amount.
Specifically, the number of days of safety stock refers to a time interval (in days) from the start of placing an order for an item (item placement time) to the expected arrival time; the real safe stock days refer to the time interval (in days) from the placing of an order from the article transfer to the real arrival time, the article transfer cycle refers to the time interval (in days) between two successive article transfers, and the target stock days refer to the time interval (in days) between the real arrival time from the placing of an order from the first article transfer to the second article transfer in two successive article transfer behaviors.
And a data calculation step S102, calculating the stock data and the ex-warehouse data of the target object according to the stock information, the ex-warehouse information and the object allocation information.
In the data calculation step S102, the following stock data is calculated from the information of the target item:
orderable stock before allocating goods (orderable stock)beforeI.e., daily inventory of target items, all available for daily ordering)' (ii),
Orderable stock (orderable stock) after article transferafter)、
Orderable inventorybeforeNumber of days to leave warehouse (pre _ day), and
orderable inventoryafterDay of warehouse-out (post _ day).
Wherein the orderable inventorybeforeThe target article stock is the stock of the target article when the article is placed and orderedafterMeans orderable inventorybeforeAnd the sum of the item allocation quantity of the target item. And then calculating to obtain pre _ day and post _ day according to the warehouse-out information of the target object.
According to the inventory information and the ex-warehouse information of the target object, respectively calculating the following ex-warehouse data:
days of safety stock (VLT)model) Sum of ex-warehouse quantities of inner target articles (sales)VLT_model) And standard deviation of ex warehouse quantity (std)VLT_model)；
Article pick-up period (VLT)model+NRTmodel) Sum of ex-warehouse quantities of inner target articles (sales)VLT_model+NRT_model) And standard deviation of ex warehouse quantity (std)VLT_model+NRT_model)；
Sum of ex-warehouse quantities (sales) of target items within real safety inventory days (VLT)VLT)；
Target days in inventory (VLT)Z_cr+ NRT) (let TD ═ VLTZ_crSum of delivery amounts of target articles (sales) in + NRTTD) And standard deviation of ex warehouse quantity (std)TD)；
Target days in inventory (VLT)Z_cr+ NRT, where VLTZ_crZ, which refers to the empirical distribution of VLT for the target item over the last 3 monthscrQuantile, cr being the desired item satisfaction rate); and
maximum value of VLT empirical distribution for target article for approximately 3 months (VLT)max)。
In the above calculation process, the calculation method of the standard deviation of the shipment quantity is not particularly limited, but in the embodiment of the present invention, the standard deviation of the shipment quantity is calculated in the following manner: firstly, calculating the average value and the actual standard deviation of the ex-warehouse quantity in the statistical period, assuming that the ex-warehouse quantity in each day in the statistical period is in normal distribution, regarding the ex-warehouse quantity which is larger than the average value and the standard deviation of the ex-warehouse quantity plus 3 delta of the ex-warehouse quantity as abnormal ex-warehouse quantity according to the principle of normal distribution 3 delta, and after eliminating the abnormal ex-warehouse quantity, calculating the standard deviation again to be the final ex-warehouse quantity standard deviation.
A threshold setting step S103 of setting a threshold based on the shipment data.
In the threshold value setting step S103, threshold value sections of the safe stock quantity, the target stock quantity, pre _ day, and post _ day are set, respectively.
Specifically, the threshold value interval of the threshold value is set so that the daily delivery amount of the target item is normal. That is, assuming that the daily delivery amount of the target item is normally distributed, the threshold interval is set as follows:
setting the lower limit of the threshold interval of the safe stock quantity as salesVLTAnd the upper limit of the safe stock quantity threshold value interval is set as max (sales)VLT_model+stdVLT_model*Zcr，salesVLT+stdVLT*Zcr)；
Setting the lower limit of the threshold interval of the target stock quantity as salesTDAnd the upper limit of the threshold interval of the target stock quantity is set to salesTD+stdTD*Zcr；
The lower limit of pre _ day threshold interval is set to VLT, and the upper limit of pre _ day threshold interval is set to VLTZ_cr(ii) a And is
The lower limit of the post _ day threshold interval is set to VLTZ_cr+ NRT, with the upper limit of the post _ day threshold interval set to VLTmax+NRT。
And an item allocation step S104, determining an evaluation result of item information according to the threshold and the inventory data in a mode that the daily delivery volume of the target item in the delivery information is subjected to normal distribution, and performing item allocation according to the evaluation result.
In the item transfer step S104, the following comparisons are made:
comparing orderable inventorybeforeWhether the current time is within the threshold interval of the safe stock;
comparing orderable inventoryafterWhether the current time is within a target inventory threshold interval;
comparing whether pre _ day is within a pre _ day threshold interval; and
it is compared whether post _ day is within the post _ day threshold interval.
And then, according to the comparison result, whether the article information is reasonable or not is evaluated, and then the article is allocated according to the evaluation result (including reasonable and unreasonable). Specifically, the rationality of the item information is evaluated mainly from two aspects, namely an item allocation period and an item allocation amount.
When any one of the following conditions is met, the article allocation time is judged to be too late, namely 'late adjustment', and the article allocation period can be shortened according to the evaluation result:
(1) orderable inventorybeforeLess than a lower limit of a threshold interval of a safe inventory, an
(2) pre _ day is less than the lower limit of the pre _ day threshold interval; and is
When the following conditions are met, the article allocation time is judged to be too early, namely 'early adjustment', and the article allocation period can be prolonged according to the evaluation result:
(3) orderable inventorybeforeGreater than the upper limit of the safe inventory threshold interval and pre _ day greater than the upper limit of the pre _ day threshold interval.
When any one of the following conditions is met, the article allocation amount is judged to be too small, namely, the article allocation amount is judged to be too small, and the article allocation amount can be increased directly according to the evaluation result:
(1) orderable inventoryafterA lower limit less than a target inventory threshold interval, an
(2) post _ day is less than the lower limit of the post _ day threshold interval;
when the following conditions are met, the article allocation amount is judged to be excessive, namely, the article allocation amount is adjusted to be excessive, and the article allocation amount can be reduced according to the evaluation result:
(3) orderable inventoryafterIs greater than the upper limit of the target stock quantity threshold interval and the post _ day is greater than the upper limit of the post _ day threshold interval.
When the above conditions are not met, the article information is judged to be reasonable, and article allocation is carried out according to an original allocation mode (an original allocation period and an original allocation quantity) without adjusting the article allocation.
As described above, the unreasonable timing of the article allocation mainly includes two cases of "early adjustment" and "late adjustment", and the unreasonable amount of the article allocation mainly includes two cases of "less adjustment" and "more adjustment". When the article information is judged to be unreasonable, the article information can be marked according to the standards in terms of 'early adjustment', 'late adjustment', 'less adjustment' and 'more adjustment'.
In an embodiment of the present invention, the method for transferring an item of the present invention further includes a attribution step S105, a summarizing step S106, and an adjusting step S107.
Attribution step S105
As shown in fig. 2, in the attribution step S104, attribution processing is performed on the article information judged to be not reasonable and marked in the data evaluation step S104, and then the original set allocation manner is adjusted according to the attribution result (corresponding to a subset of the evaluation result)
Attributing the article information judged that the article allocation timing is unreasonable according to the following priority order:
(1) if the article information is marked as "late", and VLTmodelIf the value is smaller than the lower limit of the pre _ day threshold interval, the reason that the unreasonable article allocation time is determined to be VLT in the article allocation modelmodelSetting to be small, namely, smaller than an actual value; if the article information is marked as "early tune", and VLTmodelIf the value is larger than the upper limit of the pre _ day threshold interval, the reason that the unreasonable article allocation time is determined to be VLT in the article allocation modelmodelThe setting is larger, i.e. larger than the actual value;
(2) if the article information is marked as "late", and VLTmodelThe setting is reasonable, and the predicted ex-warehouse quantity is smaller than the real ex-warehouse quantity, the reason that the time for transferring the articles is unreasonable is judged because the predicted ex-warehouse quantity is smaller, namely, smaller than the actual value; if the article information is marked as "early tune", and VLTmodelThe setting is reasonable, and the predicted delivery amount is larger than the real delivery amount, so that the reason that the time for transferring the articles is unreasonable is judged to be larger than the actual value because the predicted delivery amount is larger.
(3) If VLT>VLTz_crAnd pre _ day<VLT, and the article information is judged to be 'late', the reason that the article allocation time is unreasonable is judged to be that the delivery time of the supplier is longer than the actual value.
On the other hand, the article information judged that the article allocation amount is not reasonable is attributed in the following order of priority:
(1) if the area covered by the article allocation bin is changed and the article allocation amount is judged to be unreasonable within a period of time after the article is allocated, judging that the unreasonable article allocation amount is caused by the change of the coverage network structure;
(2) if the attribute of the article is a new article and the article allocation amount is judged to be unreasonable, judging that the reason why the article allocation amount is unreasonable is new article allocation;
(3) if VLTmodel+NRTmodelIs less than the lower limit of the threshold interval of post _ day, and the article information is marked as 'less adjustment', the reason that the article transfer amount is unreasonable is judged to be VLTmodelSetting to be small, namely, smaller than an actual value;
(4) if VLTmodel+NRTmodelIs larger than the upper limit of the post _ day threshold interval, and the article information is marked as 'more than needed', the reason that the unreasonable article transfer amount is determined to be VLTmodelThe setting is larger, i.e. larger than the actual value;
(5) if the target inventory amountmodelIf the predicted quantity of the goods is smaller than the real quantity of the goods, the reason that the goods allocation time is unreasonable is judged to be that the predicted quantity of the goods is smaller, namely smaller than the actual value;
(6) if the target inventory amountmodelAnd if the maximum value of the target stock quantity threshold is exceeded, the article information is marked as the quantity of the articles to be dispatched is increased, and the predicted delivery volume is larger than the real delivery volume, the reason that the timing of dispatching the articles is unreasonable is judged to be that the predicted delivery volume is larger, namely, the predicted delivery volume is larger than the actual value.
Step S106
As shown in fig. 2, in the summarizing step S106, the reasonable percentage of all the item information in a specific time period, and the respective percentages of the unreasonable causes and the unreasonable causes are summarized. For example, X pieces of item information are collectively evaluated in the data evaluation step S104, wherein it is determined that N pieces of item information are unreasonable, and in the attribution step S105, the N pieces of unreasonable item information are attributed, obtaining a total of M causes causing the unreasonable item information. At this time, in the aggregating step 106, the following information is aggregated:
(1) the rational proportion of the item information, i.e., N/X,
(2) m specific reasons for the unreasonable item information,
(3) the number of causes (M1, M2, M3 … …) is proportional to the unreasonable total, i.e., M1/M, M2/M, M3/M … ….
Adjustment step S107
In the download step S107, the aggregated data is sent to the purchasing system. The buyer can refer to the summarized data when transferring the articles to adjust the article transferring mode (such as increasing the number of the articles to be transferred, shortening the transferring time and the like) so as to provide reference for the article information of the buyer and avoid repeated unreasonable behaviors.
