Detailed Description
Currently, many warehouses for storing products are provided with a warehouse management system for managing the articles in the warehouse, for example, the system may record information of the products in the warehouse, specifically, the information may include the number of the products, the names of the products, and the like. The warehouse management system may also determine whether replenishment is required for the product according to the number of the product, for example, when the number of a product is low, a replenishment list corresponding to the product may be generated.
In practical applications, however, as products are updated, there may be alternative relationships between products. For example, the second product is used to replace the first product.
Fig. 1 is a schematic diagram illustrating an alternative relationship between products according to an exemplary embodiment of the present application.
As shown in fig. 1, there may be alternative relationships between multiple products, for example, product a may replace product B, and product B may also replace product a. For example, in a scenario where a manufacturer upgrades a product a to produce a product B and the product a and the product B are randomly shipped when a user purchases the product, the product a and the product B may be replaced with each other.
Continuing with FIG. 1, for another example, product B may replace product C, but product C cannot replace product B.
In such a case where there is a product substitution relationship, a problem arises if products are simply restocked according to the number of individual products. For example, when the product C is replaced by the product B at the time of sale, if the product C is restocked, the product backlog may be caused when the number of the product C is small.
Therefore, how to perform effective inventory management and specifically how to determine the replenishment quantity of each product under the condition that the substitution relationship exists among the products is a technical problem to be solved by the application.
FIG. 2 is a flow chart illustrating a method of determining a product replenishment quantity in accordance with an exemplary embodiment of the present application.
As shown in fig. 2, the method for determining the replenishment quantity of a product provided by this embodiment includes:
step 201, obtaining inventory information of the warehouse and product information of products stored in the warehouse, and determining target products according to the inventory information and the product information.
The method provided by the application can be executed by an electronic device with computing capability. The electronic device may be a separate device, such as a computer, which may act as a server of the warehouse management system. The electronic device may also be a plurality of devices for warehouse management, such as a cluster server.
The method provided by the application can be arranged in a warehouse management system, so that the warehouse management system can reasonably determine the replenishment quantity of the products in the warehouse based on the method provided by the application, and the replenishment quantity is used for replenishing the products in the warehouse.
Specifically, the electronic device may obtain inventory information for the warehouse. For example, the warehouse management system is configured to manage a first warehouse and a second warehouse, and when determining the replenishment quantity of the product in the first warehouse, the electronic device may obtain the inventory information of the first warehouse, and when determining the replenishment quantity of the product in the second warehouse, the electronic device may obtain the inventory information of the second warehouse.
Further, the warehouse information may include a plurality of information such as black and white lists, establishment of storage, warehouse networks, warehouse products, and the like.
In actual application, when the replenishment quantity of the product is determined, the electronic equipment can also acquire the product information of the product stored in the warehouse. For example, the warehouse management system is configured to manage a first warehouse and a second warehouse, and when determining the replenishment quantity of the product in the first warehouse, the electronic device may obtain product information of the product stored in the first warehouse, and when determining the replenishment quantity of the product in the second warehouse, the electronic device may obtain product information of the product in the second warehouse.
The product information of a product may include an alternative chain in which the product is located, for example, other products that the product replaces, and other products that are used to replace the product.
Specifically, products which can be restocked can be screened out first according to product information. For example, if a product is the end piece in the replacement chain, the product is one that can be restocked. The end piece is the last product in the replacement chain, and the end piece is the latest product in the upgrade compared to other products in the replacement chain.
For example, if an alternative relationship between products is indicated by an arrow, a first product replaces a second product, then the two may be connected by an arrow pointing from the first product to the second product. The product with only the arrow tail connected in the substitute chain can be used as the product capable of being restocked. If the substitute chain includes a bidirectional substitute relationship, for example, the first product points to the second product, and the second product also points to the first product, the directional relationship can be split into two cases, so as to obtain two substitute subchains, and then the product which can be restocked is determined according to the arrow direction.
Fig. 3 is a schematic diagram of an alternate chain shown in an exemplary embodiment of the present application.
As shown in fig. 3, product a5 replaces product a4, product a4 replaces product A3, product A3 replaces product a2, and product A3 replaces product a1, then product a5 is the last piece in the replacement chain.
And further determining a target product from the products which can be restocked according to the inventory information. Specifically, target products meeting replenishment conditions can be screened out according to a plurality of information such as black and white lists, building and storing, warehouse networks, warehouse commodities and the like.
Step 202, determining the total inventory amount according to a substitution chain to which the target product belongs, wherein the substitution chain comprises a plurality of products and substitution relations among the products.
Further, after the target product is determined, the substitute chain to which the target product belongs can be determined according to the product information of the target product. The substitution chain comprises a plurality of products and substitution relations among the products. Such as the alternative chain shown in fig. 3, which includes 5 products, the alternative chain may also include alternative relationships between the respective products.
In actual application, the information of each product included in the substitute chain can be acquired, and then the total inventory amount is determined. The total inventory refers to the sum of the available inventory for each product included in the alternate chain. For example, the substitute chain includes 5 products in total, and the sum of the available stocks of the 5 products is the total stock quantity.
In this case, the inventory of the product is defined as unavailable, and in this case, the inventory of the product is not counted into the total inventory amount.
Specifically, the total inventory amount may be determined according to the substitution relationship in the substitution chain and the inventory information of each product.
Step 203, determining a target inventory amount and an inventory lower limit value according to the information of the plurality of products included in the substitute chain.
Furthermore, the target inventory can be determined according to the information of each product in the substitute chain. The target inventory amount is the inventory amount required to be prepared corresponding to the substitute chain. For example, the sales volume of each product in the substitute chain can be predicted, and the target inventory corresponding to the substitute chain can be determined according to the sales volumes of the products.
The determined target inventory may be a target inventory of individual products or a target total inventory of individual products in the alternate chain.
In actual application, the inventory amount of the product to be prepared is determined according to the actual sales condition of the product, so that the inventory can meet the sales usage amount, and overstock of the product can be avoided.
Wherein, a total sales amount can be determined according to the sales amount of each product in the substitute chain, and then the total sales amount is processed by using the existing model to obtain the target inventory amount. The sales volume of each product in the substitute chain can be processed by using the existing model, so that the target inventory corresponding to each product is obtained.
Specifically, the lower inventory limit is a threshold value below which the inventory amount may be considered insufficient to support normal sales of the products in the substitute chain, and at this time, replenishment of each product in the substitute chain may be performed.
For example, the inventory lower limit value may be determined according to the sales condition of each product in the substitute chain, for example, the inventory lower limit value may be obtained by determining the total sales amount according to the sales volume of each product in the substitute chain and processing the total sales amount according to the existing model.
In the practical application process, the time sequence of determining the total inventory amount, the target inventory amount and the lower limit value of the inventory is not limited.
And step 204, if the inventory amount is less than the inventory lower limit value, determining the replenishment quantity of each product in the substitute chain according to the target inventory amount and the inventory amount.
Further, if the total inventory amount corresponding to the substitute chain is lower than the lower inventory limit value corresponding to the substitute chain, it indicates that the inventory amount corresponding to the substitute chain is insufficient, and at this time, each product included in the substitute chain can be restocked, so that the inventory can be ensured to meet the sales demand.
In practical application, the total inventory amount is the number of existing products corresponding to the substitute chain, and the lower limit value of inventory is a threshold value corresponding to the substitute chain and capable of meeting the sales demand, so that when the total inventory amount is lower than the lower limit value of inventory, the current inventory does not meet the sales demand, and replenishment is required.
The replenishment quantity of each product included in the substitute chain can be determined according to the determined target inventory quantity and the total inventory quantity, so that each product can be replenished according to the determined replenishment quantity.
Specifically, after the product is restocked according to the restocking amount, the existing stock of the product meets the target stock.
Further, the inventory management system may also record various product packaging rules, order volume rules, and the like, and may revise the determined replenishment volume according to these rules. For example, if the replenishment quantity of the product a1 is 50 and the packing rule of the product a1 is 6, the replenishment quantity can be corrected to 54 so as to satisfy the actual stock approach.
In practical application, the inventory management system can generate a replenishment list according to the determined replenishment quantity, and then the inventory manager can perform replenishment processing according to the replenishment list.
In an alternative embodiment, the replenishment list may be sent to the supplier side, so that the supplier can deliver the goods to the warehouse according to the replenishment list.
The method provided by the embodiment is used for determining the replenishment quantity of a product, and is executed by a device provided with the method provided by the embodiment, and the device is generally implemented in a hardware and/or software manner.
The method for determining the replenishment quantity of the product provided by the embodiment comprises the following steps: acquiring inventory information of a warehouse and product information of products stored in the warehouse, and determining a target product according to the inventory information and the product information; determining the total inventory amount according to a substitution chain to which a target product belongs, wherein the substitution chain comprises a plurality of products and substitution relations among the products; determining a target inventory amount and an inventory lower limit value according to the information of a plurality of products included in the substitute chain; and if the inventory amount is less than the inventory lower limit value, determining the replenishment quantity of each product in the substitute chain according to the target inventory amount and the inventory amount. According to the method, the replenishment quantity of each product can be determined according to the substitution relation among the products and the information of the products, and the replenishment quantity of each product can be determined under the condition that the substitution relation exists among the products, so that the product inventory can be effectively managed.
FIG. 4 is a flow chart illustrating a method of determining a product replenishment quantity in accordance with another exemplary embodiment of the present application.
As shown in fig. 4, the method for determining the replenishment quantity of a product provided by this embodiment includes:
step 401, obtaining inventory information of a warehouse and product information of products stored in the warehouse.
The specific principle and implementation of step 401 are similar to those of step 201, and are not described herein again.
Step 402A, determining a tail piece product in the substitute chain according to the product information; and screening target products meeting the replenishment conditions from the tail products according to the inventory information.
The product information may include a substitute chain to which the product belongs, and may also include a substitute relationship with other products. Thus, the end piece product in the substitute chain can be determined from the product information.
In particular, the end piece product is the end product in the replacement chain, which can be used only for replacing other products, and not replaced by other products. The product may also have a two-way substitution relationship with other products, such as a first product at the end of a substitution chain and the first product may substitute for a second product, which may also substitute for the first product.
Further, with product changes, the end piece product can be considered the latest generation of products in the replacement chain.
In actual application, the target product can be screened from the end piece products according to the inventory information. The target product is a product meeting the replenishment condition. The replenishment condition may be set as required.
For example, the inventory information may include a black list and a white list, and if an end product appears in the black list, the end product does not meet the replenishment condition. For another example, the inventory information further includes the inventory amount of each commodity, and if the inventory amount of one end piece product is higher than a preset threshold, the end piece product may be considered to be not in accordance with the replenishment condition.
By the method, the target product meeting the replenishment condition can be determined according to the self condition of the product and the inventory information.
Step 402B, determining non-end-piece and inventory use forms in the substitute chain to be inventory self-use products only aiming at the product according to the product information; and determining a target product in the self-use products in the stock according to the stock information.
The product information may include a substitute chain to which the product belongs, and may also include a substitute relationship with other products. Thus, non-end piece products in the substitute chain can be determined from the product information.
Specifically, the product information may further include an inventory use form of the product, for example, the inventory use form is only used for the product, and may also be used in a unidirectional manner or a bidirectional manner.
Further, use only with respect to the present product means that inventory of one product is used only with respect to itself.
Fig. 5 is an alternate chain schematic shown in an exemplary embodiment of the present application.
As shown in fig. 5, product a4 replaces product A3, product A3 replaces product a2, product a2 can also replace A3, and product A3 replaces product a 1. The products A1, A2 and A3 are all non-end pieces.
There are also stock usage patterns between products, for example, if product a2 is used for the product only, then the stock of a2 cannot be used to replace other products when selling other products. For example, at the time of sale A3, shipment using a2 is not possible.
More specifically, the substitution relationship between products in the substitution chain is the substitution relationship between products in the product alternation process, and the stock use form is whether the stock of a single product can be provided for other products. For example, the stock of A3 is 3, the stock of a2 is 5, and when the sales number of A3 is 4, it cannot be replenished with the stock of a 2.
In practical application, if the inventory use form of the product is only used for the product, the product is determined to be an inventory self-use product, and the target product can be determined in the inventory self-use product according to the inventory information.
For example, the inventory information may include a black list and a white list, and if a product in inventory is present in the black list, it is not eligible for replenishment. For another example, the inventory information further includes the inventory amount of each commodity, and if the inventory amount of a self-service product in inventory is higher than a preset threshold, the self-service product in inventory can be considered to be not in compliance with the replenishment condition.
By the method, the target product meeting the replenishment condition can be determined according to the self condition of the product and the inventory information.
In step 403, if the first product in the substitute chain to which the target product belongs can replace the second product in the substitute chain, the inventory of the first product is determined as the available inventory.
Wherein a total amount of inventory corresponding to the alternate chain to which the target product belongs may be determined. Specifically, the available inventory of the alternate chain may be determined first.
Specifically, if a first product in the substitute chain can replace a second product in the substitute chain, it indicates that the first product can replace other products, and its inventory can be applied to other products in the substitute chain.
Furthermore, if the third product in the substitute chain does not substitute any other product, it indicates that the life cycle of the third product is finished, and after the inventory of the third product is emptied, the product is not sold any more, so the inventory of the third product can be used as the available inventory in the substitute chain.
In an alternative embodiment, a product may have stock in stock on hand, and may also have stock in transit. Stock-in-stock refers to the quantity of a product that is present in the warehouse and in-transit stock refers to the quantity of that product in transit to the warehouse. The sum of the in-stock inventory and the in-transit inventory of the first product may be determined as the available inventory of the first product.
For example, if the stock of a first product is M1 on the spot and M2 on the way, the sum of M1 and M2 can be used as the available stock of the first product.
In step 404, the sum of the available stocks corresponding to the substitute chain is determined as the total stock.
In actual application, the available stocks of the substitute chains are added to obtain the total stock corresponding to the substitute chains.
For example, if there are 5 products in the substitute chain, and only one product does not substitute any other product, it may be considered that there are 4 first products in the substitute chain, in this case, the stock of the 4 first products may be regarded as all available stock, and the sum of the stock of the four products may be regarded as the total stock corresponding to the substitute chain.
In an alternative embodiment, the total inventory amount is Sn；
Figure BDA0003140613370000101
Wherein S isiIs product AiIn stock, OiIs product AiIn-transit inventory of product AiWhen it is possible to substitute any one of the products of the chain, Li1, otherwise, Li＝0。
Specifically, when product A is preparediWhen any of the products on the alternate chain can be replaced, then product Ai is the first product and its inventory is available. Thus, by setting the coefficient LiWhether to determine the total inventory amount from the inventory of the product can be controlled.
Further, if product AiWhen any product in the chain can be replaced, then LiAt this point, the inventories of the products Ai are summed to determine the total inventory. Otherwise, LiThe inventory of product Ai is not used to determine the total inventory amount, 0.
In this way, each product in the substitute chain can be traversed, and whether the inventory of the product is adopted or not is determined according to the condition of the product to determine the inventory total amount of the substitute chain.
In the method provided by the present application, the target inventory amount may be determined based on steps 405 and 406, or may be determined based on step 407.
Step 405, a predicted total sales amount is determined based on sales information for each product included in the substitute chain.
In practical applications, the information of each product may further include product sales information, for example, the sales of the product may be in a period of time, such as a day sales, a week sales, and the like.
In one embodiment, sales for each product may be aggregated to obtain a predicted total sales corresponding to the alternate chain. Since the substitute chain comprises a plurality of products, and each product has its own sales information, the total sales of the whole substitute chain can be predicted according to the sales of the products in a period of time.
Step 406, determining a target inventory total amount and an inventory lower limit value according to the predicted total sales.
A model for determining the target inventory and the inventory lower limit value may be preset, and the obtained predicted total sales may be input into the model, so as to obtain the target inventory total amount and the inventory lower limit value of the substitute chain.
When each product in the substitute chain is restocked, the target inventory total that the inventory sum of the plurality of products included in the substitute chain should reach is reached. During the sales process, the inventory total of the plurality of products included in the alternate chain should be higher than the inventory lower limit value to meet the sales demand.
Step 407, determining a target inventory corresponding to each product and an inventory lower limit value of the substitute chain according to the sales amount information of each product included in the substitute chain.
In another embodiment, a model for determining the target inventory and the inventory lower limit value may be preset, and the sales information of each product in the substitution chain may be input into the model, so as to obtain the target inventory corresponding to each product in the substitution chain.
The model may also output an inventory lower limit value corresponding to each product, and the sum of these inventory lower limit values may be determined as the inventory lower limit value of the surrogate chain.
When each product in the alternate chain is restocked, the sum of the inventories of the plurality of products included in the alternate chain should reach the target inventory of the product. During the sales process, the sum of the inventories of the plurality of products included in the substitute chain should be higher than the lower inventory limit of the substitute chain to meet the sales demand.
In the method provided by the present application, if the inventory usage patterns among the products in the alternate chain include a one-way usage relationship and/or a two-way usage relationship, step 408 may be performed. If the inventory usage pattern for each product in the alternate chain is specific to that product only, then steps may be performed
And step 408, if the total inventory amount is smaller than the inventory lower limit value and the inventory use form among the products in the substitution chain comprises a one-way substitution relation and/or a two-way substitution relation, determining the splitting coefficient corresponding to each product in the substitution chain according to a preset rule.
If the total inventory amount determined in step 404 is less than the inventory lower limit determined in step 406 or 407, it indicates that the inventory of the current product does not meet the sales requirement and needs to be restocked.
Specifically, if the stock usage form of each product included in the substitute chain is a one-way substitution relationship or a two-way substitution relationship, it indicates that the stock of the product in the substitute chain can be substituted by other products, and in this case, the splitting coefficient of each product in the substitute chain can be determined according to a preset rule.
Fig. 6 is a schematic diagram of an alternate chain shown in yet another exemplary embodiment of the present application.
As shown in fig. 6, in the process of product update iteration, product a4 may replace product A3, product A3 may replace product a2, product a2 may also replace A3, and product A3 may also replace product a 1.
In addition, the products have stock use forms, for example, the stock of the product A4 can be used by the product A3, and the stock use form between the A4 and the A3 is a one-way replacement. The inventory of product A3 may be used by product a2, the inventory of product a2 may be used by product A3, and the inventory between A3 and a2 may be used in a two-way replacement. The inventory of product A3 may be used by product a1, with the inventory between A3 and a1 being used in one-way replacement.
If the inventory usage form among the products in the replacement chain is the one-way replacement and/or the two-way replacement, the inventory of some products in the replacement chain can be used by other products, and therefore, the products can be restocked.
Preset rules can be preset for determining the splitting coefficient of the product. For example, the splitting coefficient may be determined according to the sales condition of each product, for example, if the product is sold at a high sales rate, the splitting coefficient is also large.
Specifically, if the stock of the third product in the substitute chain cannot be replaced by any fourth product in the substitute chain, it indicates that the third product is to be replaced by another product after the third product is sold, and therefore, the third product may not be restocked, and the splitting coefficient of the third product may be set to 0. The third and fourth are used to broadly refer to two different products in the replacement chain.
Further, if the inventory of the first product can be used by any second product in the replacement chain, it indicates that the life cycle of the first product is not over, and the first product can be restocked.
In practical application, the sum of the splitting coefficients of the products in the substitution chain is 1.
For example, if product AiWhen it is possible to substitute any one of the products of the chain, Li1, otherwise, Li0. Then may be at L of the productiWhen the value is 0, the resolution coefficient r of the product is determinediIs set to 0. If a total of n products are included in the chain of alternatives, then
Figure BDA0003140613370000121
Step 409, determining the total replenishment quantity according to the target inventory and the total inventory quantity.
Such as may be determined based on the target inventory obtained in steps 405-406.
The target inventory is determined inventory which can meet the predicted sales volume, and the total inventory is the current existing inventory, so that the difference between the target inventory and the total inventory can be used as the total replenishment quantity.
For example, total replenishment Pn is:
Figure BDA0003140613370000122
where Tn replaces the target inventory of chains.
And step 410, determining the replenishment quantity of each product in the substitute chain according to the splitting coefficient and the total replenishment quantity.
Specifically, the total replenishment amount is the sum of the replenishment amounts of the products in the substitute chain, for example, the substitute chain includes 4 products, the replenishment amounts of the 4 products are respectively C1, C2, C3 and C4, and the sum of C1, C2, C3 and C4 is the total replenishment amount.
Further, the total restocking needs to be distributed to each product, so as to obtain the restocking amount of each product included in the substitute chain. For example, the product of the splitting coefficient and the total replenishment quantity of each product included in the substitute chain may be used as the replenishment quantity corresponding to each product.
In practical application, the splitting coefficient is a replenishment quantity coefficient of each product determined based on a preset rule and is related to information of each product, so that the product of the splitting coefficient of each product and the total replenishment quantity can be used as the replenishment quantity corresponding to each product. This way the total amount of restocking can be reasonably distributed to each product.
Step 411, if the total inventory amount is smaller than the inventory lower limit value, and the inventory usage form of each product in the substitute chain is only for the product, determining the replenishment amount of each product in the substitute chain according to the target inventory and the existing inventory corresponding to each product in the substitute chain.
If the total inventory amount determined in step 404 is less than the inventory lower limit determined in step 406 or 407, it indicates that the inventory of the current product does not meet the sales requirement and needs to be restocked.
Specifically, if the stock usage form of each product included in the substitute chain is only for the product, it indicates that the stock of the product in the substitute chain cannot be used by other products, and in this case, the replenishment quantity of each product included in the substitute chain may be determined according to the target stock and the existing stock of each product in the substitute chain.
Fig. 7 is a schematic diagram of an alternate chain shown in yet another exemplary embodiment of the present application.
As shown in fig. 7, in the process of product update iteration, product a4 may replace product A3, product A3 may replace product a2, product a2 may also replace A3, and product A3 may also replace product a 1.
In addition, the products have stock use forms, for example, the stock use forms of the products A1, A2, A3 and A4 are all only used for the product.
If the stock use form of each product in the substitute chain is only used for the product, the stock of each product in the substitute chain cannot be used by other products, so that the latest product in the substitute chain can be restocked, and other products are not restocked.
The replenishment quantity of each product included in the substitute chain can be determined specifically according to the target inventory and the existing inventory corresponding to each product in the substitute chain.
In one embodiment, the demand corresponding to each product may be determined based on the target inventory, the existing inventory, of the respective product. For example, the demand corresponding to each product may be determined based on the target inventory of the respective product determined in step 408 and the existing inventory of the products.
For example, the demand Pi for product Ai is:
Pi＝ti-(Si+Oi)
further, the sum of the demanded quantities of the respective products may be used as the replenishment quantity of the end product in the substitute chain, and the replenishment quantity of the other products in the substitute chain may be determined to be 0. For example, if the substitute chain includes n products in total, the replenishment quantity Pn of the end piece product An is:
Figure BDA0003140613370000141
in this embodiment, products whose inventory cannot be applied to other products are not restocked, and only the latest product is restocked, so that inventory of products with an earlier update time in the replacement chain can be emptied as soon as possible, and more inventory can be released to the latest product.
And step 412, acquiring purchasing information corresponding to each product in the substitute chain, and correcting the replenishment quantity of each product according to the purchasing information.
In an optional implementation manner, the electronic device may further obtain purchase information of each product in the substitute chain, for example, purchase information corresponding to each product may be set in the warehouse management system.
The procurement information includes, for example, the order amount of the product, and may also include packaging information for the product. The determined replenishment quantity can be corrected according to the purchasing information.
Since the determined replenishment quantities for the respective products may not satisfy the product order amount, the replenishment quantities may be corrected according to the order amount such that the corrected replenishment quantities are greater than or equal to the order amount. For example, if the order amount of a product is 500 and the replenishment quantity of the product is 450 based on the above steps, the replenishment quantity of the product may be corrected to 500.
It is also possible that the number of products does not comply with the packaging rules of the products, and therefore, the replenishment quantity can be corrected according to the packaging information of the products. For example, if the replenishment quantity of a product is 310 but the packing information of the product is 40 boxes, the current replenishment quantity cannot be purchased in the whole box, and therefore, the replenishment quantity of the product can be corrected to 320 boxes.
By the method, the corrected product replenishment quantity can accord with the purchasing rule, so that replenishment can be directly performed according to the corrected product replenishment quantity.
In a specific embodiment, the substitute chain includes A1-A7These 7 products. Wherein, in the iterative process of product updating, A2Substitution A1，A5Substitution A2，A5Substitution A3，A3Can also replace A5，A5Substitution A4，A4Can also replace A5，A7Substitution A5，A5Can also replace A7，A7Can also replace A6。
The replenishment quantities of the respective products are determined without considering the substitution relationship among the products as follows:
commodity Sales prediction Stock in stock Stock in transit Target inventory Amount of replenishment
A1 5 12 6 25 7
A2 8 20 12 40 8
A3 6 18 6 30 6
A4 4 8 10 20 2
A5 6 22 8 30 0
A6 5 16 12 25 7
A7 2 10 4 10 0
When the stock use form of the product is consistent with the substitution relationship during the update of the product, if the substitution relationship between the products is considered, A7The sales forecast is the sum of the sales of the replaced goods and the sales itself, i.e. 36, A7Is a bidirectional relationship among the alternative relationships of the stock-in-stock and the stock-in-transit3、A5、A7Are 50 and 18, respectively, as A7Inventory model calculation of A7The target inventory is 180. Based on this, the determined replenishment amounts are as follows:
Figure BDA0003140613370000151
Figure BDA0003140613370000161
when the stock use forms of all the products in the substitution chain are only specific to the product, A can be respectively determined1～A7Calculating target inventory and replenishment quantity, wherein the replenishment quantity of the tail piece at the end of the substitute chain is the sum of the replenishment quantity values of all products on the substitute chain; the replenishment quantity of other commodities except the tail part is 0. A. the1～A7The replenishment quantity is:
Figure BDA0003140613370000162
comparing the above tables, it can be found that when the stock usage form of the substitute chain is in a one-way or two-way relationship, the replenishment quantity is larger than that in the case of not considering the substitute chain, and the reason for this phenomenon is that the stock of the commodity is no longer sold to the market, that is, the stock is not available, considering that the commodity in the substitute chain is released from the market along with the life cycle of the commodity. This phenomenon corresponds to the situation where the stock usage pattern of the substitute chain is uni-directional and bi-directional and the relationship type is unidirectional, so that more goods need to be supplied to satisfy the sales of the substitute goods.
Comparing the three tables above, A without considering the alternate chain7The replenishment quantity is 0; in consideration of the replacement chain, the end piece (generally, the newest piece) of the replacement chain is restocked regardless of the stock use form.
