[0055] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0056] The embodiments of the present application provide a method, device, equipment and medium for generating a product data list, so as to improve the generation efficiency and accuracy of the product data list and avoid the problems of great waste of man-hours and high error rate caused by repeated manual operations.

[0057] Among them, the method and the device, equipment, and medium are based on the same application concept. Since the principles of solving problems by the method and the device, equipment, and medium are similar, the implementation of the device, equipment, medium, and method can refer to each other, and the repeated parts will not be repeated.

It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments described herein can be implemented in a sequence other than the content illustrated or described herein.

[0059] The following examples and embodiments are to be understood as illustrative examples only. Although this specification may refer to "one", "an" or "some" examples or embodiments in several places, this does not mean that each such reference relates to the same example or embodiment, nor does it mean that the feature applies only to a single example or embodiment.

[0060] The following is a detailed description of each embodiment of the present application in conjunction with the accompanying drawings. It should be noted that the display order of the embodiments of the present application only represents the order of the embodiments, and does not represent the advantages and disadvantages of the technical solutions provided by the embodiments.

[0061] See also Figure 1 , a method for generating a product data list provided in an embodiment of the present application includes:

[0062] S101, determining a bill of materials structure of a target product, wherein the bill of materials structure includes at least one level of category modules, wherein the category modules are used to fill materials, and category modules at the same level are used to fill materials of the same category;

[0063] The bill of materials structure of the target product, that is, for the product that currently needs to generate a bill of materials data, first generates the architecture of its bill of materials, which can include multiple category modules. Each category module can be filled with the corresponding category of material information in subsequent steps. After it is finally filled, the bill of materials of the target product is generated.

[0064] S102, based on a preset bill of materials model, determining the main material required by the target product, and filling the main material into the corresponding category module in the bill of materials structure of the target product, and filling other materials required by the target product into the corresponding category module in the bill of materials structure of the target product, and finally generating the bill of materials of the target product;

[0065] The bill of materials model includes:

[0066] A pre-set product bill of materials structure, which includes at least one level of category modules, and each category module is filled with at least one material of the same category;

[0067] The correspondence between pre-set specification attributes and materials;

[0068] The pre-set reference frequency of each material corresponding to each of the specification attributes;

[0069] The pre-set compatibility coefficients between materials in different categories of modules, wherein the compatibility coefficients are used to characterize the frequency of the mutual coordination of materials in different categories of modules.

[0070] That is to say, the embodiment of the present application can pre-set a bill of materials, including material information of different hierarchical structures, that is, different category modules correspond to different specification attributes, material sets, etc. In addition, the reference frequency of each material corresponding to each specification attribute and the compatibility coefficient between materials in different category modules can also be obtained in advance based on data statistics. Therefore, the embodiment of the present application can support the automatic matching of bills of materials of different products in actual applications based on the preset bill of materials model, and the workload of data maintenance is relatively small.

[0071] In the embodiment of the present application, based on the derived requirement specification attributes and bill of materials structure of the new product, the existing bill of materials model can be used to automatically match and fill in materials to generate a new derived product bill of materials. Therefore, the manual work can be greatly reduced and the efficiency and accuracy of generating the product bill of materials can be improved.

[0072] In some embodiments, see Figure 2 , pre-setting the bill of materials model, including:

[0073] S201, obtaining the full product bill of materials data of the target product lifecycle management system (Product Lifecycle Management, PLM);

[0074] For example, the full product bill of materials data includes: historical inventory data and regularly extracted incremental data (referred to as extracted incremental data).

[0075] S202: Determine a bill of materials structure based on the full product bill of materials data;

[0076] The bill of materials structure includes category modules under at least one level, and each level includes at least one category module.

[0077] The category modules, such as printed circuit board assembly (PCBA), optics, hardware, structure, packaging, accessories and other category modules, are used to fill in different categories of materials.

[0078] For example, see Figure 3 The bill of materials structure includes: a material hierarchy structure of three levels: 1, 2, and 3, and category modules A to category modules E under each level.

[0079] S203, establishing a correspondence between each of the category modules and specification attributes;

[0080] For example, it includes labeling and defining the specification attributes of each category of modules.

[0081] The specification attributes include, for example: functional specifications (such as 2 million pixels), appearance specifications (such as black appearance), etc.

[0082] S204, establishing the corresponding relationship between each specification attribute and the material;

[0083] For example, specification attribute a (e.g. 2 million pixels) corresponds to material a_1, material a_2, and material a_3;

[0084] Specification attribute b1 (for example, black appearance) corresponds to materials b1_1 and b1_2.

[0085] After executing steps S203 and S204, it is equivalent to filling at least one material of the same category in each category module of the bill of materials structure determined in S202.

[0086] S205. For each material corresponding to each specification attribute, determine the reference frequency of the material;

[0087] For example, according to the correspondence between each specification attribute and the material, the material reference frequency can be aggregated (i.e., counted) according to each specification attribute, and the reference frequency of each material corresponding to each specification attribute can be determined;

[0088] For example, different products satisfy specification attribute a, among these products:

[0089] 20% of the products reference material a_1;

[0090] 70% of the products reference material a_2;

[0091] 10% of products reference material a_3;

[0092] Then, the reference frequencies of various materials corresponding to specification attribute a are:

[0093] Material a_1: 0.2;

[0094] Material a_2: 0.7;

[0095] Material a_3: 0.1.

[0096] S206. Determine the compatibility coefficients between materials in different categories of modules.

[0097] For example, the compatibility coefficients between materials in different categories of modules can be determined based on algorithms such as association rule mining and decision trees.

[0098] Specifically, for example:

[0099] Specification attribute a (2 million pixels) corresponds to material a_1, material a_2, and material a_3;

[0100] Specification attribute b1 (black appearance) corresponds to material b1_1, material b1_2, and material b1_3;

[0101] Specification attribute b2 (black appearance) corresponds to material b2_1, material b2_2, and material b2_3;

[0102] The training history data is available for products that meet the following requirements (2 megapixels, black appearance):

[0103] 20% references both material a_1 and material b1_2;

[0104] 30% references both material a_1 and material b1_3;

[0105] 10% references both material a_2 and material b2_2;

[0106] 40% references both material a_3 and material b2_3;

[0107] Then, the compatibility coefficient between materials is as follows:

[0108] a_1, b1_2: 0.2;

[0109] a_1, b1_3: 0.3;

[0110] a_2, b2_2: 0.1;

[0111] a_3, b2_3:0.4.

[0112] S207. Build a bill of materials model.

[0113] For example, the following can be generated based on the BOM structure, the correspondence between specification attributes and materials, the material reference frequency in specification attributes, and the compatibility coefficient between materials: Figure 3 The bill of materials model shown is used to quickly generate a product bill of materials.

[0114] The material reference frequency within the specification attribute is the usage frequency of different materials that meet the same specification attribute, for example:

[0115] The reference frequency of material a_1 corresponding to specification attribute a: 0.2;

[0116] The reference frequency of material a_2 corresponding to specification attribute a is 0.7;

[0117] The reference frequency of material b1_1 corresponding to specification attribute b1 is 0.1;

[0118] …

[0119] The material compatibility coefficient is the frequency of using different materials that meet multiple specification attributes together, for example:

[0120] The compatibility coefficient between material a_1 and material b1_2: 0.2;

[0121] The compatibility coefficient between material a_1 and material b1_3 is 0.3;

[0122] The compatibility coefficient between material a_2 and material b2_2: 0.1;

[0123] …

[0124] In some embodiments, determining the main materials required for the target product based on a preset bill of materials model includes:

[0125] Based on the preset corresponding relationship between the specification attributes of the product and the material, and the preset reference frequency of each material corresponding to each of the specification attributes, the main material required by the target product is determined.

[0126] In some embodiments, the determining of the main material required for the target product based on the preset correspondence between the specification attributes of the product and the material, and the preset reference frequency of each material corresponding to each of the specification attributes, includes:

[0127] Based on the preset correspondence between the specification attributes of the product and the materials, determining the materials corresponding to the target specification attributes of the target product requirements;

[0128] Based on the preset reference frequencies of various materials corresponding to the target specification attributes, the material with the highest reference frequency corresponding to the target specification attributes is determined as the main material required by the target product.

[0129] In some embodiments, filling other materials required by the target product into corresponding category modules in the bill of materials structure of the target product includes:

[0130] For each category module other than the category module corresponding to the main material in the bill of materials structure of the target product (for example, each category module can be processed separately in order of distance from the category module corresponding to the main material from near to far), determine the material in the category module of the preset product bill of materials structure corresponding to the category module, select materials from the materials in the category module based on the preset fitness coefficient between each material in the category module and the main material (for example, select the material with the largest fitness coefficient with the main material), and fill the selected materials into the corresponding category module in the bill of materials structure of the target product until the material filling of each category module in the bill of materials structure of the target product is completed, and finally generate the bill of materials of the target product.

[0131] In some embodiments, the method further comprises:

[0132] Determine the finally generated bill of materials of the target product as the bill of materials of the parent product (for example, copy the finally generated bill of materials of the target product as the bill of materials of the parent product);

[0133] Determine the materials in the material list of the parent product that do not conform to the specification attributes currently required by the new target product, and delete them from the material list of the parent product to obtain an initial material list of the new target product;

[0134] Determine the main material required for the new target product based on the correspondence between the preset product specification attributes and the material, and the reference frequency of each material corresponding to each preset specification attribute;

[0135] Fill the main materials currently required by the new target product into the corresponding category module in the initial bill of materials of the new target product;

[0136] Based on the compatibility coefficient of each material except the main material in the initial bill of materials of the new target product and the main material in the initial bill of materials of the new target product, the initial bill of materials of the new target product is updated to finally generate the bill of materials of the new target product.

[0137] In some embodiments, based on the compatibility coefficient of each material except the main material in the initial bill of materials of the new target product and the main material in the initial bill of materials of the new target product, updating the initial bill of materials of the new target product includes:

[0138] For each material except the main material in the initial bill of materials of the new target product, determine the compatibility coefficient between the material and the main material in the initial bill of materials of the new target product, and judge whether the compatibility coefficient is greater than a preset threshold value. If so, retain the material in the initial bill of materials of the new target product; otherwise, replace the material in the initial bill of materials of the new target product, wherein the compatibility coefficient between the replaced material and the main material in the initial bill of materials of the new target product is greater than the preset threshold value.

[0139] It can be seen that in the embodiment of the present application, the generated product bill of materials can also be used as the bill of materials of the parent product, and based on this, the material can be automatically matched, filled and replaced on the basis of the specification attributes of the parent product, the reformed derived demand, the reformed derived bill of materials structure, and the preset bill of materials model to generate the reformed derived product bill of materials, that is, the latest required product bill of materials. This can further save manpower and material resources, save time, improve work efficiency, reduce the error rate of product bill of materials data, and greatly avoid product bill of materials data errors caused by human factors.

[0140] Two specific embodiments of the method for generating a product data list are given below.

[0141] See also Figure 4 The method for generating a product data list provided in the embodiment of the present application includes:

[0142] S401. Determine the bill of materials structure of the new derivative product and expand it layer by layer;

[0143] For example, based on product lines, product types, sales regions and other conditions, determine the bill of materials structure of a new derivative product (i.e., the current target product) and expand it layer by layer;

[0144] For example, the BOM structure of a new derivative product could be the same as Figure 3 The product bill of materials structure shown is the same structure. Of course, it can also be a different structure. Different products can correspond to different hierarchical structures, for example Figure 5 , Figure 6 As shown, in this embodiment, it is assumed that the bill of materials structure of the new derivative product is Figure 6 The structure shown is shown, and the subsequent steps are performed.

[0145] S402. Determine the material with the highest reference frequency as the main material required for the new derivative product.

[0146] According to the preset BOM model, the correspondence between the preset specification attributes and the materials and the reference frequency of each material corresponding to each of the preset specification attributes, the material with the highest reference frequency corresponding to the specification attributes of the current demand is determined as the main material for the new derivative product demand.

[0147] For example, the specification attribute of the current demand is specification attribute a (2 million pixels), and the material a_2 corresponding to specification attribute a has the highest reference frequency. Therefore, the main material of the new derivative product demand is material a_2.

[0148] S403. Fill the main materials into the corresponding category module to obtain the initial material list of the new derivative product.

[0149] That is, based on the preset product BOM structure, the main materials required for the new derivative product are filled into the corresponding category modules in the BOM structure of the new derivative product determined in step S401 to obtain the initial BOM of the new derivative product.

[0150] For example, Figure 3 As shown, based on the preset product bill of materials structure, the main material a_2 is determined, and the main material a_2 corresponds to the category module A, and the main material a_2 is filled into the category module A determined in S401. Figure 6 The corresponding category module A in the material list hierarchy structure shown in the figure is obtained as follows Figure 7 Initial bill of materials for the new derivative product shown.

[0151] S404. Fill the materials into each category module according to the hierarchical distance from near to far and the principle of relatively optimal fit coefficient between materials.

[0152] The hierarchical distance is from near to far, for example, see Figure 7 , select materials and fill them into category module B~category module E respectively.

[0153] The principle of relatively optimal inter-material fitness coefficient is as follows, for example, the inter-material fitness coefficient value of each category module is the largest, or the inter-material fitness coefficient of each category module is higher than a critical value (i.e., a preset threshold value), etc.

[0154] For example, if the closest hierarchical distance to the main material a_2 is category module B, and the material b2_2 in category module B has the largest compatibility coefficient with the main material a_2, then fill material b2_2 into Figure 7 In the category module B shown, Figure 8 shown.

[0155] S405: Determine whether the bill of materials is complete. If so, end. Otherwise, continue to execute step S404. That is, by looping step S404 until Figure 7 All category modules in the bill of materials structure shown are fully filled to obtain the final bill of materials for the new derivative product, for example Fig. 9 shown.

[0156] In another embodiment, see Fig.10 The method for generating a product data list provided in the embodiment of the present application includes:

[0157] S301. Determine the bill of materials of the parent product and the specification attributes required by the current target product.

[0158] For example, the product bill of materials determined in the previous embodiment is determined as the bill of materials of the parent product of the current target product;

[0159] Assume that in this embodiment, the specification attribute required by the current target product is specification attribute A1 (eg, 4 million pixels).

[0160] S302, expanding the material list of the parent product layer by layer;

[0161] After expanding the material bill structure of the parent product layer by layer, we get Fig. 9 The structure shown.

[0162] S303, traverse the category modules of the material list structure of the parent product to determine the materials that do not meet the specification attributes required by the current target product.

[0163] For example, the specification attribute of the parent product is A (for example, 2 million pixels), and the specification attribute of the current target product requirement is A1 (for example, 4 million pixels). Therefore, the material a_2 of the parent product does not meet the specification attribute A1 required by the current target product.

[0164] S304, copying the bill of materials of the parent product, and removing the materials that do not meet the specification attributes required by the current target product from the copied bill of materials, to obtain an initial bill of materials for the current target product;

[0165] That is, keep the hierarchical structure of the parent product's bill of materials and the remaining materials to generate the initial bill of materials. Fig. 9 Eliminate material a_2 from the structure shown, and we get Fig.11 BOM shown.

[0166] S305. Determine the main material of the current target product.

[0167] For example, based on the preset bill of materials model, the reference frequency of the material corresponding to the specification attribute A1 (e.g., 4 million pixels) required by the current target product is determined as follows:

[0168] The citation frequency of material a1_1: 0.2;

[0169] The reference frequency of material a1_2: 0.3;

[0170] The citation frequency of material a1_3: 0.4;

[0171] The reference frequency of material a1_4: 0.1;

[0172] Then determine that the main material of the current target product is a1_3.

[0173] S306. Fill the main material of the current target product into the category module in the corresponding level of the initial bill of materials according to its category module, and generate a bill of materials to be updated.

[0174] For example, the bill of materials to be updated is as follows: Fig.12 shown.

[0175] In the subsequent steps, it is necessary to update the initial bill of materials of the current target product (updated based on the preset bill of materials model) based on the compatibility coefficient of each material in the initial bill of materials of the current target product except the main material with the main material of the current target product (determined based on the preset bill of materials model), and finally generate the bill of materials of the new target product.

[0176] S307.

[0178] For example, the compatibility coefficient between material b2_2 and material a1_3 is greater than the preset value, so it is retained.

[0179] S309. Delete the materials in the category module and replace them with materials with relatively optimal fitness coefficients.

[0180] For example, based on the preset bill of materials model, it is determined that the compatibility coefficient between material c_5 and material a_1 is less than the preset value, while the compatibility coefficient between material c_1 and material a_1 is greater than the preset value. Therefore, material c_5 is replaced with material c_1, and the following is obtained: Fig.13 BOM shown.

[0181] S310. Determine whether the bill of materials of the current target product is complete. If so, end. Otherwise, loop to execute step S307 until the materials in all category modules on the bill of materials of the current target product are checked against the preset values ​​for the fitness coefficients of the main materials, and the replacement of the materials is completed to obtain the final bill of materials of the current target product.

[0182] That is, for each material except the main material in the initial bill of materials of the new target product, determine the compatibility coefficient between the material and the main material in the initial bill of materials of the new target product, and judge whether the compatibility coefficient is greater than a preset threshold value. If so, retain the material in the initial bill of materials of the new target product; otherwise, replace the material in the initial bill of materials of the new target product, wherein the compatibility coefficient between the replaced material and the main material in the initial bill of materials of the new target product is greater than the preset threshold value.
