[0075] or,

[0076] If the product name in the technical requirements of the product requires the use of a specified historical product name, the historical product name will be called and a number will be added after the historical product name as the product name.

[0077] Specifically, the product requirements in the technical requirements of the product include:

[0083] Specifically, each product parameter in the product requirements is a specification of a product parameter that can be produced by the production equipment.

[0084] Step S102: constructing product material data and production process data based on product information;

[0085] Specifically, the material data and production process data of the product are constructed based on the product information, including:

[0086] Based on the product information, determine all existing virtual material data corresponding to the product information;

[0087] Based on the product information, determine whether you need to create at least one virtual item:

[0088] If the judgment is yes, at least one virtual item material is newly created, and parameter data corresponding to each virtual item material is determined, and material data of the product is constructed by using the at least one newly created virtual item material, the parameter data corresponding to each virtual item material, and all existing virtual item material data corresponding to the product information;

[0091] In the above embodiment, whether at least one virtual material needs to be newly created is determined through product information, thereby realizing automatic conversion, automatic inspection and creation of virtual materials, and improving the security of product material data and product production process data.

[0092] Specifically, judging whether it is necessary to create at least one virtual item material based on the product information includes:

[0093] If there is any product requirement in the product information that cannot correspond to the existing virtual item material data, it is determined that a new virtual item material needs to be created for the product requirement in the product information;

[0094] Otherwise, it is determined that there is no need to create at least one virtual material.

[0095] Step S103: Substituting the product information, the material data of the product and the production process data of the product into the production BOM generation module to obtain an automatically generated product BOM solution corresponding to the product information, wherein the product BOM solution at least includes a bill of materials corresponding to the product and parameter data corresponding to each material;

[0096] Specifically, the product information, the material data of the product and the production process data of the product are substituted into the production BOM generation module to obtain the automatically generated product BOM solution corresponding to the product information, including:

[0097] Based on the material data of the product, determine the physical materials corresponding to each virtual material in the material data of the product and the consumption corresponding to each physical material to form a bill of materials corresponding to the product;

[0098] Generate the product processing step route and parameter data of the virtual material corresponding to each step based on the product's production process data;

[0099] Based on the bill of materials corresponding to the product, the processing step route of the product and the parameter data of the virtual material corresponding to each step, the parameter data corresponding to each material is generated, wherein the parameter data at least includes the position of the processing step corresponding to the material, the consumption of the real material corresponding to the position of the processing step and the processing parameters of the real material corresponding to the position of the processing step;

[0100] The product BOM solution corresponding to the product information is constructed with the bill of materials corresponding to the product and the parameter data corresponding to each material.

[0101] Specifically, the product BOM solution corresponding to the product information is formed by using the bill of materials corresponding to the product and the parameter data corresponding to each material, including:

[0102] Based on the bill of materials corresponding to the product and the parameter data corresponding to each material, generate multiple sets of product BOM solutions corresponding to the product information;

[0103] Get the current material storage data of the material platform and the executable data of the material platform;

[0104] Based on the current material storage data of the material platform and the executable data of the material platform, multiple groups of product BOM solutions corresponding to the product information are screened to obtain the screened multiple groups of product BOM solutions corresponding to the product information;

[0105] The screened multiple groups of product BOM solutions corresponding to the product information are simulated, and a group of product BOM solutions is selected as the product BOM solution corresponding to the product information for output.

[0106] Specifically, simulating the screened multiple groups of product BOM solutions corresponding to the product information and selecting a group of product BOM solutions as the product BOM solution corresponding to the product information for output includes:

[0107] Simulating the selected multiple groups of product BOM solutions corresponding to the product information to obtain product simulation data corresponding to each group of product BOM solutions, wherein the product simulation data includes the number of several simulated products and product data of each simulated product;

[0108] Based on the product simulation data corresponding to each set of product BOM solutions, selectively determine the product completion and product accuracy corresponding to each set of product BOM solutions;

[0109] Based on the product completion and product accuracy corresponding to each group of product BOM solutions, a group of product BOM solutions with the highest product accuracy and whose product completion reaches a preset product completion threshold are selected and output as the product BOM solutions corresponding to the product information.

[0110] Specifically, the simulation technology for simulating the multiple groups of product BOM solutions corresponding to the product information after screening can adopt the simulation technology in the existing technology, or it can be a trained neural network model. The choice of simulation technology here is only an exemplary explanation. In actual testing, technical personnel in this field can make a choice according to actual needs. As long as it is possible to simulate the multiple groups of product BOM solutions corresponding to the product information after screening and obtain the product simulation data corresponding to each group of product BOM solutions, it will not be repeated here.

[0111] Specifically, the selectively determining the product completion and product accuracy corresponding to each group of product BOM solutions based on the product simulation data corresponding to each group of product BOM solutions includes:

[0112] Compare each simulated product in the product simulation data corresponding to each group of product BOM solutions with the product requirements in the product information to obtain the completion and accuracy of each simulated product corresponding to each group of product BOM solutions;

[0113] Perform cluster analysis on the completion and accuracy of each simulated product corresponding to each group of product BOM solutions to obtain the cluster completion and cluster accuracy corresponding to each group of product BOM solutions;

[0114] If the clustering completion degree corresponding to the product BOM solution is lower than the preset minimum clustering completion degree threshold, or the clustering accuracy rate corresponding to the product BOM solution is lower than the preset minimum clustering accuracy rate threshold, the product BOM solution is eliminated;

[0115] Furthermore, if the clustering completion degree corresponding to the product BOM solution exceeds a preset clustering completion maximum threshold, or the clustering accuracy rate corresponding to the product BOM solution exceeds a preset clustering accuracy maximum threshold, the product BOM solution is retained, or the eliminated product BOM solution is retained again;

[0116] To obtain multiple groups of screened product BOM solutions;

[0117] Based on the completion and accuracy of each simulated product corresponding to each group of product BOM solutions that have been screened, determine the average completion and average accuracy corresponding to each group of product BOM solutions that have been screened;

[0118] If the average completion degree corresponding to the product BOM solution is lower than the preset average completion degree threshold, the product BOM solution is eliminated;

[0119] If the average accuracy rate corresponding to the product BOM solution is lower than the preset average accuracy rate threshold, the product BOM solution is eliminated;

[0120] In order to obtain multiple groups of product BOM solutions after secondary screening;

[0121] Based on the average completion and cluster completion of each group of product BOM solutions that have been screened twice, determine the product completion corresponding to each group of product BOM solutions that have been screened twice;

[0122] Based on the average accuracy and clustering accuracy corresponding to each group of product BOM solutions that have undergone secondary screening, the product accuracy corresponding to each group of product BOM solutions that have undergone secondary screening is determined.

[0123] Specifically, the preset minimum threshold of clustering completion can be 50% or 60%, the preset maximum threshold of clustering completion can be 70% or 75%, the preset minimum threshold of clustering accuracy can be 75% or 80%, and the preset maximum threshold of clustering accuracy can be 85% or 90%. The settings of the preset minimum threshold of clustering completion, the preset maximum threshold of clustering completion, the preset minimum threshold of clustering accuracy, and the preset maximum threshold of clustering accuracy are only exemplary descriptions. In actual tests, those skilled in the art can make settings according to actual needs, which will not be repeated here.

[0124] Specifically, the preset average completion threshold can be 60% or 70%, and the preset average accuracy threshold can be 75% or 80%. The settings of the preset average completion threshold and the preset average accuracy threshold here are only exemplary. In actual tests, those skilled in the art can set them according to actual needs, which will not be elaborated here.

[0125] Specifically, the product completion and product accuracy are obtained through the following formula:

[0126] Product completion = average completion * preset weight corresponding to average completion + cluster completion * preset weight corresponding to cluster completion;

[0127] Product accuracy = average accuracy * preset weight corresponding to average accuracy + cluster accuracy * preset weight corresponding to cluster accuracy.

[0128] Among them, the preset weight corresponding to the average completion degree, the preset weight corresponding to the clustering completion degree, the preset weight corresponding to the average accuracy rate, and the preset weight corresponding to the clustering accuracy rate can be 0.7, 0.3, 0.6, 0.4, or all of them can be 0.5. The setting of the preset weight corresponding to each type of data here is only an exemplary description. In actual testing, technical personnel in this field can set it according to actual needs, which will not be repeated here.

[0129] Specifically, based on the product completion and product accuracy corresponding to each group of product BOM solutions, a group of product BOM solutions with the highest product accuracy and a product completion reaching a preset product completion threshold are selected as the product BOM solutions corresponding to the product information and outputted, including:

[0130] Select a group of product BOM solutions with the highest average completion rate and a group of product BOM solutions with the highest average accuracy from multiple groups of product BOM solutions that have been screened twice;

[0131] If the two groups of product BOM solutions are the same group of product BOM solutions, the product BOM solutions are output as the product BOM solutions corresponding to the product information;

[0132] If the two groups of product BOM solutions are inconsistent, the group of product BOM solutions with the highest average accuracy is selected, and the group of product BOM solutions whose product completion reaches the preset product completion threshold is output as the product BOM solution corresponding to the product information.

[0133] Specifically, the preset product completion threshold may be 85% or 90%. The setting of the preset product completion threshold here is only an example. In actual testing, those skilled in the art may set it according to actual needs, which will not be elaborated here.

[0134] In the above embodiment, in the model processing, the material data of the product is used to determine the actual material machine consumption corresponding to each virtual material in the material data of the product, and the bill of materials of the product is formed to realize the automatic acquisition of the bill of materials of the product. Then, through the production process of the product, the processing step route of the product and the parameter data of the virtual material of each step are generated. Then, based on the acquired data, the parameter data of each material is generated, and then the product BOM solution corresponding to the product information is formed, thereby realizing the automatic generation of the product BOM solution, ensuring that the product BOM solution matches the product, improving the generation efficiency of the product BOM solution, and thus improving the production efficiency of the product.

[0135] Step S104: The product information and the product BOM solution corresponding to the product information are stored in the product BOM database of the material platform, thereby shortening the generation time of the product BOM solution, improving work efficiency and improving the accuracy of the product BOM.

[0136] It is not difficult to find that compared with the related art, in the solution provided in the embodiment of the present application, the material data and production process data of the product are constructed by acquiring the product information, and the product information, the material data and the production process data of the product are substituted into the production BOM generation module to obtain an automatically generated product BOM solution corresponding to it, and then the product information and the product BOM solution corresponding to the product information are stored in the product BOM database of the material platform, so that when the operator places an order on the material platform according to the product name, the product BOM solution corresponding to the product name is automatically called for the production and supply of the corresponding products, which reduces the workload of engineers in issuing product BOM solutions, shortens the generation time of product BOM solutions, improves work efficiency and improves the accuracy of product BOM, and effectively avoids human errors in the process of engineers issuing product BOMs; avoids the technical problem that the production BOM in the prior art is mostly maintained manually by engineers, which is not only inefficient, but also has a high error rate, resulting in production material preparation errors and serious delays in production delivery.

[0137] It should be pointed out that although the various steps in the above embodiments are described in a specific order, those skilled in the art can understand that in order to achieve the effects of the present invention, different steps do not have to be performed in such an order. They can be performed simultaneously (in parallel) or in other orders. These changes are within the scope of protection of the present invention.

[0138] The step division of the above methods is only for clear description. When implemented, they can be combined into one step or some steps can be split and decomposed into multiple steps. As long as they include the same logical relationship, they are all within the protection scope of this application; adding insignificant modifications to the algorithm or process or introducing insignificant designs without changing the core design of the algorithm and process are all within the protection scope of this patent.
