[0030] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0031] The following description, with reference to the accompanying drawings, outlines a method, apparatus, electronic device, and storage medium for tracing material change history according to embodiments of this application. Addressing the problems mentioned in the background section, this application provides a method for tracing material change history. In this method, the code value of the target material is obtained based on the traceability request, and the change history of the target material is retrieved from the material pool based on the code value. The change history is then identified to obtain the change history of the target material, enabling traceability of the target material's change history. This method can assist in quickly generating a complete bill of materials for a product, assist material management personnel in checking materials, and improve the accuracy of material management. Therefore, it solves the problems in related technologies where material management relies on manual operation for material information entry and other records, leading to increased management difficulty with the increase in the number of materials, low work efficiency, and poor accuracy.

[0032] Specifically, Figure 1 This is a flowchart illustrating a method for tracing material change history provided in an embodiment of this application.

[0033] like Figure 1 As shown, the traceability method for this material change history includes the following steps:

[0034] In step S101, a traceability request for the target material is received.

[0035] It is understood that materials are the basic elements of production. The target materials in this application embodiment can be understood as the designated raw materials used for production on the production line, which may include raw materials, auxiliary materials, accessories, tools, etc. During the production process, raw materials need to be transferred, prepared, mixed, and fed into the production line. This application embodiment can first receive the traceability request of the target materials, and then, based on the traceability request, can assist in quickly generating a complete bill of materials for the product, assist material management personnel in checking materials, and improve work efficiency.

[0036] In step S102, the first code value of the target material is obtained according to the traceability request, and the change history of the target material is obtained from the preset material pool according to the first code value, wherein the change history is generated based on the second code value associated with the first code value in the preset material pool.

[0037] In step S103, the change history of the target material is identified to achieve traceability of the change history of the target material.

[0038] The preset material pool in this embodiment can record the change history of all materials throughout their entire lifecycle within the material pool. Specifically, after receiving a traceability request for a target material, this embodiment can generate an ITEM ID for the target material. This embodiment can effectively trace the material within the material pool using the ITEM ID value. Simultaneously, using EBOM IDn, EBOM IDn+1, EBOM IDn+2, ..., EBOM IDn+m values, the change history of the material throughout its entire lifecycle within the material pool can be recorded, obtaining the feature value set corresponding to a specific stage. The combination of these two methods ultimately achieves rapid traceability of the material's change history. This ensures the accuracy and precision of the traceability information, further improving work efficiency.

[0039] In one embodiment of this application, the change history is generated based on a second code value associated with a first code value in a preset material pool, including: associating the first code value with the second code value of the target material in the preset material pool; when any feature change in the feature set of the target material is detected, updating the initial second code value to obtain a new second code value, and associating the new second code value with the first code value; and generating a change history based on the initial second code value and all new second code values.

[0040] Specifically, taking the material management of complete vehicle parts in the automotive industry as an example; a certain vehicle model uses hexagonal flange bolts to assemble the headlight assembly onto the body-in-white assembly. When this bolt enters the material pool of this vehicle model, the system automatically assigns an ITEM ID to the bolt and generates an EBOM IDn based on the bolt's corresponding feature value set. When the number of bolts changes from 3 to 2, a new second code value, EBOM IDn+1, is generated. Through EBOM IDn, EBOM IDn+1, EBOM IDn+2, ..., EBOM IDn+m, the change history of the material throughout its entire lifecycle within the EBOM target pool can be recorded. EBOM IDn+2 is the new second code value of EBOM IDn+1.

[0041] In one embodiment of this application, after associating the new second encoded value with the first encoded value, the method further includes: associating the new second encoded value with the changed feature value set, and replacing the second encoded value with the new second encoded value.

[0042] Specifically, after obtaining a new second encoding value based on the above embodiments and associating the new second encoding value with the first encoding value, the embodiments of this application can associate EBOM IDn+1 with the modified feature value set; at the same time, EBOM IDn+1 replaces EBOM IDn, and EBOM IDn+1 is associated with ITEM ID.

[0043] In one embodiment of this application, before replacing the second encoding value with the new second encoding value, the method further includes: detecting whether any feature value in the feature value set is the same as its changed feature value; if any feature value is the same as its changed feature value, then generating a preset alarm prompt.

[0044] It is understood that changes to at least one feature value within the feature value set corresponding to the ITEM ID in this application embodiment include both feature value increases and feature value decreases. Taking the material management of complete vehicle parts in the automotive industry as an example, when materials with the same feature value set exist in the target pool, such as left front headlight assemblies with the same material number, quantity, and applicable vehicle configuration, an alarm message will be generated. The alarm prompt can be specifically set according to the actual situation, such as a beeping sound or voice reminder; however, no specific limitation is made.

[0045] As another possible implementation, an alarm message is generated if at least one feature value in the feature value set changes, and the generated EBOMIDn+1 is the same as any EBOM IDn in the EBOM target pool. For example, in the material pool, if the number of hexagonal flange bolts changes from 2 to 2, and other feature values ​​remain unchanged, an alarm message is generated if the generated EBOM IDn+1 corresponding to this ITEM ID is the same as EBOMIDn.

[0046] In one embodiment of this application, before replacing the second code value with the new second code value, the method further includes: detecting whether there is any second code value associated with the first code value in the preset material pool; if there is any second code value associated with the first code value in the preset material pool, then replacing the second code value with the new second code value; otherwise, generating a material addition prompt.

[0047] It is understood that, in this embodiment of the application, the need to update or add a target material can be determined by any second code value associated with the first code value in the material pool. If such an operation exists, the second code value can be replaced with a new second code value to update the target material, ensuring the accuracy and precision of the traceability information. If such an operation does not exist, an alarm message will be generated, and a prompt will be made to add the material.

[0048] For example, in the automotive industry's whole vehicle parts material management, if a certain model's EBOM target pool does not contain the ITEM ID and EBOMIDn of hexagonal flange bolts, and if a new enlarged series of hexagonal flange bolts is added, and it is desired to record that the enlarged series of hexagonal flange bolts is a change from the hexagonal flange bolts, an alarm message will be generated, and the operation of adding materials can be performed to facilitate subsequent management.

[0049] Furthermore, when adding materials to the material pool, this embodiment of the application can define all the characteristic values ​​of the materials according to the business rules to form a characteristic value set. At this time, an ITEM ID is generated, and an EBOM IDn is generated at the same time. This ID is associated with the characteristic set of the material. If a material with the same characteristic value set already exists in the material pool, an alarm message is generated.

[0050] In one embodiment of this application, after updating the initial second coding value and obtaining a new second coding value when any feature change in the feature set of the target material is detected, the method further includes: when the target material in the preset material pool becomes effective again after being invalidated, obtaining the first coding value of the target material corresponding to the updated second coding value, and obtaining the second coding value associated with the first coding value in the preset material pool; when the second coding value becomes effective and there is an updated feature set in the feature value set associated with the second coding value, replacing the updated feature value set associated with the updated second coding value with the feature value set associated with the second coding value; when the second coding value becomes effective and there are multiple updated feature sets in the feature value set associated with the second coding value, obtaining the updated feature set corresponding to the last updated second coding value, and replacing the updated feature set corresponding to the last updated second coding value with the feature value set associated with the second coding value.

[0051] Specifically, when the replaced EBOM IDn in the EBOM target pool needs to be reactivated, obtain the ITEM ID corresponding to EBOM IDn+1;

[0052] Obtain the EBOM IDn associated with the ITEM ID in the EBOM target pool. When EBOM IDn is effective, the feature set corresponding to EBOM IDn replaces the feature set of EBOM IDn+1, and the feature set corresponding to EBOM IDn is marked as EBOM IDn+1, and EBOM IDn+1 is marked as EBOM Dn+1-1.

[0053] Obtain the EBOM IDn associated with the ITEM ID in the EBOM target pool. When EBOM IDn is effective and the ITEM ID is associated with EBOM IDn+m in the material pool, where m≥2, obtain the feature value set corresponding to EBOM IDn+m. If the feature value set corresponding to EBOM IDn+m is the same as the unchanged feature value set, replace the feature value set of EBOM IDn+m with the feature value set of EBOM IDn, and mark EBOM IDn+m as EBOM IDn+m-1.

[0054] Taking the hexagonal flange bolt as an example, when the material fails and needs to be reactivated, first obtain the ITEM ID corresponding to the material failure EBOM IDn+1, and then write all the feature value sets of the bolt corresponding to EBOM IDn+1 according to the EBOM ID associated with the ITEM ID in the EBOM target pool.

[0055] In one embodiment of this application, before associating the first encoded value with the second encoded value of the target material in a preset material pool, the method includes: extracting a third encoded value generated when any material is associated with the preset material pool; matching the feature value set of any material according to the third encoded value, and extracting a type subset within the feature value set; capturing a type subset with the same material type, and generating a preset material pool.

[0056] It is understood that the embodiments of this application can extract the feature value set within the EBOM associated generation EBOM IDn, and extract the type subset within the feature value set; the EBOM IDn corresponding to the same type subset is captured to form a material pool.

[0057] Taking the material management of complete vehicle parts in the automotive industry as an example, all materials required for a vehicle model are defined, such as fasteners, sheet metal parts, interior parts, exterior parts, and electronic and electrical components. At this time, ITEM ID is generated, and EBOM IDn is generated at the same time, ultimately forming a complete material target pool for the vehicle model.

[0058] The material change history tracing method proposed in this application obtains the code value of the target material based on the traceability request, and retrieves the change history of the target material from the material pool based on the code value. By identifying the change history, the change history of the target material is obtained, thus achieving traceability of the target material's change history. This method can assist in quickly generating a complete bill of materials for a product, assist material management personnel in checking materials, and improve the accuracy of material management. Therefore, it solves the problems in related technologies where material management relies on manual operation for material information entry and other records, leading to increased management difficulty with the increase in the number of materials, low work efficiency, and poor accuracy.

[0059] The material change history tracing method of this application embodiment will be described in detail below through specific examples, such as... Figure 2 As shown, it includes the following steps:

[0060] (1) Generate an ITEM ID and associate it with an EBOM to generate an EBOM IDn, where n≥1; if at least one feature value in the feature value set corresponding to the ITEM ID changes, generate an EBOM IDn+1 and associate the EBOM IDn+1 with the modified feature value set; replace the EBOM IDn with the EBOM IDn and associate the EBOM IDn+1 with the ITEM ID.

[0061] (2) Extract the feature set within the EBOM associated EBOM IDn, and extract the type subset within the feature set; capture the EBOM IDn corresponding to the same type subset to form the EBOM target pool; generate alarm information when the ITEM ID corresponding to EBOM IDn+1 has no associated EBOM IDn in the EBOM target pool.

[0062] (3) If at least one feature value in the feature value set changes, and the generated EBOM IDn+1 is the same as any EBOM IDn in the EBOM target pool, an alarm message is generated.

[0063] Next, referring to the accompanying drawings, a material change history traceability device is described according to an embodiment of this application.

[0067] In one embodiment of this application, the acquisition module 200 includes: a first association unit and a first generation unit.

[0068] The first association unit is used to associate the first code value with the second code value of the target material in the preset material pool; when any feature change in the feature set of the target material is detected, the initial second code value is updated to obtain a new second code value, and the new second code value is associated with the first code value; the first generation unit is used to generate a change history based on the initial second code value and all new second code values.

[0069] In one embodiment of this application, the apparatus 10 further includes: a second association unit, configured to associate the new second encoding value with the changed feature value set after associating the new second encoding value with the first encoding value, and replace the second encoding value with the new second encoding value.

[0071] In one embodiment of this application, the apparatus 10 further includes: a second generation unit, configured to detect whether any feature value in the feature value set is the same as its changed feature value before replacing the second code value with a new second code value; if any feature value is the same as its changed feature value, then generate a preset alarm prompt.

[0072] In one embodiment of this application, the apparatus 10 further includes: a third generation unit, configured to: extract a third code value generated when any material is associated with the preset material pool before associating the first code value with the second code value of the target material in the preset material pool; match the feature value set of any material according to the third code value, and extract a type subset within the feature value set; capture the type subset with the same material type, and generate the preset material pool.

[0074] It should be noted that the explanation of the aforementioned method embodiment for tracing the material change history also applies to the material change history tracing device of this embodiment, and will not be repeated here.

[0075] The material change history traceability device proposed in this application obtains the code value of the target material based on the traceability request of the target material, and retrieves the change history of the target material from the material pool based on the code value. By identifying the change history, the device obtains the change history of the target material, thus achieving traceability of the target material's change history.

Therefore, it solves the problems in related technologies where material management relies on manual operation for material information entry and other records, leading to increased management difficulty with the increase in the number of materials, low work efficiency, and poor accuracy.
