[0048] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are 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.

[0049] In the automotive industry, FMEA is often used as a tool for product design and process manufacturing technology risk analysis. As the seven-step FMEA analysis method is applied more and more widely in the industry, software has gradually replaced the traditional FMEA table analysis. However, both the traditional form-filling analysis and the FMEA software currently on the market lack efficient management of product family FMEA. To solve this problem, family DFMEA applications and family PFMEA applications have emerged. In the process of project development, the design of a specific product must undergo DFMEA analysis. In order to conduct DFMEA analysis efficiently, it is necessary to borrow part of the DFMEA of a similar product as the content of the DFMEA analysis of a new product. The current DFMEA software analysis tool can only solve the problem of borrowing the content of a similar product DFMEA. When the content to be borrowed comes from 2 or more products, and there is a version change in the content of the product, how can other products also automatically change these contents? Based on this, the present application provides an FMEA method based on product family management to improve or solve the above problems.

[0050] First embodiment

[0051] In one embodiment, Figure 1 is a flow chart of a FMEA method based on product family management provided according to an embodiment of the present application, Figure 2 FIG. 1 is a flowchart of a FMEA method based on product family management in an embodiment, and the method is applied to a server as an example for explanation. Figure 1 and Figure 2 As shown, the method comprises the following steps:

[0052] S101, creating a family failure mode and effects analysis FMEA, and obtaining analysis items of the first product of the FMEA.

[0053] Specifically, for example, the user clicks "Create DFMEA" and selects "Family FMEA". The user manually creates a family FMEA and enters the basic information page of the family FMEA. In the basic information of the family FMEA, fill in the corresponding required items and click the "Add Project" button in "Basic Information". Click the "Add Project" button in "Basic Information". In the pop-up box, you can select the name of the existing project or the name of the new project A. Click OK, and an instance FMEA project A will be added to the family FMEA.

[0054] S102, editing the structure tree of the first product, and obtaining and publishing the FMEA report of the first product.

[0055] Specifically, for example, through the operation commands of the command loop, the structural analysis, failure function analysis, failure analysis, risk analysis, adding optimization measures and other operations are completed according to the "seven-step method" of FMEA, and the corresponding report is published or saved on the DFMEA report page.

[0056] S103, when adding analysis items of a second product under the same family FMEA, synchronizing the deleted contents of the first product on the structure tree of the second product, and acquiring and publishing the FMEA report of the second product.

[0057] Specifically, for example, when adding an analysis project for a second product under the same family FMEA, click "Edit" on the family FMEA basic information page, click "Add Project", and create a new project DFMEA for product B; manually switch the view in the structure tree to the structure tree for project B, and the system automatically synchronizes the FMEA content of project A and displays it on the structure tree for project B.

[0058] S104, when adding analysis items of a third product under the same family FMEA, synchronize the deleted content of the first product and the difference content of the second product on the structure tree of the third product, and obtain and publish the FMEA report of the third product.

[0059] Specifically, for example, the user manually performs structural analysis, functional analysis, failure analysis, risk analysis, and optimization on Project B and then clicks to publish. On the basic information page of Family FMEA, the user clicks "Edit" and a button for adding a new project appears. After the user clicks the Add Project button, a list of new or selected projects appears in a pop-up window. The user can select existing projects in the software or create a new project C. After selecting or creating a new project, click Confirm, and Family FMEA will have one more project C. The new project C combines the contents of Project A and Project B, and the contents of A and B are displayed on the structure tree view of Project C at the same time.

[0060] Furthermore, the content from other FMEAs is grayed out, and after the content of other FMEAs is updated, it will turn into a yellow frame on the structure tree. New content will be marked with a green icon, red for deletion, and blue for blue content. The person in charge of product B can manually click on these dots to choose whether to synchronize. Click "Synchronize" to agree, and the modified content in B will be automatically synchronized. The system automatically aggregates all content, and users can manually switch the view to all to display all content in project A / B / C on the structure tree.

[0061] The above-mentioned FMEA method based on product family management creates a family failure mode and effects analysis FMEA, and obtains the analysis project of the first product of the FMEA; edits the structure tree of the first product, and obtains and publishes the FMEA report of the first product; when the analysis project of the second product is added under the same family FMEA, the content of the first product is synchronized on the structure tree of the second product, and the FMEA report of the second product is obtained and published. The FMEA method based on product family management of the present application can automatically change the technical problem of the content of other products when there is a version change in the content of a certain product. It realizes the superimposed display of similar FMEAs but different FMEAs on the same page, and only needs to edit and maintain the content of the FMEA of a certain product, and the content will be synchronized to other products in other product families. It also realizes the independent addition and editing of content of a certain FMEA. At the same time, when the content of a certain FMEA changes, it also realizes that the person in charge of other FMEAs is informed.

[0062] Based on the above embodiment, step S102 "obtaining and publishing the FMEA report of the first product" is decomposed and refined, such as Figure 3 As shown, it specifically includes the following steps:

[0063] S201, edit the structure tree of the first product and obtain the FMEA report of the first product.

[0064] S202, release a specific version of the FMEA report.

[0065] It can be understood that this embodiment provides a possible implementation method for obtaining and publishing the FMEA report of the first product, and the method is simple and easy to operate.

[0066] Based on the above embodiment, the process of "synchronizing the deleted content of the first product and the different content of the first product on the structure tree of the second product" in step S103 is decomposed and refined, as follows: Figure 4 As shown, it specifically includes the following steps:

[0067] S301, deleting the synchronized content of the first product on the structure tree of the second product.

[0068] Furthermore, after synchronizing the content of the first product on the structure tree of the second product, the first product may be informed of the content added by the second product.

[0069] S302: on the basis of deleting the synchronized content of the first product on the structure tree of the second product, adding the content of the second product different from the first product on the structure tree of the second product.

[0070] It can be understood that this embodiment provides a possible implementation method for synchronizing the content of the first product on the structure tree of the second product, and the method is simple and easy to operate.

[0071] Based on the above embodiment, the process of "synchronizing the deleted content of the first product and the different content of the second product on the structure tree of the third product" in step S104 is decomposed and refined as follows: Figure 5 As shown, it specifically includes the following steps:

[0072] S401, deleting the synchronized content of the first product on the structure tree of the third product.

[0073] Furthermore, after synchronizing the content of the first product on the structure tree of the third product, the first product may be informed of the content added by the third product.

[0074] S402: adding the difference content of the third product from the second product to the structure tree of the second product on the basis of deleting the synchronized content of the first product on the structure tree of the third product.

[0075] It can be understood that this embodiment provides a possible implementation method for synchronizing the content of the first product on the structure tree of the third product, and the method is simple and easy to operate.

[0076] The step division of the above methods is only for the purpose of 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 scope of protection of this patent; 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 scope of protection of this patent.
