Technical Field

[0001] The present invention belongs to the technical field of MBOM construction, and specifically relates to a method for constructing an MBOM. Background Art

[0002] MBOM is a planning list, a derivative of the indented bill of materials. This list is arranged according to the modules or options of the product. In enterprises where products have multiple optional features, MBOM is usually used for series products. Series products usually consist of three types of materials: common parts, basic components, and optional parts. They cannot be directly copied into a production job list. They need to go through product configuration to form an indented bill of materials before they can be released into the job order.

[0003] At present, MBOM construction is mainly carried out in Windchi ll. The MBOM structures of different professions are quite different, the construction process is relatively complicated, and the standardization of MBOM structures is low, resulting in a low degree of process reuse. The level of process design depends on the level and responsibility of the process engineer, and the process is not closely integrated with the site. On the other hand, the operation of building MBOM in Windchi ll is relatively complicated, and the construction efficiency is difficult to improve. In order to improve the efficiency, level and quality of process design, it is urgent to adopt more advanced MBOM construction methods and tools. Summary of the invention

[0046] Step 4: Maintain the factory view

[0047] Each professional process engineer maintains the factory view information required by the EBOM and the materials applied for by the process in Excel, and submits it to the company's production, procurement, materials, quality, information and other departments to supplement and fill in the relevant business attributes;

[0048] Step 5: Build MBOM

[0049] Each discipline builds MBOM in Windchi ll based on the production rhythm and the supply and demand relationship between materials at all levels;

[0050] Step 6: Prepare process BOP

[0051] Specify personnel qualification requirements, material allocation, working hours, process resources and other information for the corresponding processes and self-made parts;

[0052] Step 7: Create a production version

[0053] In the case where there are multiple BOM structures due to different supplier structures, different MBOM structures are built through multiple BOMs;

[0054] Step 8: Create a bicycle BOM

[0055] For products that require the activation of a single vehicle MBOM, a single vehicle BOM is created for each vehicle of each project after the MBOM and BOP are compiled.

[0056] Body MBOM and BOP: Body MBOM is composed of lower-level sub-components. The first-level sub-components mainly include the roof, chassis, end wall, side wall and the BOP of the components in the body MBOM of the connector; Painting MBOM and BOP: Painting MBOM is composed of lower-level production beat components. Since no materials are put into the beats such as sandblasting, the MBOM only contains the beat 5 bonding process. The BOP of painting is directly maintained in SAP, and the process flow of painting can be seen in SAP; Assembly MBOM and BOP: The components installed in each beat are hung under the materials of each beat, which is consistent with the process under the beat; each level of components has its own BOP, but since the materials have been organized according to the process, each contains only one process; Bogie MBOM and BOP: Bogie MBOM organizes sub-components according to the production beat, and the process materials are hung under each beat, and the framework MBOM organizes materials according to the lower-level assembly sub-components; MBOM-BOP solution business architecture: This business architecture contains two layers: the bottom layer is the supporting activities, which are mainly used to define and maintain the foundation required for MBOM-BOP conversion. data, data templates and workflow templates, etc.; the upper layer is the core business of MBOM-BOP conversion, including activities such as creating MBOM framework, process division, detailed process design and process management; MBOM-BOP solution data model: standard production line, MBOM template and standard BOP belong to standard structure, which are created and maintained by system administrator or specific roles; MBOM instance is created and maintained by process personnel; standard structure data model: standard structure template includes standard production line, MBOM framework template and standard BOP. The workstation under the standard production line is 1:n with MBOM template. A workstation can have one or more MBOM templates. Each node on the MBOM template needs to be associated with the corresponding BOP template. When building MBOM, BOP is automatically brought out for the node; MBOM instance data model: MBOM instance is the main output of process design work. It is automatically generated by the system based on MBOM template and relevant information input by process personnel. Its data model is basically the same as MBOM template; EBOM data model: EBOM is obtained from Windchi through interface ll system, the data structure in this system includes two parts: material information and material relationship; Function and logic design: the functions provided by the system include adding (input: production line number, name; output: adding a record to the list), deleting (input: selected standard production line; output: deleting the selected standard production line from the list; rule: multiple selections and batch deletions are allowed, and templates that have been used cannot be deleted), publishing (input: selected standard production line; output: the status of the production line record in the list is displayed as "published"; rule: multiple selections and batch publishing are allowed, and the published production line cannot be modified. Only the published production line can be selected for use when MBOM is built), and upgrading (input: selected standard production line; output: adding a new version of the production line in the list, the version number is updated synchronously, and the status is "unpublished";Rule: Only "unreleased" production line versions are allowed to be edited and modified), View and edit (input: selected standard production line; output: pop-up window, display standard production line diagram, production line in "unreleased" state can modify its production line diagram; rule: only "unreleased" production line versions are allowed to be edited and modified), Associate MBOM (input: selected workstation, selected MBOM template (pop-up window selection); output: display the associated MBOM template number and name on the corresponding workstation record in the list, click to view the associated MBOM template, and drill down to BOP, equipment resources, etc. layer by layer; rule: a workstation can be associated with multiple MBOM templates). ;

[0057] Among them, Windchi ll in step 3 and step 5 can compile the process flow and set the serial and parallel relationship and sequence between the processes.

[0058] Windchi ll is a set of integrated applications that can be used to manage the entire life cycle of products and processes.

[0059] Among them, the MBOM in step 2, step 5, step 7 and step 8 is divided into three stages during assembly: off-line, pre-assembly and final assembly.

[0060] During the off-line stage, the materials are organized according to different parts of the vehicle, and sub-materials are formed according to the production rhythm in the pre-assembly and general assembly stages.

[0061] Among them, the EBOM in step 4 is imported from Windchi ll or an external file and is read-only in the system and cannot be modified.

[0062] By setting the EBOM to read-only and not allowing modification, data confusion can be prevented when the EBOM is imported and used.

[0063] Among them, the process in step six is ​​formed by each beat and hung up to the work center, and the first process is hung up to put in the materials.

[0064] The details of the process are described in the process document, and only the process time is reflected in the process.

[0065] Among them, the process routes for dividing materials in step one are divided in the Excel file and are not included in the system management.

[0066] By dividing the material process route in an Excel file, each part of the process route can be displayed in more detail and clearly, thereby improving the efficiency of dividing the material process route.

[0067] When applying for material numbers in step three, follow the material coding principles and pay attention to the classification of material codes.

[0068] Each material code corresponds to a unique material. Following the material coding principles can avoid confusion and errors between materials, thereby helping to improve the success rate and efficiency of material number applications, and also help to better manage and control the use of materials.

[0069] The factory view in step 4 displays the project in a hierarchical manner, up to eight levels, to display the logical relationship between units, functions, etc. in the actual factory hierarchy.

[0070] In the factory view, according to the actual process requirements, a flexible factory hierarchy structure can be created just like creating a tree-type folder directory.

[0071] When filling in and submitting the factory view information in step 4, you must follow the relevant precautions. Before submitting the information, check all input data and settings to ensure that there are no omissions or errors.

[0072] Following the precautions for factory view information can ensure the accurate submission of factory view information, thereby better utilizing the factory view for factory management, improving the review pass rate, and reducing unnecessary repeated modification submissions.

[0073] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0074] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
