Description

Neutral BOM construction method and system based on process BOM and manufacturing BOM {NEUTRAL BOM BUILDING METHOD AND SYSTEM OF PROCESS AND BASED ON BILL OF MATERIALS}

The present invention relates to the fields of Product Lifecycle Management (PLM) and Product Data Management (PDM), and more particularly, to a method and system for constructing a neutral BOM based on process and manufacturing bill of materials. .

The description in this section merely provides background related to the present invention, and does not necessarily constitute prior art.

After product design and manufacturing are completed, long-term maintenance services are required to fully or partially restore the use value of the product in the operation and maintenance process and extend the life of the product. Therefore, the maintenance service of a product has an important value in terms of the product lifecycle, and for complex products, the maintenance service level directly determines the product market.

Maintenance data management in maintenance services relies on the maintenance BOM. A neutral BOM is the data base of a maintenance BOM used to organize and manage location-independent product data, maintenance materials and knowledge, a common structure and attributes of one model or batch of products with the same structure and organization. Since the neutral BOM is the source of product data in the entire product operation and maintenance process, the construction of the neutral BOM is the basic task of product operation and maintenance management, and the data of the neutral BOM is derived from the physical product or EBOM, PBOM and MBOM.

When operations and maintenance companies do not have product design and R&D data, they often build a neutral BOM based on their perception of the product and related technical data of the physical product. Product-related data that can be obtained by product operation and maintenance companies is mainly random data after product sales, including basic data such as shipping specifications, user manuals, and maintenance manuals. Complex products custom-designed or custom-made by companies, such as ships, airplanes, and rail transportation, and data provided by manufacturers to customers and operations and maintenance companies are also data that manufacturers consider necessary for operation and maintenance, and certain data simplification for this. Disposal is performed to ensure that key technologies are not leaked. A neutral BOM built on these data has problems: the product structure is not perfect, there is no design and manufacturing data, and the managed data and knowledge are relatively simple and cannot support the complex operation and maintenance task requirements.

The product manufacturer is responsible for operation and maintenance and builds a neutral BOM based on EBOM, PBOM or MBOM.

The neutral BOM built on the basis of EBOM manages operation and maintenance data with the product function structure as the core that describes the overall function and structure of the product, but efficiently supports the disassembly and assembly work of some parts and the procurement and manufacturing of spare parts can not do.

A neutral BOM based on PBOM or MBOM takes the product process structure as the core, manages operation and maintenance data, and helps guide the disassembly and assembly operations of operation and maintenance by describing the assembly relationships of the product. However, the overall organization cannot clearly and systematically describe the system and functional structure of the product for the cabin or primary and secondary parts of the process, and is insufficient to support product modification and maintenance of the overhaul layer.

Example 1

This embodiment provides a neutral BOM construction method based on process and manufacturing bill of materials.

As shown in FIG. 4 , the neutral BOM construction method based on process and bill of materials includes the following steps.

S101: Establish a root node for the target product. The root node is a target product node.

S102: Obtain a structure item or system item from the process bill of materials of the target product and use it as a child node or grandchild node of the target product node.

Step 103: Based on the acquired structure items or system items, the upper layer structure of the neutral bill of materials is built using the corresponding hierarchical relationship in the process bill of materials.

S: Obtain total life management parts, fragile parts, and/or exclusive parts from the process bill of materials, acquire members or parts whose properties must be maintained from the manufacturing bill of materials, and obtain the hierarchy of members or parts in the manufacturing bill of materials. Depending on the relationship, it builds a neutral bill-of-materials sub-layer.

S105: Based on the manufacturing bill of materials, add mountable parts to the neutral bill of materials and expand supplier parts to complete the construction of the structure of the neutral bill of materials.

Furthermore, the method further includes the following steps.

S106: Obtain component basic attributes, technical parameters and/or product function descriptions from the process bill of materials, obtain manufacturing part technical parameters from the manufacturing bill of materials, and add relevant information to the neutral bill of materials. Complete the building of a full neutral bill of materials by adding product failure conditions and causes, maintenance descriptions, use instructions, maintenance instructions, and recall statements.

Furthermore, the step S102 of obtaining a structure item or system item from the process bill of materials of the target product and using it as a child node or grandchild node of the target product node includes the following steps in detail.

S1021: Start performing traversing from the process bill of materials root node of the target product.

S1022: Traversing grandchild nodes under the process bill of materials root node, it is determined whether the current child node is a structure item or a system item. In the case of a structure item or a system item, a corresponding child node is selected and step S1023 is entered. Otherwise, the parent node of the current child node is returned.

S1023: Traverse untraversed grandchild nodes under the selected child node to determine whether the current grandchild node is a structure item or a system item. In the case of a structure item or a system item, the corresponding grandchild node is selected and step S1024 is entered. Otherwise, the parent node of the current grandchild node is returned.

S1024: It is determined whether all grandchild nodes under the current child node have been traversed, and if all grandchild nodes of the corresponding node have been traversed, it returns to the parent node of the current child node, otherwise it returns to step S1023.

S1025: It is judged whether all child nodes under the process bill of materials root node have been traversed, and if traversing of all child nodes of the process bill of materials root node has been completed, the process ends, otherwise return to step S1022.

Here, it is a structural item if it is a cabin or a structural component, and a system or child system if it is software and hardware or a combination of hardware and software.

Illustratively, the structural items are, for example, cabins of airplanes and ships, and the system items are, for example, avionics systems, navigation systems and their child systems.

Furthermore, the step S103 of constructing the upper layer structure of the neutral bill of materials by using the corresponding hierarchical relationship in the process bill of materials based on the acquired structure item or system item includes the following steps in detail.

S1031: Traverse child nodes of the process bill of materials root node in the process bill of materials to determine whether the current child node is a structure item or a system item. If it is a system item or a structure item, the corresponding system item or structure item in the neutral bill of materials is related as a child node of the neutral bill of materials root node, and step S1032 is entered. Otherwise, it returns to the parent node of the current child node.

S1032: Traversing the grandchild node of the current child node in the process bill of materials to determine whether the current grandchild node is a structure item or a system item. If it is a structure item or a system item, the corresponding system item or structure item in the neutral bill of materials is associated with the child node of the neutral bill of materials child node, and step S1033 is entered. Otherwise, it returns to the parent node of the current grandchild node.

S1033: It is determined whether all grandchild nodes under the current child node have been traversed, and if all grandchild nodes of the corresponding node have been traversed, the parent node is returned. Otherwise, the process returns to step S1032.

S1034: It is determined whether all child nodes under the process bill of materials root node have been traversed, and if traversing of all child nodes of the process bill of materials root node has been completed, the process is terminated, otherwise the process returns to step S1031.

Furthermore, the above step S104 of obtaining total life management parts, fragile parts and/or exclusive parts from the process materials list, and obtaining members or parts to be maintained from the manufacturing materials list specifically includes the following steps.

Traversing of each child node starts from the root node in the process bill of materials. If the child node is not a system item or a structure item but a total life management part, a fragile part, or a dedicated part, the child node is added to the neutral bill of materials lower layer node set.

Each child node traversing is started from the root node in the bill of materials, and if the child node is not a system item or a structure item and is a member or part that is not in a lower layer node set and needs to be maintained, the child node is also a lower layer node set. add to

Furthermore, the step S104 of constructing a neutral bill of materials lower layer structure according to the hierarchical relationship of members or components in the bill of materials for manufacturing includes the following steps in detail.

In the neutral bill of materials (which already contains the system item and the structure item), starting from the root node, depth-first traversing is performed to build the neutral bill of materials sub-layer.

All child nodes of the current node in the bill of materials are traversed, and for each current child node, if it is not a child node of the corresponding node in the bill of materials and the current child node belongs to the lower node set, the current child node is neutral. It is associated with the grandchild node of the corresponding node in the bill of materials and added to the neutral bill of materials. If not, delete the child node.

If the current node traversed in the bill of materials has no child nodes, it returns to the parent node of the current node in the neutral bill of materials.

Continue until all nodes in the bill of materials have been traversed.

It should be understood that nodes with identical serial numbers and names in process bills of materials, manufacturing bills of materials, and neutral bills of materials are referred to as identical parts and are identical nodes.

What is reflected in the neutral bill of materials is the common knowledge of the product, and the neutral bill of materials information model includes product structure information and attribute information.

Product structure information includes system elements and structural elements of the upper layer and components and parts of the lower layer. The upper layer describes the system function and overall structure of the product, and the lower layer describes the specific disassembly and assembly structure and sequence. The above product structure components all have properties, and reflect the basic properties of the product added in the design and manufacturing stages, as well as technical parameters, function descriptions, failure phenomena and causes, maintenance instructions, use instructions, maintenance instructions, Include a recall description, etc. This is as shown in FIG. 1 .

The so-called basic attributes are: material name, code, unique identification, material level (assembly level, accessory level, part level), material properties (independent parts, dependent parts), and material type (classified according to nature and maintenance type), breakage This means to explain the basic information of the material including whether it is an easy part or a dedicated part.

Technical parameters are reference data for determining the need for maintenance and repair of materials, and are the criteria for review after product failure detection and maintenance.

Functional descriptions are used to describe the function of the material and have reference value for maintenance personnel to perform maintenance work.

The failure phenomenon and cause refer to the failure phenomenon caused by the material damage and the cause of the failure, which is the basis for determining the location of the failure by the service personnel.

Maintenance description means a maintenance description that includes maintenance intervals, maintenance methods and lubrication requirements for the material in use phase.

Instructions for use include installation instructions and debugging instructions, and serve as a basis for service personnel to perform installation and debugging.

Maintenance guidelines include inspection regulations, maintenance regulations, etc., and are the basis for maintenance personnel to perform inspection and maintenance. The recall description includes expected life and material recovery statements, etc., and serves as a basis for disposal of the material or recall after end of life.

Neutral bill of materials data is derived from process bills of materials and manufacturing bills of materials, and is not a conversion of process bills of materials or manufacturing bills of materials data to neutral bills of materials. This is the neutral bill of materials extracting some data from the process bill of materials and the manufacturing bill of materials as needed, as shown in FIG. 2 .

Here, in the extraction process from the process bill of materials to the neutral bill of materials, in the case of system maintenance items and structural maintenance items, maintenance history data, equipment, tools, maintenance work card numbers, process drawings, maintenance process simulation links, etc. Add more maintenance properties like

Systems and structure maintenance items refer to specific systems and structures that require repair or overhaul in maintenance work.

For replaceable maintenance parts, add maintenance attributes such as maintenance history data, spare part number, maintenance work card number, etc.

Interchangeable maintenance part means a specific member or component requiring servicing in maintenance work, but in the form of a replaceable part.

Remove parts that do not require overhaul and delete the corresponding node. Classify easily damaged parts and exclusive parts and perform corresponding treatment.

In the extraction process from Manufacturing Bill of Materials to Neutral Bill of Materials, product structure should be adjusted based on inspection granularity/capability.

Add necessary process paths, assembly technology files, processing/assembly process information, and mounting allowable parts information to parts information.

A fitable part is a part from another supplier that has the same or similar functionality, which extends the supplier part structure.

The mapping relationship between items (products, systems, members, parts, etc., management targets) converted from process bill of materials and manufacturing bill of materials to neutral bill of materials is as shown in FIG. 3 . Here, the borrowing and quoting mapping method is one-to-one or one-to-many, the mountable part is a one-to-many relationship, and the supplier part is a one-to-many relationship.

The present invention builds a neutral bill of materials based on process bill of materials and manufacturing bill of materials data, and the neutral bill of materials not only describes the system and functional structure of the product, but also can describe the detailed disassembly and assembly structure of the bottom layer of parts.

The neutral bill of materials upstream data originates from the process bill of materials, describes the system structure and functional structure of the product from the two perspectives of system and function, and guides the system level modification and overhaul operation of the product.

Neutral bill-of-materials sublayer data originates from manufacturing bills of materials, is oriented to the component level, describes component assembly relationships and assembly relationships within components, and provides technical guidance for routine inspections and small to medium-sized maintenance.
