Description
Technical Field
The invention belongs to the technical field of machinery, and particularly relates to a product electronic album construction method based on neutral BOM.
Background
Neutral BOMs have their unique advantages in the face of user demand:
1. compared with the EBOM, the neutral BOM mainly considers the structure of the product and the parts for the convenience of understanding of users, and focuses on embodying the functions of the product and the parts.
2. The neutral BOMs contain different numbers of parts: in a neutral BOM, the product typically contains fewer parts than the EBOM at the design stage. Designing the BOM requires that products on the top layer are expanded step by step according to membership of parts, and each part on the bottom layer is known. The neutral BOM mainly expresses the information of each functional unit from the service perspective, and the structure of the functional units does not need to be expanded and described layer by layer.
Strict membership exists between the upper and lower levels of the EBOM, and the upper and lower levels of the neutral BOM can be logically connected through functional units.
The parts in the EBOM are mainly design and part production process information, and the neutral BOM is mainly an introduction to the functions, performances and positional relationships of the product and the parts that can be understood by the user, and also includes necessary service attributes, such as outsourcing parts, wearing parts, spare parts, and the like.
To sum up, most modeling enterprises directly use the EBOM to make product albums facing the needs of users at present, which cannot completely meet the needs of users, and building product albums based on neutral BOM is a necessary way for building service type enterprises and strategic transformation.
At present, the construction of a neutral BOM for service and maintenance is mature in the aerospace field and is also comprehensively developed in the automobile and engineering machinery industries, but the construction of the neutral BOM is low in efficiency when the neutral BOM faces to products with large output, small batch and multiple varieties.
The current neutral BOM construction modes mainly comprise two types:
one is model-driven neutral BOM generation. BOM construction personnel need to use the three-dimensional model to reassemble to generate a new model, and then the neutral BOM of a certain example is formed by using the upper-lower hierarchical relation of the model; this method is extremely inefficient in terms of construction efficiency, requires a lot of assembly work for the model by the fabricator, and has high requirements for the worker.
Another method is to first establish BOMs of all materials of the example in a design system such as PDM, and then manually adjust the structural hierarchy of the materials by constructors to establish a neutral BOM of the example. This method enables batch creation when creating service views of materials, but also consumes a lot of manpower when dealing with structural adjustments.
In addition, the two methods cannot be flexibly converted when facing products with multiple configurations and multiple instances, and particularly when facing different instances, BOMs need to be repeatedly constructed every time instance generation is carried out, so that the workload is large, the efficiency is low, and the accuracy is poor.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provide a product electronic album construction method based on neutral BOM, which can utilize the existing EBOM to quickly generate neutral BOM and can utilize a plurality of instances after the neutral BOM is constructed once so as to achieve the purpose of quickly generating the product album.
In order to solve the problems of the prior art, the invention discloses a product electronic atlas construction method based on neutral BOM, which comprises the following steps:
s1, analyzing the EBOM template, and establishing a structure of the BOM template according to the relationship between the upper and lower parent and child items in the EBOM;
s2, comparing the EBOM template with the neutral BOM template, and optimizing the neutral BOM template according to the comparison result to generate an instantiated neutral BOM;
and S3, generating a directory tree and material details of the album by using the instantiated neutral BOM.
Preferably, in step S1, the BOM template is created and the material name of each material item in the EBOM template is also read to form the material name of the node in the template.
As a preferred scheme, in step 1, the following adjustment should be performed on the nodes in the BOM template:
merging the nodes which are used as the minimum service units and do not need to show the lower level of the minimum service units;
splitting the node which can be used as the minimum service unit after splitting;
and when the service units are recombined based on the service requirements, adding new material nodes.
Preferably, step S2 further includes the following steps:
s21, comparing the structures according to the BOM template to generate a new structure;
s22, endowing the set service attribute in the template to the instantiated neutral BOM;
and S23, adding new material information corresponding to the material nodes which do not exist in the original template into the template, and defining service rules and attributes of the new material information.
Preferably, step S21 further includes the following steps:
for a material node which can be used as a minimum service unit, transmitting material coding information in the EBOM to the node, and if a lower level exists, not displaying the structure; for the newly added material nodes when the service units are recombined based on the service requirements, no coding information is generated, but a new structure is formed; and giving new material codes to the material nodes which can be used as the minimum service units after splitting to the next-level splitting nodes to form a new structure.
As a preferred scheme, in step S22, the specific method for assigning the service attribute set in the template to the instantiated neutral BOM is as follows: and analyzing the structure position of the node in the template, comparing the structure position with the material position in the EBOM, and transmitting the information such as the service attribute set in the template, the material code in the EBOM and the like to the node for the materials with the same position and the same name.
The invention has the following beneficial effects: the working efficiency of the atlas engineer can be greatly improved, and the rapid and accurate generation of the atlas is ensured from the working time and the accuracy.

definition of key terms:
neutral BOM template-a tree structure similar to BOM, but the material information of tree nodes only includes material names (hereinafter referred to as template);
neutral BOM-for a certain example product, a bill of materials that describes the service attributes of the complete product and parts, such as consumable parts, spare parts, etc.;
service attribute-material attribute facing service requirement, such as outsourcing part, vulnerable part, etc.
As shown in fig. 1, a method for constructing an electronic album of products based on a neutral BOM mainly includes constructing an example neutral BOM and constructing an example album. The concrete content is as follows:
s1, acquiring an EBOM (e.g., the EBOM shown in FIG. 2), analyzing an EBOM template, and establishing a structure of a BOM template according to the relationship between the upper and lower parent and child items in the EBOM, as shown in FIG. 3; and simultaneously, reading the material name of each material item in the EBOM template to form the material name of the node in the template. When building a BOM template, the nodes in the template need to be adjusted as follows:
as shown in fig. 4, the node which is the minimum service unit and does not need to show its lower level is merged; splitting the node which can be used as the minimum service unit after splitting; and when the service units are recombined based on the service requirements, adding new material nodes.
And after the BOM template is established, setting service attributes of the nodes in the template. Firstly, analyzing the belonged material type by taking the material name as a basis; secondly, when the materials with the same name appear for multiple times in different levels of the tree structure, the method can distinguish the materials according to the positions of the materials, and is convenient for judging the true classification of the material attribution.
And S2, comparing the EBOM template with the neutral BOM template, and optimizing the neutral BOM template according to the comparison result to generate an instantiated neutral BOM. The data comparison mainly comprises three aspects: structure comparison, attribute information inheritance and reverse template supplement.
In the structure comparison process, for a material node which can be used as a minimum service unit, material coding information in the EBOM is transmitted to the node, and if the node is a subordinate node, the structure is not displayed; for the newly added material nodes when the service units are recombined based on the service requirements, no coding information is generated, but a new structure is formed; and giving new material codes to the material nodes which can be used as the minimum service units after being split to form a new structure, as shown in fig. 4.
In the process of inheriting the attribute information, the structure position of the node in the template is analyzed, the structure position is compared with the material position in the EBOM, and for the materials with the same position and the same name, the information such as the service attribute set in the template and the material code in the EBOM is transmitted to the node, as shown in fig. 5.
In the reverse template supplement process, new material information corresponding to material nodes that do not exist in the original template is added to the template, and the definition of service rules and attributes needs to be performed on the new material information, as shown in fig. 6.
S3, using the created instantiation-neutral BOM, automatically converting the structure into chapters and directories in the document content, and automatically converting the information of each node in the structure into material details (including material codes, names, quantities, service attributes, etc.) in the document content, so as to quickly generate an album, as shown in fig. 7.
In the process, the word document is firstly developed for the second time, so that the word document can be automatically written with information (the second development utilizes the existing development interface, and can be directly applied, so that further description is omitted). Reading in the material node hierarchy information of the instantiated neutral BOM, sequentially corresponding to the chapter directories corresponding to the album, and if the BOM total node is the total title of the album document, the BOM primary node is the secondary title of the document, and so on. And simultaneously, reading the next layer material information of the BOM node and filling the next layer material information into the document to be used as a part list of the corresponding title of the node.
By instantiating a neutral BOM and comparing with the previous construction mode, the construction method provided by the application is found to be superior in atlas construction efficiency. The data shown in table 1 are the comparison of the results of the people who constructed the atlas by taking 3 examples of the same series as an example:
TABLE 1 sample product working person day statistics

| Traditional method (human being) | 30 | 30 | 30 |
| The method (Renxian) | 15 | 5 | 5 |
As can be seen from the comparison tests, the method provided by the invention can effectively improve the production efficiency and can well meet the production requirements of users. The neutral BOM can be used for quickly and accurately organizing the product description structure after being constructed, so that the product album can show the product at the angle of a user, the use requirement of the user is met, and the customer satisfaction is improved.
In the invention, the secondary development of the word document utilizes the existing development interface, can be directly applied, is the prior art, and is not further described.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
