Description

Method for realizing super BOM data management in product data management system

Technical Field

The invention relates to the technical field of data management, in particular to a method for realizing super BOM data management in a product data management system.

Background

BOM is an abbreviation for Bill of Materials, English, meaning either a Bill of Materials or a component list. The product BOM is a component list of the product, i.e., various component components included in the product. FIG. 1 illustrates a typical product BOM scheme. A hierarchy is the level at which each component of the BOM structure is located. Here, level 1 indicates that it is the root of the BOM, i.e., the product corresponding to the current BOM, and the product ID in fig. 1 is 101. Level 1 consists of level 2, level 2 consists of level 3, and so on. The ID is the ID, i.e. the unique identification code, of the component at each level. BOM usage is the usage of a component on a BOM structure. Typically, the amount of BOM root is 1. The usage of components of other levels is a multiple of the usage of the root, the multiple being equal to or greater than 1. When the customer places an order, the order quantity of the product is n, and the product component stock quantity is the corresponding BOM quantity multiplied by n.

One component of the BOM may come from a different vendor or have multiple versions, for example, a mobile phone may have a memory card that is 8G, 16G, 32G, or 64G. Thus, there may be multiple replaceable components for one component in the BOM. If the components in FIG. 1 with

IDs

301, 203, and 401, respectively, have multiple replaceable components. The existing product BOM solution is to generate a new BOM structure according to each permutation and combination of replacement components, for example, to evolve from product 101 in fig. 1 to product 102 in fig. 2, so that the component with ID 301 is replaced with the component with ID 306, the component with ID 203 is replaced with the component with ID 206, and the component with ID 401 is replaced with the component with ID 403. It is conceivable that with the increase of such combinations, one product will evolve into several or even a huge number of product BOMs.

In addition, the subassembly in the middle of fig. 1 or 2, such as

ID

303, 304, and 502, may itself be organized, with its own BOM structure. The existing solution is to add all the components of this sub-BOM and perform various production stock calculations. Such a BOM structure is exceptionally complex as the number of components in a BOM structure with its own sub-BOM structure increases.

An existing Product Data Management system, Product Data Management, PDM for short, is basically based on the conventional Product BOM scheme shown in fig. 1 or 2. When the PDM generates several BOMs as the number of replaceable components and sub-BOMs increases, there are disadvantages as follows: first, this solution is very inefficient because, with a minor change, a new BOM is mechanically created and is very inflexible; secondly, when a certain component of the BOM structure or the relationship among the components changes, the PDM needs to refresh and adjust all generated BOMs, so that asynchronism is easily caused; third, when the variability of the BOM structure of a product is large, the management of PDM becomes extremely complex. Therefore, the existing BOM scheme is not favorable for modern agile development and rapid product iteration, and an alternative technical scheme is urgently needed.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides a technical solution: a scheme for realizing super BOM data management in a product data management system comprises the following steps:

1) a normal BOM is created, and the normal BOM does not contain any interchange elements and sub BOM structures, as shown in FIG. 1.

2) For the established common BOM, the BOM element with interchange element is marked, all equal interchange elements and unequal interchange elements are listed in parallel under the element, and an identification field is used to respectively mark interchange equality or inequality for all equal interchange elements and unequal interchange elements, as shown in FIG. 4, wherein in the figure, interchange equality or inequality is marked

The representations of (a) are equally interchanged,

indicating unequal interchanges.

3) For the established common BOM, the BOM elements with sub-BOMs are marked, as shown in fig. 5, when an element has a sub-BOM, it is the "root" or "sub-root" in its own self-organizing sub-BOM structure.

4) Both the interchange element and the sub-BOM are embedded into the BOM structure, resulting in a super BOM structure, as shown in FIG. 3. By writing programs and adopting a page interaction technology, free switching among interchangeable elements and free expansion and retraction of the sub BOM are realized. Such a BOM structure contains interchange elements and sub-BOMs. The interchange elements may come from different suppliers, different batches, or different designs. The sub-BOM is self-contained, but can be flexibly added to the BOM structure as a component. Therefore, the BOM is a super-flexible BOM.

One embodiment of the present invention is shown in fig. 3, where the product ID is always constant regardless of how many interchangeable components there are and regardless of how many components there are self-contained BOM structures, e.g., the product is always represented by ID 100 in fig. 3, rather than by

ID

101 and 102 in fig. 1 and 2, respectively, for different product BOMs. Compared with the general BOM technical scheme illustrated in FIGS. 1 and 2, the super BOM scheme implemented by the present invention adds two technical points, namely interchange and sub BOM, to the BOM structure, which are used in the present embodiment respectively

And

and (4) showing. A component having interchangeable labels can have a component that is interchangeable with the component in a BOM configuration. A component with a sub-BOM identifier is only used as a component in the current product BOM, but can be linked to the BOM structure of the component.

Another embodiment of the present invention is shown in fig. 4, where the components are interchanged by identifying the interchanged components. In the BOM structure with

ID

100, 301, 306, 307, 308, 309 are interchangeable. In this embodiment use

Indicate equal interchange, by

Indicating unequal interchanges, 306 and 301 are equal interchanges, 307 and 301 are equal interchanges, 308 are unequal interchanges with 301, 309 are unequal interchanges with 301.

In another embodiment of the present invention, as shown in fig. 5, in the BOM with product ID 100, the component ID 303 carries its own BOM, but this BOM becomes its own system. In the whole BOM structure with ID 100, the sub BOM with ID 303 need not be directly included, but is self-organized.

Specifically, the super BOM structure can be represented in a form of a table, as shown in fig. 3, or in a tree structure based on a graphic block. Also, the symbols of the interchangeable, equal or unequal interchangeable, sub-BOMs may be replaced by other symbols capable of expressing the same meaning. In the data structure, the data field of each component contains an interchangeable tag value, an equal or unequal interchangeable tag value, a self-contained BOM status value, etc.

Specifically, the ID of a component or product may consist of three parts, namely a body ID, an engineering version number, and a scheme number. The model, supplier, lot, etc. information of the component can also be combined with the component ID on this basis to better identify the component.

Specifically, the unit of the BOM usage may be one or more, in which case the BOM usage must be an integer, and the usage of the subordinate component must be an integer multiple of the usage of the superior component. If the units of BOM usage are kilograms or other dimensions, BOM usage may be decimal. The BOM usage of each component can also be set to a stock loss rate or stock loss amount so as to calculate the stock loss of each component in the BOM structure of the product more accurately.

Specifically, in the BOM structure, the mounting position of each component in the entire product can be set.

Specifically, the super BOM scheme can be embedded into a PDM system to replace an original traditional BOM module, and can also be used as an independent functional module by self-organizing.

In particular, the super BOM scheme may be used to manage product development iterations, production stock and procurement stock, as well as Internet-based super BOM management, such as that of the gas distribution Internet.

The working principle is as follows: under the condition that the product ID is not changed, all the interchange changes and the sub BOM associations are cooperatively managed, equal interchange and unequal interchange are flexibly set in the BOM structure of the product, and the sub BOM associations are set.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
