Fig. 1 is the flow diagram of one embodiment of bill of materials extracting method according to the present invention, as shown in Figure 1:
Step 101, the product material information in bill of materials is obtained, product feature expression is obtained from product material information
Formula.
Material inventory list can be super BOM table, and comprising the product material information by multiple projects, project can drive for two
Automobile, 4 wheel driven automobile, electric car etc..Product material information can be with the row information in material inventory list.For each product
Product feature expression formula is all arranged in material information, and product feature expression formula is the logical expression being made of product feature and operator
Formula.Operator in logical expression includes logic or logical AND, logic NOT etc., and product feature expression formula includes logic or patrols
Volume with the relationships such as, logic NOT, for expressing influence of the product feature to product.
Product feature can use the form of feature code, and product feature can be from a variety of dimensions of product function to product
Description is made, a variety of dimensions include the dimensions such as function, material, structure.One product might have multiple product features, i.e., for
One product may be correspondingly arranged on multiple feature codes.Product material information in bill of materials is as shown in table 1 below:
Table 1- material inventory list
The product material information of one product of each behavior of material inventory list.For example, the first behavior of material inventory list
The product material information of driving motor afterwards, the product feature expression formula of rear driving motor are AMRB&&ATRB.AMRB and ATRB are
The feature code of two product features of driving motor afterwards, product feature expression formula AMRB&&ATRB by the two feature codes and
Logic and operation symbol is composed.
Step 102, it is matched, is obtained corresponding with this product feature with product feature based on product feature matching set
Matching result.
Step 103, the logical operation value of product feature expression formula is calculated according to matching result.
Step 104, logic-based operation values extract product material information from bill of materials.
In one embodiment, product material information can be a BOM row in BOM table, traverse all in BOM table
Row, parsing have the BOM row (product material information) of feature expression and match user option, finally determine corresponding BOM row
Whether it is easily selected by a user, obtains the BOM row selected, user is returned in the form of inventory, obtains the BOM for unitem.
If it is determined that mistake occurs in the BOM of the unitem for obtaining, engineer can verify super BOM with the BOM of this unitem
In product feature expression formula configuration correctness.
Fig. 2 is the flow diagram of another embodiment of bill of materials extracting method according to the present invention, such as Fig. 2 institute
Show:
Step 201, product feature expression formula is parsed, obtains at least one product feature.
Parsing to product feature expression formula can be by a variety of method.For example, splitting product using regular expression method
Feature expression, to obtain at least one product feature.
Step 202, determine whether product feature matching set includes product feature, if it is, determine successful match,
If it is not, then determining that it fails to match.
The target product feature of user's selection is obtained, determines that at least one product corresponding with this target product feature is special
Sign generates product feature matching set according at least one product feature.
Step 203, if it is determined that product feature successful match then sets matching result value corresponding with this product feature
It is set to true；If it is determined that product feature matching is unsuccessful, then set matching result value corresponding with this product feature to
false。
Step 204, each product feature in product feature expression formula is replaced with corresponding with this product feature
Matching result value.
Step 205, logical operation is carried out to product feature expression formula and obtains logic corresponding with this product feature expression formula
Operation values.
Step 206, logic-based operation values extract product material information from bill of materials.
Such as, if it is determined that the corresponding logical operation value of product feature expression formula is true, then extracts and this product feature
The corresponding product material information of expression formula.It can generate and be produced with the target of user's selection based on the product material information of extraction
The corresponding target signature bill of materials of product feature.
In one embodiment, user needs to extract bill of materials related with a project, and the target of user's selection produces
Product feature is " four-wheel drive ", determining five product features " AMFB " corresponding with this target product feature " four-wheel drive ",
" ATFB ", " AMRB ", " ATRB ", " ADMA " generate product feature matching set product feature matching according to five product features
Gather { AMFB, ATFB, AMRB, ATRB, ADMA }.
When carrying out the parsing of product feature expression formula, using regular expression method by product feature expression formula to be resolved
It is split so that at least one product feature must be obtained.Regular expressions method is also known as normal representation method, conventional expressing method (Regular
Expression, regular expressions method is described using single string, matches and a series of meet some syntactic rule in code
Character string.
The corresponding matching value of each product feature in product feature expression formula can be both configured to false.The above table 1
In bill of materials in rear-guard motor and postposition retarder (two drive) product material information for be illustrated: obtain rear-guard
The product feature expression formula of dynamic motor is AMRB&&ATRB, and the product feature expression formula of postposition retarder (two drive) is AMRB&&
ATRB&&ADMR.The two product feature expression formulas are parsed using regular expressions method, the product of driving motor after acquisition
Feature is AMRB and ATRB, and the product feature of postposition retarder (two drive) is AMRB, ATRB, ADMR.
Determining that product feature matching is gathered includes the production of rear driving motor in { AMFB, ATFB, AMRB, ATRB, ADMA }
Matching result value corresponding with AMRB and ATRB is then both configured to true by product feature AMRB and ATRB.By rear driving motor
Each product feature in product feature expression formula AMRB&&ATRB replaces with matching result value, then the product of rear driving motor
Feature expression is true&&true, after carrying out logical operation, corresponding to the product feature expression formula with hereafter driving motor
Logical operation value be true.
Determine that in product feature matching set { AMFB, ATFB, AMRB, ATRB, ADMA } include postposition retarder (two
Drive) product feature AMRB and ATRB, then matching result value corresponding with AMRB and ATRB is both configured to true, determines product
Characteristic matching set { AMFB, ATFB, AMRB, ATRB, ADMA } does not include the product feature ADMR of postposition retarder (two drive), then
False is set by matching result value corresponding with AMRB.By the product feature expression formula AMRB&& of postposition retarder (two drive)
Each product feature in ATRB&&ADMR replaces with matching result value, then the product feature expression of postposition retarder (two drive)
Formula is true&&true&&false, the product feature expression formula institute after carrying out logical operation, with this postposition retarder (two drive)
Corresponding logical operation value is false.
Since the corresponding logical operation value of the product feature expression formula of rear driving motor is true, then driving motor after extracting
Product material information, since the corresponding logical operation value of product feature expression formula of postposition retarder (two drive) is false, then
It is unselected.
