Based on the same inventive concept, the embodiment of the application also provides a bill of materials generation method, and referring to fig. 2, the summary flow of the bill of materials generation method provided by the embodiment of the application is as follows:

step 201: and receiving externally input product information and incoming material state information, and generating an initial material topology according to the product information and the incoming material state information.

In practical application, the product information refers to unique identification information of a product to be produced, and the product information can be a product name or a product number. The incoming state information is information indicating whether or not a part or a component in each EBOM in the initial material topology is in a factory, wherein the incoming state is a state of the part or the component transferred from a supplier to a factory where a product is produced, and the component is generally composed of a combination of parts. The initial material topology is a topology diagram which is preliminarily generated by utilizing a product structure tree pre-stored by a system and represents the corresponding relation among each EBOM, each PBOM and each link in an assembly flow chart according to product information and incoming material state information. Specifically, the initial topology generating unit in the bill of materials generating system receives the product information and the state information and generates an initial bill of materials, which may be, but is not limited to, the following ways:

Firstly, receiving externally input product information and incoming material state information;

secondly, determining a product structure tree according to the product information; adjusting each EBOM in the product structure tree according to the incoming material state information and determining the identification information of the adjusted EBOM;

then, each PBOM is determined according to the adjusted EBOM and the first relation, and each first connection line between the adjusted EBOM and the corresponding PBOM is respectively established; the first relation is a pre-stored corresponding relation between the EBOM and the PBOM;

thirdly, determining an assembly flow chart according to each PBOM and the second relation, and respectively establishing each second connection line between each PBOM and a corresponding link in the assembly flow chart; the second relation is the corresponding relation between the pre-stored PBOM and each link in the assembly flow chart;

and finally, generating an initial material topology according to the adjusted EBOM, the identification information of the adjusted EBOM, each PBOM, the assembly flow chart, each first connecting line and each second connecting line.

In practical application, after receiving the product information and the state information, the initial topology generating unit in the bill of materials generating system can determine a product structure tree of a product in the product information in a plurality of pre-stored product structure trees according to the product name or the product number in the product information, and according to the incoming material state information in the state information, set the identification information of the EBOM in which the incoming material state information is the material in factory to be yes, set the identification information of the EBOM in which the incoming material state information is the material in factory to be no, and adjust the EBOM to set the display color of the EBOM in which the identification information is no in each EBOM to be gray, and not participate in the subsequent determining process of each PBOM and not establish a connecting line. And determining each PBOM according to the adjusted EBOM and the pre-stored corresponding relation between the EBOM and the PBOM, and respectively establishing a first connection between the adjusted EBOM and the PBOM with the corresponding relation. And then, determining each link in the assembly flow chart according to the corresponding relation between each PBOM and the pre-stored PBOM and the assembly flow chart, and respectively establishing a second connection between the PBOM with the corresponding relation and the links in the assembly flow chart. And finally, generating an initial material topology according to the adjusted EBOM, the identification information of the adjusted EBOM, each PBOM, the assembly flow chart, each first connecting line and each second connecting line. Referring to fig. 3, an initial material topology of a product is shown.

Step 202: based on the sequence of each link in the assembly flow chart of the initial material topology, performing position adjustment on the PBOM correspondingly connected with each link in the assembly flow chart; and according to the sequence of the PBOM after the position adjustment, performing position adjustment on the EBOM correspondingly connected with the PBOM after the position adjustment, and updating the initial material topology according to the PBOM after the position adjustment and the EBOM to obtain an intermediate material topology.

In practical application, the sequencing adjustment unit of the bill of materials generating system can adjust the positions of the PBOMs correspondingly connected with each link according to the sequence of each link in the assembly flow chart under the condition that the sequence of each link in the assembly flow chart is kept unchanged after the initial bill of materials is received, so that the sequence of each PBOM corresponds to the sequence of each link in the assembly flow chart. After finishing the sequence adjustment of each PBOM, the sequence of the corresponding connected EBOM is adjusted according to the adjusted sequence of the PBOM. Through the two-time position adjustment, the sequence of each PBOM and each EBOM in the initial material topology corresponds to the execution sequence of the assembly flow chart. Specifically, the ranking adjustment unit in the bill of materials generating system updates the initial topology of materials to obtain the intermediate topology of materials, which may be, but is not limited to, the following ways:

First, ordering each second connection line in the initial material topology based on the sequence of each link in an assembly flow chart of the initial material topology to obtain a first sequence.

And secondly, carrying out position adjustment on the PBOM connected with each second connecting wire in the initial material topology according to the first sequence.

And then, sequencing each first connection in the initial material topology according to the sequence of the PBOM after the position adjustment is completed to obtain a second sequence.

And thirdly, carrying out position adjustment on the EBOM connected with each first connecting wire in the initial material topology according to the second sequence.

And finally, updating the initial material topology according to the PBOM and the EBOM after the position adjustment is completed to obtain an intermediate material topology.

In practical application, fig. 4 is a schematic diagram illustrating that a target material topology is gradually generated from an initial material topology, second connection lines connected to each link may be ordered according to the sequence of each link in an assembly flow chart, and when one link in the assembly flow chart corresponds to a plurality of connection lines, the sequence of the plurality of connection lines connected to the same link may be determined according to the original sequence of the plurality of connection lines. The first connection lines of the PBOM connection can be ordered according to the sequence of the PBOM after the position adjustment is completed, and when the PBOM corresponds to a plurality of connection lines, the sequence of the plurality of connection lines connected with the same PBOM can be determined according to the original sequence of the plurality of connection lines. After the position of the PBOM connected with each second wire in the initial material topology is adjusted according to the first sequence, the position of the EBOM connected with each first wire in the initial material topology is adjusted according to the second sequence, so that the intersections of each first wire can be reduced, the intersections of each second wire can be reduced, the relation among the assembly flow chart, each PBOM and each EBOM can be displayed more concisely and intuitively by the material topology, the arrangement sequence of the EBOM and the arrangement sequence of the PBOM can be made to correspond to the assembly execution sequence, a design engineer can conveniently know the assembly flow of a product, the design engineer can conveniently design a product with better manufacturability, the process engineer can conveniently know the product level, the attribute and the like, and the output of a higher-quality process document such as a PFMEA is facilitated.

Step 203: and correspondingly updating the numbers of the PBOM and the EBOM in the intermediate material topology according to the arrangement sequence of the PBOM and the EBOM in the intermediate material topology to obtain a target material topology.

In practical application, after receiving the intermediate material topology, the target topology generating unit of the bill of materials generating system may renumber the PBOM and the EBOM according to the arrangement sequence of the PBOM and the EBOM in the intermediate material topology, so as to obtain the target material topology, and referring to fig. 4, EEXX and PPXX are the renumbered numbers. The method is characterized in that in the process of renumbering the PBOM and the EBOM respectively, the PBOM is numbered according to the arrangement sequence of the PBOM in the intermediate material topology, and the renumbered PBOM with the same original number at different positions is the same; similarly, the EBOM is numbered according to the arrangement sequence of the EBOM in the intermediate material topology, and the EBOM with the same original number at different positions is numbered the same after renumbering. After the renumbering of the PBOM and the EBOM is completed, the method further comprises the step of correspondingly updating the number of the PBOM and the number of the EBOM in the storage unit. The intermediate material topology is a list state of a transition from generating the initial material topology to generating the target material topology. In this way, according to the arrangement sequence of the PBOM and the EBOM in the intermediate material topology, the numbers of the PBOM and the EBOM in the intermediate material topology are correspondingly updated, the material numbers of the EBOM and the PBOM reflect the assembly process of the product, and more meanings are given to the material numbers, so that the method is beneficial for related personnel to initially know the manufacturing flow through the material numbers. In addition, compared with the existing PBOM which is displayed in a tabular mode and corresponds to each link in the assembly flow chart, the corresponding relation among the EBOM, the PBOM and the links in the assembly flow chart can be intuitively displayed through the target material topology, the visual relation is clearly constructed, a design engineer can conveniently know the assembly flow of the product, the design of a product with better manufacturability is facilitated, and on the other hand, the process engineer knows the product level, the attribute and the like, and the process engineer can conveniently output a higher-quality process document.

Further, in order to perform addition of at least one of the EBOM, the PBOM and the links in the assembly flow chart in the initial material topology, the bill of materials generating method further includes:

receiving a first adding instruction input from the outside, and adjusting the topology of the initial material according to the connection relation between the adding target and the adding target in the first adding instruction; the adding target is at least one of EBOM, PBOM and links in the assembly flow chart; the connection relation of the adding targets is the connection object of the adding targets and the first connection line and/or the second connection line of the adding targets.

In practical application, the types of the added targets include EBOM, PBOM and links in the assembly flow chart. And after receiving the first adding instruction and determining the connection relation between the adding target and the adding target, the initial topology generating unit of the bill of material generating system can add the connection relation between the adding target and the adding target into the initial bill of material, and numbers the adding target according to the ordering of the corresponding types after the adding target is correspondingly arranged in the links of the original EBOM, PBOM or assembly flow chart according to the different types of the adding target. Taking an adding target as a PBOM as an example, the connection relation of the adding target is a link in an assembly flow chart of a first connection, an EBOM (electronic component assembly) connected with the first connection, a second connection and a second connection of the PBOM, then an initial topology generating unit adds the link in the assembly flow chart of the PBOM, the first connection, the EBOM connected with the first connection, the second connection and the second connection of the PBOM to an initial material topology, and after the PBOM is arranged at the original last PBOM, the original number of the PBOM is set as the original number +1 of the original last PBOM.
