Problems solved by technology

For this reason, an object of the present invention is to propose a method for extracting BOM change data from the change order. The present invention solves the problem of inconsistency between the BOM change result and the content of the change order, and solves the inconsistent filling rules of the change order content, and the inconsistency between the change data and the content of the change order In the case of the situation, change the content classification and itemization, so that the signer can view the process during the signing process, and the archiving staff can check the information

Embodiment 1

[0072] Define the original data that needs to be compared: before (basic) BOM, after (change) BOM;

[0073] For the BOM before the change, through the depth traversal algorithm, recursively traverse the BOM structure, and obtain all the BOM data to be compared.

[0074] The specific operation of defining the collection of stored data is to define the Map collection. Since the material number in the material attribute of the BOM is unique, the [parent number && child level] in the BOM structure can uniquely determine the assembly relationship of the material in a BOM structure, so The composition of the Map collection is Map;

[0075] Until the traversal of the entire BOM structure is completed, a data Map set before modification is formed and recorded as: mapBefore, which stores the structure information and material information of the BOM.

[0076] For the modified BOM, refer to the previous steps to obtain the Map collection of the modified data as: mapAfter.

[0077] Use ...

Abstract

The invention discloses a method for extracting BOM change data from a change list. The method comprises the following steps of S1, defining original data needing to be compared; S2, converting a dataformat, and converting the tree structure into a comparable table structure; S3, performing structure comparison and attribute comparison on the table structure; and S4, persisting a comparison result into a database, and finally performing data entry display and analysis. According to the method, content classification entries are changed, so that signers can check the process conveniently in the signing process, and archives can check information conveniently.

Description

technical field [0001] The invention relates to the technical field of data screening, in particular to a method for extracting BOM change data from a change order. Background technique [0002] Through the analysis of the current status of the BOM change business in aviation manufacturing engineering, at present, the BOM changes and change orders of most units have not formed a data structure, let alone the structure of the BOM change and its change order content. Most of the change order content It is handwritten according to the changes of BOM and drawings. Manual operation will always cause the actual change result of BOM to be inconsistent with the content filled in the change sheet. Once data errors occur, it will have a considerable impact on production. Based on the structure of the change data and the change order, we automatically compare the BOM data before and after the change through the background program, and automatically extract the relevant data of the chan...
