Bill of material comparison system and method
First Claim
1. A bill of material (BOM) comparison system for automatically comparing current BOMs with corresponding original BOMs, and recording differences between the BOMs if any change of design occurs, the system comprising:
- a database comprising a changed BOM file for storing BOMs that need to be compared, and an original BOM file for storing corresponding original BOMs that can be compared with the current BOMs; and
a BOM comparison module for comparing contents of the changed BOM file and the original BOM file, and for generating a comparative BOM file.

Abstract
A bill of material (BOM) comparison system includes a database (130) comprising a changed BOM file (1310), an original BOM file (1320) and a comparative BOM file (1330), and a BOM comparison module (1020) for comparing contents of changed BOM files and original BOM files. A BOM comparison method includes the steps of: retrieving a changed BOM file and an original BOM file; generating a changed sub-file according to the changed BOM file; generating an intermediate sub-file according to the original BOM file; comparing information on parts in the changed sub-file with information on parts in the intermediate sub-file; generating a plurality of sub-files to record comparative results; and integrating the sub-files into a comparative BOM file.
