In the uniting vertical manufacturing industry, that the list which shows the relationship which you say whether the product from which part subordinate component intermediate product and fund material etc. is constituted & is produced.
With production control systemand "the configurations management function" of MRP and the like it becomes the core database, other than name type type turn quantity of each list of items, information of man-hour and the manufacture sequential standard lead time and related to etc. with part are necessary for production and assembly part is defined.
BOM is divided into summary type and structured type manner of the register (data structure) by. For example to producing end product A, intermediate product B 1 and part C 3 being necessary, we assume that furthermore part C 2 is necessary even in production of that intermediate product B. In this case, as for being necessary to produce product A, "part C 5" and registering summary type, "intermediate product B 1 and part C 3" registers product A, separately intermediate product B "part C 2" those where it registers is structured type.
Depending upon use, M-BOM (the production bill of material), E-BOM (the design bill of material), S-BOM (the sale bill of material) and the like it is. These differ the respective use and the data, but the part which can be standardized on the other hand it is many. By the fact that each BOM is integrated, information of the respective each process will be referred to mutually, the solution that has appearedthenproduct development and product life cycle management probably will be taken a second look in whole.
