Bill of material and requirements calculation systems

The Bill of Material and Requirements Calculation System to be presented comprises the first phase of a total part number data base development that is expected to encompass all areas of production and inventory control within the McDonnell Aircraft Company component of McDonnell Douglas Corporation.

The system develops a bill of material file that contains both an engineering product configuration and a manufacturing product configuration. The file is created and maintained using both on-line real time and batch data entry methods. Included in the applications processed against the bill of material are programs which: perform a configuration audit to insure that the engineering and manufacturing configurations agree; calculate requirements for all manufactured parts; perform bill of material breakdowns and generate product structure listings; and perform document follow-up and status reporting in manufacturing operational areas.

The data base has been developed using the data management and teleprocessing facilities provided by the Information Management System (IMS). On-line update and retrieval is accomplished via a network of cathode ray tubes, on-line typewriters and on-line medium speed line printers located in operational areas.
