Patent ID: 8190461

Claim:
Software for determining a level of scrap in a business application, the software embodied on non-transitory computer-readable media and comprising computer readable instructions operable when executed to: instantiate a logically centralized master planning business object using production model data for an activity; and calculate requirements for a production planning model using the master planning business object and scrap information, wherein calculating requirements for the production planning model using the master planning business object and scrap information includes: identifying an existence of unassigned scrap levels associated with the activity based on the scrap information, where the scrap information includes at least one of activity scrap, fixed resource scrap, and component scrap; and generating a set of scrap-related information associated with the unassigned scrap levels associated with the activity, where generating the set of scrap-related information includes calculating at least an activity scrap quantity and a total component quantity for the activity based, at least in part, on the following equations: A = M G * A A ⁢ % 100 ⁢ % - A A ⁢ % , where A represents an activity scrap quantity, M G represents yield, and A A % represents the activity scrap percentage, and M B = M G + M G * A A ⁢ % 100 ⁢ % - A A ⁢ % + … ⁢ ⁢ A fR + ( M G + M G * A A ⁢ % 100 ⁢ % - A A ⁢ % + A fR ) * A K ⁢ % / ( 100 ⁢ % - A k ⁢ % ) , where M B represents a total component quantity, A fr represents a fixed resource scrap percentage and A k represents a component scrap percentage.
