Patent ID: 8290606

Claim:
A method, using a computer hardware system, for controlling cancelled orders in a manufacturing environment, the method comprising: receiving, using the computer hardware system, a cancellation of an order in the manufacturing environment; reading, using the computer hardware system, a list of work units associated with the order; obtaining, using the computer hardware system, at least one identifying attribute of each work unit in the list of work units associated with the order; reading, using the computer hardware system, a space maximum value associated with the at least one identifying attribute of each work unit; reading, using the computer hardware system, a stock maximum value associated with the at least one identifying attribute of each work unit in the list of work units associated with the order; determining, using the computer hardware system, a current stock value associated with the at least one identifying attribute of a first work unit in the list of work units associated with the order; if the current stock value is less than the space maximum value and the stock maximum value, setting, using the computer hardware system, a valid cancel optimization status indicator for the first work unit; retrieving, using the computer hardware system, a cancel optimization model record matching at least one identifying attribute of a first work unit in the list of work units associated with the order; and, applying using the computer hardware system, the retrieved optimization model record to the first work unit in the list of work units to modify a process routing map of the first work unit.
