Abstract:
1. A computer-implemented method of controlling a process for producing product within a range of at least one specification and product that are not within the range of at least one specification, the process having at least one input and at least one output that is affected by variation in at least one input, the method comprising: calculating the marginal revenue of producing one or more product within range of the at least one specification, one more product outside of the range of the at least one specification, and a variation about a mean of at least one measured variable of the at least one input and the at least one output; and varying the at least one input about the mean of at least one specification of the at least one measured variable so that the at least one output affected by the at least one input is optimized to where the marginal revenue of producing one more product within the at least one specification range is substantially equal to the marginal cost of producing one more product outside the at least one specification range.
