ABSTRACT:
A production control system wherein statistical determinations are continuously made on the basis of current manufacturing process data corresponding to preselected parameters of the product being manufactured. The control method includes a determination of the mean .+-.3 standard deviations of statistical samples. The method further includes the step of determining whether the mean .+-.3 standard deviation is within preselected permissible limits. Parameter determinations which are outside the permissible limits may be signalled for suitable action. In one form, the method includes the feedback of control signals to the manufacturing apparatus for effecting automatic corrective adjustment thereof when necessary. The determinations may be made by a statistical computer with information as to the product parameters being provided to the computer from conventional sensing devices.
