Abstract: Methods of controlling manufacturing processes manufacturing, for example, absorbent articles. A target parameter to be measured is established, as are acceptable conditions of the target parameter. The target parameter is detected with first and second replications of determinations of the condition of the goods using multiple independent determinors, for example multiple sensors, or multiple replications using a common determinator, for example software instructions for analyzing a full digital vision image. Multiple determinations are taken at sites which are selected for their prospects for indicating acceptable conditions of the parameter. The method includes developing a measurement strategy, programming a computer to use appropriate analysis tools to evaluate the determination signals, transmitting the signals to the computer, and processing the signals according to an appropriate method.
