Quality Control in a Semi-Continuous Polymer Production Process

Summary: [This abstract is based on the authors' abstract.] When the sources of product quality variation are unknown or uncontrollable, several checkpoints along the production line are used to validate product quality. In a semi-continuous polymer production process, the historical records from these checkpoints are used to determine the possibility of reducing the number of measurements taken. By subjecting the data to various statistical analyses, some correlations among the measurements are detected. A change in the focus of the quality control system can assure long-term process improvement.
