Collaborative Effort at Process Data Analysis Stabilizes Production and Leads to Positive Changes in Organizational Culture

Project Overview

The Manufacturing & Development Section at the Wakayama Works was having difficulty eliminating variations in quality with the production of a certain high-value-added chemical. Since this chemical was made to order, the conditions (seasonal factors, etc.) were not consistent, and the batches were typically smaller than those for products that were in continuous production. Although the staff in charge had tried to analyze the data from this particular process to ascertain the quality of the chemical, these inspections were not always the desired results.

Therefore, it was decided that the Wakayama Works would work with Yokogawa to jointly conduct a detailed analysis of the relationship between this production process and product quality. Based on the findings of this analysis, they were able to base their production operations on final product quality estimates and succeeded in achieving these targets.
