The book is a synthesis of new control thinking with process variability understanding. The diagnosis of abnormalities and the resolution of their causes are demonstrated for aluminum production plants, and a compendium of symptom/cause/correction responses is included for aluminum plant operators. Most narrated examples also demonstrate the interaction between human behavior and control, requiring a more scientific, questioning approach to the management of production. This approach is drawn from the authors' more than 25 years of experience, not only in metals plants but also in petrochemical and in food processing plants. Readers get a view into the human aspect of accidents and the problems of production.
