Operating Culture Impact on APC Application Design: Approaches and Case Study

Consulting engineers are well aware of large variations in plant operating cultures between countries, companies, and even within sites and operating crews. These operating cultures must be considered when designing Advanced Process Control (APC) applications in order to maximize utilization rates and return on investment. Designs must be driven by an understanding of the totality of unit operations. Economic factors, equipment constraints, management philosophy, maintenance department responsiveness, instrumentation reliability, operating crew skills and teamwork, and individual operator concerns are all important and must be considered during application design. A general approach to incorporating operating culture considerations into APC application design is described. A case study for an iron ore concentrator plant is presented.
