Process optimization through integration of control and asset management / O.A. Akintunde

This research work focuses on the use of integrated control and asset management (ICAM) in optimizing process plant operations. The assets considered are mainly valves and instruments, such as pressure, flow, temperature and level transmitters. The dissertation discusses how integrated control and...
