Intelligent integrated plant operation system for Six Sigma

Six Sigma has been widely adopted in a variety of industries as a proven management innovation methodology to produce high-quality products and reduce the cost at all the levels of an enterprise. This paper proposes a plant operation system which can guide plant engineers and operators to pursue Six Sigma activities by providing supports for key elements of Six Sigma: measurement, analysis, improvement and control. Multivariate statistical process control (MSPC) techniques have been employed as key technologies for the system, along with the plant information systems. This paper also discusses the future research issues that should be addressed to implement the described system.
