An integrated approach to process monitoring and data analysis

Abstract

The authors describe two architectures: the Automated Process Monitoring (APROM) System, which examines a large combination of trend charts and shows the symptoms of problems to the engineers by sending a high level message and a chart when a process variable is out of control; and the Interactive Data Extraction and Analysis (IDEA) System, which provides a simple menu interface to get a block of data from a local, or remote host database. Once the user receives the right data block, the user can interactively exercise many options of plots and statistical data analysis functions. An application is described by a profile which can be modified easily by users.<>
