Data mining: science, art or magic?
• What is the question?
• Is the answer in the data?
• Involvement & expectations?
• Where is the expert?
• Is there sufficient context?

Waste incinerationFriday 30 March 2012
Motivation
• Significant variation on the decisions taken by panel operators
• Variations in operator behavior are believed to have significant effects on important process KPIs such as steam flow
• Expertise of senior operators may not be fully exploited to assist more junior operators when difficult decisions need to be made
• Data of operator actions and their effects is readily available in todays data historians.
• There is a gap between the operational and managerial level that makes it difficult to implement performance optimal plant operation. It is hard for managers to relate operator behavior to process performance.
• A feasibility study has indicated that potential ROI of a decision support system is signficant

Differential operator team analysisFriday 30 March 2012
Results
• Determined influence factors for steam loss
• Differential operator analysis
! Across teams
! Problems due to inefficient shift handover
• Implementation of an operator advisory system (process GPS)
! Action advise
! Action insight
