10. Slide | 8 WHAT MEANS BIG DATA IN A PLANT ? Laboratory Information Management Systems Enterprise Resources Planning Distributed Control System Supervisory Control And Data Acquisition Computerized Maintenance Management Systems Historian Manufacturing Execution Systems Energy Management System BUT still very difficult to have a consistent and holistic view of plant operational performance !

11. Slide | 9 WHERE TO START? 1. Scope the problem and elaborate the right business question 2. Understand what can impact this question 3. Identify and collect the data that you could help to formulate the answer(s) 4. Create the data mining process that will hopefully help you to design a quantitative answer 5. Validate the answer and deploy it and check that you problem is indeed solve ! A good reference is the DMAIC (Define Measure Analyze Improve Control) improvement process

15. Slide | 1133 EXAMPLE VALUE EXTRACTED FROM BIG DATA Predict and understand root causes of breaks in paper sheets Use historical data to predict real-time steel quality Collect data from hatcheries and provides analytics features to decrease malformation rates SOURCE: Electricity Consumers Resource Council estimated the cost of August 213 blackout in US between $4.5 and $8.2 billions Increase yield and reduce scrap by 5% Paper making Chemicals Steel making Hatcheries Type of project Impact Forecast dynamic security of transmission grid Avoid costly curtailment of loads or generations; in the worst case avoid black-outs (several billions $) Predictive Maintenance project to enhance O&M services Reduced unplanned down time Cost saving of 10% (lower insurance costs) Wind mills Electrical network Analyze drilling operation data to increase ROP Faster drilling and less downtimes due to reduced well head failure E&P drilling operations Optimize use of energy in exothermic processes Reduce shutdowns and increases OEE by 5% Reduce energy costs by 15% Reduce malformation rates of fish by 20%

32. Slide | 30 IDENTIFICATION OF CORRELATIONS BETWEEN MEASUREMENTS

33. Slide | 31 WHAT EXPLAIN VARIABILITY OF KWH/T OF O2 ?

34. PREDICT THE KWH/T WITH OPERATION PARAMETERS Slide | 32 Learning set Test set

35. Slide | 33 DIAGNOSTIC OF THE ERROR WITH THE CUSUM Drift of the model starts here

36. Slide | 34 WHAT EXPLAINS THE DRIFT USING NON POWER PARAMETERS 1 2 Automatic Pareto analysis (1) and decision tree (2) helps us to diagnose the drift and understand which and how parameters explain the drift. Obvioiusly T plays a strong role in the model drift => we need to include it as an input in the model; we cannot change the T !

37. Slide | 35 KWH/T PREDICTIVE MODEL V2 By including the T we are much better to predict the KWh/T

38. Slide | 36 CONCLUSIONS Big data combined with predictive analytics can help to improve performance and maintenance of production assets Proven approach to support lean program or any other performance management program Data collection/quality remains a major roadblock in industrial applications Still a lack of understanding of what is big data and analytics Still a big gap between data scientists and business people Always think about the business value! KISS and 80/20 rules
