Turning Lemons into Lemonade How Optimization Tools Help You Turn Questionable Data into Profitable Actions Oliver Bastert Senior Director FICO
© 2014 Fair Isaac Corporation. Confidential. There are no excuses anymore: Optimize your decisions even if the data is uncertain or unknown! 2

Confidential. ► Optimization allows you to take best business decisions, based on ► Your business constraints ► Your data ► Your KPIs ► Optimization can deal with ► Competing objectives ► Maximize profits and minimize (or constraint) costs ► Scarce resources ► Maximize production with a restricted amount of labor ► Data uncertainty ► Data might be uncertain, erroneous or unknown Optimization 3© 2014 Fair Isaac Corporation.

Hands on Robust Optimization ► Each link has two travel times associated with it ► The first number denotes the time without disruption and the second number adds a slowdown on the link Optimization with limited knowledge (4,4) (3,2) (6,3) (5,5) (3,1) (3,7) (5,3) (3,1) (3,4) A B 8

© 2014 Fair Isaac Corporation. Confidential. We have to, hence: ► How to make very good and feasible decisions under data uncertainty ► How to decide if some data is completely unknown? ► How can we avoid an incorrectly “over-optimized” (over-fitted) solution? ► Is there a more rigorous method than (Monte-Carlo) simulation? Data Challenges, So What? Since data is missing or available at arguable quality only, you don’t make decisions? 10
© 2014 Fair Isaac Corporation. Confidential. ► We usually have good knowledge about the uncertainty, like ► Bounds or estimates on (standard) deviation ► We have the power to take decisions / implement a strategy ► But the uncertainty is not under our control; it is controlled by our opponent ► Nature ► Competitor / Supplier / Customer ► Market Robustness means that we are prepared for (protected against) any realization of the uncertainty (within the given uncertainty model) Robust Optimization is like Playing a Game
© 2014 Fair Isaac Corporation. Confidential. ► Evaluate your risks ► What if my predicted inputs would be 10% off? ► Compute the best decision under a pessimistic view of the future ► Compute a very good decision under a likely view of the future ► An always feasible solution ► Measure costs of robustness (protection) ► How much does a robust solution cost me compared to the best/average case scenario ► Measure benefit of robustness ► Compare the robust solution to a worst case scenario ► (Monte-Carlo) simulations are expensive, robust optimization is not What Robust Optimization Gives You 12
© 2014 Fair Isaac Corporation. Confidential. ► The predicted orange point is not the truth! ► Robust optimization can optimize decisions over a range of possibilities ► As opposed to simulation, robust optimization can simulate over a set of posbilities Predicting Data with High Uncertainty 13
© 2014 Fair Isaac Corporation. Confidential. Scenario Based ► Assume a number of historical observations or future predictions for input data is given ► The robust solution is the best solution which is feasible for all scenarios ► Simulation gives you a solution for each scenario but not a solution for all scenarios Modelling the Uncertainty 14
© 2014 Fair Isaac Corporation. Confidential. Ellipsoid Definition and Confidence ► Maximum distance or deviation ► By increasing or decreasing the diameter we can model confidence ► The robust solution is the best solution which is feasible for all points in the ellipsoid Modelling the Uncertainty 15

Confidential. ► Evaluate the cost of robustness ► Understand trade-offs and sensitivities ► Adapt data and parameters to create and compare scenarios ► Visualize data and results for analysis ► Collaborate in a multi-user environment ► Customize to your needs ► Combine with predictive analytics and business rules Robust Optimization 16

A Case Study Production planning at a liquid oxygen/nitrogen plant, a very energy-intensive operation and critical to health of people (hospital demand has to be met) ► Power company offers an interruptible load contract ► Power company can suspend supply in periods of high demand (summer) ► A number of interruptions each month (8 hours each) ► Cost per kWh is lower than with uninterrupted contract Outcome ► Treat interruptions as uncertain variables ► Plan production so that even with the most evil-placed interruptions customer demand is satisfied Air Products and Chemicals 22
© 2014 Fair Isaac Corporation. Confidential. How Can Robust Optimization Help Me? ► Are you taking data driven decisions today? ► How certain are you about the correctness/quality of your data? ► Do you want to know the impact in case your data would not be perfect? ► Do you want to know how a safer/better strategy would look like? ► Do you want to know which data impacts your decisions the most? ► Do you want to know for which data you need to improve quality for improving your KPIs? 23
