Lesson 23 : Expectation – Standard deviation

You will have to modify a model throughout this lesson. You may already download the base model. Once you reach slide 6, you will have to pause the slideshow, open GAMS and modify the model before you watch the rest of the slides.

1) Theory and numeric example
                                                video(4 min)
2) Modify the model in GAMS on your own
    • open GAMS
    • run the model primal0_risk_base.gms
    • modify the model on your own by introducing the risk factor as an expectation-standard deviation with phi=0.5
    • you may use various values of phi and observe the results
3) Watch the detailed answer

If you did not succeed in modifying the model yourself once you watched the correction, you may download the correction : primal0_risk_standardDeviation.gms
