A number of transportation studies have adopted data-driven optimization approaches. Most of the studies employ a two-step approach: in the first step, machine learning models are used to predict the values of uncertain parameters; in the second step, the predicted values are used as input for an optimization model to derive a decision. However, such a two-step approach is flawed in several aspects. In the past three years, we have witnessed a number of methodological developments in the operations research literature that address the deficiencies of the two-step approach. This seminar will introduce a few of the methodological techniques that are widely applicable in practice and easy to implement by those without much operations research background.
