Abstract: The predictive power of data science cannot be denied in today's businesses. It's predictive models and algorithms are considered as the most reliable methods to predict the probability real life events. However, in business we need to translate these predictive insights into actions and results to exploit the true value of our data science solutions. We need to apply optimization algorithms on top of these predictions to directly effects our business results. The latter is a step that only few businesses have made yet, and this is exactly where OR comes into play and completes the field of data science.
