Prescriptive analytics addressing uncertainty in logistics: a tailored neural network approach
N. Gómez-Vargas, R. Blanquero, E. Carrizosa
Uncertainty in logistic decisions regarding the multiple parameters that model these problems- demands, travel times, etc.- requires of approaches within Operations Research (OR) that leverage auxiliary data (e.g., congestions or weather) to predict these parameters and then address decision-making. This falls into prescriptive analytics, which aim is at suggesting the best proactive options in order to take advantage of the predicted outcomes. For the multiple-output regression we chose neural networks (NNs) due to their ability of learning a continuous function that naturally captures the complex relationships between inputs and also jointly models dependencies in the outputs. The effectiveness of the prescriptions depends on how well the predictions are integrated with the OR problem. We present a tailored NN model that both accounts for the decision objective in its loss function and adapts to the structure of the problem, avoiding the propagation of unimportant information.

Visit Alhambra
Tomorrow, Thursday, we will visit the Alhambra. 1. At 7:00 p.m., buses will start leaving from the door of the Hotel Granada Center (in front of the door of the Faculty of Sciences) 2. Upon arrival, groups with guides will be organized. 3. There will be groups in English language. These groups will wait at the destination until the arrival of all buses. 4. After the visit to the Alhambra we will walk to the Carmen de los Mártires to have a cocktail. 5. On the way back, we can go back by bus, which will leave from the same place where they left us at the Alhambra. 6. Although the way to the Alhambra by bus seems long, it really is close to the city. We invite you, whoever wishes, to go down for a pleasant walk. 7. Do not forget to take your Alhambra ticket and your identity card or passport. The document must be the same whose number matches the ticket number you have.
