The operator of the French electricity transmission system should plan the maintenance operations, some interventions require the power supply to be cut off, guaranteening the electricity supply. The risk values are calculated for different future scenarios. Our optimization problem is the following: given the risk values, the goal is to find an optimal planning regarding a risk-based objective. Moreover, this planning must be consistent with all job-related restrictions such as resource constraints. The objective function includes the average risk, over time and scenarios, and a measure of the cost variability, expressed by a quantile of the risks. Our approach generates first a set of good solutions by solving integer linear models whose objective functions are approximations of the actual objective. These solutions then go through an improvement phase, which includes a VNS and a PR algorithm. The computational study shows that the procedure obtains high quality solutions.

Keywords: integer programming; maintenance planning; metaheuristic algorithms; VNS;

    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.
