Victor Cohen

PhD Student / CERMICS


I am a PhD student in Operations research and Machine learning at CERMICS, Ecole des Ponts ParisTech. With my advisors Frédéric Meunier and Axel Parmentier , we are working on the logistic of predictive maintenance.

I joined Laboratory for Information and Decision Systems (LIDS) at MIT as a visiting student under the supervision of Patrick Jaillet from October 2019 to December 2019. I worked on online optimization topics.

Research Topic

This PhD focuses on the optimization of the logistic of predictive maintenance.

Device failures is one of the main sources of cost in the industry. It is notably the case for airlines, because if a failure occurs, flights must be canceled, which leads to costs that are often much higher than the price of replacing this equipment. The objective of predictive maintenance is to exploit available data to predict when the next failure will occur. Based on this information, the airline must schedule the next maintenance operations that are going to be done.

This problem can be formulated as a Partially Observed Markov Decision Process (POMDP). We study some methods to solve a POMDP with a Linear Program using probablistic graphical models.
