Our Research

What we do…

We are interested in harnessing the power of operations research, predictive analytics, and prescriptive analytics methodologies, to develop decision support tools for applied problems.

Currently, our research has focused on two main methodological areas:

Combinatorial algorithms
Stochastic optimization and Uncertainty modeling

We work in combining both areas, focused on applications, to make robust decision support systems. The applications we are looking into right now are energy management and astronomical observatory operations. They look far away from each other, but similar techniques can help significantly improve the processes if both settings. And both have large amounts of data that we can use to train, test, and validate our developments.

Look into our Projects section for more information on our current projects, and Contact us if you want to participate in some of them.

Projects

Current applied research projects

One of our aims is to connect theory and practice in our research. These are the current projects in which we are involved, and that allows us to connect the two.

In these projects, we are using combinatorial optimization and stochastic modeling techniques to develop decision support tools in various settings.

Optimal Energy Storage Management

We are combining machine learning and stochastic optimization tools to develop optimal energy management systems for fotovoltaic generation with storage.

Predictive Maintenance

Developing tools for fault detection and diagnosis, in order to construct predictive maintenance systems.

Operations Research Tools for Observatory Operations

Using operations research methodologies, we are developing new tools for observatory operations.
