We optimize our channels revenues thanks to Hexaly. Versatile, fast, and scalable, it helps us solve problems involving millions of decision variables in minutes. We estimate the resulting gains at up to 2% of the turnover per year. Beyond, the Hexaly team quickly acquired a deep understanding of the TV and advertising business, thus becoming a partner of choice. They bring us powerful software solutions but also precious quantitative insights helping TF1 make the right strategic decisions.

Preparing Fret SNCF train drivers’ schedules is a complex task involving many operational and regulatory constraints. To solve this highly combinatorial problem, we sought a solver capable of handling this complexity and providing high-quality solutions in short running times. Hexaly Optimizer was the best solver on the market for this task. It now allows us to compute new optimized plans every year and to adapt these schedules regularly to meet new requirements.

We use Hexaly Optimizer for several optimization problems, including scheduling door manufacturing in car factories and optimizing empty packaging return flows. What we appreciate most is the incomparable ease of modeling provided by Hexaly formalism. Besides, exchanging with the Hexaly team is always fruitful and pleasant.

We use Hexaly Optimizer in our timetabling and resource allocation solutions for universities. Assigning the right student to the right room with the right teacher is always challenging, with many complex constraints: room capacities, shared resources, course precedence, personalized curriculum, subgroups, and many others… But Hexaly Optimizer is a great engine. We are very glad with the results we have been able to get with it, even for large-size problems!

Luis Franco de Campos Pinto Co-Founder, Zero Gap

I have worked with Hexaly Optimizer to solve several large-scale optimization projects in highly dynamic environments, where Hexaly Optimizer has proven instrumental in finding high-quality solutions within minutes to satisfy the needs for dynamic re-planning. I have found that the unique expressiveness of Hexaly’s modeling API and the highly knowledgeable support team makes Hexaly my go-to choice for complex optimization problems.

We developed the Pasco supply chain optimization model using Hexaly Optimizer within a few days of work. Hexaly Optimizer provides outstanding solutions, as considered by Pasco planners, in just a few minutes of running times, while the number of variables is gigantic (tens of millions). We could not imagine such a feat being possible initially since state-of-the-art MIP solvers like CPLEX, Xpress, and Gurobi could not tackle the problem in hours. Now we know that using Hexaly, it's possible!
