What our customers say about us
The optimization engine helps me every day to dispatch our customer orders. On top of saving me a lot of time that I can dedicate to other high-value-added tasks, it is really exciting to discover each day how the routes can be optimized and to contribute to bringing sustainable solutions for construction site soils.
We developed the Pasco supply chain optimization model using LocalSolver within a few days of work. LocalSolver 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 that such a feat was possible at first, since state-of-the-art MIP solvers like CPLEX, Xpress and Gurobi were unable to tackle the problem in hours. Now we know that using LocalSolver, it’s possible!
Optiretail designs an optimal Liquefied Natural Gas (LNG) supply chain, minimizing the total project cost from sourcing to delivery. This powerful digital solution based on LocalSolver allows ENGIE to reduce the cost of LNG distribution by up to 15% and foster the development of new uses for LNG.
This is the perfect example of a fruitful technological partnership serving our branches, people, and clients. Our teams at Caisse d’Epargne worked together with LocalSolver to build a new optimization engine to solve our credit optimization problems. The resulting solution, in production since 2016, is more generic, more scalable, easier to maintain, but also much fastest, with just a few seconds of running time to get optimal solutions.
Creating a bridge between Model-Based Systems Engineering techniques and Operations research required an optimization solver combining accessibility and performance. LocalSolver was a great choice in this context: thanks to its natural mathematical formalism and fast transparent algorithms it is a strong support for the elaboration of optimized system architectures against multi-perspective constraints. I warmly thank the LocalSolver team for its precious help regarding the constraints implementation.
We use LocalSolver for several optimization problems including the scheduling of door manufacturing in car factories and the optimization of empty packaging return flows. What we appreciate most is the incomparable ease of modeling provided by LocalSolver formalism. Besides, exchanging with the LocalSolver team is always extremely fruitful and highly pleasant.
We have been highly impressed by the ability of LocalSolver consultants to understand the details of our business in just a few weeks. Working with them was really easy and led to a perfect tool for building tailor-made advertising campaigns for our clients and maximizing our total revenue. Our internal sales really appreciate the pleasant and responsive graphical interfaces and the quality of optimization. Efficiency, responsiveness, and professionalism are values that LocalSolver truly cultivates. I am personally very proud that the project carried out with the Belgian subsidiary has become a reference for the JCDecaux Group.
This journey started more than two years ago and because of the excellent support provided by the LocalSolver team, POSAM has managed to win the project in a very competitive international tender where many the big names of supply chain optimization participated. Thank you again for all the effort that makes LocalSolver such a technically brilliant product and for the excellent level of support.
LAC (Logistics & Automation Consulting) has found more than an ally in its partner LocalSolver, the world’s best performing optimization engine for solving complex problems. LAC is able to take full advantage of the capabilities of LocalSolver, to develop custom solutions tailored around the customer’s problem, offering real bespoke software delivering high performance results. Finally, InTime was born from this partnership, LAC software for the optimized planning of truck loads and deliveries, generating savings of up to 20% of the direct costs of the activity for its users.
Your services were a crucial help for our project, and we have total confidence in Julien who, over the years, continues to impress me with the quality of his work, his versatility and his professionalism! True added value and innovative technology.
We use LocalSolver in our timetabling and resource allocation solutions for universities. Assigning the right student to the right room with the right teacher is always a challenging task, with many complex constraints : room capacities, shared resources, course precedence’s, personalized curriculum, subgroups and many others… But LocalSolver is a great engine. We are very glad with the results we have been able to get with it even for large size problems!
I have worked with LocalSolver to solve several large-scale optimization projects in highly dynamic environments, where LocalSolver has proven instrumental for finding high-quality solutions within minutes to satisfy the needs for dynamic re-planning. I have found that the unique expressiveness of LocalSolver’s modelling API and the extremely knowledgeable support team makes LocalSolver my go-to choice for complex optimization problems.
The innovating features of LocalSolver and its unique modeling formalism have allowed us to solve numerous problems on which we could not find satisfying solutions with MIP solvers. LocalSolver’s performance surpasses greatly our expectations on the TSP, matching and facility location problems we’re working on. In one year, we have optimized € 160 million with an average gain of 12%. The reactive and precise support given by Nikolas has greatly helped us in moving forward quickly on our projects.
LocalSolver was first in mind, given our long-standing relationship and their recognised expertise in operational research, when we wanted to quantify our resilience to COVID-19.

We were looking for an optimizer to solve our large out-of-home media planning problems. After a benchmark against CPLEX, LocalSolver proved to be the best performing solver; it could handle large-scale problems and find high-quality solutions in minutes. It enabled us to deploy our media planning solution at Ocean Outdoor, a UK premium DOOH operator. The ultra-competitive pricing they offered us allowed us to build a long-term partnership.
LocalSolver has been tested and confirmed by our team as the best GLOBAL optimizer available on the market. With this optimizer and innovative approaches, the Maxflow app has a superior optimization capability for its automated workflows.
Preparing Fret SNCF train drivers’ schedules is a complex task involving many operational and regulatory constraints. To solve this highly combinatorial problem we were looking for a solver capable of handling this complexity and providing high-quality solutions in short running times. LocalSolver was the best solver on the market for this task. It now allows us to compute new optimized plannings every year and to adapt these schedules regularly to meet new requirements.
Before introducing the shipment management application, the problem of mixing and packing a large number of raw materials was managed by experts in Excel. Today, thanks to LocalSolver, the application provides high-quality solutions in a short time. This has allowed us to save money while reducing work time and dependence on skilled workers. It is an major step in the digital transformation of our department.
We have been working with the LocalSolver team for several years now. Their expertise in network design problems has allowed us to move forward with our fiber network design problem. In addition, LocalSolver’s agile methodology is very valuable, as it permits us to quickly iterate on the solution based on operational feedback.
Developing and deploying a tool like Smart Agri took less than three years. This digital simulation and optimization tool for integrated and organic fertilization was initiated mid-2015 and has today reached the phase of an initial business solution rollout.
