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!

This is the perfect example of a fruitful technological partnership serving our branches, people, and clients.
