Darwin Scheduler is a state of the art tool for optimizing pump operation that works by using genetic algorithm optimization to control nominated pumps during an extended period simulation (EPS). The genetic algorithm optimization technique works by evolving near optimal solutions over generations of trial solutions. To reach an optimal solution it is normally expected to have to evaluate tens of thousands of solutions, sometimes more. One problem with this fact is that EPS simulations can be time consuming, especially for larger or more complicated models, and therefore run times for Darwin Scheduler can be correspondingly long. These best practices and tips offer suggestions and recommendations for using Darwin Scheduler in order to get the best performance and results out of the tool.
