In order to boost the performance of Facility Networks (Bank Branches, ATMs, Retail Stores, etc.) PRIMARY developed FLO (Facility Location Optimization). Taking under consideration the multiple parameters involved in the process of designing and merging Facility Networks, PRIMARY offers FLO as an integrated solution complemented with advanced software which achieves maximization of the overall performance of a Facility Network while satisfying the imposed constraints. The parametric optimization model allows incorporation of the ad-hoc objectives per implementation and also respects all rules involved in the Facility Network design process.
