OCTOGRAPH (O.) is a control performance assessment and design optimisation platform developed by I N N O V A T I O N [ X ]. O. has been applied to industrial application globally to assess the current performance of the control schemes installed within operational processes. O. then develops the optimal design couplings to achieve the process objectives for the industrial plant. O. is non invasive to the process, resulting in a plant-wide control performance assessment with no process disturbances or lost production.
