Key performance indicators in plant-wide control

To improve production performance it is necessary to define production goals with a proper implementation strategy and a suitable closed-loop control for their achievement. A promising solution is the use of the Key Performance Indicators (KPIs) approach. To verify the idea of production feedback control using production KPIs as referenced controlled variables, a procedural model of a production process for a polymerisation plant has been developed. The model has been used during a number of simulation runs performed with the aim of developing and verifying the idea of KPI-based production control.
