Abstract
The control systems in production plants are structured hierarchically into several layers, each operating on a different time scale business-management, production and process level. In this article simulation model of the polymerization plant was presented to help developing a production control. The model was designed in Matlab, Simulink and Stateflow simulation environment. With the model it is possible to simulate the execution of scheduled jobs in production and to investigate and verify the plant wide control algorithms. In the model the process of retrieving the production Performance Indicators (pPI) is included, which are used to obtain information about current status of the production process. These indicators are also used to control the production process. Hierarchical closed-loop control scheme was proposed. Some preliminary results demonstrate the usefulness of the proposed methodology.
