Abstract

A multilevel hierarchical control system for a single end product multistage plant is under consideration. It is shown that a variety of models and/or hybrid modeling are reasonable for inferred key variable forming, monitoring and control. Because of the complexity, uncompleted information, large uncertainties and mixture of batch, semi-batch and continuous processes different control strategies are appropriate for each hierarchical level. Two level reactive scheduler is proposed. Integration of operational and business management is carried out at the top hierarchical level using Fuzzy Cognitive Maps (FCM) approach. Some results of practical application of the system are reported.
