Abstract

The present project concerns the establishment of integration strategies of continuous chemical processes in real time and the tools necessary for its implementation. Several chemical processes will be used for application, in addition to models of unitary operations, models of planning and production control will be proposed. Hierarchical structures will be defined, which aim to meet the objectives of control and economy, techniques of robust syntony as well as numerical algorithms of identification of the structure of models and of the resolution of problems of non-linear programming and complete mixed non-linear programming of huge capacity will be developed.
