The application of the spaces states modeling method to the quality management of the titanium charge chloration process was described. Commit the total 6-level vertical structure of the system of information the process. System's state space was defined. It was breaks down, because there are two parallel processes (chlorination and the binding of oxygen oxides) on the superposition of 2-standard tasks. The features and restrictions on the use of mathematical models to solve this problem was described too.
