The three-year R&D project will result in a novel information technology applicable in large and complex industrial systems for process parameter monitoring, early detection and diagnosis of equipment and technology faults, as well as for the fast detection of malfunction roots. Operation support related to the optimal operation of process devices is offered. The system provides user-friendly and efficient interactive tools for storing technology-related knowledge, on-line modelling of process phenomena, visualisation of diagnostics information and for the on-line displaying of advisory documentation. In its final form the knowledge-intensive information technology will constitute a general-purpose, open architecture software shell. Through the application of the system, significant improvement is expected in the safety of industrial systems.
