Functional model builder for qualitative and structural analysis

The aim of the CHEM project was to develop and implement advanced Decision Support Systems (DSS) for process monitoring, data and event analysis, and operation support in industrial processes. The systems are synergistic integration of innovative software tools, which improve the safety, product quality and operation reliability as well as reduce the economic losses due to faulty states, mainly in refining, chemical and petrochemical processes.

The CHEM applications consist of integrated sets of software toolboxes that provide robust detection and diagnosis of process problems in real-time. The systems assist operators in assessing process status and responding to abnormal events. The project provides a flexible architecture and a methodology in order to facilitate the development of such applications on many processes.

Users of "Functional model builder for qualitative and structural analysis" toolbox can input the architectural model of their plant (Process and Instrumentation Diagram) by interconnecting components from a generic plant item database. The primary objectives are to create this database and to provide graphical means to utilise them and derive complex symbolic mathematical relations automatically.

- Generic Plant Item Database (incorporates physical characteristics);

- Interface to create graphical models using the database and syntactical validation;

- Means to derive behavioural models (for simulation);

- Interface to derive fault indicators to be tested in real time;

- Interface to derive structural fault detection and isolation ability from above results.

The project aims at creating an integrated interface to easily create models for plants and derive fault diagnostics specific results from it in symbolic equation forms. It also aims at providing means for the validation of these results through offline simulations and exporting the results for on-line implementation by other toolboxes. All these are implemented in a single integrated development environment and significantly reduce the time and cost of modelling and manual derivation of equations.
