System reconfigurability 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.

The objective of "System reconfigurability analysis" Toolbox is to suggest recovery decisions in case of fault occurrences in order to allow continuing the production in a degraded mode. These advices can be new remedial operations or operation directives. They are displayed to the operators on a graphical user interface or they are sent to other toolboxes such as "State transition support" toolbox.

The toolbox consists of two parts. The first part is a model builder that enables a designer to produce a functional model of the plant. It works off-line. The second part of the toolbox is used on-line. It is a reconfiguration possibility analyser based on artificial intelligence techniques. It analyses the faults that it has received and provides recovery decisions as outputs.
